Abstract

Legibility of a character is enhanced by making the feature portion of a character distinguishable while ensuring a sufficient line space. In a character pattern generator (10), a regulation means (11) regulates the coordinate position of a reference line, i.e. an auxiliary line common to the arranging direction of at least one character, for indicating the feature of the profile of a reference character pattern, in the direction perpendicular to the arranging direction of at least one character in the objective reference character pattern based on reference line coordinate information indicating the feature of the profile of a character determined for each specified character size. For the coordinate position of a regulated reference line, a calculation means (12) moves or deforms the objective reference character pattern by performing coordinate calculation on each stroke constituting that character pattern.

 [0001] The present invention adjusts the coordinate position of the reference line representing the character's characteristic shape when displaying characters on the display screen, and deforms the character to correspond to the adjusted coordinate position of the reference line. Or a character pattern generation device that performs processing to be moved, a character display device (display device) such as a liquid crystal display or an organic EL display that uses this to generate character data as display data, and communication via a communication network Communication devices (communication devices), printing devices such as printers (printing devices), mobile phone devices and mobile information terminal devices (PDAs) such as mobile devices, television devices and other AV devices and personal computers Electronic information devices such as, character pattern generation programs for causing a computer to execute character data generation processing used in these devices, and this sentence A computer-readable readable recording medium on which a pattern producing formation program is recorded. Background art

 [0002] When character display is performed on a display screen in contrast to currently used mobile devices such as mobile phone devices and portable information terminal devices (PDAs), a character string drawing area The size of the display screen is limited. For example, in the case of a mobile phone device, the size of the display screen is about 4.5 cm x 3.4 cm. Nevertheless, since it is necessary to display as much information as possible on a single screen, the display screen of such a mopile device is compared to the initial setting value including the line spacing data on the display screen of a personal computer. The characters are displayed with some space between them. For example, in Windows (registered trademark) Notepad, the character height and the interval between the reference lines of the upper and lower adjacent lines, that is, the bottom line data of a certain character frame y_min The relationship between the line pitch that represents the width from the character line of the next line to the bottom line data y_min is 4: 4, and in mobile phones, the relationship between the character height and the line pitch is 4: 3.

[0003] Hereinafter, a conventional character display method generally used will be described with reference to FIG. explain.

 [0004] FIG. 21 is a display screen diagram showing an example of character display, in which (a) is a display screen diagram showing an example of a character pattern that is an original character before transformation, and (b) Figure (c) shows a case where the character point and line pitch of the character pattern are reduced by 30%. (C) shows 25 character pitches of the character pattern compared to (a). /. The line pitch is 5. /. (D) is a display screen diagram showing a case where the character height of the character pattern is reduced by 25% only in the vertical direction with respect to (a).

 [0005] As shown in Fig. 21 (b), the method of reducing the character points (number of dots) and line pitch of the character pattern increases the amount of information displayed on one screen, but the characters themselves are small. The problem of being difficult to read remains.

 [0006] As shown in FIG. 21 (c), in the method of reducing the character pitch and line pitch of the character pattern, the amount of information displayed on one screen is increased, but the amount of characters displayed within a certain range is reduced. Since it increases remarkably, the problem that the screen becomes complicated and difficult to read remains.

 [0007] As shown in Fig. 21 (d), when the character height of the character pattern is reduced by 25% only in the vertical direction, the line spacing appears to be free, so the screen becomes complicated and difficult to read as described above. The above problem seems to be solved. However, in the case of reduction only in the vertical direction, that is, in flat body processing, the entire character is uniformly reduced in the vertical direction, and there is a possibility that it may hinder the discrimination between characters having similar character shapes. Problems occur. For example, for characters “h” and “n” that are similar in shape, it can be said that the character feature (feature shape), which is the place to determine the difference between them, is the length of the left vertical bar. For this reason, as the vertical bar indicating the characteristic shape of “h” is shortened only in the vertical direction, the difference from “n” becomes less noticeable, and the letters “h” and “ It becomes difficult to instantaneously distinguish “n”.

[0008] For example, in Patent Document 1, the reference line is moved according to the reference width so that the quality of the character is maintained even when the character is enlarged / reduced, and the individual character is adjusted accordingly. A technique for adjusting the thickness of the character line width in one character is disclosed. According to this conventional technology, it is possible to always keep the thickness of the line segment of the character constant. Therefore, according to this prior art, it is possible to suppress a variation in line width within one character and generate a character pattern indicating a character with maintained quality. [0009] Patent Document 2 discloses a technique for enlarging / reducing a character according to conditions such as a P-contact character and then aligning it with a reference line (center line) so that the quality of the character is maintained. Yes. This prior art enables balance adjustment with surrounding characters. Therefore, according to this conventional technique, it is possible to generate a character pattern indicating characters with quality maintained while suppressing variations in character appearance size and being balanced with surrounding characters.

