DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera capable of recording photographing information, and more particularly to a camera capable of recording photographing information with an improved method of selecting title information.

[0002]

2. Description of the Related Art Title information is one of the magnetically recordable information of an I × 240 cartridge film which has been used in recent years. That is, when the user selects one desired title from a plurality of pieces of title information and performs a shooting operation, a code corresponding to the selected title is recorded in the magnetic recording unit of the film. Then, the developer who receives the film reads the code and prints a title corresponding to the code when printing the photographic paper.

One of the methods for selecting title information as described above is to use display of date data on a camera. That is, when a specific switch (SW) is operated, a code corresponding to the title information is displayed on the date display member. Then, the user can select one title from a plurality of titles by operating the switch until a code corresponding to a desired title is displayed. Further, some cameras have a title selection function on a remote controller for remotely controlling the camera.

[0004]

However, in the above-mentioned title selection, only one title information can be displayed at a time in order to effectively use a small number of display members in any case. That is, from a state where one title information is displayed, a plurality of title information is scroll-displayed on the display member in conjunction with the operation of the switch of the user, and a desired title is searched. When the desired title is found, the information of the title is magnetically recorded by the user.

As described above, performing the scroll operation until the target title information appears on the display member takes a lot of time because it is difficult to obtain desired information when there is a large amount of title information.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and provides a camera capable of recording photographing information capable of obtaining desired information in a short time even if a display member having a small display capability is used.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. First, title information recorded on a camera capable of recording photographing information according to the present invention will be described.

Many of the currently used title information that can be magnetically recorded on an I × 240 cartridge film is related to an annual event. For example, one of the titles that can be printed is “show”. It is presumed that the user wants to select this title when using the camera in the month in which New Year is present, that is, January. It is difficult to imagine a user who selects “Ginger” other than January.

As described above, if the date when the photographing is performed can be determined, the title information that can be selected can be determined to some extent. The magnetically recordable information includes date information in addition to the title. Therefore, many cameras capable of magnetic recording have a built-in clock circuit for generating date information.

FIG. 2 is an external perspective view showing the configuration of an embodiment of a camera capable of recording photographing information according to the present invention. FIG.
1A, a camera capable of magnetically recording title information on a film has a lens barrel 2 mounted substantially at the center of the front surface of a camera body 1, and a finder 5 provided above the lens barrel. A power switch (SW) 3 and a release switch (SW) that enable the operation of the camera while the camera is on are arranged on the upper part of the camera body 1. When the release switch 4 is turned on, the film is exposed, the film is further wound, and magnetic recording is performed.

As shown in FIG. 2B, on the back of the camera body 1, there is provided a display section 6 for displaying exposure information and date information and for scrolling the title information when the title information is selected. It is arranged. A scroll switch (SW), which is an operation switch necessary for selecting the title information, is provided in the display section 6.
7, set switch (SW) 8, memory switch (S
W) 9 is provided. Further, a communication terminal 10 for performing communication with an external control device (not shown) is provided on a side surface of the camera body 1.

FIG. 1 is a diagram showing a configuration of a camera according to one embodiment of the present invention. In FIG. 1, a microcomputer 15 has a ROM 16 therein, and is for performing overall sequence control and various calculations shown by the camera. The microcomputer 15 includes the communication terminal 10, the display circuit 17, the photometry circuit 18, the shutter / aperture control circuit 19, and the EEPROM 2.
0, clock circuit 21, drive circuit 22, and magnetic recording circuit 23
And the power switch 3, release switch 4, scroll switch 7, set switch 8
And various switches of the memory switch 9 are connected.

The display circuit 17 displays exposure information and date information based on instructions from the microcomputer 15. At the time of title information selection operation,
Scroll the title information.

The photometric circuit 18 is a circuit for measuring the brightness of the subject. On the basis of the photometric data from the photometric circuit 18, the microcomputer 15 calculates the shutter speed and the aperture value during the exposure operation. The microcomputer controls the shutter / aperture control circuit 19 based on the calculation result.

The EEPROM 20 stores parameters necessary for the sequence operation of the camera, correction values for correcting the output of the photometric circuit 18, and the like. Further, data related to the title information is also stored in the EEPROM 20. By connecting the external control device 30 to the communication terminal 10, the information in the EEPROM 20 can be rewritten. The external control device 30 is an adjustment device used in a camera manufacturing process, a camera service center, or the like.

