Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to retinal stimulation in the field of books, posters, signboards, etc. that visually express a logical hierarchical structure of information units, inclusion relations, chapters, sections, items, etc. And a method and apparatus for recommending a typeface for each layer in order to configure a point font style of characters so as not to conflict with the viewpoint of customs understanding.

Here, "to be consistent with the viewpoint of retinal stimulation and the viewpoint of habit understanding" means that, from the viewpoint of retinal stimulation, the larger the difference in the conspicuousness depending on the size and thickness of the character, the chapter / section.・ It is easy to recognize the difference in the hierarchy such as paragraphs, but from the viewpoint of understanding customs, the structure of the document is part / chapter / section / item / eye / text /
Since there is a habit of using many layers such as Supplement 1 and Supplement 2, if you make the difference between the level directly above and below a certain level too large, the contrast for distinguishing these levels will be secured. It means that it is difficult to do.

[0003]

2. Description of the Related Art Conventionally, graphic designers who visually express characters such as books, posters, and billboards change the typeface such as character points, fonts, and styles to change the unit of information, inclusion relations, chapters, sections, and items. By visualizing the logical hierarchical structure such as, the effect of information searchability and comprehensibility is generated.

However, in order for the designer to realize the above visual expression, it is important now that the following two conditions are met.

(1) Knowing where and how much is emphasized in different expressions such as books, posters, and billboards.

(2) To have a sharp visual sensation that can be perceived as to whether or not the expression can be performed according to the knowledge.

[0007]

Therefore, when trying to realize a harmonious visual expression that a general person who is not a designer does, the above two conditions are not satisfied, and it is more difficult than a designer. There is a problem with it.

[0008] Specifically, with respect to the type of character style used in each logical layer that constitutes a chapter, section, item, etc. If there is too little difference in how to stand out due to the thickness and thickness, or if the viewer misunderstands the hierarchy, or if there is too little difference in how to stand out, it is not possible to secure the contrast for distinguishing many hierarchies. If the difference is not taken into consideration, there is a problem that the lower typeface becomes more conspicuous than the upper typeface, which causes an illusion in understanding information.

Conventionally, as tools for selecting a typeface, there are a typeface selection menu of a computer and a list of typefaces by books. However, since many typefaces are arranged side by side and no recommendation is made, these are to be selected according to the knowledge and sensitivity of the designer.

Therefore, even if there is knowledge and experience like a designer, in order to realize the expression according to the knowledge, it is necessary to spend a lot of time and repeat the trial production and evaluation to realize a harmonious expression. There is. Of course, if an ordinary person who is not a designer tries to express, there is a problem that it takes more time and effort than a designer.

An object of the present invention is to visually express a logical hierarchical structure such as a unit of information, an inclusion relation, a chapter, a section and an item in the visual expression of characters such as a book, a poster and a signboard. -To provide a method and apparatus for automatically recommending typefaces such as styles for each hierarchy.

[0012]

A method of recommending a typeface for each layer of the present invention is to accumulate typeface feature data of at least the character area, the character density, and the number of points of each typeface of a target character in the order of the character area. Among the all the typefaces in which the typeface characteristic data is accumulated in the typeface specifying step of designating one of the typefaces of the typeface characteristic accumulating means,
Thinning out lower-level typefaces whose character area is less than or equal to the specified font type, and then thinning out the typefaces whose point number is smaller than the specified typeface number among the typefaces left over in the previous process. Among the typefaces remaining in the process of, the character area difference from the character area of the designated typeface is thinned out below the threshold value corresponding to the character area of the designated typeface, among the typefaces left in the previous process Then, the character density is lower than the character density of the specified typeface, and the uppermost recommended typeface presentation stage in which the remaining typeface is presented to the user as the recommended typeface of the upper layer by thinning out the typefaces in random order. Among all the typefaces for which the typeface characteristic storage means has accumulated the typeface characteristic data, the upper-layer typefaces having a character area which is equal to or larger than the character area of the designated typeface are thinned out, and thereafter, remain in the immediately preceding process.