 [0010] Patent Document 3 describes a technique for correcting an optimal overshoot amount (the amount of protrusion from the reference line) based on the reference line position information on the character design so that the quality of the character is maintained. Is disclosed. With this conventional technology, it is possible to adjust the balance with surrounding characters while making a specific character to be deformed. Therefore, according to this conventional technique, it is possible to generate a character pattern that indicates characters that maintain quality by suppressing variations in the appearance size of characters and maintaining balance with surrounding characters.

 Patent Document 4 discloses a technique for calculating a character height in accordance with a drawing area and automatically correcting a character string in accordance with a calculation result so that the quality of the character is maintained. With this conventional technique, it is always possible to output a character pattern in the drawing area. Therefore, according to this prior art, it is possible to prevent a character from being output beyond a predetermined area, and to generate a character pattern indicating a character with maintained quality.

 Problems to be solved by the invention

[0012] It is said that when a human eye discriminates a character, what is being watched is, for example, a silhouette of the character such as unevenness of the outline of the character. This is because the character silhouette is likely to show a difference from other similar characters, and represents the character's feature (feature shape). For a single character, circle the circle about 10% from the center of gravity where the top and bottom balance of the character is equal and the center where the left and right balance of the character is equal. It is from this action that you can imagine what the character is even if you hide the central part of the character as you draw. It should be noted that the ratio varies depending on the characteristics of the characters, such as Japanese and European, and this is not mentioned here.

 [0013] Therefore, it can be said that the easier the character feature portion is captured, the faster the reader's character discrimination 'word comprehension' sentence reading comprehension can be prevented and misreading can be prevented. Sufficient white space or sufficient space around each displayed character is necessary to grasp the character's characteristic part.

 [0014] Further, the screen size is small and the number of characters displayed on one line is small. This means that when the line of sight moves from the end of the line to the beginning of the next line, the eyeball slides frequently. In such a case, if the line spacing is narrow, it may be difficult to express or distinguish the character feature part that is not a force if misreading such as transfer and duplicate reading increases.

 [0015] The format of easy-to-read text is something that does not interfere with the act of concentrating on the content. Therefore, the readability of the text is thought to depend on how to ensure sufficient line spacing and make it easy to distinguish the character part.

 [0016] According to the prior art disclosed in Patent Document 1, it is possible to obtain a certain character quality by keeping the thickness of a line segment of each character constant. is there . However, this conventional technology did not contribute to the readability of the whole sentence without the effect of ensuring sufficient line spacing and making it easy to distinguish the character features.

 [0017] According to the prior art disclosed in Patent Document 2, it is possible to obtain a certain character string quality by suppressing variations in the appearance size of characters for each character. . However, this conventional technique does not contribute to the readability of the whole sentence without the effect of ensuring sufficient line spacing and making it easy to distinguish character features.

[0018] According to the conventional technique disclosed in Patent Document 3, it is possible to adjust the balance with surrounding characters while using a character string as a target and changing a specific character as a deformation target. The appearance size and the line spacing appear. However, this conventional technology does not have a working effect that ensures sufficient line spacing or makes it easy to distinguish character features. It did not contribute to the readability of the entire chapter.

 According to the conventional technique disclosed in Patent Document 4, it is possible to always output a character pattern in the drawing area by calculating the character height for a character string. However, this conventional technology does not contribute to the readability of the whole sentence, such as ensuring sufficient line spacing or distinguishing character features.

[0020] The prior arts of the above-mentioned patent documents:! To 4 make it easy to distinguish character feature parts while ensuring sufficient line spacing, whether they are single or combined, and make text visible. It is not possible to improve readability.

 [0021] The present invention solves the above-mentioned conventional problems, and makes it easy to distinguish character features while ensuring sufficient line spacing, thereby improving character readability. It is an object of the present invention to provide a character pattern generation program for causing a computer to execute character data generation processing used therefor, and a computer-readable readable recording medium on which the program is recorded.

The reference position information common to the direction in which the characters are arranged is displayed in such a way that the feature shape is more visible, i.e., the character with a larger dimension of the different character shape is easier to distinguish (if the character size is reduced) The feature shape is also reduced in the same way, but the adjustment means so that the proportion of the feature shape in the entire character after the reduction becomes larger than the proportion of the feature shape in the whole character before the reduction). And the reference position information adjusted by the adjusting means In order to correspond to the information, it has calculation means for calculating or moving or transforming the position of at least one of the strokes constituting the reference character pattern, thereby achieving the above object. Is done. As described above, the adjustment that makes the characteristic shape appear more is an adjustment that makes it easier to discriminate characters that have larger sizes before and after the deformation process. In other words, the adjustment that expresses the feature shape force means that when the character size is reduced, the ratio of the feature shape to the whole character after reduction is the feature shape that occupies the whole character before reduction. The adjustment will be larger than the ratio.

 [0024] The reference position information represents a reference coordinate position. For example, in the case of characters such as alphabets, the coordinate position of the baseline when laying out the characters corresponds to the reference position information.

 [0025] The reference position includes a reference line for controlling a two-dimensional figure and a reference plane for controlling a three-dimensional figure.

