Description

Applicable under Article 30, Paragraph 2 of the Patent Act. Published on January 12, 2023 (https://apps.apple.com/us/app/color-select/id1663995983). Published on the website on May 16, 2023 (https://colorbiz.co.jp/service_houjin.php).

The present invention relates to a system, a user terminal, a program, and a method.

Hair coloring, the act of dyeing hair, has been widely practiced for some time. In beauty salons and hair coloring specialty stores, when coloring hair, the hairdresser checks the condition of each customer's hair and then prepares a hair coloring agent according to the customer's request. However, there is no way to objectively confirm what color the hair will be after dyeing with the prepared hair coloring agent, so the hairdresser must guess the color of the dyed hair based on their experience and intuition.

In light of this, a selection system has been disclosed that quickly presents users with hair coloring agents that will achieve their desired color (for example, Patent Document 1). In the selection system, the coordinate data of each color space when dyeing is performed using a non-mixed material that is a single hair coloring agent, and a mixed material in which multiple hair coloring agents are mixed in a specified mixing ratio, is recorded for each type of undercolor. Therefore, when the type of undercolor and desired color of the person to be dyed are input, a non-mixed material or mixed material whose coordinate values match or are close to the input desired color can be searched for from the coordinate data corresponding to the input type of undercolor, and the search results can be output.

The terminal may be installed in a store such as a beauty salon or a hair coloring specialty store that performs hair coloring for customers, or may not be installed in the store and may be carried by an individual. One store may have one terminal, or multiple terminals may be installed in one store. For example, multiple terminals may be installed in one store, and multiple hairdressers belonging to one store may each use a different terminal.

[Device configuration]
The terminal is not particularly limited as long as it is a computer device having a display screen and an input unit. The terminal may be a stationary type installed in a store office or the like, or a portable type that the user can carry with them when moving around. Examples of terminals include conventional mobile phones, tablet terminals, smartphones, mobile terminals, desktop and notebook personal computers, etc.

Figure 1 is a block diagram showing the hardware configuration of a terminal 10 according to a first embodiment of the present invention. The terminal 10 includes a control unit 11, a RAM 12, a storage unit 13, an input unit 14, a display unit 15, and a communication interface 16, all of which are connected to each other via an internal bus.

The control unit 11 is composed of a CPU and a ROM. The control unit 11 executes programs stored in the storage unit 13 and controls the terminal 10. The RAM 12 is the work area of the control unit 11. The storage unit 13 is a storage area for saving programs and data. In other words, the storage unit 13 functions as a recording medium that stores programs. The control unit 11 performs arithmetic processing based on the programs and data read from the RAM 12, and the data inputted by the input unit 14.

The display unit 15 has a display screen. The control unit 11 outputs a video signal for displaying an image on the display screen according to the result of the arithmetic processing. Here, the display screen of the display unit 15 may be a touch panel equipped with a touch sensor. In this case, the touch panel functions as the input unit 14. The communication interface 16 can be connected to the communication network 4 wirelessly or via a wire, and can transmit and receive data to and from other computer devices via the communication network 4. Data received via the communication interface 16 is loaded into the RAM 12, and arithmetic processing is performed by the control unit 11.

[Amount Specification Processing]
The amount specification process according to the first embodiment will be described. In the amount specification process, the amount (numerical value O) of each of the first hair coloring agent or the second hair coloring agent (element E) contained in the hair coloring agent is specified based on the calculation rule R and the numerical value I that have been input. The element E corresponds to each of the first hair coloring agents or the second hair coloring agents to be calculated. An element E of one may correspond to a plurality of first hair coloring agents or a plurality of second hair coloring agents to be calculated. The numerical value O corresponds to the amount of the first hair coloring agent or the second hair coloring agent to be calculated. The numerical value O of one may correspond to the amount of the plurality of first hair coloring agents or the plurality of second hair coloring agents to be calculated.

The amount determination process is used, for example, by a user to calculate the amount of the first hair coloring agent or the second hair coloring agent. Specifically, a store clerk at store 1 counsels a customer and creates an instruction sheet that includes the hair coloring agent mixture. Then, the process is executed when store clerk at store 1 or store clerk at store 2 calculates the amount of the first hair coloring agent or the second hair coloring agent based on the instruction sheet.

FIG. 2 is a diagram showing a flowchart of the amount specification process according to the first embodiment of the present invention. First, the user starts an application program downloaded to the terminal 10. The user inputs information required for calculation on the input screen displayed on the terminal 10. The terminal 10 accepts input of calculation rules R ₂ , R ₃ , . . . R _n-1 , R _n and input of numerical values I ₁ , I ₂ , . . . I _n-1 , I _n for the first hair color agent or the second hair color agent (step S1). In step S1, the terminal 10 may accept input of a total value T _n or a total amount of the hair color agent. The total value T _n indicates the total value of n numerical values O ₁ , O ₂ , . . . O _n-1 , O _n . The total value T _n is the total amount of the first hair color agent or the second hair color agent. In step S1, the terminal 10 may accept input of group information related to the calculation.

In step S1, the terminal 10 accepts input of one of the calculation rules R ₂ , R ₃ , ... R _n-1 , R _n by selecting one operation button. The selection of one operation button includes both selection by operating the terminal 10 such as a touch panel, and selection by operating an external device such as a keyboard or controller. The terminal 10 stores a plurality of types of calculation rules R in association with a predetermined symbol. The user can input the calculation rule R to the terminal 10 by selecting a predetermined symbol as one operation button. The specific calculation rule R and the display screen for input will be described later.

When the input of the calculation rules R ₂ , R ₃ , ... R _n-1 , R _n and the input of the numerical values I ₁ , I ₂ , ... I _n-1 , I _n are accepted, the terminal 10 executes the calculation process of the large group (step S2). When the calculation process of the large group is executed, the terminal 10 judges whether or not a small group exists for the calculation rule R and the numerical value I input in step S1 (step S3). If a small group exists (YES in step S3), the terminal 10 executes the calculation process of the small group (step S4). When step S4 is executed, the terminal 10 executes the process of step S3 again.

If no small group exists (NO in step S3), the amount (numerical value O) of each of the first hair coloring agent or the second hair coloring agent identified in steps S2 and S4 is output (step S5). In step S5, the ratio of each of the first hair coloring agent or the second hair coloring agent to the total amount of hair coloring agent and/or the ratio of the amount of the first hair coloring agent or the second hair coloring agent to the total amount of hair coloring agent may be output. Examples of output in step S5 include display on a display screen and audio output. The amount specification process is completed by the above steps S1 to S5. The amount specification process is performed for each of the first hair coloring agent and the second hair coloring agent.

Groups (large groups and small groups) related to calculations will be described. A group is a group of calculation rules for which calculations are performed by a single calculation process. A group includes one or more calculation rules. A large group is a group for which calculations are performed with the highest priority. A small group is a group for which calculations are performed after the large group. There may be multiple small groups. There is no particular limit to the order in which calculations are performed between small groups. There may also be a group for which calculations are performed after a small group. The program according to the first embodiment is capable of grouping multiple first hair color agents or multiple second hair color agents and performing calculations.

In the first embodiment, the total value T _k indicates the total value of k numbers, i.e., numbers O ₁ , O ₂ , ..., O _k-1 , O _k . In addition, for a calculation rule R, a number I, and a number O, the calculation rules R, numbers I, and numbers O having the same number or letter as a subscript indicate that they correspond to each other. In addition, the numbers in the subscript may be specified according to the area entered on the display screen of the terminal 10, or may be specified in the order entered by the user into the terminal 10 in step S1.

The terminal 10 calculates a numerical value O _k based on the total value T _k and the numerical value I _k according to a predetermined calculation rule R _k . The terminal 10 repeats the process of calculating the numerical value O _k in order from k=n until k=2. In this way, the terminal 10 calculates numerical values O ₁ , O ₂ , ... O _n-1 , O _n . n and k are integers equal to or greater than 2, and k is equal to or less than n. Specifically, when the total value T ₅ is a predetermined amount (for example, 100 g), the terminal 10 executes the calculation process in the order of calculation rule R ₅ to calculation rule R _2. The terminal 10 calculates the numerical value O in the order of numerical values O ₅ , O ₄ , O ₃ , O ₂ , O ₁ .

In the first embodiment, the calculation rule R is any one of ratio calculation, percentage calculation, gram calculation, and magnification calculation. The calculation rule R _α is a ratio calculation. α is an integer equal to or greater than 2, and α is equal to or less than n. The calculation rule R _ε is a percentage calculation, magnification calculation, or gram calculation. ε is an integer greater than α, and ε is equal to or less than n. In one quantity specification process, multiple calculation rules R may be used, or different calculation rules R may be used in combination. Specifically, in one quantity specification process, the calculation rule R of the ratio calculation and one or more calculation rules R of the percentage calculation, gram calculation, and magnification calculation may be used.

Figure 3 is a diagram showing an example of a display screen according to the first embodiment. The display screen 100 shown in Figure 3 is a display screen output in step S5. The display screen 100 is also a display screen for inputting the calculation rule and numerical values in step S1. The display screen 100 displays a first substance display field 111, an input field 112, a usage amount display field 113, a second substance display field 121, an input field 122, and a usage amount display field 123.

The first substance display field 111 and the second substance display field 121 are display areas for element E. The first substance display field 111 and the second substance display field 121 display the name of a substance or a number. The type of the first hair coloring agent may be input in the first substance display field 111, or the type of the first hair coloring agent may not be input and numbers may be displayed in order from the top of the display screen 100. The second substance display field 121 may display the type of the second hair coloring agent, or the type of the second hair coloring agent may not be input and numbers may be displayed in order from the top of the display screen 100.

As shown in the figure, numbers are displayed in order from the top of the display screen 100 in the first substance display field 111 and the second substance display field 121. The numbers displayed from the top of the display screen 100 correspond to elements E ₁ , E ₂ , ..., E ₅ , and E _6. If a small group exists (YES in step S3), the element E may include multiple elements in the calculation process of the large group. For example, the element E' of the large group and the numerical values I' and O' corresponding to the element E' are set in correspondence with the input field 112 in which the calculation rule R is input. In FIG. 3, the correspondence relationship between the element E' and the element E is as follows. The element E' ₁ corresponds to the element E ₁ , the element E' ₂ corresponds to the elements E ₂ to E ₃ , the element E' ₃ corresponds to the elements E ₄ to E ₆ , and the element E' ₄ corresponds to the element E ₇ .

The input fields 112 and 122 are areas for inputting a calculation rule R and a numerical value I. In the input fields 112 and 122, symbols indicate the calculation rule R, and numbers indicate the numerical value I. The calculation rule 112X and numerical value 112Y are input in the input field 112a. The symbols correspond to the symbols displayed on the operation buttons. When any of the input fields 112 and 122 are selected, a list of multiple symbols and/or multiple numbers is displayed on the terminal 10. The user can input a calculation rule and a numerical value into the input fields 112 and 122 by selecting the desired symbol and inputting the desired numerical value.

As the calculation rule R, for example, ":" indicating a ratio calculation, "%" indicating a percentage calculation, "x" indicating a magnification calculation, or "g" indicating a gram calculation can be entered, followed by a numerical value I. Numeric values such as "1", "3", and "5" are displayed to the right of the symbols such as ":", "x", "g", and "%" in the calculation rule R. The numerical values are positive values and may include decimals.

The calculation rule 112X and the numerical value 112Y input in the input field 112a, the numerical value displayed in the usage amount display field 113a, and the substance in the first substance display field 111a are displayed in the same row. The calculation rule 112X and the numerical value 112Y input in the input field 112a, and the numerical value displayed in the usage amount display field 113a correspond to the substance (element E) in the first substance display field 111a. In the first embodiment, the terminal 10 can display in a manner that makes it possible to understand that the calculated numerical values O ₁ , O ₂ , ... O _n-1 , O _n correspond to the elements E ₁ , E ₂ , ... E _n-1 , E _n , respectively, and/or correspond to the numerical values I ₁ , I ₂ , ... I _n-1 , I _n, respectively.

By selecting the icon 106a, the user can display the previously set calculation rule R. For example, the terminal 10 can display input fields 112, 122 that have been previously grouped, or input fields 112, 122 in which the calculation rule R has been previously input.

The user can group the first hair coloring agent or the second hair coloring agent by selecting icon 106b. The user can set an element E' that includes multiple elements E by selecting two or more elements E. Specifically, the user selects icon 106b, and then selects input fields 112b and 112c. As a result, "2" and "3" corresponding to the first substance display fields 111b and 112c are grouped, and input field 112h is displayed. In the first substance of FIG. 3, a large group of 1 (input fields 112a, 112h, 112i, 112g) and a small group of 2 (input fields 112b, 112c and input fields 112d, 112e, 112f) are displayed.

Below, the content of each calculation process for ratio calculation, percentage calculation, gram calculation, and magnification calculation will be explained along with the display screen of the terminal 10.

[Ratio calculation]
The ratio calculation (calculation rule R _α ) is a calculation for distributing the amount (numerical value O) of the first hair color agent or the second hair color agent, for which a ratio has been input, to the total amount of the first hair color agent or the second hair color agent according to the input ratio. The input ratio corresponds to the numerical value I. Specifically, the calculation rule R _α calculates numerical values O ₁ , O ₂ , ... O _α-1 , O _α corresponding to the numerical values I ₁ , I ₂ , ... I _α-1 , I _α , respectively, based on the ratios of the numerical values I ₁ , I ₂ , ... I _α-1 , I _{α ,} such that the sum of the numerical values O ₁ , O ₂ , ... O _α-1 , O _{α becomes the total value T α} . Each ratio of the numerical values I ₁ , I ₂ , ..., I _α-1 , and I _α means the numerical values I ₁ :I ₂ :I ₃ : ...:I _α-1 :I _α . In a ratio calculation, two or more numerical values I are input in one ratio calculation, and a numerical value O corresponding to the input numerical values is calculated.

For example, the calculation rule ":" entered in input fields 112b and 112c indicates a ratio calculation. The numerical value "3" entered in input field 112b and the numerical value "2" entered in input field 112c are numerical values I corresponding to the ratio calculation. In other words, it is entered that the first hair coloring agents "2" and "3" corresponding to the first substance display fields 111b and 111c are calculated in a ratio of "3:2". In the case of a ratio calculation, the calculation rule ":" must be entered in all input fields that are the subject of the ratio calculation. In other words, ":3" and ":2" must be entered in input fields 112b and 112c. There is no particular limitation on the elements that are the subject of the ratio calculation, as long as they are 2 or more.

The usage amount display fields 113 and 123 are display areas for the numerical value O. As shown in the figure, the usage amount display fields 113b and 113c display "4.3 g" and "6.4 g". The numerical value O displayed in the usage amount display fields 113b and 113c is calculated based on the calculation rule R and the numerical value I entered in the input fields 112b and 112c. Specifically, the numerical value O displayed in the usage amount display fields 113 and 123 displays the specified amount of the first or second hair coloring agent used (numerical value O) based on the information entered in the total amount display field 101, the first substance total amount display field 102, the second substance total amount display field 103, and the input fields 112 and 122, which will be described later.

[Percentage calculation]
The ratio calculation (calculation rule R _β ) is a calculation for specifying the amount of the first hair color agent or the second hair color agent for which a ratio is input according to an input ratio. Specifically, the calculation rule R _β is for calculating a numerical value O _β based on a ratio specified by the numerical value _{I β to the total value T β-1 of ( β-1} ) numerical values O ₁ , O ₂ , ... O _β-1 , such that the sum of the numerical values O 1 , O 2 , ... O _β-1 , O _β becomes the total value T β. Alternatively, the ratio calculation is for calculating a numerical value O _β based on a ratio specified by the numerical value I _β to the total value T _β . _β is an integer equal to or greater than 3, β is greater than α, and β is equal to or less than n.

For example, the percentage calculation may specify the amount of the first or second hair coloring agent, which is a percentage specified by the input numerical value (numerical value I _β ), relative to the total amount of the first or second hair coloring agent input up to the input of the percentage (total value T _β-1 ), as the amount (numerical value O _β ) of the first or second hair coloring agent (element E _β ) for which the percentage has been input. Alternatively, the percentage calculation may specify the amount of the first or second hair coloring agent, which is a percentage specified by the input numerical value (numerical value I _β ), relative to the total amount of the first or second hair coloring agent input up to the input of the percentage (total value T _β ), as the amount (numerical value O _β ) of the first or second hair coloring agent (element E _β ) for which the percentage has been input.

Alternatively, the percentage calculation may specify the amount of the first hair coloring agent or the second hair coloring agent, which is a proportion specified by the input numerical value (numerical value I _β ), relative to the total amount of the first hair coloring agent or the second hair coloring agent selected by the user, as the amount (numerical value O _β ) of the first hair coloring agent or the second hair coloring agent (element E _β ) for which a proportion has been input. Alternatively, the percentage calculation may specify the amount of the first hair coloring agent or the second hair coloring agent, which is a proportion specified by the input numerical value (numerical value I _β ), relative to the total amount of the first hair coloring agent or the second hair coloring agent selected by the user and the first hair coloring agent or the second hair coloring agent for which a proportion has been input, as the amount (numerical value O _β ) of the first hair coloring agent or the second hair coloring agent (element E _β ) for which a proportion has been input. In the percentage calculation, a numerical value I of 1 is input and a numerical value O of 1 is calculated in one percentage calculation.