From the selected font input unit 13, the font number of the font selected by the slightly-difference-character-area-calculation determining unit 14 for determining the slightly-character-character-area calculation formula (in descending order of the character area, 1.
2, ..., 60) is input. The small difference character area calculation formula determination unit 14 reads the data of the character area of the typeface indicated by the typeface number input from the selected typeface input unit 13 from the typeface feature storage unit 12 and determines the difference in the character area with the typeface directly above or below. A small character area calculation formula (approximate formula) that represents as a function of the character area is calculated. The font designating unit 15 is a font feature accumulation unit 1.
One of the fonts in which the font feature data is accumulated is designated in 2, and the font number is input. Typeface recommended range designation part 1
No. 6 is for a lower layer whose character area is equal to or less than the character area of the specified typeface when obtaining the recommended typeface of the upper layer whose character area is greater than or equal to the character area of the typeface specified by the typeface specification unit 15. When thinning out a typeface to obtain a recommended typeface of a lower hierarchy whose character area is less than or equal to the character area of the specified typeface, thin out the upper layer typeface whose character area is greater than or equal to the character area of the designated typeface. As a result of the processing of the recommended typeface range determination unit 16, the character size determination unit 17 thins out the typefaces whose number of points is smaller than the number of points of the designated typeface, when obtaining the recommended typefaces of the upper hierarchy among the remaining typefaces. When obtaining recommended fonts in the lower hierarchy, fonts with a number of points greater than the specified number of points are thinned out. As a result of the processing of the character size determination unit 17, the close-up character area determination unit 18 determines that the character area difference from the character area of the designated typeface among the remaining typefaces is less than or equal to a threshold value corresponding to the character area of the designated typeface. Thin out the typeface. Here, the threshold value is calculated using the close-character-character-area calculation formula calculated by the close-character-character-area calculation formula determination unit 14. The character density determination unit 19 is a small difference character area determination unit 18.

Output to a personal computer, etc.

Here, the character is a font which allows a human to recognize it as a character by forming a lattice-shaped condom used in a computer or the like with pixels composed of black dots and white dots.

Next, the operation of this apparatus will be described.

First, the character area and character density of each typeface, which is the process before the user of the apparatus actually uses the apparatus, are calculated, stored in the typeface characteristic storage unit 12, and the close-in character area calculation is performed. The process of obtaining the formula will be described with reference to FIG.

First, the character area / character density calculator 11 calculates the character area of each typeface of the target character "A" as shown in FIG. 5 (step 21). As a method of calculating the character area, for example, when a black character is described on a white background, the number of pixels (Pixels) occupied by the black portion forming the character shape is used. In addition, the character area is in one typeface composed of size, style, etc.
It may be calculated for all the Japanese syllabary or all characters including Kanji, numbers, katakana, and alphabet in the same typeface. The character areas calculated in this way are accumulated in the typeface feature accumulating section 12 in descending order. FIG. 6 shows the typefaces of FIG. 5 arranged in order of character area.

Next, the character area / character density calculator 11 calculates the character density of each typeface of the character "A" (step 22). As a method of calculating the character density, for example, when a black character is written on a white background, only the black part of the character is detected in the rectangle (the rectangle circumscribing one character) whose sides are the top, bottom, right, and left edges of the character. Of the area occupied by. The character density may be calculated for all Japanese hiragana in the same typeface, or may be calculated for all characters including kanji, numbers, katakana, and alphabet in the same typeface. FIG. 7 shows the typefaces of FIG. 5 arranged in order of character density.

The data thus obtained for each typeface are arranged in the order of the character area and stored in the typeface characteristic storage unit 12, as shown in FIG.

Next, the user selects, for example, the following eight fonts from the fonts arranged in the order of the character areas shown in FIG. 6, and selects those font numbers (1 to 60) from the selected font input section 13: From (step 23).

Number of font style points Character area (1) Gothic standard 50 points 691 pixels (2) Gothic standard 30 points 246 pixels (3) Gothic standard 20 points 111 pixels (4) Gothic standard 16 points 70 pixels (5) Gothic standard 12 points 42 pixels (6) Mincho standard 12 points 39 pixels (7) Mincho standard 10 points 27 pixels (8) Mincho standard 6 points 20 pixels

Next, the slightly different character area calculation formula determination unit 14 determines the character area of the typeface having the input typeface number as the typeface characteristic storage unit 1.
The character area difference from the upper layer and the character area difference from the lower layer of the selected typeface are calculated (step 24). The result is as follows.

[0033]

Next, the close character area calculation formula determining unit 14
When the character area is plotted on the X axis and the difference in the area of the typeface is taken on the Y axis as the character area difference, the following points are obtained (step 25).