 In FIG. 3, for example, in the letter “h”, the first fixed reference line 423A-1, the first movable reference line 423B-1, the second movable reference line 423B-2, the second fixed reference line 423A-2, First fixed reference line 423A—Spacing A between 1 and first movable reference line 423B—1, A First movable reference line 423B—Spacing B between 1 and second movable reference line 423B—Second B movable reference line 423B — The distance C between 2 and the second fixed reference line 42 3A-2 is shown. Here, the difference in shape between the letter “h” and the similar letter “n” is the presence or absence of a long vertical stroke, and the size of the spacing A affects the degree to which the character feature shape appears. Therefore, by changing the position of the first movable reference line 423B-1, which defines the interval A, the ratio of the long and vertical strokes, which are the character's characteristic shapes, to the entire character increases. As a result, the character feature shape becomes more prominent.

[0083] First fixed reference line 423A-1 indicates the maximum coordinate position of a character in a direction perpendicular to the character string direction among a plurality of reference lines. For example, in the case of the alphabet (alphabet), since the direction of the character string is the X direction, the maximum coordinate position (y−max) in the Y direction, which is the direction perpendicular to the X direction, is indicated. For example, in the case of Japanese text (kanji / kana) in vertical composition (vertical writing), since the direction of the character string is the Y direction, the maximum coordinate position in the X direction (X— max). Similarly, the second fixed reference line 423A— 2 shows the minimum coordinate position of a character in a direction perpendicular to the character string direction among a plurality of reference lines. For example, in the case of the alphabet (alphabet), the direction of the character string is the X direction, so the minimum coordinate position (y_min) in the Y direction, which is the direction perpendicular to the X direction, is indicated. For example, in the case of Japanese text (kanji / kana) in vertical composition (vertical writing), the direction of the character string is in the Y direction, so the minimum coordinate position in the X direction that is perpendicular to the Y direction (x_min) Is shown.

 [0084] The first movable reference line 423B-1 and the second movable reference line 423B-2 exist between the first fixed reference line 423A-1 and the second fixed reference line 423A-2, and the number and direction thereof are May vary by language and typeface. In the first movable reference line 423B-1 and the second movable reference line 423B-2, the coordinate position in the direction perpendicular to the character string direction is variable for each character size and is adjusted by the adjusting means 11. The

 [0085] The first movable reference line 423B-1 and the second movable reference line 423B-2 are not in contact with each other and are independent. In addition, the first fixed reference line 423A-1 and the second fixed reference line 423A- There may be cases where neither of them touches. Movement of movable reference lines such as the first movable reference line 423B—1 and the second movable reference line 423B—2 is all within the range of the first fixed reference line 423A—1 and the second fixed reference line 423A—2. Done.

 [0086] The interval A is the coordinate distance from the first fixed reference line 423A-1 to the first movable reference line 423B-1 and the interval B is the first movable reference line 423B-1 to the second movable reference line 423B-2. The distance C is the distance from the second movable reference line 423B-2 to the second fixed reference line 423A-2. For example, in the alphabet (alphabet), the first fixed reference line 423A-1 is the ascender line, the first movable reference line 423B-1 is the X height, the second movable reference line 423B-2 is the base line, and the second fixed reference line. 423A-2 is a descender line.

 FIG. 25 is a diagram for explaining the basic concept of the reference plane by applying FIG.

 In FIG. 25, for example, in the letter “hn”, the first fixed reference plane 25-1, the first movable reference plane 25-2, the second movable reference plane 25-3, and the second fixed reference plane 25-4 are indicated. Show.

[0089] The first fixed reference plane 25-1 indicates the maximum coordinate position of a character in a direction perpendicular to the direction in which at least one character is arranged among a plurality of reference planes. Similarly, the second fixed reference surface 25-4 is in the direction in which at least one character is arranged among a plurality of reference surfaces. The minimum coordinate position of the character in the vertical direction is shown.

[0090] The first movable reference plane 25-2 and the second movable reference plane 25-3 exist between the first fixed reference plane 25-1 and the second fixed reference plane 25_4, and the number and direction thereof are May vary by language and typeface. In the first movable reference plane 25-2 and the second movable reference plane 25-3, the coordinate position in the direction perpendicular to the character string direction is variable for each character size and is adjusted by the adjusting means 11. .

 [0091] The first movable reference surface 25-2 and the second movable reference surface 25-3 are not in contact with each other and are independent, and further, the first fixed reference surface 25-1 and the second movable reference surface 25- In some cases, 3 may not touch. Movement of movable reference lines such as the first movable reference line 423B-1 and the second movable reference plane 25-3 is all within the range of the first fixed reference plane 25-1 and the second fixed reference plane 25-4. Only done.

 FIG. 23 is a diagram for explaining a reference line when the line is not a straight line.

 [0093] In FIG. 23, for example, in the letter “hnvy”, the first fixed reference line 23-1, the first movable reference line 23-2, the second movable reference line 23-3, and the second fixed reference line 23-4. Is shown. In this case, since the reference lines are generated by maintaining a predetermined ratio, it is possible to maintain the character shape characteristics.