For example, the calculation rule "%" entered in input field 112f indicates a percentage calculation. The numerical value "40" entered in input field 112f is numerical value I corresponding to the percentage calculation. In FIG. 3, the first hair color agent "6" corresponding to the first substance display field 111f is calculated as a percentage of "40%" of the total amount of the numerical values displayed in the usage amount display fields 113d and 113e.

[Magnification calculation]
The magnification calculation (calculation rule R _β ) is a calculation for specifying the amount of the first hair color agent or the second hair color agent for which the magnification has been input, according to the input magnification. Specifically, the same calculation rule R _β as the ratio calculation can be used. For example, the magnification calculation may specify the amount of the first hair color agent or the second hair color agent obtained by multiplying the total amount of the first hair color agent or the second hair color agent input before the magnification is input (total value T _β-1 ) by the magnification specified by the input numerical value (numerical value I _β ), as the amount (numerical value O _β ) of the first hair color agent or the second hair color agent for which the magnification has been input (element E _β ). Alternatively, the magnification calculation may specify the amount (numerical value O _β ) of the first or second hair coloring agent (element E _β ) for which the magnification has been input, such that the amount of the first or second hair coloring agent obtained by multiplying the total amount (total value T β-1 ) of the first or second hair coloring agent input up to the input of the magnification by the magnification specified by the input numerical value (numerical value I _{β )} becomes the total amount (total value T _β ) of the first or second hair coloring agent input up to the first or second hair coloring agent for which the magnification has been input.

Alternatively, the magnification calculation may specify the amount of the first hair coloring agent or the second hair coloring agent (element E _β ) for which the magnification has been input, as the amount (numerical value O β ) of the first hair coloring agent or the second hair coloring agent for which the magnification has been input, which is the amount of the first hair coloring agent or the second hair coloring agent selected by the user multiplied by the magnification specified by the input numerical value (numerical value I _β ). Alternatively, the magnification calculation may specify the amount (numerical value O _β ) of the first hair coloring agent or the second hair coloring agent for which the magnification has been input, such that the amount of the first hair coloring agent or the second hair coloring agent selected by the user multiplied by the magnification specified by the input numerical _value ( _{numerical value I β )} is the total amount of the first hair coloring agent or the second hair coloring agent for which the magnification has been input and the first hair coloring agent or the second hair coloring agent selected by the user. In the magnification calculation, a numerical value I of 1 is input and a numerical value O of 1 is calculated in one magnification calculation.

For example, the calculation rule "x" entered in input field 112i indicates a multiplication factor calculation. The numerical value "2" entered in input field 112i is numerical value I corresponding to the multiplication factor calculation. In FIG. 3, the total amount of the first hair coloring agents "4," "5," and "6" corresponding to first substance display fields 111d to 111f is calculated to be "twice" the total amount of the first hair coloring agents "1," "2," and "3" corresponding to first substance display fields 111a to 111c.

[Gram calculation]
The gram calculation (calculation rule R _γ ) is a calculation that specifies the amount of the first hair color agent or the second hair color agent of an input value I (grams). Specifically, the calculation rule R _γ calculates the value I _γ to be a value O _γ , where γ is an integer equal to or greater than 3, γ is an integer greater than α, and γ is equal to or less than n. In the gram calculation, in one gram calculation, a value I of 1 is input and a value O of 1 is calculated.

For example, the calculation rule "g" entered in input field 112g indicates gram calculation. The numerical value "5" entered in input field 112f is numerical value I corresponding to gram calculation. In FIG. 3, the amount displayed in usage amount display field 113g of the first substance "7" corresponding to first substance display field 111g is calculated to be "5g."

Returning to the explanation of the display screen 100 in FIG. 3, the display screen 100 displays a total amount display field 101, a first substance total amount display field 102, and a second substance total amount display field 103. The total amount display field 101 displays the total amount of the hair coloring agent. The first substance total amount display field 102 and the second substance total amount display field 103 display the respective total amounts of the first hair coloring agent and the second hair coloring agent, and the ratio of the first hair coloring agent and the second hair coloring agent.

The user can change the ratio of the first hair coloring agent to the second hair coloring agent at will. For example, by selecting the icon 104a, the ratio of the first hair coloring agent to the second hair coloring agent can be increased. The first hair coloring agent, the second hair coloring agent, or the total amount of the hair coloring agent may be increased or decreased by inputting an operation to the terminal 10. When the ratio of the first hair coloring agent to the second hair coloring agent, or the first hair coloring agent, the second hair coloring agent, or the total amount of the hair coloring agent is increased or decreased, the amount of the first hair coloring agent and the second hair coloring agent displayed in the usage amount display field 113, 123 is changed while maintaining the calculation rule R and the numerical value I in the input field 112, 122. In other words, the amount of the first hair coloring agent and the second hair coloring agent can be calculated by changing the ratio or total amount of the first hair coloring agent and the second hair coloring agent while maintaining the respective proportions or ratios of the first hair coloring agent and the second hair coloring agent.

For example, when the user selects percentage calculation in input field 112f, the user may be able to select one or more of input fields 112a to 112f. The terminal 10 can calculate the value in usage amount display field 112f by multiplying the total amount of the values in usage amount display field 113 corresponding to the selected input field 112 by the percentage specified by the value entered in input field 112f. The user can select which total amount of the first substance the percentage entered in input field 112f should be calculated for. The same applies when the user selects magnification calculation in input field 112.

When a user selects an element to be the subject of a ratio calculation or a magnification calculation, the calculation rule R _β calculates a numerical value O _β based on a ratio specified by the numerical value I _{β to the total value T δ of} the δ numerical values of the numerical values O ₁ , O ₂ , ... O _δ . Or, when a user selects an element to be the subject of a ratio calculation or a magnification calculation, the calculation rule R _β calculates a numerical value O _{β based on a ratio of the numerical value I β to the total value T δ of the} δ numerical values of the numerical values O ₁ , O ₂ , ... O _{δ and the total value of the numerical value O β .} β is an integer of 3 or more, β is n or less, and δ is (β-1) or less. In this case, the δ numerical values of the numerical values O ₁ , O ₂ , ... O _δ do not have to be consecutive numerical values. In addition, the δ numerical values of the numerical values O ₁ , O ₂ , ... O _δ are numerical values O corresponding to the input field 112 selected by the user.

In addition, the information displayed and input in the first substance display field 111 and the second substance display field 121 can be deleted by selecting the cancel icon 114. Also, by selecting an add icon (not shown), an input field for any first substance or second substance can be added.

[Calculation process]
Next, the calculation process executed in steps S2 and S4 will be described. In the calculation process, a value _Ok is calculated based on the total value _Tk and the value _Ik according to a predetermined calculation rule _Rk . The calculation rule R and the value I are input in steps S1 and S2. Below, a case where the calculation process is repeated in order from k=n to k=2 will be described.

The user can arbitrarily set the type of calculation for each calculation rule R. In the following, the ratio calculation (calculation rule R _β ) specifies the amount of the first hair coloring agent or the second hair coloring agent at a ratio specified by the input numerical value (numerical value I β ) relative to the total amount of the first hair coloring agent or the second hair coloring agent inputted before the ratio is inputted (total value T _β-1 ), as the amount of the first hair coloring agent or the second hair coloring agent for which _the ratio is inputted (numerical value O _β ). The magnification calculation (calculation rule R _β ) specifies the amount of the first hair coloring agent or the second hair coloring agent obtained by multiplying the total amount of the first hair coloring agent or the second hair coloring agent inputted before the magnification (total value T _β-1 ) by the magnification specified by the input numerical value (numerical value I _β ), as the amount of the first hair coloring agent or the second hair coloring agent for which the magnification is inputted (numerical value O _β ). Whether the inputted numerical value _Iβ is a ratio or a magnification is determined by the calculation rule R selected by the user.

FIG. 4 is a diagram showing a flowchart of the calculation process according to the first embodiment. The flowchart shown in FIG. 4 calculates the numerical values O ₁ to O _n corresponding to the elements E ₁ to E _n based on the calculation rules R ₁ to R _n and the numerical values I ₁ to I _n . In the flowchart shown in FIG. 4, first, the numerical value I _n is calculated based on the calculation rule R _n , the numerical value O _n , and the total value T _n , so that the total value T _n-1 can be calculated from the total value T _n and the numerical value I _n . The numerical value I _n-1 is calculated based on this total value T _n-1 , the calculation rule R _n-1 , and the numerical value O _n-1 . In this way, the numerical value O ₁ is calculated from the corresponding numerical values O _n in order from the element E _n to the element E ₁ .

In the following, for example, a case will be described in which in each of steps S12 to S14, one of the calculation rules for percentage calculation "%", magnification calculation "x", and gram calculation "g" is calculated, and in step S15, numerical values _O2 and _O1 are calculated using the calculation rule for ratio calculation ":".

First, the terminal 10 determines whether or not a calculation rule R _n exists in the group that is the target of the calculation process (step S11). If a calculation rule R _n exists (YES in step S11), the terminal 10 identifies a numerical value O _n from the total value T _n and the numerical value I _n (step S12). The total value T _n may be a predetermined value, or may _{be a value input by the terminal 10. When the total value T n is} input by the terminal 10, the numerical value is input in step S1.

When step S12 is executed, the terminal 10 uses the calculation rule R _n-1 to identify the numerical value O _n-1 from the total value T _{n -1 and the numerical value I n-1} . Similarly, the terminal 10 uses the calculation rules R _n-2 , R _n-3 , ... R ₆ , R ₅ to identify the numerical values O _n-2 , O _n-3 , ... O ₆ , O _5. Then, the terminal 10 uses the calculation rule R ₄ to identify the numerical value O ₄ from the total value T ₄ and the numerical value I ₄ (step S13). Next, the terminal 10 identifies the numerical value O ₃ from the total value T ₃ and the numerical value I ₃ (step S14). The processes of steps S13 and S14 are executed in the same manner as the process of step S12.

Next, the terminal 10 uses the information identified in steps S12 to S14, and the calculation rule R and the numerical value I input in step S1 to identify the amount (numerical value O) of each of the first hair coloring agent and the second hair coloring agent (step S15). In step S15, the terminal 10 identifies numerical value _O2 and numerical value _O1 from the total value _T2 and numerical value _I2 and numerical value _I1 . In step S15, the terminal 10 may identify the ratio of each of the first hair coloring agent and the second hair coloring agent to the total amount of the hair coloring agent and/or the ratio of the amount of the first hair coloring agent and the second hair coloring agent to the total amount of the hair coloring agent.

If the calculation rule R _n does not exist (NO in step S11), the terminal 10 judges whether or not the calculation rule R _n-1 exists in the group that is the target of the calculation process (step S16). If the calculation rule R _n-1 exists (YES in step S16), the terminal 10 identifies the numerical value O _n -1 from the total value T _{n-1 and} the numerical value I n-1. Similarly, the terminal 10 identifies the numerical values O _n-2 , O _n -3, ... O ₆ , O ₅ using the calculation rules R _n-2 , R _n-3 , ... R ₆ , R _5. Then, the processing from step S13 onwards is executed.

On the other hand, if the calculation rule R _n-1 does not exist (NO in step S16), the terminal 10 judges whether or not the calculation rule R _n-2 exists in the group that is the target of the calculation process. If the calculation rule to be judged does not exist, the terminal 10 judges whether or not the calculation rules R _n-2 , R _n-3 , ... R ₅ , R ₄ are included in the group that is the target of the calculation process. Then, the terminal 10 judges whether or not the calculation rule R ₃ exists in the group that is the target of the calculation process (step S17). If the calculation rule R _x to be judged exists, the terminal 10 uses the calculation rules R _x-1 , R _x-2 , ... R ₆ , R ₅ to identify the numerical values O _x-1 , O _x-2 , ... O ₆ , O _5. x is an integer greater than or equal to 5 and less than or equal to n-2.

If the calculation rule _R3 exists (YES in step S17), the process from step S14 onward is executed. On the other hand, if the calculation rule _R3 does not exist (NO in step S17), the terminal 10 judges whether or not the calculation rule _R2 exists in the group that is the target of the calculation process (step S18). If the calculation rule _R2 exists (YES in step S18), the process of step S15 is executed. On the other hand, if the calculation rule _R2 does not exist (NO in step S18), the terminal 10 outputs an error (step S19). Alternatively, if the calculation rule _R2 does not exist (NO in step S18), the calculation process may not be executed. The calculation process is completed by the above processes of steps S11 to S19.

The process of step S12 will be described. In the first embodiment, the total amount of the hair color agent is fixed. As described above, the calculation rule R _n is a ratio calculation, a proportion calculation, a gram calculation, or a magnification calculation.

In the case of percentage calculation, the total value T _n-1 is multiplied by the numerical value I _n (if the numerical value I _n is input as a percentage, the numerical value is divided by 100), and the numerical value is added to the total value T n-1 to obtain the total value T _n -1. From this relationship, the amount of the first hair color agent or the second hair color agent (numerical value O _{n )} in the percentage calculation and the total value T _n-1 are specified. In the case of magnification calculation, the total value T _n-1 is multiplied by the numerical value I _n , and the numerical value is added to the total value T _{n-1 to obtain the total value T n-1 .} From this relationship, the amount of the first hair color agent or the second hair color agent (numerical value O _n ) in the magnification calculation and the total value T _n-1 are specified. In the case of gram calculation, the numerical value I _n and the numerical value O _n are the same. Furthermore, the total value T _n-1 is specified by subtracting the numerical value I _n from the total value T _n .

A specific calculation process will be described by taking the calculation process for the large group of the first substance shown in Fig. 3 as an example. The total amount of the first hair coloring agent and the second hair coloring agent is calculated to be 100g from the total amount display field 101, and the ratio of the first hair coloring agent to the second hair coloring agent is calculated to be 1:1 from the first substance total amount display field 102 and the second substance total amount display field 103. Therefore, the total amount of the first hair coloring agent (total value _T4 ) corresponding to the large group in Fig. 3 is "50g".

3, there are calculation rules _R2 to _R4 in the large group calculation process. The ratio calculation between "1" corresponding to the first substance display field 111a and "2" and "3" corresponding to the first substance display fields 111b and 111c is calculation rule _R2 , the multiplication factor calculation of "4" to "6" corresponding to the first substance display fields 111d to 111f is calculation rule _R3 , and the gram calculation of "7" corresponding to the first substance display field 111g is calculation rule _R4 .

First, the terminal 10 calculates the value _O4 based on the calculation rule _R4 "g (gram calculation)", the total value _T4 "50g", and the value _I4 "5". The value _O4 is "5.0g". The value _O4 is the value in the usage amount display field 113g corresponding to the first substance display field 111g. When the value _O4 is calculated, the total value _T3 of the values _O1 to _O3 , "45g", is obtained.

Next, the terminal 10 calculates the numerical value _O3 based on the calculation rule _R3 "x (multiplication factor calculation)", the total value _T3 "45g", and the numerical value _I3 "2". Since the numerical value _O3 is the numerical value obtained by multiplying the total value _T2 by the numerical value _I3 "2", the numerical value _O3 is "30g". The numerical value _O3 is the sum of the numerical values in the usage amount display columns 113d to 113f corresponding to the first substance display columns 111d to 111f. When the numerical value _O3 is calculated, the sum _T2 of the numerical values _O1 to _O2 , "15g", is obtained.

Next, the terminal 10 calculates the numerical values O1 and O2 based on the calculation rule _R2 ": (ratio calculation)", the total value _T2 "15g", the numerical value _I2 "5", and the numerical value _I1 " ₂ ". Since the numerical values _O1 and _O2 are calculated to be the ratio of _the numerical value _I1 "2" to the numerical value _I2 "5", the numerical values _O1 and _O2 are "4.3g" and "10.7g", respectively. The numerical value _O2 is the sum of the numerical values in the usage amount display fields 113b and 113c corresponding to the first substance display fields 111b and 111c. The numerical value _O1 is the numerical value in the usage amount display field 113a corresponding to the first substance display field 111a. In this way, the terminal 10 can calculate the numerical values _O1 to _O5 .

The terminal 10 also performs calculations for small groups in a similar manner. For example, there are two small groups of the first substance as shown in FIG. 3. As small groups, "2" and "3" corresponding to the first substance display fields 111b and 112c are calculated at a ratio of "3:2" in the ratio calculation. In addition, as small groups different from the small groups, "4" and "5" corresponding to the first substance display fields 111d and 111e are calculated at a ratio of "1:2" in the ratio calculation, and "6" corresponding to the first substance display field 111f is calculated to be "40%" in the percentage calculation.

In the calculation process for the small group corresponding to the first substance display columns 111d-111f, the terminal 10 uses the numerical value O ₃ "30 g" obtained in the calculation for the large group as the total value for the first substance display columns 111d-111f. In the calculation process for the small group corresponding to the first substance display columns 111b and 111c, the terminal 10 uses the numerical value O ₂ "10.7 g" obtained in the calculation for the large group as the total value for the first substance display columns 111b and 111c.

In addition, on the display screen 100, the large group and the small group are displayed as follows. In the input field 112, the right sides of the input field that are on the same straight line indicate that they are in the same group. In addition, the right-most right side of the input field indicates the calculation rule R and numerical value I of the large group.