Assuming that (x, y) = (character area, character area difference from upper hierarchy), (1)-(2) (246, 445) (3) (111, 135) (4) (70, 41) (5) (42, 28) (6) (39, 3) (7) (27, 12) (8) (20, 7)

Assuming that (x, y) = (character area, character area difference from lower hierarchy), (1) (691, 445) (2) (246, 135) (3) (111, 41) (4 ) (70, 28) (5) (42, 3) (6) (39, 12) (7) (27, 7) (8) -FIG. 8 shows an example of the selected typeface and the difference in character area. There is.

Next, the close character area calculation formula determining unit 14
As shown in FIGS. 9A and 9B, when a quadratic equation is obtained by parabolic approximation of the above points (step 26), Y is obtained respectively.
= 0.006X ² + 0.395X, Y = 0.00031
58X ² + 0.427X is obtained, and the obtained expression is stored in the slightly different character area determination unit 18 (step 27).

Next, the operation of obtaining the recommended typeface of the target character "A" using this apparatus will be described with reference to FIGS.

First, the operation for obtaining the recommended typeface in the upper layer will be described with reference to FIG.

First, the user designates a typeface and inputs the typeface number from the typeface designating section 15 (step 31).

This typeface number is input to the typeface recommended range determination section 16 and the typeface characteristic data (character area, character density, number of points) stored in the typeface characteristic storage section 12 is read (step 32).

Assuming that the typeface number is j (1 ≦ j ≦ 60), the typeface recommended range determination unit 16 thins out the typefaces at the (j + 1) th and subsequent positions in the read typeface data. The range of recommended typefaces in the upper hierarchy is obtained, and the typeface number of the typeface is sent to the character size determination unit 17 (step 3
3).

The character size determining unit 17 thins out the recommended typefaces determined in step 33 from the typefaces having the points less than the points of the designated typefaces.
The range of recommended fonts in the upper layer is obtained, and the font number of the font is sent to the slightly different character area determination unit 18 (step 34).

The small character area determination unit 18 determines in step 34.
Character area Si (1 ≦ i ≦ m) of the recommended typeface determined by
Difference from character area X of the specified typeface di = Si-X
(1 ≦ i ≦ m) is calculated (step 35), Y = 0.00
The value of 6X ² + 0.395X is obtained (step 36), d
By thinning out the typefaces with i ≦ Y (1 ≦ i ≦ m),
The range of recommended fonts in the upper layer is obtained, and the font number of the font is sent to the character density determination unit 19 (step 37).

From the recommended fonts determined in step 37, the character density determination unit 19 thins out fonts whose character density is less than the specified character font density, and uses the remaining thinned fonts as recommended fonts in the upper layer, and uses them. Present to the person (step 3)
8).

Next, the operation of obtaining the recommended typeface of the lower hierarchy will be described with reference to FIG.

The recommended typeface range determining unit 16 thins out the typeface numbers 1 to (j-1) in the read typeface data to find the range of recommended typefaces in the lower hierarchy, The typeface number of the typeface is sent to the character size determination unit 17 (step 41).

The character size determination unit 17 determines the range of recommended fonts in the lower hierarchy by thinning out the fonts whose point number is larger than the point number of the specified font from the recommended fonts determined in step 41. The font number of the font is sent to the slightly different character area determination unit 18 (step 42).

The close character area determination unit 18 proceeds to step 42.
Character area Si (1 ≦ i ≦ m) of the recommended typeface determined by
Difference from the character area X of the designated typeface di = X-Si
(1 ≦ i ≦ p) is calculated (step 43), Y = 0.00
The value of 03158X ² + 0.427X is calculated (step 4
4), the range of recommended fonts in the lower hierarchy is obtained by thinning out fonts with di ≦ Y (1 ≦ i ≦ p), and the font number of the font is sent to the character density determination unit 19 (step 45).

The character density determination unit 19 thins out the recommended fonts determined in step 45 from the recommended fonts whose character density is smaller than the specified character font density, and sets the remaining thinned fonts as the recommended fonts in the lower layer, A series of processing is ended (step 46).

Next, a specific example of the process for obtaining the recommended typeface in this embodiment will be shown.

In the font designating section 15, for example, the number of points:
12 points, font: Mincho, style: standard, character area: 39 pixels, character density 35.45%, rank 42
If the typeface of the rank is designated (FIG. 10), the typeface data is read from the typeface characteristic storage unit 12, and the recommended typeface range determining unit 16 thins out the typefaces from the 43rd position to the 60th position, as shown in FIG. The typefaces from 1st to 41st are recommended typefaces in the upper hierarchy.