 [0094] The first movable reference line 23-1 and the second movable reference line 23-2 are not in contact with each other and are independent, and further, the first fixed reference line 23-1 and the second fixed reference line 23- In some cases, 4 may not touch. Movement of movable reference lines such as the first movable reference line 23-2 and the second movable reference line 23-3 is all within the range of the first fixed reference line 23-1 and the second fixed reference line 23-4. Done.

 [0095] FIG. 24 is a diagram for describing a reference line when the lines are not parallel to each other. Here, the case where the distance between the reference lines from the start point to the end point becomes narrower continuously is shown. Of course, the converse is also possible in which the distance between the reference lines of each reference line increases continuously from the start point to the end point.

 [0096] In FIG. 24, for example, in the character “hnvy”, the first fixed reference line 24_1, the first movable reference line 24-2, the second movable reference line 24-3, and the second fixed reference line 24-4 are represented. Show. In this case, since the reference line is generated by moving the ratio between the reference lines step by step from the start point to the end point of the character string, it is possible to maintain the character shape characteristics.

[0097] The first movable reference line 24-1 and the second movable reference line 24-2 are not in contact with each other and are independent. In addition, the first fixed reference line 24-1 and the second fixed reference line 24-4 may not contact each other. Movement of movable reference lines such as the first movable reference line 24-2 and the second movable reference line 24-3 is all within the range of the first fixed reference line 24-1 and the second fixed reference line 24-4. Done.

Here, with the above configuration, the operation executed by the control device 1 of the character pattern generation device 10 of the present embodiment based on the character pattern generation program of the present embodiment will be described below with reference to FIG. The details of the process will be explained for each step using the flowchart.

As shown in FIG. 4, as described above, first, in step S1, designated character code, character size, and other various information are input from the input device 2. In step S2, the character information corresponding to the character code is called from the font data table 42. In step S3, referring to the font data table 42, the character pattern corresponding to the entered character code is obtained from the character code 421, the character size information is obtained from the header information 422, and the typeface information is obtained from the font design 425. From each of them, and take out the reference character pattern 41.

 [0100] Next, in step S4, the adjustment means 11 generates a reference line with the force S applied to the character pattern generation program 43.

 With respect to the reference line generation procedure executed in step S4, details of the process will be described for each step with reference to the flowchart of FIG.

 [0102] As shown in FIG. 5, first, in step S41, the reference character pattern 41 extracted according to the designated character code is converted into the first fixed reference line 423A-1 and the second fixed reference of the reference line coordinate information 423C. Match line 423A-2. For example, in the case of European (alphabet) letters, the Y coordinate values of both ascender lines and descender lines should be aligned at the same height. Since the text size itself is the same, it is possible to align the Y coordinate values of the fixed reference line. Only the position of the movable reference line (for example, the first movable reference line 423B-1 and the second movable reference line 423B-2) may have different Y coordinate values.

 FIG. 6 shows an example in which the fixed reference line Y-coordinate values are aligned as a result of the processing in step S41.

[0104] As shown in Fig. 6, the first movable reference line 423B-1 of the reference character pattern 41, the reference line coordinates Information 1st movable reference line 423B—1 'read from 423C, 2nd movable reference line 423B-2 of reference character pattern 41, 2nd movable reference line 4 23B—2' read from reference line coordinate information 423C is there.

 Next, in step S42, the character pattern generation program for the movable reference line (corresponding to the movable reference line) among the reference lines of the reference character pattern 41 extracted according to the designated character size. Use 43 to move the Y coordinate value so that it matches the movable reference line in the reference line coordinate information 423C.

 [0106] For example, in the case of European (alphabet) characters, the X height of the reference character pattern 41 and the Y coordinate value of the base line are aligned to the same height as the reference line coordinate information 423C.

 As shown in FIG. 6, the first movable reference line 423B-1 is moved to the Y coordinate value of the reference line coordinate information 423C and aligned with the position of the first movable reference line 423B-1 ′. Further, the second movable reference line 423B-2 is also moved to the Y coordinate value of the reference line coordinate information 423C and aligned with the position of the second movable reference line 423B-2 ′. For example, in the case of the alphabet (alphabet), the first movable reference line 423B-1 is the X height before movement, the first movable reference line 423B-1 'is the X height after movement, and the second movable reference line 423B-2 is Baseline before movement, second movable reference line 423B-2 'is the baseline after movement.

 [0108] Next, in step S43, the adjustment means 11 is used to recognize the fixed reference line and the movable reference line whose coordinate value has been moved in step S42 as a new reference line. .

 In step S5 of FIG. 4, the position of the strokes constituting the character pattern is moved or deformed by the calculation means 12 according to the character pattern generation program 43 with respect to the reference line thus adjusted. I do.

 [0110] With regard to the character transformation procedure executed in step S5, details of the process will be described for each step with reference to the flowchart of FIG.