The order of calculation rules R ₂ , R ₃ , ..., R _n-1 , R _n corresponds to the order displayed from top to bottom in input fields 112 and 122. The minimum value of n in calculation rule R _n is determined according to the number of ratio calculation rules input in input fields 112 and 122. For example, when ratio calculation rules are input for substances corresponding to elements E ₁ to E ₅ , the minimum value of n is 5.

The calculation information regarding the calculation result displayed in step S5 may be stored as history in the terminal 10 or the server device 2. At this time, the calculation information may be stored in association with time information when the calculation information is stored, information about the person whose hair is to be dyed, and/or input user information. The stored calculation information may be displayed in a list on the display screen.

In the above embodiment, the calculation rule R and the numerical value I of the first or second hair coloring agent contained in the hair coloring agent are input to calculate the numerical value O, which is the amount of each of the first or second hair coloring agents. However, the configuration may also be such that the input of the amount of the first or second hair coloring agent is accepted, and the numerical value I of the calculation rule R of the first or second hair coloring agent is calculated based on the input.

In addition, in accepting the input in step S1 and outputting the information in step S5, a process may be performed to set the brightness of the display screen to a predetermined brightness. The predetermined brightness is, for example, the maximum brightness of the terminal 10 or a preset brightness.

The amount determination process and the calculation process may be executed by the server device based on information inputted at the terminal 10. The method of executing the calculation process is not limited to the above. For example, for the ratio calculation of the calculation process, the amount, ratio, or proportion of each of the first hair coloring agent or the second hair coloring agent can be determined from the total amount of the hair coloring agent by setting the amount of either the first hair coloring agent or the second hair coloring agent as a variable.

Regarding the calculation rule R, it may be possible to input gram calculation with calculation rule _R1 , ratio calculation with calculation rule _Rk , and percentage calculation, gram calculation, or magnification calculation with calculation rules _Rk+1 , _Rk+2 , ..., Rn _-1 , _Rn . In this case, k is an integer of 3 or more, and k is equal to or less than n.

In the above, the process of calculating the numerical value O _k according to the total value T _k and the numerical value I _k in accordance with a predetermined calculation rule R _k is repeated in order from k=n until k=2, and the numerical values O ₁ , O ₂ , ..., O _n-1 , O _n are calculated, but the method of executing the calculation process is not limited to this. The calculation process may be such that the process of calculating the numerical value O _k in accordance with a predetermined calculation rule R _k based on the numerical value I _k is repeated in order from k=2 until k=n, and the numerical values O ₁ , O ₂ , ..., O _n-1 , O _n are calculated.

As the calculation rule, a ratio calculation (calculation rule R _α ), a proportion calculation (calculation rule R _β ), a magnification calculation (calculation rule R _β ), or a gram calculation (calculation rule R _γ ) can be applied. The calculation rule R _α calculates numerical values O ₁ , O ₂ , ... O _α-1 , O _α corresponding to the numerical values I ₁ , I ₂ , ... I _α-1 , I α, respectively, based on the ratios of the numerical values I ₁ , I ₂ , ... I _α-1 , I _α . _α is an integer equal to or greater than 2, and α is equal to or less than n. In addition, the calculation rule R _β calculates the numerical value O _β based on the ratio specified by the numerical value I _β to the total value T _δ of the δ numerical values of the numerical values O ₁ , O ₂ , ... O _δ , or calculates the numerical value O β based on the ratio of the numerical value I _β to the total value T _δ of the _δ numerical values of the numerical values O ₁ , O ₂ , ... O _δ and the numerical value O _β . β is an integer of 3 or more, β is n or less, and δ is (β-1) or less. The calculation rule R _γ calculates the numerical value I _γ to be the numerical value O _γ . γ is an integer of 3 or more, and γ is n or less.

In this case, first, the numerical value _O1 is calculated by the ratio calculation. The ratio calculation may be a calculation of the numerical value _O1 and the numerical value _O2 , or may be a calculation of the numerical value _O1 to the numerical value _O3 . In other words, any number of numerical values O can be calculated from the numerical value _O1 by the ratio calculation. For example, when a ratio calculation is performed based on the numerical value _O1 and the numerical value _O2 , the total value _T2 can be calculated. When the calculation rule _R3 is a ratio calculation or a magnification calculation, the numerical value _O3 can be calculated so that the ratio of the numerical value O3 to the total value _T2 of the numerical values _O1 and _O2 is the ratio specified by the numerical value _I3 . Alternatively, when the calculation rule _R3 is a ratio calculation or _a magnification _calculation , the numerical value _O3 can be calculated so that the ratio of _{the numerical value O3 to} the total value (i.e., the total value _T3 ) of the numerical values _O1 and _O2 is the ratio specified by the numerical value _I3 .

The amount determination process and calculation process may be performed for each part of the hair. The parts of the hair will be described later.

Second Embodiment
An outline of the second embodiment of the present invention will be described below. In the following, as the second embodiment of the present invention, a system for specifying the type and amount of a first hair coloring agent (also referred to as a first hair coloring agent) and/or a second hair coloring agent (also referred to as a second hair coloring agent) for dyeing a customer's hair at a store terminal 3 will be described as an example.

[System Configuration]
5 is a block diagram showing the configuration of a system according to the second embodiment. As shown in the figure, the system is composed of at least one computer device. Specifically, the system is composed of an administrator terminal 1, a server device 2, one or more store terminals 3 (3a to 3z), and a communication network 4. The administrator terminal 1, the server device 2, and the store terminal 3 are communicatively connected to each other via the communication network 4. The system may also include a plurality of administrator terminals 1 as the administrator terminal 1 operated by an administrator.

In the system, any one of the administrator terminal 1, the server device 2, and the store terminal 3 can function as an information processing device. When any one of the administrator terminal 1, the server device 2, and the store terminal 3 functions as an information processing device, information is transmitted and received between the administrator terminal 1, the server device 2, and the store terminal 3 as necessary. The system according to the second embodiment may be composed of one computer device (for example, only the store terminal 3) or may be composed of multiple computer devices. The store terminal 3 is an example of a first computer device. The administrator terminal 1 is an example of a second computer device. The server device 2 may function in a distributed manner across multiple computer devices. For example, instead of the server device 2, a distributed ledger technology such as a blockchain may be used.

[Store terminal configuration]
The store terminal 3 is operated by store staff such as hairdressers or assistants, or by individuals. The store terminal 3 may be installed in a store such as a beauty salon or a hair coloring specialty store that performs hair coloring for customers, or may be carried by an individual without being installed in the store. One store may be provided with one store terminal 3, or multiple store terminals may be provided in one store. For example, multiple terminals may be provided in one store, and multiple hairdressers belonging to one store may each use a different terminal.

The administrator terminal 1 and the store terminal 3 are not particularly limited as long as they are computer devices having a display screen and an input section. The administrator terminal 1 and the store terminal 3 may be stationary and installed in a company office or the like, or may be portable and can be carried by the user when traveling. Examples of the administrator terminal 1 and the store terminal 3 include conventional mobile phones, tablet terminals, smartphones, mobile terminals, and desktop and notebook personal computers. The hardware configuration of the administrator terminal 1 and the store terminal 3 can be the hardware configuration of the terminal 10 described in FIG. 1.

[Server Device Configuration]
6 is a block diagram showing a hardware configuration of a server device according to the second embodiment. The server device 2 includes at least a control unit 21, a RAM 22, a storage unit 23, and a communication interface 24, which are connected to each other via an internal bus.

The control unit 21 is composed of a CPU and ROM, and executes the programs stored in the storage unit 23 to control the server device 3. The control unit 21 also has an internal timer that measures time. The RAM 22 is the work area of the control unit 21. The storage unit 23 is a storage area for saving programs and data. In other words, the storage unit 23 functions as a recording medium that stores programs. The control unit 21 reads out the programs and data from the RAM 22, and performs program execution processing based on information received from the manager terminal 1 or the store terminal 3, respectively.

The program may also be stored in a recording medium such as a CD-ROM. In this case, the program stored in the recording medium may be installed in the administrator terminal 1, the server device 2, or the store terminal 3 to execute the specified function. Alternatively, the program may be distributed from a computer device external to the system. In this case, the program distributed from a computer device external to the system may be installed in the administrator terminal 1, the server device 2, or the store terminal 3 to execute the specified function.

[Registration process]
First, the registration process according to the second embodiment will be described. In the registration process according to the second embodiment, the server device 2 stores image information that allows the user to grasp the color and/or brightness of the hair after dyeing with the first hair color agent in association with the color and/or brightness of the hair before dyeing. In the registration process according to the second embodiment, the server device 2 may store image information that allows the user to grasp the color and/or brightness of the hair after dyeing with the first hair color agent in association with the first hair color agent and the color and/or brightness of the hair before dyeing. In addition, in the registration process according to the second embodiment, the server device 2 may store image information that allows the user to grasp the color and/or brightness of the hair after dyeing with the first hair color agent in association with the first hair color agent, the second hair color agent, and the color and/or brightness of the hair before dyeing.

Here, the hair coloring agent (also called hair color agent) refers to a chemical capable of dyeing the hair of a person to be dyed in different colors and/or brightnesses. The hair color agent may include a first hair color agent and a second hair color agent. In the case of a hair coloring method in which an oxidative dye develops color to dye hair in any color, the hair color agent includes a first hair color agent containing an oxidative dye and an alkaline agent, and a second hair color agent containing an oxidative agent. The second hair color agent is a diluent that is mixed with the first hair color when coloring hair. In the second embodiment, a hair coloring method in which an oxidative dye develops color to dye hair in any color is described, but the system according to the second embodiment can be appropriately applied to any known hair coloring method.

The first hair coloring agent is associated with a color and/or brightness. More specifically, the first hair coloring agent is associated with a color and/or brightness of the hair expected after dyeing with the first hair coloring agent. The color and/or brightness associated with the first hair coloring agent is the color and/or brightness of the hair expected after dyeing, and the color and/or brightness of the hair after actually dyeing with the first hair coloring agent will differ depending on the color and/or brightness of the hair before dyeing. Therefore, the color and/or brightness associated with the first hair coloring agent does not necessarily match the color and/or brightness of the hair after dyeing.

The name or type of the first hair coloring agent indicates the color and/or brightness associated with the first hair coloring agent. The name or type of the first hair coloring agent may be a letter, number, or symbol that indicates the color and/or brightness associated with the first hair coloring agent. The name or type of the first hair coloring agent is represented, for example, by an alphabet such as "A" or "B" and a positive integer such as "1" or "2." The alphabet specifies the color, and the positive integer specifies the brightness. As the number increases, the brightness associated with the first hair coloring agent becomes brighter or darker. It can be seen that the first hair coloring agent "A1" and the first hair coloring agent "A2" have the same color but different brightness. Information regarding the first hair coloring agent is stored in the administrator terminal 1, the server device 2, or the store terminal 3.

Hair color is not particularly limited, but examples include natural, ash, wine, red, orange, etc. Hair brightness may be set to multiple levels according to brightness. For example, the brightness of normal black hair may be set to level 4, and the brightness of light blonde hair may be set to level 18, and the brightness level of hair may be determined in stages. In this case, the brightness of hair is classified into 15 levels.

If brightness is classified into 15 levels as described above and red is represented as "R", then the hair color and brightness that is red and the brightest can be represented as "R18", and the hair color and brightness that is red and the darkest can be represented as "R4". As the numbers increase, such as "R4", "R5", and "R6", the hair color becomes brighter among red hair colors. Also, regarding the color and brightness of the first hair coloring agent, the expected hair color after dyeing that is red and the brightest can be represented as "R18", and the expected hair color after dyeing that is red and the darkest can be represented as "R4".

The image information that allows the user to grasp the color and/or brightness of hair may be a color image or an image of a hair bundle. A hair bundle is a bundle of human or horse hair. By displaying image information that allows the user to grasp the color and/or brightness of hair, it becomes easier for the user to visually grasp the content. Note that, below, image information that allows the user to grasp the color and/or brightness of hair may be referred to as hair information.

Hereinafter, the hair coloring agent, the first hair coloring agent, the second hair coloring agent, the hair color, the hair brightness, and the image information that allows the hair color and/or brightness to be grasped have the same meaning not only in the second embodiment but also in the third embodiment.

Figure 7 is a diagram showing a flowchart of the registration process according to the second embodiment. First, the administrator starts an application program downloaded to the administrator terminal 1 and accesses the server device 2 to log in to the system. Alternatively, the administrator may log in to the system by accessing the server device 2 from the administrator terminal 1 via a web browser.

Next, the manager operates the manager terminal 1 to input the color and/or brightness of the hair before dyeing (step S21). The format of the input information is not particularly limited. The input information may be numbers, letters, symbols, or images. The input information may also be a combination of one or more of numbers, letters, symbols, and images. When an image is input, the manager selects an image displayed on the manager terminal 1, and the color and/or brightness of the hair associated with the image is input. In step S21, it may also be input whether the hair before dyeing is gray or colored. Furthermore, if the hair is gray, the store clerk may input the proportion of black hair or gray hair in the entire hair. The color and/or brightness of the hair before dyeing is also called undercolor or undertone.

Next, the administrator operates the administrator terminal 1 to input the types of the first hair coloring agent and the second hair coloring agent to be used for hair dyeing (step S22). The type of the first hair coloring agent or the second hair coloring agent is, for example, the color and/or brightness associated with the first hair coloring agent, the name, concentration, manufacturer, and other information of the first hair coloring agent or the second hair coloring agent. The number of types of the first hair coloring agent and the second hair coloring agent input in step S22 may be one or two or more. In general treatments, about one to three types of first hair coloring agents are mixed, so the number of types of the first hair coloring agents input in step S22 is preferably five or less. This allows frequently used hair dyeing information to be registered.

Next, the administrator operates the administrator terminal 1 to input the proportions of the first hair coloring agent and the second hair coloring agent to be used for hair dyeing (step S23). The proportion of the first hair coloring agent may be input as a percentage for each of the first hair coloring agents input in step S22 so that the entire first hair coloring agent is 100%, or the ratio in the total amount of the entire first hair coloring agent may be input. The proportion of the second hair coloring agent is input in a similar manner. In addition, the respective ratios or proportions of the entire first hair coloring agent and the entire second hair coloring agent in the entire hair coloring agent that is the combination of the first hair coloring agent and the second hair coloring agent may be input.

Next, the administrator operates the administrator terminal 1 to input hair information about the hair after dyeing (step S24). Next, the information input in steps S21 to S24 is sent from the administrator terminal 1 to the server device 2 as hair dye information (step S25). When the server device 2 receives the hair dye information (step S26), the hair dye information is stored and registered in the hair dye information management table (step S27).

The hair dye information includes image information that allows the user to grasp the color and/or brightness of the hair before dyeing, the type and proportion of hair dye, and the color and/or brightness of the hair after washing, which were input in steps S21 to S24. In step S27, the image information (hair information) that allows the user to grasp the color and/or brightness of the hair before dyeing, the type and proportion of hair dye, and the color and/or brightness of the hair after washing, which were input in steps S21 to S24, is associated and registered as one data set. The hair information is stored in association with the color and/or brightness of the hair before dyeing, and the type and proportion of hair dye.

The registration process is completed by executing steps S21 to S27. Note that the processes of steps S21 to S24 may be executed in a different order. Furthermore, the registration process may be executed by only one computer device (e.g., the administrator terminal 1).

Here, the hair information input in step S24 is, for example, image information that allows the color and/or brightness of the hair after dyeing to be grasped. The hair is a strand of hair (hair bundle) of the color and/or brightness input in step S21, to which a hair color agent prepared by mixing the first hair color agent and the second hair color agent of the type input in step S22 in the ratio input in step S23 has been applied, and after a predetermined time has passed, the color agent is washed off and the hair is dried.

In step S24, the administrator may select and input an image stored in the storage unit 13 of the administrator terminal 1, or an image obtained by photographing the hair after dyeing on the spot. In step S24, the administrator may select and input multiple images as one piece of hair information to be associated with the color and/or brightness of the hair before dyeing and the type and proportion of the hair coloring agent. One piece of hair information may include multiple images.

In the system according to the second embodiment, multiple different pieces of image information may be stored in association with one hair after dyeing. Specifically, multiple pieces of image information taken under different conditions of hair after dyeing with a first hair coloring agent are stored in association with the color and/or brightness of the hair before dyeing.

For example, different images may be input as one piece of hair information for two or more different color temperatures and/or two or more different illuminances, and stored in the server device 2. That is, for each of a plurality of color temperatures, image information that allows the color and/or brightness of hair to be recognized under a light source having the color temperature may be stored as hair information in the server device 2. Also, for each of a plurality of illuminances, image information that allows the color and/or brightness of hair to be recognized when light is irradiated to the hair at the illuminance may be stored as hair information in the server device 2. The image information is stored in the server device 2 in association with the color temperature and/or illuminance.

Specifically, images of one dyed hair taken under a total of 12 different conditions, including four color temperatures and three illuminances, are stored in the server device 2. The number of conditions for photographing the hair can be designed as appropriate. For each of the multiple color temperatures, the color and/or brightness of the hair as viewed under a light source having that color temperature may be represented by numbers, letters, and/or symbols, and for each of the multiple illuminances, the color and/or brightness of the hair as viewed when light is irradiated to the hair at that illuminance may be represented by numbers, letters, and/or symbols.