The clock circuit 21 includes "year", "month",
This is a circuit for generating date information of "day", "hour", and "minute". The drive circuit 22 is a circuit for driving an actuator such as a motor for operating the film feeding mechanism 25. The film feeding mechanism 25 is a mechanism for performing operations such as feeding, winding, and rewinding the film 27 from the cartridge 26.

The magnetic recording circuit 23 drives a magnetic head 28 to magnetically record predetermined information on the film 27. In such a configuration, the microcomputer 1
When the on state of the power switch 3 is detected at 5, the operation is started. When the release switch 4 is turned on, a photographing operation is performed. Further, the microcomputer 15 controls the drive circuit 22 to wind up the film 27 by one frame. In parallel with this winding operation, the microcomputer 15 controls the magnetic recording circuit 23,
Predetermined information (date information, title information) is magnetically recorded on the film 27.

In accordance with the operation of the scroll switch 7, the set switch 8, and the memory switch 9, the microcomputer 15 performs an operation necessary for selecting title information. This will be described in detail with reference to the flowchart of FIG.

FIG. 3 is a flowchart for explaining the operation of the main routine of the camera. First, when the power switch 3 is turned on, the microcomputer 15 is power-on reset and the operation is started. Then, in step S1, initialization of a register inside the microcomputer 15 or initialization of an I / O port is performed.

Next, in step S2, it is checked whether or not the external control device 30 is connected to the communication terminal 10. Here, when the external control device 30 is connected, the process shifts to step S3 to execute the test mode.

In the test mode, desired data can be stored in the EEPROM 20. Step S3
, The address of the EEPROM 20 is read from the communication terminal 10, and in the subsequent step S4, the EEPROM is read from the communication terminal 10.
Data recorded in ROM 20 is read. Then
In step S5, based on the address input in step S3 and the data input in step S4,
The operation of storing data in the EEPROM 20 is performed.

On the other hand, if the external control device 30 is not connected in step S2, the process proceeds to step S6, where the state of the switch connected to the microcomputer 15 is input.

In step S6, the scroll switch 7
It is determined whether or not there is a change in. Here, when a change is detected, the process proceeds to step S9. If there is no change, the process proceeds to step S7, and it is determined whether or not the set switch 8 has changed. When a change is detected, the process proceeds to step S9, and when there is no change, the process proceeds to step S8. Then, in this step S8, it is determined whether or not the memory switch 9 has changed. Here, if a change is detected, the process proceeds to step S9, but if there is no change, the process proceeds to step S10 to determine whether or not the release switch 4 has changed.

The scroll switch 7, the set switch 8, and the memory switch 9 are switches for selecting the title information. Therefore, when any one of these switches changes, it indicates that the user wants to select title information. Therefore, in this case, the process shifts to step S9 to execute the subroutine "title selection".

In step S10, when a change in the release switch 4 is detected, the process proceeds to step S11. In this step S11, the luminance information of the subject is input from the photometry circuit 18. Then, the shutter / aperture control circuit 19 is controlled according to the luminance of the subject, and the film 27 is exposed.

Next, in step S12, the film 2
7, data to be magnetically recorded is created. If a title desired by the user has been selected in the subroutine "title selection" in step S9, this data is also added as data to be magnetically recorded.

In step S13, the drive circuit 22 is controlled to wind the film 27 by one frame. Further, in parallel with this operation, the magnetic recording circuit 23 is controlled, and the data created in step S12 is magnetically recorded on the film 27.

Then, in step S14, the display circuit 1
When the title is displayed in step 7, the display is turned off. The title is displayed in the subroutine "Select Title" in step S9. The user turns on the display in conjunction with the selection of the title, and confirms that the display has been turned off after the winding of the film is completed, thereby knowing that the desired title has been magnetically recorded.

In step S15, the state of the power switch 3 is determined. If the power switch 3 is on, the process returns to step S6 to continue the operation.
If the power switch 3 is off, the operation of the microcomputer 15 is stopped.

Next, referring to the flowchart of FIG.
The operation of the subroutine "title selection" will be described. First, in step S21, data of "month" is read from the clock circuit 21. Next, in step S22, the data of "month" is read from the EEPROM 20 in correspondence with the address of the EEPROM 20.