[0111] As shown in FIG. 7, first, in step S52, it is determined whether or not it is necessary to break down characters into strokes for each character according to the character pattern generation program 43. This is a decision process that is necessary for the subsequent processing to disassemble the character pattern into strokes and move or transform it. Characters that do not need to be decomposed into strokes to simplify and speed up the processing. With regard to the It has been the target. For example, in the case of the alphabet (alphabet), “o” and “c”, which have only one stroke, are examples of characters that do not need to be broken down into strokes.

[0112] Next, in the determination result in step S52, when characters need to be broken down into strokes (

If YES, the processing after step S53 is performed, and if it is not necessary to disassemble the character into strokes (NO), the processing after step S54 is performed.

[0113] In step S53, according to the character pattern generation program 43, the character is decomposed for each stroke.

 [0114] With regard to the character decomposition procedure executed in step S53, details of the process will be described for each step with reference to the flowchart of FIG. When processing is started, the coordinates of (X, y) shall start from (0, 0), which is the minimum value.

As shown in FIG. 8, first, in step S531, the end points of the stroke as shown in FIG. 3 are scanned in the horizontal direction from the minimum value of X to the maximum value.

[0116] Next, in step S532, whether or not the stroke information flag 424A in the flag information 424 is added to the line segment including the end point found in accordance with the character pattern generation program 43. Determine.

[0117] If the stroke information flag 424A is attached in the determination result in step S532 (YES), the process in step S534 is performed and the stroke information flag 424A is not attached (NO). In step S533 and subsequent steps.

In step S533, the stroke information flag 424A in the flag information 424 is attached to the line segment including the found end point. As a result, the line segments including the end points found are broken down as strokes and treated individually.

[0119] In step S534, according to the character pattern generation program 43, whether or not the current X coordinate value scanning the end point in the horizontal direction from the minimum value of X to the maximum value is equal to the maximum value. Determine.

[0120] If the result of determination in step S534 is that the current X coordinate value is equal to the maximum value (YES)

If step S535 is processed and the current X coordinate value is not equal to the maximum value (N

) Returns to the processing after step S531, and repeats until it becomes equal to the maximum value.

[0121] In step S535, according to the character pattern generation program 43, from the minimum value of X to the maximum Determines whether the current Y coordinate value, which is scanning the end point in the horizontal direction toward the maximum value, is equal to the maximum value.

 [0122] As a result of the determination in step S535, if the current coordinate value of Υ is equal to the maximum value (YES), the process ends. If the current coordinate value of Y is not equal to the maximum value (NO), Step S5 36 and subsequent steps are performed.

 [0123] In step S536, the coordinate value of the current X that is scanning the end point in the horizontal direction from the minimum value of X to the maximum value is returned to the minimum value, and the Y coordinate value is incremented by one.

 [0124] FIG. 9 shows an example of characters that are decomposed into strokes as a result of step S53.

 In FIG. 9, for example, the letter “h” is divided into a stroke T1 and a stroke T2.

 Of these, stroke T1 is represented by endpoints 1-1 and 1-2. Stroke 2 is represented by end points 2-1, 2, 2, 2-3, 2-4, 2-5, 2-6 and 2-7. The contact point information flag 424B in the flag information 424 is attached to the end point 2-1 that is in contact with the stroke T1.

 Returning to the processing of FIG. 7, in step S54, according to the character pattern generation program 43, the strokes are independently moved or deformed with respect to the newly generated reference line.

 [0127] The process of step S54 will be described in detail with reference to FIG.

 [0132] According to FIG. 11, when the character pattern has 8 points, the value of interval A is 72, the value of interval B is 104, and the value of interval C is 80. If the character pattern has 9 points, the value of interval A is 70, the value of interval B is 106, and the value of interval C is 80. Furthermore, if the character pattern has 10 points, the value of interval A is 69, the value of interval B is 108, and the value of interval C is 79. Furthermore, if the character pattern has 11 points, the value of space A is 67, the value of space B is 110, and the value of space C is 79. Furthermore, when the point force of the character pattern is 2 points, the value of interval A is 66, the value of interval B is 112, and the value of interval C is 78. These values are always referenced when calling the reference character pattern 41.

 On the other hand, FIG. 10 (c) shows a reference character pattern 41 which is arranged within a frame of 256 pixels × 256 pixels and is moved or deformed with respect to the reference line generated according to the reference line coordinate information 423C. The numbers in () indicate the coordinate values of each point.

 FIG. 10D shows a list of the coordinate values in FIG. 10C according to FIG.

 [0135] According to Fig. 10 (d), the coordinates of end point 1-1 of stroke T1 are X = 88 and Y = 80, and the coordinates of end point 1-2 of stroke T1 are Χ = 88, Υ = 227 It is. Also, the coordinates of end point 21 of stroke Τ2 are Χ = 88 and Υ = 141, the coordinates of end point 2-2 of stroke Τ2 are Χ = 104, Υ = 172, and the coordinates of end point 2-3 of stroke Τ2 Is Χ = 128, Υ = 184, the coordinates of end point 2-4 of stroke Τ2 are Χ = 152, Υ = 184, and the coordinates of end point 2-5 of stroke Τ2 are Χ = 176, Χ = The coordinates of end point 2-6 of stroke Τ2 are Χ = 184 and Υ = 160, and the coordinates of end point 2-7 of stroke Τ2 are Χ = 184 and Υ = 80.