Color temperature is a quantitative numerical representation of the color of light emitted by a light source. The unit is Kelvin (K), and the higher the color temperature, the closer to blue the color is, and the lower the color temperature, the closer to red the color is. Illuminance indicates the degree of brightness of the light that illuminates the surface of an object. The unit is lux (lx). Below, color temperature and illuminance have the same meanings in the third embodiment as well as the second embodiment.

In the system according to the second embodiment, for example, as image information that allows the color and/or brightness of the same hair to be grasped, an image of hair taken under a light source of 2000 K, which has a color temperature similar to that of a sunrise or sunset, and an image of hair taken under a light source of 6500 K, which has a color temperature similar to that of a daylight fluorescent lamp, may be stored in the server device 2. For each different color temperature, multiple images are stored as hair information. By displaying an image according to the stored color temperature, the color and/or brightness of the hair after dyeing according to the color temperature of the space in which the person to be dyed is present can be more specifically imagined.

In addition, in the system according to the second embodiment, for example, as image information that allows one to grasp the color and/or brightness of the same hair, an image of hair taken by irradiating the hair with light at 300 lx, which is the same illuminance as a bright indoor environment, and an image of hair taken by irradiating the hair with light at 100 lx, which is the same illuminance as a dark indoor environment, may be stored in the server device 2. For each different illuminance, multiple images are stored as hair information. By displaying an image according to the stored illuminance, one can more specifically imagine the color and/or brightness of the hair after dyeing according to the illuminance of the space in which the person to be dyed is present.

Figure 8 is a diagram showing a hair dye information management table according to the second embodiment. The hair dye information management table 30 is stored in the storage unit 23 of the server device 2. The hair dye information management table 30 stores post-dye hair information 33 in association with the type and ratio 31 of the first hair coloring agent used in the hair dyeing, and the color and brightness 32 of the hair before dyeing. The post-dye hair information 33 may also store information on the second hair coloring agent and information on the manufacturer of the first hair coloring agent or the second hair coloring agent in association therewith.

In FIG. 8, the color and/or brightness associated with the first hair color agent is stored as the type of the first hair color agent. For the first hair color agent "A1" stored in the hair dye information management table 30, the associated color is "A" and the associated brightness is "1."

8 is a diagram showing the hair dye information management table 30. In the hair dye information management table 30, one image (or identification information for identifying one image) is stored as post-dye hair information 33 in association with the type and ratio 31 of the first hair color agent and the color and brightness 32 of the hair before hair dyeing. Note that the hair dye information management table 30 may store multiple images as post-dye hair information 33. The hair dye information management table 30 stores, as hair information 33, an image of hair captured after applying a first hair color agent corresponding to the type and ratio 31 of the first hair color agent to hair of a color and brightness corresponding to the color and brightness 32 of the hair before hair dyeing (or applying a hair color agent in which a predetermined amount of a second hair color agent is mixed with the first hair color agent), and after a certain period of time has passed, washing off the applied first hair color agent and drying the hair.

For example, in FIG. 8, a hair coloring agent prepared with 100% of the first hair coloring agent "A1" is applied to hair with a "natural" color tone and a brightness level of "4" before dyeing, and the image "image0001" is stored as hair dyeing information that is washed off and dried after a certain period of time has passed. In addition, multiple images may be stored in association with different color temperatures and/or illuminances as hair dyeing information according to the above conditions.

In addition, FIG. 8 shows an example of the hair dye information management table 30 when the hair color before dyeing is "natural," but the server device 2 may be provided with a different hair dye information management table for each hair color before dyeing. For example, a hair dye information management table may be provided for each color, such as natural, ash, wine, red, orange, etc. Also, for example, a hair dye information management table may be provided for each percentage of gray hair (100%, 50%, 10%, 0% (colored hair), etc.).

Also, a different hair dye information management table may be provided for each manufacturer of the first hair coloring agent. Also, a different hair dye information management table may be provided for each type of second hair coloring agent to be mixed with the first hair coloring agent. The type of second hair coloring agent is determined, for example, by the concentration of the components contained in the second hair coloring agent. Specifically, a hair dye information management table for a second hair coloring agent with a concentration of 1.5%, a hair dye information management table for a second hair coloring agent with a concentration of 3%, a hair dye information management table for a second hair coloring agent with a concentration of 6%, etc. may be provided. Also, different hair dye information management tables may be provided depending on whether the first hair coloring agent and the second hair color are fashion dyes or gray hair dyes.

The image corresponding to the hair information stored in the hair dye information management table is an image of a certain amount and length of undyed hair (hair bundle) that has had a certain amount of hair coloring agent applied to it, a certain amount of time has passed, the hair coloring agent has been washed off, and the hair has been dried. In other words, the hair information stored in the hair dye information management table is an image of hair that has been colored under the same conditions.

In addition, in the registration process shown in FIG. 7, the server device 2 may store image information that allows the color and/or brightness of the hair after it has been dyed with the first hair coloring agent to be grasped and information that allows the color and/or brightness of the hair to be specified, in association with the first hair coloring agent and the color and/or brightness of the hair before it has been dyed. In addition, in the registration process shown in FIG. 7, the server device 2 may store image information that allows the color and/or brightness of the hair after it has been dyed with the first hair coloring agent and the color and/or brightness of the hair before it has been dyed, in association with the first hair coloring agent, the second hair coloring agent, and the color and/or brightness of the hair before it has been dyed.

The format of the information that can identify the color and/or brightness of hair is not particularly limited. The information that can identify the color and/or brightness of hair may be numbers, letters, symbols, or images. Furthermore, the information that can identify the color and/or brightness of hair may be a combination of one or more of numbers, letters, symbols, and images.

[Specific Processing]
Next, the specification process of the system according to the second embodiment will be described. The specification process is a process of accepting input of image information that allows the desired color and/or brightness of hair after dyeing to be grasped, and specifying the amount of hair coloring agent to be used in the treatment. The specification process includes a process of displaying image information that allows the color and/or brightness of hair after dyeing with each of a plurality of first hair coloring agents capable of dyeing hair to different colors and/or brightnesses, which corresponds to the input information that allows the color and/or brightness of hair before dyeing to be specified, based on the correspondence relationship between the color and/or brightness of hair before dyeing stored in the server device 2 and the image information. The specification process can be executed after one or more pieces of hair information are registered in the registration process.

Figure 9 is a diagram showing a flowchart of the specific process according to the second embodiment. First, the store clerk starts an application program downloaded to the store terminal 3 and accesses the server device 2 to log in to the system. Alternatively, the store clerk may log in to the system by accessing the server device 2 from the store terminal 3 via a web browser.

Note that a store ID (information assigned to each store and capable of identifying the store) and a password may be registered in the server device 2 for each store, and the store clerk may be able to log in to the system by inputting the store ID and password into the store terminal 3. Alternatively, a user ID (information assigned to each store clerk and capable of identifying the clerk who is the user) and a password may be registered in the server device 2. The user ID may be stored in association with the store ID.

Next, the store clerk operates the store terminal 3 to input the hair dyeing method of the customer who is to have his/her hair dyed (step S31). For example, the hair dyeing method may be selected as "fashion dyeing", which dyes hair a color, or "gray hair dyeing", which dyes gray hair black. The store terminal 3 displays the options "fashion dyeing" and "gray hair dyeing", and the customer can operate the store terminal 3 to select one of the options. If the store clerk selects gray hair dyeing, the store terminal 3 may accept a selection of the proportion of black or gray hair in the hair. In addition, the customer may be able to select the part of the hair to be dyed as "full dyeing", which is the entire hair, "root dyeing", which is the root part of the hair, or "partial dyeing", which is a specified part of the hair.

Next, the store clerk operates the store terminal 3 to input the hair type corresponding to the customer's hair (step S32). A number of hair types are displayed as options on the store terminal 3, and the store clerk can operate the store terminal 3 to select one of the types.

Here, the hair type is used to distinguish the state of the customer's hair to be dyed. The hair to be dyed is divided into one or more regions depending on the part of the hair (whether it is the root part of the hair near the scalp, the center part, the tip, etc.) and its characteristics. For example, it is divided into one or more regions depending on the part of the hair and whether it is dyed (already dyed hair) or undyed (new hair). Therefore, for example, the hair type may be a hair type having a root part of the hair near the scalp and a new hair region, a center part and a dyed hair region, and a tip part and a dyed hair region, or a hair type having a root part of the hair near the scalp and a new hair region, a center part and a new hair region, and a tip part and a dyed hair region. Hereinafter, the hair type has the same meaning not only in the second embodiment but also in the third embodiment.

In the following steps S33 to S36, the store clerk inputs the color and/or brightness of the user's hair before dyeing one area (e.g., the area at the roots near the scalp) and the second hair color agent, and selects the desired state of the hair after dyeing. Because the color and/or brightness of the hair before dyeing, the second hair color agent, and the desired state of the hair after dyeing are input in steps S33 to S36, in step S42, the server device 2 can identify the first hair color agent to be used for one area (e.g., the area at the roots near the scalp).

After inputting the hair type in step S32, the store clerk operates the store terminal 3 to input information that can identify the color and/or brightness of the hair before dyeing near the scalp (step S33). The hair region that corresponds to the color and/or brightness of the hair before dyeing input in step S33 may be the root region near the scalp, or may be one region in the hair type input in step S32 other than the root region near the scalp. The information that can identify the color and/or brightness of the hair is displayed on the display screen as numbers, letters, symbols, and/or images. When an image is selected, the color and/or brightness of the hair associated with the image is input by selecting the image displayed on the store terminal 3. The store clerk can input information that can identify the color and/or brightness of the hair before dyeing by selecting the displayed information.

Next, the store clerk operates the store terminal 3 to input the type or concentration of the second hair color agent (step S34). Specifically, different concentrations of the second hair color agent are displayed on the store terminal 3, and the concentration of the second hair color agent to be used for the treatment is selected. In addition, in step S34, the store clerk may input the type and ratio of the second hair color agent, and the ratio of the first hair color agent to the second hair color agent.

Based on the information entered in steps S33 and S34, the store terminal 3 displays images corresponding to the multiple pieces of hair information (step S35). In step S35, the store terminal 3 displays image information (hair information) that allows the customer to grasp the color and brightness of the hair after it has been dyed with each of the multiple first hair coloring agents capable of dyeing hair to different colors and brightnesses, which corresponds to the information capable of identifying the color and/or brightness of the hair before dyeing entered in step S33, based on the correspondence relationship between the color and/or brightness of the hair before dyeing stored in step S27 and the image information. The color and/or brightness of the first hair coloring agent capable of dyeing hair to different colors and brightnesses refers to the color and/or brightness associated with the first hair coloring agent. The store clerk can find out the customer's desire as to what color to dye the hair by referring to the hair information displayed on the store terminal 3.

The process of step S35 will be described. Specifically, in step S35, the server device 2 identifies a hair dyeing information management table corresponding to the hair dyeing method and the second hair coloring agent based on the hair dyeing method input in step S31 and the type of the second hair coloring agent input in step S34. The server device 2 then refers to the hair dyeing information management table and identifies hair information corresponding to the information capable of identifying the color and/or brightness of the hair before dyeing input in step S33. The identified hair information is displayed on the store terminal 3.

Here, the display screen displayed in step S35 will be described. FIG. 10 is a diagram showing an example of a display screen according to the second embodiment. As shown in FIG. 10, a desired color display area 80 is displayed on a display screen 70. A menu selection field 71, a second hair color agent selection field 72, and a pre-dyeing hair brightness selection field 73 may also be displayed on the display screen 70.

In the desired color display area 80, brightness 81 is displayed vertically, and color 82 is displayed horizontally. In addition, in the desired color display area 80, hair information 83 corresponding to brightness 81 and color 82 is displayed in a matrix. Brightness 81 is the brightness associated with the first hair color agent, and color 82 is the color associated with the first hair color agent. The hair information 83 corresponds to image information of hair after dyeing in which a hair color agent prepared with the first hair color agent corresponding to brightness 81 and color 82 and the second hair color agent input in step S34 is applied to the hair input in step S33. Note that the first hair color agent stored in association with the hair information 83 displayed in the desired color display area 80 may be one type, or may be two or more types, but is preferably one type.

In the desired color display area 80, images corresponding to hair information having the same color associated with the first hair color agent but different brightness associated with the first hair color agent are displayed side by side. Specifically, the images are arranged so that the brightness associated with the first hair color agent becomes darker from the images displayed at the top to the images displayed at the bottom of the display screen 70. In addition, in the desired color display area 80, images corresponding to hair information having the same brightness associated with the first hair color agent but different color associated with the first hair color agent are displayed side by side. Specifically, the images are arranged so that the color associated with the first hair color agent becomes more bluish to more reddish from the images displayed at the left to the right of the display screen 70.

Alternatively, in the desired color display area 80, images corresponding to hair information having the same color associated with the first hair color agent but different brightness associated with the first hair color agent may be displayed side by side. Also, in the desired color display area 80, images corresponding to hair information having the same brightness associated with the first hair color agent but different color associated with the first hair color agent may be displayed side by side up and down.

By selecting a menu from the menu selection field 71, the hair information 83 displayed in the desired color display area 80 can be changed. A menu of hair information 83 displayed in the desired color display area 80 is stored in the server device 2. The menu includes multiple pieces of hair information. The multiple pieces of hair information are, for example, all hair information stored in the server device 2, specific hair information selected by operating the administrator terminal 1 or the store terminal 3, hair information stored in association with a hair color agent of a specific manufacturer, etc. The hair information selected by operating the administrator terminal 1 or the store terminal 3 is not particularly limited, and can be, for example, hair information corresponding to a first hair color agent or a second hair color agent prepared in the store.

The second hair color displayed in the second hair color selection field 72 corresponds to the second hair color input in step S34. By selecting the type or concentration of the second hair color in the second hair color selection field 72, the hair information 83 displayed in the desired color display area 80 can be changed to hair information corresponding to the selected type or concentration of the second hair color. The undyed hair brightness displayed in the undyed hair brightness selection field 73 corresponds to the undyed hair brightness input in step S33. By selecting the undyed hair brightness selection field 73, the hair information 83 displayed in the desired color display area 80 can be changed to hair information corresponding to the selected hair brightness. The undyed hair brightness selection field 73 may be configured to allow input of hair color.

The hair information 83 displayed in the desired color display area 80 may be changed in color temperature and/or illuminance at which the displayed image was captured. The color temperature and/or illuminance of the hair information 83 displayed in the desired color display area 80 may be preset. In the second embodiment, different images for two or more different color temperatures and/or illuminances are registered in the server device 2 as one piece of hair information, and when the color and/or brightness of the hair before dyeing, the type and ratio of the first hair color agent and/or the second hair color agent, and the color temperature or illuminance are input by operating the administrator terminal 1 or the store terminal 3, image information that can grasp the color and/or brightness of the hair after dyeing, captured at the corresponding color temperature or illuminance, is displayed.

Although not shown, icons for displaying images of hair viewed under light sources with different color temperatures may be displayed on the display screen 70, and by selecting the icon, images of hair viewed under light sources with different color temperatures may be displayed. For example, by selecting an icon showing a morning state, an image of hair taken under a light source with a color temperature equivalent to that of morning may be displayed. Alternatively, for example, by selecting an icon showing an evening state, an image of hair taken under a light source with a color temperature equivalent to that of evening may be displayed. Each icon corresponds to a color temperature associated with the hair information. By selecting a color temperature on the store terminal 3 or the administrator terminal 1, hair information corresponding to that color temperature is displayed.

Although not shown, icons for displaying images of hair visible when light is irradiated to the hair at different illuminances may be displayed on the display screen 70, and by selecting the icon, images of hair visible when light is irradiated to the hair at different illuminances may be displayed. For example, by selecting an icon indicating an outdoor condition, an image of hair photographed by irradiating the hair with light at an illuminance equivalent to that outdoors may be displayed. Alternatively, by selecting an icon indicating an indoor condition, an image of hair photographed by irradiating the hair with light at an illuminance equivalent to that indoors may be displayed. Each icon corresponds to an illuminance associated with the hair information. By selecting an illuminance on the store terminal 3 or the manager terminal 1, hair information corresponding to the illuminance is displayed.

If a selection of the proportion of black or white hair in the hair is accepted in step S31, then in step S35 the store terminal 3 can display different image information (hair information) depending on the proportion of black or white hair in the accepted selection. In step S35, the server device 2 can identify a hair dye information management table corresponding to the proportion of black or white hair in the accepted selection, and identify an image corresponding to the specified hair information.

The store clerk operates the store terminal 3 to select one of the hair information items displayed by the process of step S35 (step S36). In step S36, the desired color and/or brightness of the hair after dyeing (also referred to as the desired state of the hair after dyeing) is input by selecting one image corresponding to the hair information. In step S36, the first hair coloring agent or the desired color and/or brightness of the hair may be input instead of selecting the hair information. The desired color and/or brightness of the hair after dyeing may be input by inputting numbers, letters, symbols, etc., or by selecting an image. The server device 2 can specify the first hair coloring agent to be used in one area (e.g., the area at the root near the scalp) in step S42 described below based on the hair information selected in step S36, the color and/or brightness of the hair before dyeing input in step S33, and the second hair coloring agent input in step S34.