FIG. 5 shows an example of a memory map of the EEPROM 20. In the example shown here, addresses 40h to 4Bh correspond to 1 to 12 of the "month" data.
The month is supported. If the data read in step S21 represents January, the EEPROM 20
The data read from is 8030h (*
0).

The memory map shown in FIG. 6 is a table of title data formed on the ROM 16 inside the microcomputer 15. In this table, a 16-byte memory is allocated to one piece of title information. The magnetic code is 1-byte data, and only this code is magnetically recorded on the film 27. The display data has 15 bytes, and one character corresponds to one byte. The microcomputer 15 controls the display circuit 17 based on the display data.

In step S23, the title information at the address 8030h corresponding to the data read from the EEPROM 20 is read (indicated by * 1 in the memory map in FIG. 6). The code magnetically recorded on the film 27 is “13”. Then, the title displayed on the display circuit 17 is "Ginger". This display is performed in step S24.

Next, the states of various switches are determined.
First, in step S26, the scroll switch 7
It is determined whether or not there is a change in. Here, if there is a change, the process proceeds to step S26, and if there is no change, the process proceeds to step S26.
Move to 31.

In step S26, the address of the table is incremented. Assuming that the table address is 8030h, the next table is 8040h.
h.

In step S27, it is determined whether the table address has been incremented beyond the bottom address. If the scroll switch 7 is continuously operated by the user, the address is finally changed to the bottom address (82
00h). In this case, the top address (8000h) must be set as the table address. This processing is performed in step S28.

In step S29, the title information corresponding to the incremented table address 8040h is read. Further, in step S30, display data is displayed.

FIG. 7 is a diagram showing how the title displayed by the display circuit 17 changes. For example, address 80
The display data "show" stored in 30h is displayed first. Here, if the title desired by the user is not “show”, the user operates the scroll switch 7 until the desired title is displayed. Then, the display is scrolled as shown in A → B → C →.

In step S31, a change in the set switch 8 is determined. Here, when a change is detected, the process proceeds to step S32, and when there is no change, the process proceeds to step S3.
Move to 3.

In step S32, a title code is read as magnetic data. The user looks at the “show ginger” first displayed on the display circuit 17 (display unit 6),
When it is determined that this title is sufficient, the set switch 8
Is operated. In this case, the magnetic code 13 (indicated by * 1 in FIG. 6) stored at the address 8030h is added as magnetic data. Then, the process returns to the main routine.

If it is determined in step S32 that the displayed "show" is not the desired title, the user operates the scroll switch 7 to continue the scroll display until the desired title is displayed. Is operated. In this case, the magnetic code stored in the table address at the time when the set switch 8 is operated is read as magnetic data.

In step S33, a change in the memory switch 9 is determined. If there is no change, the process returns to step S25. The memory switch 9 is an EEPROM
The switch is operated when changing the information of the table address stored in the table 20. As mentioned above, in January, the EE
The PROM 20 stores an address of 8030h.

However, some users may want to give priority to this title. For example, assume that the user wants to give priority to the title "Kekkon". In this case, the scroll switch 7 is operated until "OK" appears on the display. Then, the memory switch 9 is operated. Then, a table address 8080h (indicated by * 2 in FIG. 6) corresponding to the title "Kekkon" is recorded in 40h of the EEPROM 20. With this operation, when a title selection operation is performed in January, "Kekkon" is first displayed.

In this embodiment, when forming an EEPROM map, one year is divided into 12 and addresses are assigned to each month. However, the number of divisions need not be limited to twelve. Further, the map of the EEPROM may be formed in consideration of not only the information of “month” but also the information of “day”. By forming the map in this way, it is expected that the probability that the user will find the desired title in the first display is further improved.

Further, when a map that divides one year into 12 parts cannot be created due to a small number of EEPROM memories, for example, one year is divided into four parts and table addresses corresponding to January to March are stored. Table address corresponding to month, table address corresponding to July to September, 10 to 12
Only the table address corresponding to the month may be stored in the EEPROM.

In the above-described embodiment, only the Japanese title has been described. However, the present invention is not limited to this.
The title information can correspond to languages other than Japanese. In the case of languages other than Japanese, an EEPROM map corresponding to an annual event in a country where each language is used may be formed.