 For example, in FIG. 10 (a), the first movable reference line is called Y2, the second movable reference line is called Yl, the end point 1-1 in FIG. 9 is called yl, and the end point 1-2 is called y2, In Fig. 10 (c), if the first movable reference line is called Y2 ', the second movable reference line is called Y1', the endpoint 1_1 in Fig. 9 is called yl ', and the endpoint 1_2 is called y2' The coordinate value of y2 'after character transformation is

 y2 '= Y1, + (y2-Yl) X (Υ2' _Υ1,) / (Y2—Y1)

 Sought by. If a decimal point occurs in the solution, round off to the first decimal place and always display the result as an integer.

In step S55 of FIG. 7, the contact information flag 424 情報 in the flag information 424 is referred to. [0138] In step S56, according to the character pattern generation program 43, the stroke of the character is synthesized using the contact information flag 424B referred to.

 In step S57, whether or not the correction information flag 424C is added to the stroke is determined according to the character pattern generation program 43.

 [0140] If the correction information flag 424C is added as a result of the determination in step S57 (YES), the process of step S58 is performed. If the correction information flag 424C is not added (NO), the character The transformation process ends.

 [0141] In step S58, according to the character pattern generation program 43, a common correction process applied to many characters is applied only to a specific character for characters to which the correction information flag 4 24C is added. The correction is performed using either the individual correction process or the correction process combining the common and individual.

 [0142] For example, when the process from step S52 to step S56 is performed for the letter "i", the ratio of the coordinate values between the point part and the bar part may not match that before the process. This is because the object to be processed is limited to the bar portion, and the moving direction of the coordinate values is not always constant. For this reason, in step S58, it is necessary to perform individual correction processing so that the ratio of the coordinate values of the point portion and the bar portion is always kept constant. In addition, for the character “y”, when the processing from step S52 to step S56 is performed, the intersection of the two line segments may not intersect on the line. This is because the processing ratio of each line segment is different and the moving direction of the coordinate values is not always constant. For this reason, in step S58, it is necessary to perform individual correction processing so that the intersections intersect on the line. Since these correction processes are not the main components of the present invention, a detailed description thereof is omitted here. In the above description, for simplification of the processing, the case where the strokes constituting the character are disassembled, the deformation processing is performed on the coordinate points of each stroke, and the strokes are synthesized later is described. It is also possible to select the coordinate points to be deformed based on the relative position with the coordinate point of the stroke using the coordinate position of the reference line as a threshold value, and perform the deformation process in batches in a batch. .

Returning to the description of the processing in FIG. 4, in step S6, the output device 3 displays the deformed character as output. In the following, details of the processing for each step will be described for another example of the reference line generation procedure executed in step S4 of FIG. 4 using the flowchart of FIG.

 [0143] As shown in FIG. 12, first, in step S61, as in step S41 of FIG. 5, the reference character pattern 41 extracted according to the specified character code is stored in the reference line coordinate information 423C. Match 1 fixed reference line 423A-1 and 2nd fixed reference line 423A-2.

 FIG. 13 shows an example in which the Y coordinate values of the fixed reference line are aligned as a result of the processing in step S61.

 As shown in FIG. 13, the first movable reference line 423B-1 of the reference character pattern 41, the first movable reference line 423B-1 ′ read from the reference line coordinate information 423C, and the first of the reference character pattern 41 2Moveable reference line 423B-2, Reference line coordinate information It is the second movable reference line 4238-2 'read from 423C.

 [0146] Next, in step S62, among the reference lines of the reference character pattern 41 extracted according to the designated character size, the coordinate position of the original movable reference line is left as it is for the movable reference line. , Generate a new movable reference line at the coordinate position of the reference line coordinate information 423C

[0147] For example, in the case of the alphabet (alphabet), a new X-hite and baseline are set at the position corresponding to the Y coordinate value of the reference line coordinate information 423C, that is, the position equal to the Y coordinate value of the reference line coordinate information 423C. Is generated.

 [0148] The Y coordinate value of the first movable reference line 423B-1 is left as it is, and the first movable reference line 423 B-1 is newly generated to correspond to the coordinate position of the reference line coordinate information 423C. The Further, the Y coordinate value of the second movable reference line 423B-2 is left as it is, and the second movable reference line 4 23B-2 ′ is newly generated so as to correspond to the coordinate position of the reference line coordinate information 423C.

[0149] For example, in the case of the alphabet (alphabet), the first movable reference line 423B-1 is newly generated at the original X height, and the first movable reference line 423B-1 'is newly generated at the coordinate position of the reference line coordinate information 423C. X Height, the second movable reference line 423B-2 is the original baseline, and the second movable reference line 423B-2 'is the newly generated baseline.