In the following steps S37 to S41, the color and/or brightness of the hair before dyeing and the second hair coloring agent are input for each of the areas (e.g., the central area of the hair, the area of the hair tips, etc.) different from the area 1 input in steps S33 to S36, and the desired hair condition after dyeing for the area different from the area 1 input in steps S33 to S36 is selected. Because the color and/or brightness of the hair before dyeing, the second hair coloring agent, and the desired hair condition after dyeing are input in steps S37 to S41, in step S42, the server device 2 can identify the first hair coloring agent to be used for the area different from the area 1 input in steps S33 to S36.

After selecting hair information in step S36, the store clerk operates the store terminal 3 to input information for one area of the hair type selected in step S32 that can identify the color and/or brightness of the customer's undyed hair that corresponds to that area (step S37). In addition, in step S37, the store clerk inputs the customer's hair length that corresponds to that area along with the color and/or brightness of the undyed hair. Note that the one area input in step S37 is a different area from the area input in step S33.

Next, the store clerk operates the store terminal 3 to input the type or concentration of the second hair color agent (step S38). Step S38 is the same process as step S34. If the information input in step S34 is used, the process of step S38 can be omitted. The information input in steps S37 and S38 is sent to the server device 2, and the server device 2 identifies multiple predicted post-dye hair information items according to the sent information (step S39).

The predicted hair information after dyeing refers to image information that allows one to grasp the predicted color and/or brightness of the hair when a specific hair coloring agent is applied to the customer's undyed hair, rinsed off after a specific time has passed, and then dried.

The process of step S39 will be described. The process of step S39 includes the processes of steps S39-1 to S39-4. The server device 2 identifies a hair dye information management table to be referenced when identifying the expected hair information (step S39-1). For example, a hair dye information management table corresponding to the manufacturer, the hair dye method, the hair color, or the second hair color is identified from the manufacturer of the first hair coloring agent input, the hair dyeing method input in step S31, the hair color information input in step S37, or the information of the second hair coloring agent input in step S38. The server device 2 can refer to the identified hair dye information management table and identify multiple first hair coloring agents capable of dyeing hair to a specified hair color and multiple pieces of hair information stored in association with the color and/or brightness of the hair before dyeing input in step S37.

The specified hair color is the color of the first hair coloring agent stored in association with the hair information selected in step S36. The specified hair color is also the hair color desired by the user (also called the customer) after hair dyeing. The server device 2 refers to the hair dye information management table identified in step S35 and identifies the first hair coloring agent stored in association with the hair information selected in step S36 (step S39-2). In step S39-2, the server device 2 may identify the first hair coloring agent input in step S36 or a first hair coloring agent corresponding to the desired hair color and/or brightness.

Next, based on the first hair color agent identified in step S39-2, the server device 2 identifies multiple first hair color agents that have the same associated color as the first hair color agent but different associated brightness (step S39-3). Then, the server device 2 refers to the hair dye information management table identified in step S39-1 and identifies multiple pieces of hair information stored in association with each of the first hair color agents identified in step S39-3 and the color and/or brightness of the hair before dyeing input in step S37 (step S39-4).

In step S39-3, the method of identifying multiple first hair color agents is not particularly limited. For example, based on the hair information selected in step S36, the server device 2 identifies a first hair color agent having the same color and brightness as the first hair color agent identified in step S39-2, and then identifies a first hair color agent having the same color as the identified first hair color agent but a different brightness. Multiple first hair color agents may be identified as first hair color agents having the same color as the identified first hair color agent but a different brightness.

Specifically, if the brightness level of the first hair color agent identified in step S39-2 is "5" based on the hair information selected in step S36, a first hair color agent with the same color and brightness level "5" is identified, and also a first hair color agent with the same color but lower brightness levels "4" and "3" and a higher brightness level "6" and "7" can be identified.

In step S39-3, the server device 2 may identify a first hair color agent whose associated color has a predetermined relationship with a predetermined color. A first hair color agent whose associated color has a predetermined relationship with a predetermined color is, for example, a first hair color agent whose associated color is an adjacent color on the color wheel.

In addition, in step S39-3, the server device 2 may identify a first hair color agent whose associated color is a predetermined color and whose associated brightness is within a predetermined range. A first hair color agent whose associated brightness is within a predetermined range is, for example, a first hair color agent whose level difference is within a predetermined range (e.g., ±2 levels) from the brightness level associated with the first hair color agent identified from the hair information.

In addition, in step S39-3, the server device 2 may identify a first hair coloring agent that contains a predetermined percentage or more of the first hair coloring agent stored in association with the hair information selected in step S36. Specifically, when two or more types of first hair coloring agents are mixed, the server device 2 may identify a first hair coloring agent whose percentage of the identified first hair coloring agent in the total amount of the first hair coloring agent is a predetermined percentage or more (e.g., 30% or more), or a first hair coloring agent whose percentage of the identified first hair coloring agent in the total amount of the first hair coloring agent is the largest compared to other first hair coloring agents.

In addition, in step S39-3, the server device 2 may identify hair coloring agents made by the same manufacturer as the first hair coloring agent stored in association with the hair information selected in step S36, or hair coloring agents that are in stock at the store.

In step S39-2, if a first hair coloring agent was input in step S36, the server device 2 identifies the first hair coloring agent. Also, in step S39-2, if a desired hair color and/or brightness was input in step S36, the server device 2 identifies the first hair coloring agent associated with the color and/or brightness.

The hair dye information management table identified in step S39-1 may be within a range that has a predetermined correlation with the type or concentration of the second hair color agent entered in step S38. The range that has the predetermined correlation may be, for example, a concentration range of 1% or less.

In step S39, the server device 2 may identify image information that allows the user to grasp the color and/or brightness of the hair after dyeing that has a predetermined relationship with the input desired color and/or brightness of the hair after dyeing. In other words, the process of step S39 can also be performed as follows. Note that explanations of similar processes may be omitted.

For example, the server device 2 can refer to the identified hair dye information management table and identify hair information that has a predetermined relationship with the hair information input in step S36. Hair information that has a predetermined relationship is, for example, image information obtained by converting the image information (hair information) input in step S36 and the hair information in the hair dye information management table into RGB values, and the image information is the same or has an error within a predetermined range. In addition, if the hair information stored in the hair dye information management table is stored as a numerical value indicating the color and/or brightness of the hair, hair information that has a predetermined relationship may be hair information that is the same or has an error within a predetermined range with the numerical value indicating the input desired hair color and/or brightness.

The post-dye hair information identified in step S30 is sent to the store terminal 3, and multiple post-dye hair information items are displayed on the store terminal 3 (step S40).

In steps S39 and S40, based on the correspondence between the color and/or brightness of the hair before dyeing stored in step S27 and the image information, image information (hair information) that corresponds to the information that can specify the color and/or brightness of the hair before dyeing input in step S37 and allows the brightness of the hair after dyeing with each of the multiple first hair coloring agents that can dye the hair to a specified hair color is displayed. Alternatively, in steps S39 and S40, based on the correspondence between the color and/or brightness of the hair before dyeing stored in step S27 and the image information, image information that corresponds to the information that can specify the color and/or brightness of the hair before dyeing input in step S37 and allows the color and brightness of the hair after dyeing with each of the multiple first hair coloring agents that can dye the hair to a specified hair color is displayed.

The hair information displayed in step S40 may be all of the hair information identified in step S39, or only a portion of the hair information. For example, hair information stored in association with a first hair coloring agent that is in large stock at the store or a first hair coloring agent that has a short expiration date may be preferentially displayed. Hair information stored in association with a small number of types of first hair coloring agents may also be preferentially displayed. Alternatively, when hair information associated with a hair coloring agent that contains two or more types of first hair coloring agents is identified, the hair information may not be displayed in step S40, and may be displayed in a separate window by inputting an operation to the store terminal 3. The store clerk can check this as hair information of variations.

Here, the display screen displayed on the store terminal 3 in step S40 will be described. In step S40, the server device 2 may control the display to display the hair information selected in step S36 and the hair information specified in step S39. FIG. 11 is a diagram showing an example of a display screen according to the second embodiment.

As shown in FIG. 11, the display screen 40 displays the application result 41 and the desired color 42. The application result 41 is image information that allows the user to grasp the color and/or brightness of the hair after dyeing specified in step S39. The desired color 42 is image information that allows the user to grasp the color and/or brightness of the hair after dyeing desired by the user input in step S36. The color and/or brightness of the hair before dyeing associated with the desired color 42 may be the same as or different from the color and/or brightness of the hair before dyeing input in step S37.

The input information 43 entered in steps S37 and S38 may be displayed on the display screen 40. The display screen 40 displays "2nd agent 3%" and "Natural level 6" as input information 43, and also displays "2 Application color selection" since it is a display screen for inputting information related to "area 2" included in the hair pattern. For example, if it is a display screen for inputting information related to "area 3", "3 Application color selection", the concentration of the second hair color agent, and the color and brightness of the hair before dyeing may be displayed. The display screen 40 is different for each area included in the hair pattern for which input is made.

In addition, multiple application results 41 (41a to 41d) are displayed next to the desired color 42. Since multiple application results 41 (41a to 41d) are displayed next to the desired color 42, it is easy to compare colors, and the store clerk can select an application result 41 with a color and/or brightness close to the desired color 42. In addition, for example, although not shown, the application results 41 can display application results 41 other than the application results 41a to 41d. Specifically, by scrolling or swiping the display screen 40 horizontally, the display position of the application results 41a to 41d may move, and application results 41c to 41f may be displayed from the left. It is preferable that the display position of the desired color 42 is fixed.

The manner in which the multiple application results 41 are displayed alongside the desired color 42 is not limited to the manner shown in FIG. 11 and can be set as appropriate. For example, one application result 41 and the desired color 42 may be displayed large, and by selecting, swiping, scrolling, etc. on the screen, the application result 41 may be switched to a different application result 41 and the different application result 41 and the desired color 42 may be displayed large. Also, for example, the desired color 42 may be displayed alongside the multiple application results 41 above or below them.

In addition, a supplementary explanation may be displayed for each application result 41. The supplementary explanation may display information about the first hair coloring agent stored in association with the application result 41. For example, it may be displayed that the application result 41a is stored in association with the first hair coloring agent "N1". In addition, the supplementary explanation may display which application result 41 is recommended to provide the customer with hair coloring in the desired color 42. In FIG. 11, it is displayed that the application result 41d is recommended. The recommendation may be displayed for the application result 41 that is closest in color and/or brightness to the desired color 42 among the displayed application results 41.

It is preferable that the desired color 42 and/or the application result 41 are a color image or an image of a hair bundle. When the enlargement icon 44 of the application result 41a displayed in FIG. 11 is selected, the image of the hair bundle may be displayed enlarged in a separate window. In addition, the application result 41 may display a color image obtained by converting the image of the specified hair bundle into RGB values.

Furthermore, the server device 2 may be controlled to display, as the desired color 42 and/or application result 41, information that allows the user to grasp the color and/or brightness of the hair as viewed under a light source having the desired color temperature for each of a plurality of color temperatures, or may be controlled to display, as the desired color 42 and/or application result 41, information that allows the user to grasp the color and/or brightness of the hair as viewed when light is irradiated to the hair at each of a plurality of illuminances.

Although not shown, icons for displaying images of hair viewed under light sources with different color temperatures may be displayed on the display screen 40, and by selecting the icon, an image of hair viewed under a light source with a different color temperature may be displayed. For example, by selecting an icon showing a morning state, an image of hair viewed under a light source with a color temperature equivalent to that of morning may be displayed. Alternatively, for example, by selecting an icon showing an evening state, an image of hair viewed under a light source with a color temperature equivalent to that of evening may be displayed. By selecting a color temperature on the store terminal 3 or the administrator terminal 1, hair information corresponding to that color temperature is displayed.

Although not shown, icons for displaying images of hair visible when light is irradiated to the hair at different illuminances may be displayed on the display screen 40, and by selecting the icon, images of hair visible when light is irradiated to the hair at different illuminances may be displayed. For example, by selecting an icon indicating an outdoor condition, an image of hair visible when light is irradiated to the hair at an illuminance equivalent to that outdoors may be displayed. Alternatively, for example, by selecting an icon indicating an indoor condition, an image of hair visible when light is irradiated to the hair at an illuminance equivalent to that indoors may be displayed. By selecting an illuminance on the store terminal 3 or the administrator terminal 1, hair information corresponding to the illuminance is displayed.

Returning to the description of the flow chart of the identification process in FIG. 9, the store clerk operates the store terminal 3 to select one piece of hair information from the multiple pieces of hair information displayed in step S40 (step S41). The process in step S41 accepts the selection of image information in a state in which image information that allows the user to grasp the color and/or brightness of the hair after dyeing with each of the multiple first hair coloring agents is displayed in step S40. Alternatively, in step S41, the store clerk may input the first hair coloring agent or the color and/or brightness of the hair after dyeing as desired by the user, instead of an image corresponding to the hair information. When the first hair coloring agent or the color and/or brightness of the hair after dyeing as desired by the user is displayed on the store terminal 3, it is preferable that each of the application results 41 in FIG. 11 displays information on the first hair coloring agent or information that allows the user to identify the color and/or brightness of the hair corresponding to the application result.

The processes of steps S37 to S41 are executed for each region included in the hair pattern input in step S32. Therefore, the processes of steps S37 to S41 are repeatedly executed until input is completed for all regions. When the process of step S41 is executed for all regions included in the hair pattern, the repeated processes of steps S37 to S41 are terminated. For the region input in step S33, the store clerk may input the length of the hair before dyeing at any timing before the process of step S33 or step S42. Alternatively, the region and length input in step S33 may be stored in advance in the server device 2.

When the repeated process from steps S37 to S41 is completed, the server device 2 identifies the type and ratio of the first hair color agent and the second hair color agent (step S42). In addition, if the hair length corresponding to the area input in step S33 and the hair length were input in step S37, the amount of the first hair color agent or the second hair color agent for each area may be identified in step S42. The amount of the first hair color agent or the second hair color agent is identified based on an application amount calculation table that associates the hair length with the amount of the first hair color agent or the second hair color agent and is stored.

When step S42 is executed, the type, ratio, and amount of the identified first hair color agent and second hair color agent are displayed on the store terminal 3 for each area included in the hair type (step S43).

The process of step S42 will now be described. In step S42, the types, ratios, and amounts of the first hair coloring agent and the second hair coloring agent are identified for the areas included in the hair pattern input in step S33 and for each of the areas included in the hair patterns input in steps S37 to S41. In step S42, it is possible to identify multiple first hair coloring agents to be used for multiple different parts of the hair. The first hair coloring agent and the second hair coloring agent identified in step S42 are the first hair coloring agent and the second hair coloring agent to be used for hair coloring.

The server device 2 identifies the first hair coloring agent selected in step S36 or S41, the first hair coloring agent corresponding to the color and/or brightness of the hair after dyeing selected in step S36 or S41, or the first hair coloring agent corresponding to the image information selected in step S36 or S41 as the first hair coloring agent to be used.

When the server device 2 identifies the first hair coloring agent corresponding to the color and/or brightness of the hair after dyeing, the selection of which was accepted in step S41, as the first hair coloring agent to be used, for example, for one area included in the hair pattern, the server device 2 can refer to the hair dye information management table identified in step S39-1 and identify the first hair coloring agent stored in association with information that can identify the color and/or brightness of the hair after dyeing, the selection of which was accepted in step S41. At this time, multiple first hair coloring agents may be identified. The identified first hair coloring agents may be displayed on the store terminal 3, and the store clerk may select one first hair coloring agent as the first hair coloring agent to be used.

When the server device 2 identifies the first hair color agent corresponding to the color and/or brightness of the dyed hair selected in step S36 as the first hair color agent to be used, for example, for one area included in the hair type, the server device 2 can refer to the hair dye information management table corresponding to the hair information identified in step S35 and identify the first hair color agent stored in association with information that can identify the color and/or brightness of the dyed hair selected in step S33.

When the server device 2 identifies the first hair coloring agent corresponding to the image information selected and accepted in step S41 as the first hair coloring agent to be used, for one area included in the hair pattern, the server device 2 can refer to the hair dye information management table identified in step S39-1 and identify the first hair coloring agent stored in association with the image information (hair information) selected and accepted in step S41.

When the server device 2 identifies the first hair color agent corresponding to the image information selected and accepted in step S36 as the first hair color agent to be used, for one area included in the hair pattern, the server device 2 can refer to the hair dye information management table identified in step S35 and identify the first hair color agent stored in association with the image information (hair information) selected and accepted in step S36.

In the following steps S44 to S47, it is possible to change the type and ratio of the hair coloring agent displayed in step S43, and fine-tune the hair coloring agent used in the treatment, such as adding a different color or changing the brightness. In addition, the condition of the hair after dyeing with the fine-tuned hair coloring agent can be displayed. Since the color and/or brightness of the hair before dyeing and the second hair coloring agent are input in steps S33 and S34, steps S37 and S38, in step S45, the server device 2 can identify the condition of the hair after dyeing with the fine-tuned hair coloring agent.

When the types and proportions of hair coloring agents are displayed in step S43, the store clerk operates the store terminal 3 to execute an amount specification process that specifies the amounts of the first hair coloring agent and the second hair coloring agent to be used in the actual treatment for one area included in the hair pattern (step S44). The amount specification process can be the amount specification process in the first or third embodiment.