Next, in the character size determination unit 17, as shown in FIG. 12, the 38th and 39th typefaces, which are the typefaces with points smaller than 12 points, are thinned out, and the 1st to 37th positions and the 40th to 41th positions are reduced. The typefaces up to the rank are the recommended typefaces of the upper hierarchy.

Next, in the small difference character area determination unit 18, Y =
In the formula of 0.006X ² + 0.395X, 39 is substituted for X to obtain Y = 24.53, and the character area is 63.53 (= 39 + 24.53) pixels or less as shown in FIG. To 41st thinned out, 1st to 31st
The typefaces up to the rank are the recommended typefaces of the upper hierarchy.

Next, as shown in FIG. 14, the character density determination unit 19 thins out the fonts at the 5th, 14th, 17th and 22nd positions where the character density is less than 35.45%, and removes the remaining fonts. Use the recommended typeface for the upper hierarchy.

Next, in the recommended typeface range determining section 16,
As described above, the 1st to 41st typefaces are thinned out, and the 43rd to 60th typefaces are set as the recommended typefaces of the lower hierarchy.

Next, the character size determination unit 17 thins out the typeface having a number of points larger than 12 points. Since there is no corresponding typeface here, from the 43rd position to the 60th position as shown in FIG.
The typefaces up to the rank are the recommended typefaces of the lower hierarchy.

Then, in the small difference character area determination unit 18, Y =
0.0003158X ² + 0.427X, 3 for X
By substituting 9 for Y = 17.13, as shown in FIG.
Fonts from 43rd to 49th with a character area of 21.87 = (39-17.31) pixels or more are thinned to 50
The typefaces from the 60th place to the 60th place are the recommended typefaces of the lower hierarchy.

Next, in the character density determination unit 19, as shown in FIG. 18, the character density of 50th and 5th is higher than 35.45%.
Thinned out the typefaces from 2nd, 53rd, 55th to 58th,
The typeface remaining after thinning is set as a recommended typeface in the lower hierarchy, and a series of processing is ended.

The present invention is not limited to the above embodiment, and the recommended typefaces in the lower layer may be obtained earlier than the recommended typefaces in the upper layer. In addition, the character size determination unit 17,
The processing order of the slightly different character area determination unit 18 and the character density determination unit 19 is not limited to the above-described embodiment, but may be arbitrary. Further, the character area difference Y may be directly obtained from the character area data stored in the typeface feature storage unit 12.

When determining the recommended fonts for the lower layers that are less than or equal to the area, the font area recommended range determination means for thinning out the upper layer fonts whose character area is greater than or equal to the specified font area, and the result of the processing of the immediately preceding method remains. Among the typefaces, when seeking the recommended typeface for the upper layer, the number of points is thinned out, and when seeking the recommended typeface for the lower layer, the number of points is the number of points for the designated typeface. As a result of the processing of the character size determination means for thinning out a larger typeface and the immediately preceding means, the difference in character area between the character area of the designated typeface and the character area of the designated typeface among the remaining typefaces corresponds to the character area of the designated typeface. The character density is less than the specified character type when determining the upper-level recommended font type out of the remaining typefaces as a result of the processing of the small character area determination means that thins out the typefaces that are less than or equal to the threshold When decimating a character typeface that is a lower layer and obtaining a recommended typeface of a lower layer, the character density determining unit that decimates a typeface whose character density is greater than the character density of the specified character is included, Determination means,
The character density determination means is connected in series in any order after the typeface recommended range determination means, and the last means is the remaining typefaces as a result of thinning out, as a recommended typeface for the upper layer and a recommended typeface for the lower layer. A device that recommends a typeface for each layer to be presented to. 5. The character area and character density of each typeface are calculated,
The apparatus according to claim 4, further comprising a character area / character density calculation unit that is stored in the typeface feature storage unit. 6. At least 2 from the typeface feature storage means.
Select any one of the two fonts, check the character areas of these fonts, and for each font, the characters of that font and the characters of the fonts that are located directly above the selected font that is higher than the font. The area difference and the character area difference between the typeface and the typeface located directly below the typeface among the selected typefaces located in a hierarchy lower than the typeface are obtained, and the character area is calculated from the character area and the character area difference data. It further has a close character area calculation formula determining means for obtaining an approximate expression expressing a difference in character area, and the close character area determining means calculates the threshold value by substituting the character area of the designated typeface into the approximate expression. ,
The device according to claim 4 or 5.