[0150] Next, in step S63, using adjustment means 11, a fixed reference line is generated in step S62. The formed movable reference line is recognized as a new reference line.

[0151] Here, FIG. 14 shows another example of deformation processing for a character that has been broken down into strokes in response to the processing result of step S53 in FIG.

[0152] As shown in FIG. 14, for example, the characters "rest" and "U" are divided from stroke T1 to stroke T6. Of these, stroke T1 is represented by endpoints 1-1 and 1-2. Stroke T2 is represented by end points 2-1 and 2-2. In addition, stroke T3 is represented by endpoints 3-1 and 3-2. In addition, stroke T4 is represented by endpoints 4-1 and 4-2. Furthermore, the strike T5 is represented by endpoints 5-1 and 5-2. In addition, stroke T6 is represented by endpoints 6-1 and 6-2. The contact point information flag 424B in the flag information 424 is attached to the end point 1-2 in contact with the stroke T5. Further, the contact point information flag 424B in the flag information 424 is attached to the end points 3-2 and 4-2 that are in contact with the stroke T2 and the stroke T6.

 [0161] Hereinafter, the operational effects obtained when the character pattern generation processing is performed by the character pattern generation device 10 of the present embodiment will be described with reference to FIG.

 [0162] Fig. 16 (a) is a full-scale model of a display screen of a general mobile phone device currently used.

 FIG. 16B shows an example in which character pattern generation processing is performed by the character pattern generation device 10 of the present embodiment. Compared to Figure 16 (a), the X-height ratio is 90%, and the apparent line spacing is increased by 10%.

FIG. 16 (c) shows another example in which the character pattern generation process is performed by the character pattern generation device 10 of the present embodiment. Compared to Figure 16 (a), the X-height ratio is 80%. The apparent line spacing has increased by 20%.

 [0165] The ratio of the X height and the increase between the apparent lines shown in FIG. 16 can be arbitrarily selected by the user setting the reference line coordinate information 423C. An example of an interface screen when the user makes this selection will be described with reference to FIG. Here, a case where the user can select and set the good reference line coordinate information 423C is shown, but this is not limiting, and the final manager may select and adjust the good reference line coordinate information 423C at the time of product shipment. Or, in addition to this, the user can select and adjust the good reference line coordinate information 423C.

 FIG. 17 is a full-scale model of a display screen of a general mobile phone device currently used, as in FIG. The upper, middle, and lower three levels show the same character display as in FIGS. 16 (a), 16 (b), and 16 (c), respectively. Fig. 17 shows that the X-height 90% (Fig. 16 (b)) in the middle row is selected.

 [0167] In this way, the user can freely select a plurality of X-height height candidates that suits his / her preference. Alternatively, the user may be able to enter a numerical value for the height of the X height.

 [0168] As described above, according to the present embodiment, the coordinate position of the reference line is adjusted based on the reference line coordinate information 423C representing the character feature shape determined for each character size, and the target reference character pattern In the direction perpendicular to the character string direction, move the character coordinate values up or down by the same value, or perform a transformation that increases or decreases different values for each character coordinate value. It is possible to output the same amount of text as before the transformation without changing the 'character spacing', and it is possible to secure a sufficient apparent space between the long and flat body processing.

 [0169] Here, the effects obtained as a result of using the present invention will be described in more detail with reference to Figs.

FIG. 18 (a) shows a state where the present invention is not used. The ratio of interval A and interval C in Fig. 18 (a) is always constant regardless of the character display size. For example, when the character size is reduced, the character feature (characteristic shape; `` H '' and `` n '' have a smaller interval `` v '' and `` y '' have a smaller interval C), such as `` h '' and `` n '', `` v '' and `` y '', etc. There was a problem that it was difficult to discriminate characters.

 [0171] FIG. 18 (b) shows a state in which the present invention is used. Since the ratio of interval A and interval C in Fig. 18 (b) is variable depending on the character display size, for example, when reducing the character size, the ratio of interval B can be adjusted by adjusting the ratio of interval B. Characteristic parts of both characters are emphasized, and as a result, the discrimination is easy.

 [0172] In order to specifically show the difference between the effects of Fig. 18 (a) and Fig. 18 (b), a description will be given using Fig. 19 (a) and Fig. 19 (b). The lOpt (point) characters enclosed in dotted lines are examples of sizes that are typically used on the mail screen of mobile phone devices.

 [0173] In FIG. 19 (a), the character size is displayed every 4pt from 6pt to 22pt without using the present invention. The ratio of interval B is constant regardless of the character display size. FIG. 19 (b) shows a state where the character size is displayed every 4pt from 6pt to 22pt using the present invention. Since the ratio of interval B is changed for each character display size, it is easier to distinguish between `` h '' and `` n '' and `` v '' and `` y '' than in the case of Fig. 19 (a). I understand the power S.