Specifically, when the amount determination process in the first embodiment is used, the type and amount of the first hair coloring agent and the second hair coloring agent determined in step S42 are displayed on the display screen 100 in FIG. 3. For example, the type of the first hair coloring agent is displayed in the first substance display field 111, and the amount of the first hair coloring agent is displayed in the usage amount display field 113. The user can add, delete, change, etc. the element E, the calculation rule R, and the numerical value I, as well as the ratio or amount of the first hair coloring agent and the second hair coloring agent displayed in the first substance total amount display field 102 and the second substance total amount display field 103.

Next, the server device 2 refers to the hair dye information management table and identifies hair information after dyeing that is expected to be done using the identified hair coloring agents based on the types and ratios of the first and second hair coloring agents identified by the amount identification process and the information entered in steps S33 and S34, or S37 and S38 (step S45). The processing method of step S45 will be described later.

The hair information after dyeing that is predicted using the identified hair coloring agent is displayed on the store terminal 3 (step S46). If the store clerk determines that there is no problem with the hair color and/or brightness of the displayed hair information, the store clerk operates the store terminal 3 to determine that the hair coloring agent identified in step S44 is the hair coloring agent to be used for treating one area included in the hair pattern (step S47). On the other hand, if the ratio and/or amount of the first hair coloring agent or the second hair coloring agent is to be further adjusted to change the hair color and/or brightness of the hair information displayed in step S46, the processing from steps S44 to S46 is executed again.

When the process has been repeated for all areas included in the hair pattern, the store clerk operates the store terminal 3, and the types and ratios of the first and second hair coloring agents determined in step S47 are stored and registered in the server device 2 as the hair coloring agents to be used in the customer's treatment (step S48). Customer information such as the customer's name, the condition of the customer's hair before dyeing, the condition of the customer's hair after dyeing, and the date of dyeing may be stored and registered in association with the hair coloring agents to be used in the customer's treatment.

When the types and ratios of the first and second hair coloring agents are registered in step S48, information regarding the types and ratios of the first and second hair coloring agents is notified from the server device 2 or the store terminal 3 to the manager terminal 1 (step S49). After steps S31 to S49, the identification process is completed.

The identification process may be executed by only one computer device. The processes of steps S31 to S34 and steps S37 to S38 may be executed in a reverse order. The process of step S34 or S38 may be omitted. In this case, it is preferable that the information on the second hair color agent is set in advance in the server device 2. The processes of steps S45, S46, or S49 may be omitted. The processes of steps S36 and S41 may be executed by the customer himself operating the store terminal 3.

Before step S35, the manufacturer of the first or second hair coloring agent may be displayed, and a specific manufacturer to be used for the treatment may be input. In this case, in steps S35 and S41, a color image or a hair bundle image corresponding to the hair information stored in association with the hair coloring agent of the input manufacturer is displayed.

The process of step S45 will be described. The server device 2 refers to the hair dye information management table and identifies the corresponding post-dye hair information according to the type and ratio of the first hair color agent and the second hair color agent identified in step S44 and the color and/or brightness of the hair before dyeing input in step S37.

The post-dye hair information to be identified may be determined not only from the type and ratio of the first hair coloring agent and the second hair coloring agent that are the same as the type and ratio of the first hair coloring agent and the second hair coloring agent identified in step S44, but also from the type and ratio of the first hair coloring agent and the second hair coloring agent that have a predetermined correlation with the type and ratio of the first hair coloring agent and the second hair coloring agent identified in step S44.

The type of first hair coloring agent having a predetermined correlation with the type of the first hair coloring agent may refer to, for example, a type of first hair coloring agent whose color and/or brightness associated with the first hair coloring agent is within a predetermined range. Furthermore, the ratio of the first hair coloring agent and the second hair coloring agent having a predetermined correlation with the displayed ratio of the first hair coloring agent and the second hair coloring agent may refer to, for example, a ratio of the first hair coloring agent and the second hair coloring agent whose ratio or ratio is within a predetermined range.

The ratio of the first hair coloring agent and the second hair coloring agent, in which the ratio or ratio of the first hair coloring agent and the second hair coloring agent is within a predetermined range, will be described. For example, when three types of first hair coloring agents are input in step S44 and the respective ratios are 12%, 37%, and 51%, in step S45, the server device 2 can extract hair information with the respective ratios rounded off to the nearest 10%, 40%, and 50%. Also, for example, when three types of first hair coloring agents are input in step S44 and the ratio is 1.7:2:3.1, in step S45, the server device 2 can extract hair information with the respective ratios rounded off to the nearest 2:2:3.

For example, when the types of first hair coloring agents input in step S44 are "A1," "A2," and "B5," in step S45, the server device 2 can extract hair information of the types of first hair coloring agents that are different from each other. It is preferable that the different types of first hair coloring agents are first hair coloring agents whose color and/or brightness have a predetermined correlation.

In addition, if hair dye information is identified based on information that is not the same as the type and ratio of the first and second hair coloring agents identified in step S44, it is preferable that this be displayed in a manner that makes it clear in step S46. In addition, the type and ratio of the identified first and second hair coloring agents may be displayed.

If the hair dye information management table does not store hair dye information in association with the type and ratio of the first hair color agent and the second hair color agent identified in step S44 and the color and/or brightness of the hair before dyeing input in step S37, the expected hair dye information cannot be identified in step S45. In that case, a process may be executed in which the server device 2 notifies the store terminal 3 and the administrator terminal 1 of missing information indicating that the hair dye information cannot be identified.

The process of step S49 will be described. In step S49, the input desired hair color and/or brightness after hair dyeing, as well as the customer's hair color and/or brightness before hair dyeing may be notified. The process of step S49 may be executed each time a hair coloring agent is registered, when a predetermined number of hair coloring agents are registered, or when a predetermined period of time has passed, such as once a month. When hair information corresponding to the types and ratios of the first hair coloring agent and the second hair coloring agent included in the notification is not registered in the hair dye information management table, the notification of step S49 transmits missing information indicating that image information capable of grasping the color and/or brightness of the hair after hair dyeing is not stored. The missing information may include information prompting the administrator to register image information capable of grasping the color and/or brightness of the hair after hair dyeing.

In other words, the process of step S49 can be said to be a process of sending missing information to the manager terminal 1 when image information that allows the color and/or brightness of the hair after dyeing is not stored for the hair color agent input at the store terminal 3. The manager can check the missing information and execute the above-mentioned registration process.

The shortage information may also include information regarding the number of times notifications have been sent regarding the types and ratios of the first and second hair coloring agents. The administrator may execute the above-mentioned registration process for the types and ratios of the first and second hair coloring agents that have been notified a predetermined number of times or more. In the registration process, the server device 2 stores image information that allows the color and/or brightness of the hair after dyeing to be understood in association with the first hair coloring agent, the second hair coloring agent, and the color and/or brightness of the hair before dyeing that correspond to the shortage information transmitted in step S49. The process of step S49 corresponds to step S51 described below, and the above registration process corresponds to the processes of steps S53 to S54.

The registered hair information may be displayed in the new identification process in the process of step S35, S41 or S46. In other words, the server device 2 can refer to the stored hair dye information management table to identify image information that allows the color and/or brightness of the dyed hair to be grasped, which corresponds to the hair coloring agent for dyeing the hair to the desired color and/or brightness, inputted in the administrator terminal 1 or another store terminal 3. Furthermore, it can identify image information that allows the color and/or brightness of the dyed hair to be grasped, which corresponds to the hair coloring agent having a predetermined correlation with the hair coloring agent for dyeing the hair to the desired color and/or brightness, inputted in the administrator terminal 1 or another store terminal 3. The identification process can be executed in the same manner as the processes of steps S31 to S49.

In the above specific process, we have described a mode in which the entire customer's hair is colored uniformly, but this is not limited to this, and coloring in which different parts of the hair are colored differently can also be applied. Coloring in which different parts of the hair are colored differently means, for example, coloring a single hair with different colors, such as coloring the scalp to center and the ends of the hair, or coloring different parts of the hair that grow there, such as coloring the front hair and other parts, or coloring the area around the ears and other parts, or a combination of these.

In the case of coloring in which the color of a single hair is different, in steps S36 and S41, hair information corresponding to the desired color and/or brightness of the hair after dyeing is selected. In the case of coloring in which the color is different for each part of the hair growing, in step S31, the part for which the color and/or brightness is desired for each desired color and/or brightness of the hair after dyeing may be input. Next, the processing of steps S32 to S47 is repeatedly executed for each input part. Then, steps S48 and S49 are executed, and the identification processing ends. For example, in the case of coloring in which the color of the front hair and the other parts are different, in step S31, the front hair and the other parts are input as the parts of the hair to be dyed. Then, the processing of steps S32 to S47 is executed for the front hair part and the other parts, respectively.

[Notification Processing]
The notification process will be described. Fig. 12 is a diagram showing a flowchart of the notification process according to the second embodiment. If the hair information after dyeing cannot be specified in step S45, step S46 is not executed, and the server device 2 transmits a message to the store terminal 3 and the manager terminal 1 indicating that the hair information after dyeing cannot be specified (missing information) (step S51). The store terminal 3 and the manager terminal 1 receive the missing information (steps S52 and S53).

In steps S51 and S53, in addition to the missing information, information is sent and received regarding the type and ratio of the first and second hair coloring agents identified in step S44, and the color and/or brightness of the hair before dyeing that was entered in step S33 or S37. The administrator operates the administrator terminal 1 to confirm the type and ratio of the first and second hair coloring agents, and the color and/or brightness of the hair before dyeing. Then, the administrator executes the above-mentioned registration process for the information (step S54).

In step S54, a hair coloring agent prepared with the same types and ratios of the first and second hair coloring agents as the received first and second hair coloring agents may be applied to undyed hair of the same color and/or brightness as the received color and/or brightness, and image information that allows the color and/or brightness of the hair after a predetermined time has passed may be registered.

Alternatively, the above-mentioned registration process may be performed for the type and ratio of the first hair coloring agent and the second hair coloring agent, which allows the hair information after dyeing to be specified in S39 or S45 from the type and ratio of the first hair coloring agent and the second hair coloring agent received in step S53, and the color and/or brightness of the hair before dyeing. Specifically, the above-mentioned registration process may be performed for the type and ratio of the first hair coloring agent and the second hair coloring agent that have a predetermined correlation with the type and ratio of the first hair coloring agent and the second hair coloring agent received. In step S51, information regarding the type and ratio of the first hair coloring agent and the second hair coloring agent that have a predetermined correlation with the type and ratio of the first hair coloring agent and the second hair coloring agent specified in step S44 may be transmitted.

When the registration process is executed in step S54, a message that the hair information after dyeing can be specified is transmitted from the server device 2 to the shop terminal 3 (step S55). The message that the hair information after dyeing can be specified is received at the shop terminal 3 (step S56). In step S56, in addition to the message that the hair information after dyeing can be specified, the hair information after dyeing may also be received. The notification process is completed by the above steps S51 to S56.

If the expected post-dye hair information cannot be identified in step S45, the notification process is not executed, and a message indicating that the hair information cannot be identified is displayed on the store terminal 3, and the process of step S47 may be executed. The notification process does not have to be executed. The notification process may be executed if the hair information to be displayed in step S35 cannot be identified or if the hair information cannot be identified in step S39.

In a second embodiment, the system may register information about the hair coloring agent used in the customer's treatment in the server device 2 in association with the store ID and/or user ID. This specifically stores the type and amount of the first hair coloring agent or the second hair coloring agent used throughout the store. The system may calculate the inventory amount of the first hair coloring agent or the second hair coloring agent throughout the store. By checking the system, the store staff can know the type and amount of the first hair coloring agent or the second hair coloring agent used throughout the store. This eliminates the need for cumbersome inventory.

In a second embodiment, the system may register the stock amount of the first hair coloring agent or the second hair coloring agent in the system and subtract the amount of the first hair coloring agent or the second hair coloring agent that has been used. This allows the store clerk to easily know which first hair coloring agent or the second hair coloring agent is about to run out of stock. In addition, the store clerk can efficiently place orders for the first hair coloring agent or the second hair coloring agent.

In the second embodiment, the system can disclose the type and ratio of the first hair coloring agent or the second hair coloring agent used in the treatment registered in step S48. This allows the store staff to refer to the treatment contents of other hairdressers. The scope of disclosure of the type and ratio of the first hair coloring agent or the second hair coloring agent used in the treatment may be the scope of users who use the same store ID, or a specified group may be created and the scope of users who use a user ID associated with the group may be disclosed.

In the system of the second embodiment, the type and proportion of the first hair coloring agent or the second hair coloring agent used in the treatment is stored in association with the user ID. Therefore, the administrator can identify and make public the type and proportion of the first hair coloring agent or the second hair coloring agent used by a popular hairdresser.

In the second embodiment, the system can identify the type and ratio of the first hair coloring agent or the second hair coloring agent that is used frequently. This makes it possible to identify trendy coloring. Also, in the second embodiment, the system stores the type and ratio of the first hair coloring agent or the second hair coloring agent used in the treatment in association with the user ID. This allows the store clerk to review the details of their own treatment.

Third embodiment
The outline of the third embodiment of the present invention will be described below. In the following, as the third embodiment of the present invention, a system for specifying the type and amount of a first hair coloring agent (also called the first hair coloring agent) and/or a second hair coloring agent (also called the second hair coloring agent) for dyeing a customer's hair at a store terminal 3 will be exemplified and described. Note that the configuration of the system, the administrator terminal 1, the server device 2, and the store terminal 3 can adopt the contents described in the second embodiment to the extent necessary.

[Registration process]
The registration process according to the third embodiment will now be described. The registration process according to the second embodiment (FIG. 7) can be applied to the registration process according to the third embodiment.

In the third embodiment, in the registration process shown in FIG. 7, the server device 2 stores information that allows the color and/or brightness of the hair after dyeing with the hair coloring agent to be understood in association with the hair coloring agent (also called hair color agent) and the color and/or brightness of the hair before dyeing. Also, in the third embodiment, in the registration process shown in FIG. 7, the server device 2 may store information that allows the color and/or brightness of the hair after dyeing with the first hair coloring agent to be understood in association with the first hair coloring agent, the second hair coloring agent, and the color and/or brightness of the hair before dyeing.

The format of the information that allows the hair color and/or brightness to be grasped is not particularly limited. The information that allows the hair color and/or brightness to be grasped may be numbers, letters, symbols, or images. The information that allows the hair color and/or brightness to be grasped may also be a combination of one or more of numbers, letters, symbols, and images. The information that allows the hair color and/or brightness to be grasped is displayed on the display screen as numbers, letters, symbols, and/or images.

When the information that allows one to grasp the color and/or brightness of hair is an image, the information that allows one to grasp the color and/or brightness of hair may be a color image or an image of a hair bundle. From the viewpoint of making it easy to visually grasp the content, it is preferable that the information that allows one to grasp the color and/or brightness of hair is a color image or an image of a hair bundle. Note that in the third embodiment, the information that allows one to grasp the color and/or brightness of hair may be referred to as hair information.

In the third embodiment, the hair information input in step S24 is, for example, information that allows the color and/or brightness of the hair after dyeing to be understood. The hair is the hair input in step S21, to which the type of hair coloring agent input in step S22 is prepared and applied in the ratio input in step S23, and after a predetermined time has passed, the hair coloring agent is washed off and the hair is dried.

In the third embodiment, the hair dye information includes information that allows the user to grasp the color and/or brightness of the hair before dyeing, the type and proportion of hair coloring agent, and the color and/or brightness of the hair after washing, which were input in steps S21 to S24. In step S27, the information that allows the user to grasp the color and/or brightness of the hair before dyeing, the type and proportion of hair coloring agent, and the color and/or brightness of the hair after washing, which were input in steps S21 to S24, are associated and registered as one data set. The hair information is stored in association with the color and/or brightness of the hair before dyeing, and the type and proportion of hair coloring agent.

In the third embodiment, it is preferable that an image is input as the hair information. In step S24, an image stored in the storage unit 13 of the administrator terminal 1 or an image obtained by photographing the state of the hair after dyeing on the spot may be input by selection.

In addition, when an image is input as hair information, it is preferable that a different image is input for one or more different color temperatures and/or illuminances and stored in the server device 2. In step S24, the administrator may selectively input multiple images as one piece of hair information to be associated with the color and/or brightness of the hair before dyeing and the type and proportion of the hair coloring agent. In other words, the server device 2 may store information for each of multiple color temperatures that allows the color and/or brightness of the hair to be recognized under a light source having that color temperature, and may store information for each of multiple illuminances that allows the color and/or brightness of the hair to be recognized when light is irradiated to the hair at that illuminance.

In the system of the third embodiment, similar to the system of the second embodiment, multiple different images are stored for one state of hair after dyeing. For each of multiple color temperatures, the color and/or brightness of the hair as seen under a light source having that color temperature may be represented by numbers, letters, and/or symbols, and for each of multiple illuminances, the color and/or brightness of the hair as seen when light is irradiated onto the hair at that illuminance may be represented by numbers, letters, and/or symbols.

In the system of the third embodiment, as in the system of the second embodiment, for example, information that can grasp the color and/or brightness of one hair may be stored, such as an image of hair taken under a light source of 2000K, an image of hair taken under a light source of 6500K, etc.

Furthermore, in the system of the third embodiment, as in the system of the second embodiment, for example, information that allows one to grasp the color and/or brightness of one hair may be stored, such as an image of the hair that is visually recognized when light is irradiated onto the hair at 300 lx, an image of the hair that is photographed when light is irradiated onto the hair at 100 lx, etc.

In the third embodiment, in step S27, the server device 2 also stores the hair dye information in the hair dye information management table, but the hair dye information management table in the third embodiment can be the same as the hair dye information management table shown in Figure 8 described in the second embodiment.

By executing the registration process shown in FIG. 7, the system can store in advance information about the color and/or brightness of the hair that will be dyed when a certain hair coloring agent is used with a certain undercolor or undertone of hair. This makes it possible to specify the color and/or brightness of the hair that the customer expects after the hair is actually dyed, based on the customer's desired color and/or brightness of the hair after dyeing and the undercolor and undertone of the customer's hair.

[Specific Processing]
Next, the specification process related to the system of the third embodiment will be described. In the specification process, input of the desired hair color and/or brightness after dyeing and the hair color and/or brightness before dyeing is accepted, and the hair dye information management table is referred to to specify a hair coloring agent for dyeing the hair to the desired hair color and/or brightness after dyeing, and information that can grasp the hair color and/or brightness after dyeing that corresponds to the input hair color and/or brightness before dyeing. The specification process can be executed after one or more pieces of hair information are registered in the registration process.

The identification process may further include accepting an input of a second hair coloring agent, and referring to a hair dye information management table to identify the input second hair coloring agent, the input first hair coloring agent for dyeing the hair to the desired color and/or brightness after dyeing, and information that can grasp the color and/or brightness of the hair after dyeing that corresponds to the input color and/or brightness of the hair before dyeing.

Figure 13 is a diagram showing a flowchart of the specific processing according to the third embodiment. First, a store clerk starts an application program downloaded to the store terminal 3 and accesses the server device 2 to log in to the system. Logging in to the system is similar to the specific processing according to the second embodiment.

Next, the store clerk operates the store terminal 3 to input the hair dyeing method for the customer who is to have his/her hair dyed (step S61). Step S61 is the same process as step S31.

Next, the store clerk operates the store terminal 3 to input the hair type corresponding to the customer's hair (step S62). Step S62 is the same process as step S32.

Next, the store clerk operates the store terminal 3 to input the desired color and/or brightness of the hair after dyeing (step S63). In step S63, numbers, letters, symbols, etc. may be input as the color and/or brightness of the hair, or an image may be input by selection. In step S63, the first hair color agent may also be input.

In step S63, for example, a color image or an image of a bundle of hair stored as hair information is displayed on the display screen of the store terminal 3, and the desired color and/or brightness of the hair after dyeing may be input by selecting an image having the desired color and/or brightness of the hair after dyeing from among the displayed color images or images of a bundle of hair.

Specifically, as shown in the display screen 70 in FIG. 10, color images or images of hair strands after dyeing may be displayed in a matrix in correspondence with the color and brightness associated with the first hair color agent. The store clerk can find out the customer's desire as to what color to dye the hair by referring to the color images or hair strand images displayed on the store terminal 3. The store clerk selects an image that has the color and/or brightness of the customer's desired hair after dyeing.

In addition, when the color image or hair bundle image is displayed on the display screen of the store terminal 3, the displayed color image or hair bundle image may be a list of images corresponding to hair information stored in the server device 2, may correspond to specific hair information selected by operation of the manager terminal 1 or the store terminal 3, or may correspond to hair information stored in association with a hair coloring agent from a specific manufacturer. The hair information selected by operation of the manager terminal 1 or the store terminal 3 is not particularly limited, but may be, for example, hair information corresponding to a hair coloring agent available in the store.

Furthermore, in step S63, the manufacturer of the hair coloring agent is displayed first, and the specific manufacturer to be used for the treatment may be input, and then the desired color and/or brightness of the hair after dyeing may be input. In this case, a color image or a hair bundle image corresponding to the hair information stored in association with the hair coloring agent of the input manufacturer is displayed.

In the following steps S64 to S68, the color and/or brightness of the hair before dyeing and the second hair color agent are input for each of the areas input in step S62 (e.g., the area of the roots of the hair, the area of the center of the hair, the area of the tips of the hair, etc.), and the desired state of the hair after dyeing is selected. Because the color and/or brightness of the hair before dyeing, the second hair color agent, and the desired state of the hair after dyeing are input in steps S64 to S68, in step S69, the server device 2 can identify the first hair color agent to be used for each of the areas input in step S62.

Next, for one region in the hair type selected in step S62, the store clerk operates the store terminal 3 to input the color and/or brightness of the customer's undyed hair corresponding to that region (step S64). In step S64, in addition to the color and/or brightness of the undyed hair, the store clerk also inputs to the store terminal 3 the length of the customer's hair corresponding to that region, whether the hair is gray or colored, etc. If the hair is gray, the store clerk may also input to the store terminal 3 the percentage of gray hair in the total hair.

Next, the store clerk operates the store terminal 3 to input the type or concentration of the second hair color agent (step S65). Step S65 is the same process as step S34.

When the necessary information is input at the store terminal 3 in steps S63 to S65, this information is transmitted to the server device 2, and the server device 2 identifies the expected post-dye hair information based on the transmitted information (step S66). The identified post-dye hair information is transmitted to the store terminal 3, and the post-dye hair information is displayed on the store terminal 3 (step S67). Note that the post-dye hair information displayed in step S67 may be one piece, or two or more pieces.

Here, the predicted hair information after dyeing refers to information that allows one to grasp the predicted color and/or brightness of the hair when a specific hair coloring agent is applied to the customer's undyed hair, rinsed off after a specific time has passed, and then dried.

The process of step S66 will be described. The process of step S66 includes the processes of steps S66-1 to S66-3. First, the server device 2 identifies a first hair coloring agent for dyeing hair to the desired color and/or brightness of the dyed hair input in step S63 (step S66-1). Specifically, in the hair dye information management table, a first hair coloring agent stored in association with information that allows the input desired dyed hair color and/or brightness to be grasped is identified as the first hair coloring agent for dyeing hair to the input desired color and/or brightness of the dyed hair. The first hair coloring agent for dyeing hair to the desired color and/or brightness of the dyed hair may be a first hair coloring agent associated with the desired color and/or brightness of the dyed hair.

Here, the hair information displayed in step S63 may display, for example, images of hair dyed with one different type of first hair coloring agent for hair with a "natural" color and a hair brightness level of "4" before dyeing. Therefore, when the desired color and/or brightness of hair after dyeing is input as an image in step S63, the server device 2 can refer to the hair dye information management table based on the desired color and/or brightness of hair after dyeing input in step S63 and identify that the image of hair with a brightness level of "4" before dyeing is dyed with the first hair coloring agent "A1". In this way, "A1" is identified as the first hair coloring agent for dyeing hair to the desired color and/or brightness of hair after dyeing input. It is preferable that there is only one type of first hair coloring agent stored in association with the hair information displayed in step S63.

The color and/or brightness of the hair before dyeing stored in association with the hair information displayed in step S63 may be the same as or different from the color and/or brightness of the customer's hair before dyeing input in step S64.

If the desired color and/or brightness of the hair after dyeing is input using numbers, letters, or symbols in step S63, the server device 2 identifies a first hair color agent associated with the input color and/or brightness in step S66-1. If a first hair color agent is input in step S63, the server device 2 identifies the first hair color agent in step S66-1.

Next, a hair dye information management table to be referred to when identifying the expected hair information is identified (step S66-2). For example, a hair dye information management table corresponding to the manufacturer, hair color, or second hair color may be identified from the manufacturer of the first hair coloring agent input in step S63, the hair color information input in step S64, or the information of the second hair coloring agent input in step S65. Then, the identified hair dye information management table is referenced from the identified first hair coloring agent and the color and/or brightness of the hair before dyeing input in step S64, and the hair information stored in association with the first hair coloring agent and the color and/or brightness of the hair before dyeing is identified (step S66-3). This allows the expected hair information to be identified when a hair coloring agent containing the identified first hair coloring agent and the input second hair coloring agent is applied to the customer's hair before dyeing, washed off after a predetermined time has passed, and dried.

Furthermore, in step S66, the system may refer to the hair dye information stored in the registration process to identify a hair coloring agent that has a predetermined correlation with the hair coloring agent for dyeing the hair to the desired color and/or brightness after dyeing, and information that can grasp the color and/or brightness of the hair after dyeing that corresponds to the input color and/or brightness of the hair before dyeing. In other words, the process of step S66 can also be executed as follows. Note that explanations of similar processes may be omitted.

Specifically, the server device 2 can refer to the identified hair dye information management table and identify the first hair color agent that has a predetermined correlation with the first hair color agent identified from the desired dyed hair color and/or brightness input in step S63, and the hair information stored in association with the input undyed hair color and/or brightness.

The first hair coloring agent having a predetermined correlation with the identified first hair coloring agent may be, for example, a hair coloring agent having the same color or brightness as the color or brightness of the identified first hair coloring agent. Specifically, it may be a hair coloring agent having the same color but different brightness, or a hair coloring agent having the same brightness but different color.

Also, for example, the first hair coloring agent having a specified correlation may be a hair coloring agent having a color and/or brightness within a specified range of the color and/or brightness of the identified first hair coloring agent.

A hair coloring agent having a color and/or brightness within a predetermined range from the color and/or brightness of the first hair coloring agent is, for example, a hair coloring agent having the same color as the specified hair coloring agent, but with a predetermined range of difference in brightness. The predetermined range of difference in brightness may be a predetermined range of level difference from the specified brightness level (for example, ±2 levels). Specifically, when the first hair coloring agent of "R6" is specified, the first hair coloring agents having a predetermined correlation may be the first hair coloring agents of "R4", "R5", "R7" and "R8". In addition, a hair coloring agent having a color and/or brightness within a predetermined range from the color and/or brightness of the first hair coloring agent is, for example, a hair coloring agent having the same brightness as the specified hair coloring agent, but with a predetermined range of difference in color. The predetermined range of difference in color may be adjacent colors on the color wheel.

For example, a first hair coloring agent having a predetermined correlation may be a first hair coloring agent that contains a specified first hair coloring agent at a specified ratio or more. Specifically, when a first hair coloring agent is a mixture of two or more types, the specified first hair coloring agent may be considered to have a predetermined correlation if the ratio of the specified first hair coloring agent to the total amount of the first hair coloring agent is a specified ratio or more (e.g., 30% or more). When a first hair coloring agent "R6" is identified, if first hair coloring agents "R3", "R6" and "N3" are mixed in a ratio of "1:2:1", this first hair color can be considered to have a predetermined correlation.

Also, for example, a first hair coloring agent having a predetermined correlation may be a first hair coloring agent that contains the most of a specified first hair coloring agent. Specifically, when two or more types of first hair coloring agents are mixed, a first hair coloring agent may be considered to have a predetermined correlation if the proportion of the specified first hair coloring agent in the total amount of the first hair coloring agent is the largest compared to the other first hair coloring agents.

Also, for example, the first hair coloring agent having a predetermined correlation may be a hair coloring agent made by the same manufacturer or a hair coloring agent that is in stock at the store.

The hair dye information management table identified in step S66 may be within a range that has a predetermined correlation with the hair color input in step S64 or the type of the second hair coloring agent input in step S65. The range that has a predetermined correlation with the hair color may be, for example, a range of colors close to the color. The range that has a predetermined correlation with the type of the second hair coloring agent may be, for example, a range of types close to the concentration of the second hair coloring agent.

In addition, in step S66, the system may further identify information that allows for grasping the color and/or brightness of the hair after dyeing that has a predetermined relationship with the input desired color and/or brightness of the hair after dyeing. In other words, the processing of step S66 can also be executed as follows. Note that explanations of similar processing may be omitted.

For example, by referring to the identified hair dye information management table, hair information that has a predetermined relationship with the desired hair color and/or brightness entered in step S63 can be identified.

Hair information having a predetermined relationship with the desired hair color and/or brightness may be, for example, hair information having a color and/or brightness close to the desired hair color and/or brightness. Specifically, when the hair information stored in the hair dye information management table is image data, it may refer to image data indicating the input desired hair color and/or brightness and image data in the hair dye information management table converted into RGB values, which are the same or have an error within a predetermined range. Also, when the hair information stored in the hair dye information management table is stored as a numerical value indicating the hair color and/or brightness, it may refer to hair information that is the same or has an error within a predetermined range as the numerical value indicating the input desired hair color and/or brightness.

If multiple hair information items are identified in step S66, all of the identified hair information items may be displayed in step S67, or only some of the hair information items may be displayed. For example, in step S67, hair information items stored in association with hair coloring agents that are in large stock at the store or hair coloring agents that have a short expiration date may be preferentially displayed. Also, in step S67, hair information items stored in association with a small number of types of hair coloring agents may be preferentially displayed. Alternatively, if a hair coloring agent that contains two or more types of hair coloring agents is identified, the hair information items may not be displayed on the store terminal 3 in step S67, and may be displayed in a separate window by inputting an operation to the store terminal 3. The store clerk can confirm the hair information items as variations.

Here, the display screen displayed on the store terminal 3 in step S67 will be described. In step S67, the server device 2 may be controlled to display information that allows the user to grasp the desired hair color and/or brightness after dyeing input in step S63, and information that allows the user to grasp the specified hair color and/or brightness after dyeing. FIG. 11 is also a diagram showing an example of a display screen according to the third embodiment.

The display screen displayed on the store terminal 3 in step S67 differs from the display screen displayed on the store terminal 3 in step S40 in the following respects.
- The application result 41 is information that enables the color and/or brightness of the hair after dyeing identified in step S66 to be understood. - The desired color 42 is information that enables the color and/or brightness of the hair after dyeing that was desired and input in step S63 to be understood. - The color and/or brightness of the hair before dyeing that is associated with the desired color 42 may be the same as the color and/or brightness of the hair before dyeing that was input in step S66, or may be different. - The input information 43 corresponds to the information input in steps S64 and S65. The other configurations of the display screen displayed on the store terminal 3 in step S67 are the same as the display screen on the display terminal 3 at the store terminal 3 in step S40, so explanations will be omitted.

Returning to the explanation of the flowchart of the identification process in FIG. 13, when the predicted post-dye hair information is displayed in step S67, the store clerk operates the store terminal 3 to select one of the hair information (step S68). The server device 2 refers to the hair dye information management table from the hair information selected in step S68, and identifies the type and proportion of hair coloring agent stored in association with the hair information. The identified type and proportion of hair coloring agent is displayed on the store terminal 3 (step S69).

In step S69, the total amount of hair coloring agent and the amount of each hair coloring agent may be displayed. The total amount of hair coloring agent can be calculated from an application amount calculation table that associates hair length with the amount of hair coloring agent, based on the undyed hair length input in step S64. The application amount calculation table is stored in the server device 2. The amount of each hair coloring agent can be calculated based on the proportion of the hair coloring agent and the total amount of hair coloring agent.

In the following steps S70 to S72, it is possible to change the type and proportion of the hair coloring agent displayed in step S69, and fine-tune the hair coloring agent used in the treatment, such as adding a different color or changing the brightness. In addition, the condition of the hair after dyeing with the fine-tuned hair coloring agent can be displayed. Since the color and/or brightness of the hair before dyeing and the second hair coloring agent are input in steps S64 and S65, in step S71 the server device 2 can identify the condition of the hair after dyeing with the fine-tuned hair coloring agent.

When the type and proportion of hair coloring agent are displayed in step S69, the store clerk operates the store terminal 3 to execute an amount specification process to specify the amount of hair coloring agent to be used in the actual treatment (step S70). The amount specification process can be the amount specification process in the first embodiment or a detailed amount specification process.

Specifically, when using the amount determination process in the first embodiment, the type and amount of hair coloring agent determined in step S70 are displayed on the display screen 100 in FIG. 3. For example, the type of the first coloring agent is displayed in the first substance display field 111, and the amount of the first coloring agent is displayed in the usage amount display field 113. The user can add, delete, change, etc. the element E, the calculation rule R, and the numerical value I, as well as the ratio or amount of the first hair coloring agent and the second hair coloring agent displayed in the first substance total amount display field 102 and the second substance total amount display field 103.

Next, the server device 2 refers to the hair dye information management table and identifies the hair information after dyeing that is expected to be done with the identified hair coloring agent based on the type and ratio of the hair coloring agent identified by the amount identification process and the information input in step S64 (step S71). The processing method of step S71 will be described later.

The hair information after dyeing that is predicted using the identified hair coloring agent is displayed on the store terminal 3 (step S72). If the store clerk determines that there is no problem with the hair color and/or brightness of the displayed hair information, the store clerk operates the store terminal 3 to determine that the hair coloring agent identified in step S70 is the hair coloring agent to be used for treating one area included in the hair pattern (step S73). On the other hand, if the proportion and/or amount of the hair coloring agent is to be further adjusted to change the hair color and/or brightness of the hair information displayed in step S72, the processing from steps S70 to S72 is executed again.

The process of steps S64 to S73 is performed for each region included in the hair pattern input in step S72, so steps S64 to S73 are repeatedly performed until input is complete for all regions. When the process of step S73 has been performed for all regions included in the hair pattern, the repeated process of steps S64 to S73 ends.

When the process has been repeated for all areas included in the hair pattern, the type and ratio of the hair coloring agent determined in step S73 is stored and registered in the server device 2 as the hair coloring agent to be used in the customer's treatment by the store clerk operating the store terminal 3 (step S74). The process of step S74 is the same as the process of step S48.