 The details of the reference line coordinate information 423C will be described with reference to FIG. 20, regarding the ratio of the spacing B that differs for each character display size in FIG. 19 (b).

[0175] Fig. 20 shows that the interval B in Fig. 18 (a) in a state where the present invention is not used is 100%, while the interval B in Fig. 18 (b) in the state where the present invention is used. This is a graph showing the ratio.

 [0176] As shown in FIG. 20, when displaying the letter lOpt as the display size, for example, the optimum value of the interval B when the present invention is used is the same as the interval B when the present invention is not used. 85%, and the optimum width is 80-90%. The optimum value of the character display size and the interval B is proportional, and after 22pt, the same value is used when the invention is not used and when it is used. Alternatively, the ratio of the interval B when the present invention is not used may exceed the ratio of the interval B when the present invention is used.

[0177] In addition, by moving or transforming the character for each stroke, the character features that help character recognition are emphasized, and the speed of word comprehension of the reader's reading and reading is improved. As a result, the legibility of the text can be improved. [0178] Further, when the character is moved or deformed, the user can select and set the reference line coordinate information 423C to display the character according to each user's preference.

 In the above embodiment, “h” and “n”, “v” and “y” are shown as English characters having similar feature parts (feature shapes). There are also “a” and “d”, “p”, “q” and “o”.

 [0180] Further, although not specifically described in the above embodiment, the point is that an adjustment unit that adjusts the reference position of the reference character pattern with respect to the target reference character pattern, and an adjustment by this adjustment unit. If there is a calculation means for moving or transforming the stroke by changing the coordinate position of at least one of the strokes constituting the reference character pattern by a predetermined calculation so as to correspond to the reference position set Thus, it is possible to achieve the object of the present invention, which makes it possible to more easily distinguish character features while ensuring sufficient line spacing and to improve the legibility of characters. In this case, the adjusting means adjusts the reference position for representing the feature shape of the reference character pattern so that the feature shape can be expressed more. That is, the reference position of the reference character pattern is set in advance so that the characteristic shape of the reference character pattern appears more for each character size. With reference to each set reference position (reference position information determined for each character size), a reference position corresponding to the target reference character pattern is obtained from the reference position information. This is because the reference position of the reference character pattern is adjusted by the adjusting means when the target reference character pattern is changed to the specified character size, but the change to the specified character size is the same character size. It also includes a transformation to In short, the input character information is either displayed, printed, or communicated so that the character features can be more easily identified while ensuring sufficient line spacing.

 [0181] The adjustment that makes the characteristic shape appear more is an adjustment that makes it easier to discriminate characters that have larger sizes before and after the deformation process. In other words, the adjustment that makes the feature shape appear more is that when the character size is reduced, the ratio of the feature shape to the entire character after reduction is the feature that occupies the whole character before reduction. The adjustment is such that it becomes larger than the shape ratio.

[0182] Here, the characteristic configuration of the present invention will be described repeatedly, but it represents the characteristic shape of a character. Using the auxiliary line common to the character string as the reference line, it is perpendicular to the character string of the target reference character pattern based on the reference line coordinate information representing the character feature shape defined for each specified character size. The coordinate position of the reference line is adjusted so that the feature shape appears more clearly in the correct direction, and the character pattern is coordinated and moved or deformed for each stroke according to the adjusted reference line. Unlike simple long / solid processing, the character size, character spacing, and line spacing do not change while ensuring the apparent line spacing, and the same document amount (information amount) as before transformation is displayed, printed, or printed. Communication output is possible.

[0183] Thus, the present invention uses the definition of the character shape based on the skeleton, and there is no need to adjust the line width by deformation as in the prior art. Further, according to the present invention, each part of the character shape sandwiched between a plurality of reference lines is deformed by enlarging or reducing it, so that it is not necessary to adjust the reference position after the deformation as in the prior art, and the upper limit of each area Since the reference line that determines the lower limit is fixed, there is no need to make adjustments in consideration of the area as in the past. Furthermore, the present invention aims to make it easier to distinguish the character feature portion while substantially securing the line spacing by the deformation process, and does not adjust the variation as in the prior art.

[0184] As described above, the present invention has been exemplified by using the preferred embodiment of the present invention, but the present invention should not be construed as being limited to this embodiment. It is understood that the scope of the present invention should be construed only by the claims. It is understood that those skilled in the art can implement an equivalent range based on the description of the present invention and the common general technical knowledge from the description of specific preferred embodiments of the present invention. Patents, patent applications, and literature references cited in this specification should be incorporated by reference as if the contents themselves were specifically described in the present specification. Is understood.

It is possible to secure a sufficient space between the lines of the text while maintaining the same amount of text without performing the processing of the long body. The At the same time, it is possible to enhance the speed of word comprehension 'sentence reading comprehension and prevent misreading by emphasizing character features that help character discrimination. Therefore, in addition to reading long texts on small mobile devices, reading newspapers and novels with electronic paper, checking contracts with mobile phones, and obtaining information with digital broadcasting telops, etc. A wide range of applications can be expected.