When the type and ratio of hair coloring agent are registered in step S74, information regarding the type and ratio of hair coloring agent is notified from the server device 2 or the store terminal 3 to the manager terminal 1 (step S75). The process of step S75 is the same as the process of step S49. After steps S61 to S75, the identification process ends.

The identification process may be executed by only one computer device. The processes of steps S61 to S63 may be executed in a reverse order. The process of step S65 may be omitted. In this case, it is preferable that the type or concentration of the second hair color agent is set in advance in the server device 2. The processes of steps S63 and S68 may be executed by the customer himself operating the store terminal 3.

The process of step S71 will now be described. In the server device 2, the hair dye information management table is referenced based on the type and ratio of hair coloring agent displayed on the display screen 50 and the color and/or brightness of the hair before dyeing input in step S64, and the corresponding post-dye hair information is identified.

The process of step S71 differs from the process of step S45 in the following respects.
The post-dye hair information that is identified is based on the types and ratios of the hair colorants displayed on the display screen 50 or the types and ratios of the hair colorants identified in step S70, rather than the types and ratios of the first and second hair colorants identified in step S44. The other configurations of the processing in step S71 are the same as those of the processing in step S45, so explanations will be omitted.

If the type and ratio of hair coloring agent displayed on the display screen 50 and the post-dye hair information are not stored in the hair dye information management table in association with the color and/or brightness of the hair before dyeing input in step S64, the expected post-dye hair information cannot be identified in step S71. The type and ratio of hair coloring agent displayed on the display screen 50 are also referred to as the type and ratio of hair coloring agent identified in step S70. In that case, a notification process may be executed in which the server device 2 notifies the store terminal 3 and the administrator terminal 1 of missing information indicating that the post-dye hair information cannot be identified.

Note that the processing of steps S71 and S72 may be omitted. If the processing of steps S71 and S72 is omitted, when the administrator receives the notification in step S75, if the hair information corresponding to the notified type and ratio of hair coloring agent is not registered in the hair dye information management table, the administrator can execute the above-mentioned registration processing. At this time, the notification in step S75 transmits missing information indicating that no information capable of grasping the color and/or brightness of the hair after dyeing has been stored. The missing information may include information that prompts the administrator to register information capable of grasping the color and/or brightness of the hair after dyeing, or information that requests the administrator to register.

In other words, the process of step S75 can be said to be a process of sending missing information to the manager terminal 1, which is the second computer device, when information that allows the color and/or brightness of the hair after dyeing is not stored for the hair coloring agent input at the store terminal 3, which is the first computer device.

The shortage information may also include information regarding the number of times that the type and ratio of the first hair coloring agent and the second hair coloring agent have been notified. The administrator may execute the above-mentioned registration process for the types and ratios of hair coloring agents that have been notified a predetermined number of times or more. In the registration process, the notified type and ratio of hair coloring agent used for hair dyeing is associated with the color and brightness of the hair before dyeing, and the hair dyeing information is stored in the hair dyeing information management table. In other words, in the server device 2, information that can grasp the color and/or brightness of the hair after dyeing, which corresponds to the shortage information transmitted in step S75 and was input at the administrator terminal 1, is stored in association with the hair coloring agent. The notification process in step S75 corresponds to step S51 in the second embodiment, and the above-mentioned registration process corresponds to steps S53 to S54 in the second embodiment.

The registered hair information may be displayed in the new identification process in the process of step S67 or S72. In other words, by referring to the stored hair dye information management table, information that allows the color and/or brightness of the dyed hair to be grasped, corresponding to the hair coloring agent for dyeing the hair to the desired color and/or brightness, inputted in the manager terminal 1 or another store terminal 3, which is a third computer device, can be identified. Furthermore, information that allows the color and/or brightness of the dyed hair to be grasped, corresponding to the hair coloring agent having a predetermined correlation with the hair coloring agent for dyeing the hair to the desired color and/or brightness, inputted in the manager terminal 1 or another store terminal 3, can be identified. The identification process can be executed in the same manner as the processes of steps S61 to S75.

In the above-mentioned specific process, we have described a method of uniformly coloring the entire customer's hair, but this is not limited to this, and the process can also be applied to coloring different parts of the hair with different colors.

In the case of coloring in which the color is varied within a single hair, after steps S61 and S62 are executed, the desired color and/or brightness of the hair after dyeing is input in step S63 for each region of the hair included in the hair pattern, and the processing of steps S64 to S73 is executed repeatedly. Then, steps S74 and S75 are executed, and the identification processing ends. Furthermore, when the desired color and/or brightness of the hair after dyeing differs within the same region included in the hair pattern, the processing of steps S64 to S73 is executed repeatedly for each desired color and/or brightness of the hair after dyeing.

In the case of coloring in which the color is different for each part of the hair that grows therein, in step S61, the part for which the color and/or brightness is desired for each desired color and/or brightness of the hair after dyeing may be input. Next, the processing of steps S62 to S73 is repeatedly executed for each input part. Then, steps S74 and S75 are executed, and the identification processing ends. For example, in the case of coloring in which the color is different for the front hair and other parts, in step S11, the front hair and other parts are input as the parts of the hair to be dyed. Then, the processing of steps S62 to S73 is executed for the front hair part and other parts, respectively.

[Amount Specification Processing]
Here, the amount determination process of step S70 will be described. In the amount determination process of the third embodiment, the amount of each hair coloring agent included in the hair coloring agent group, the ratio of each hair coloring agent to the total amount, and/or the ratio of the amount of the hair coloring agent are calculated based on the input percentage and ratio. Then, the amount of each hair coloring agent is determined.

The amount specification process is used by the store clerk to fine-tune the type and proportion of hair colorant displayed by the process in step S69. For example, this process is performed when the customer has a large amount of hair and the total amount of hair colorant to be applied needs to be increased. Also, for example, when the store clerk checks the post-dye hair information and feels that the hair has a strong reddish tinge, this process is performed when the store clerk wants to add a certain proportion of green hair colorant to the displayed hair colorant to remove the reddish tinge.

Figure 14 is a diagram showing a flowchart of the amount determination process according to the third embodiment. First, the store clerk checks the types and proportions of hair coloring agents displayed in step S69 on the store terminal 3. Specifically, the types and proportions of the first hair coloring agent, the types and proportions of the second hair coloring agent, and the proportions of the first hair coloring agent and the second hair coloring agent.

The store clerk operates the store terminal 3 to select the hair coloring agent to be used for the treatment (step S81). In step S81, the store clerk may select from the displayed hair coloring agents, or may input a new, different hair coloring agent.

Next, the store clerk operates the store terminal 3 to input the ratio of the amount of each hair coloring agent contained in the hair coloring agent (A) to the total amount of the hair coloring agent group (step S82). The store terminal 3 accepts the input of the ratio for one type of hair coloring agent (A) or two or more types of hair coloring agents, but the input ratios are input so that the total does not exceed 100%.

Here, the hair color agent group is composed of hair color agent (A) containing at least one hair color agent, and hair color agent (B) containing at least two or more hair color agents. In addition, whether the hair color agent included in the hair color agent group is hair color agent (A) or hair color agent (B) can be arbitrarily changed by the store clerk operating the store terminal 3.

The first hair coloring agent as a whole can be treated as a first hair coloring agent group, and the second hair coloring agent as a whole can be treated as a second hair coloring agent group. Similarly, when there are two or more hair coloring agent groups, the ratio of the hair coloring agents contained in each hair coloring agent group, the ratio of the amounts of the hair coloring agents, and/or the amounts of the hair coloring agents can be specified. The first hair coloring agent and the second hair coloring agent may be collectively treated as a hair coloring agent group.

Next, the store clerk operates the store terminal 3 to input the ratio of the amounts of each hair coloring agent contained in the hair coloring agent (B) (step S83). Note that if the hair coloring agent (B) is composed of one hair coloring agent, the ratio may be input as "1."

Next, the store clerk operates the store terminal 3 to input a change in the total amount of the hair color agent group (step S84). The change in the total amount of the hair color agent group may be input by inputting the total amount of two or more hair color agent groups. For example, the change may be input by changing the total amount of the first hair color agent group and the second hair color agent group. By inputting the ratio between the first hair color agent group and the second hair color agent group, the total amount of each hair color agent group can be calculated, and this can be used as an input of a change in the total amount of the hair color agent group.

Based on the information entered in steps S81 to S84, the server device 2 or the store terminal 3 specifies the respective proportions of hair coloring agents, the ratio of the amounts of hair coloring agents, and/or the amounts of hair coloring agents (step S85). The specified respective proportions of hair coloring agents, the ratio of the amounts of hair coloring agents, and/or the amounts of hair coloring agents are then displayed on the store terminal 3 (step S86). Note that when the specified respective proportions of hair coloring agents or the ratio of the amounts of hair coloring agents are displayed, a store clerk may use the displayed information to calculate the amount of each hair coloring agent. The amount specification process ends with the processing of steps S81 to S86.

The amount specification process may be executed by only one computer device, or may be executed by a system consisting of multiple computer devices, such as the store terminal 3 and the server device 2. For example, the input and selection processes in steps S81 to S84 may be executed by the store terminal 3, the specification process in step S85 may be executed by the server device 2, and the display process in step S86 may be executed by the store terminal 3. In this case, information is sent and received between the store terminal 3 and the server device 2 as appropriate.

Here, the processing of step S85 will be described. First, it is assumed that the percentage remaining after subtracting the percentage entered in step S82 from the total is the percentage of hair color agent (B) relative to the total amount of the hair color agent group.

Specifically, the sum of the percentages input in step S82 is the percentage relative to the total amount of the hair coloring agent group. Next, the percentage input in step S82 is subtracted from 100%. Then, in step S85, the percentage of each hair coloring agent or the ratio of the amount of hair coloring agent is calculated using the ratio input in step S83 as the ratio within the subtracted percentage. The amount of each hair coloring agent can be calculated from the calculated percentage or ratio of each hair coloring agent and the total amount of the hair coloring agent group received in step S84.

For example, for a hair color agent group including hair color agents X, Y, and Z, assume that 20% is input as the proportion of hair color agent X in step S82. Hair color agent X is included in hair color agent (A), and hair color agents Y and B are included in hair color agent (B). In this case, the proportion of hair color agent (B) to the total amount of the hair color agent group is 80%, which is 100% minus 20%.

Then, in step S83, the ratio of hair color agents Y and Z can be input as 1:3. In other words, the percentages of hair color agents X, Y, and Z in the entire hair color agent group are calculated as 20%, 20%, and 60%, respectively. When the total amount of the hair color agent group is 100g, the amounts of hair color agents X, Y, and Z are 20g, 20g, and 60g, respectively.

The processes of steps S81 to S84 may be executed in the reverse order. Furthermore, the process of step S81, S82, S83, or S84 may be executed multiple times, such as by executing the process of step S81 after step S82, S83, or S84. When any of the processes of steps S81 to S84 is executed multiple times, the process of S85 is executed based on the input information of the process executed last.

In other words, if the process of S84 is executed last, the percentage or ratio of each hair coloring agent calculated from steps S82 and S83 can be fixed, and the amount of each hair coloring agent can be determined from the total amount input in step S84. Also, if step S82 or S83 is executed after executing step S84, the total amount input in step S84 can be fixed, and the percentage, ratio, and/or amount of each hair coloring agent can be determined.

The processes of steps S81, S82, S83, and/or S84 may be omitted. Also, if the hairdresser determines in step S69 that the displayed types and proportions of hair coloring agents are acceptable, steps S81 to S83 can be omitted and the processes from step S84 onwards can be carried out.

Here, the input screen displayed in the amount determination process will be described. FIG. 15 is a diagram showing an example of a display screen relating to the third embodiment. Specifically, this is the display screen displayed in step S86. Display screen 50 displays a calculation method input field 51, a first hair coloring agent display field 52, a ratio/proportion display field 53, and a usage amount display field 54. Also displayed are a second hair coloring agent display field 55, a ratio/proportion display field 56, and a usage amount display field 57.

The calculation method input field 51 is used to input the calculation method for determining the ratio and/or amount of the first hair color agent group as a whole in the amount determination process. When "Ratio + %" is selected, the processing of steps S81 to S86 is executed for the first hair color agent group. When "Ratio" is selected, the processing other than step S82 is executed for the first hair color agent group. In other words, the ratio and/or amount of the first hair color agent is determined by the ratio only. The calculation method input field 51 may also display "%". When "%" is selected, the processing other than step S83 is executed for the first hair color agent group. In other words, the ratio and/or amount of the first hair color agent is determined by the ratio only. Note that "Ratio + %" is selected in the calculation method input field 51 on the display screen 50.

The first hair coloring agent display field 52 displays the type of first hair coloring agent used for hair coloring. The corresponding first hair coloring agent can be deleted by selecting the cancel icon 59. Also, any first hair coloring agent may be added by selecting the cancel icon 59. The ratio/proportion display field 53 displays a ratio/proportion input field 58 for each first hair coloring agent. The ratio/proportion input field 58 may be displayed when "ratio + %" is selected in the calculation method input field 51.

By selecting the ratio/proportion input field 58, it is possible to select whether to input a ratio in step S82 or a ratio in step S83. If "%" is selected, a ratio can be input in step S82, and if "ratio" is selected, a ratio can be input in step S83. On the display screen 50, "ratio" has been selected for the hair coloring agents "A5", "A6", and "N6", and "%" has been selected for the hair coloring agent "N8". The store clerk can input and change the percentage and ratio as desired.

The usage amount display field 54 displays the usage amount of the specified hair coloring agent based on the information entered in the ratio/proportion input field 58, the ratio/proportion display field 56, the ratio display field 61, and the total amount display field 62. The second hair coloring agent display field 55, the ratio/proportion display field 56, and the usage amount display field 57 have the same functions as the first hair coloring agent display field 52, the ratio/proportion display field 53, and the usage amount display field 54. In FIG. 15, the second hair coloring agent is applied with "ratio" as the calculation method, but like the first hair coloring agent, a calculation method input field is also displayed for the second hair coloring agent, and it is possible to input the calculation method used to specify the ratio and/or amount of the entire second hair coloring agent group.

The display screen 50 also displays a ratio display field 61 that displays the ratio of the first hair color agent to the second hair color agent, a total amount display field 62 that displays the total amount of the first hair color agent and the second hair color agent, and various icons 64. The total amounts of the first hair color agent and the second hair color agent may also be displayed.

The store clerk can change the values in the ratio display column 61 and the total amount display column 62 as desired. For example, the store clerk can decrease the total amount of hair coloring agent by selecting the total amount change icon 63a, or increase the total amount by selecting the total amount change icon 63b. At this time, the amount of hair coloring agent displayed in the usage amount display column 54 and the usage amount display column 57 is changed while maintaining the ratio or ratio displayed in the ratio/proportion display column 53 and the ratio/proportion display column 56. In other words, the total amount of the hair coloring agent group can be changed while maintaining the ratio or ratio of the hair coloring agents, and the amount of each hair coloring agent can be calculated.

Selecting icon 64a stops the execution of the amount determination process. Selecting icon 64b cancels the information entered by the store clerk, and the type and proportion of hair colorant displayed in step S19 is displayed on the display screen 50. Selecting icon 64c executes the process of step S71. Alternatively, the process of step S73 may be executed.

In the above embodiment, the amount of each hair coloring agent was calculated by inputting the percentage or ratio of the hair coloring agent contained in the hair coloring agent group, but the percentage or ratio of the hair coloring agent may also be calculated based on the amount of the hair coloring agent. Note that the following percentages and ratios are based on the assumption that the percentage remaining after subtracting the displayed percentage is the percentage of the hair coloring agent whose ratio is displayed relative to the total amount of the hair coloring agent group.

First, the store clerk operates the store terminal 3 to display the type, ratio, and amount of hair coloring agent stored in association with the hair information selected in step S68. Next, the store clerk operates the store terminal 3 to change the amount of one hair coloring agent. Based on the input amount of hair coloring agent and the displayed amounts of other hair coloring agents, the ratio of each hair coloring agent to the total amount of the hair coloring agent group and/or the ratio of the amounts of hair coloring agents is calculated.

For example, when the usage amount 54 of the first hair coloring agent "N8" is changed from "3 g" to "6 g" on the display screen 50, the ratio or ratio is calculated in the ratio/proportion display field 53, the ratio/proportion display field 56, and the ratio display field 61 according to the usage amount displayed in the usage amount 54 and the usage amount 57. The total amount display field 62 is calculated as "93 g" by adding the usage amount displayed in the usage amount 54 and the usage amount 57. Specifically, the ratio of the first hair coloring agent "N8" is displayed as "18", and the ratios of "A5", "A6", and "N6" are displayed as "3", "1", and "1", respectively. The ratio display field 61 displays "1.1:2" as the ratio of the first hair coloring agent group to the second hair coloring agent group. The ratio/proportion display field 56 and the usage amount 57 are not changed.

In the case where the proportion or ratio of the hair coloring agent is calculated based on the amount of the hair coloring agent, the calculated hair coloring agent may be displayed as a proportion to the total amount of the hair coloring agent group, or as a ratio of the hair coloring agent contained in the hair coloring agent group. In addition, when both a proportion and a ratio are displayed as in display screen 50, it is preferable to display it in the form of the proportion or ratio that was originally displayed.
