Abstract

While ensuring a sufficient line spacing, it makes it easy to distinguish the character features and enhances the legibility of the characters. The character pattern generation device 10 uses the adjusting unit 11 to display the coordinate position of a reference line, which is an auxiliary line common to the direction in which at least one character is arranged, for representing the characteristics of the shape of the reference character pattern for each specified character size. Is adjusted in a direction perpendicular to the direction in which at least one character of the target reference character pattern is arranged, based on the reference line coordinate information indicating the character shape characteristic defined in (1). With respect to the coordinate position of the adjusted reference line, the calculation unit 12 moves or deforms the reference character pattern to be processed by calculating the coordinates for each stroke constituting the character pattern.

Description

  The present invention adjusts the coordinate position of a reference line representing the character's characteristic shape when displaying characters on the display screen, and deforms or moves the character so as to correspond to the adjusted coordinate position of the reference line. Character pattern generation device for processing, character display device (display device) such as liquid crystal display and organic EL display for generating character data as display data using this, communication device (communication device) capable of communication via communication network ), Printing devices such as printers (printing devices), mobile devices such as mobile phone devices and portable information terminal devices (PDAs), AV devices such as television devices, and electronic information devices such as personal computers, etc. Character pattern generation program for causing a computer to execute a character data generation process to be executed Shaped pattern generation program a computer readable readable recording medium recorded.

  When displaying characters on a display screen in a mobile device such as a mobile phone device or a personal digital assistant (PDA) that is currently used generally, the size of the display screen, which is a character string drawing area, is small. For example, in the case of a mobile phone device, the size of the display screen is about 4.5 cm long × 3.4 cm wide. Nevertheless, since it is necessary to display as much information as possible on one screen, the display screen of such a mobile device is compared with the initial setting value including the line spacing data of the display screen of the personal computer. Characters are displayed with some space between lines. For example, in Windows (registered trademark) memo pad, the character height and the interval between the reference lines of adjacent lines in the vertical direction, that is, in a sentence composed of a plurality of lines, from the bottom line data y-min of a certain character frame to the next. The relationship between the line pitch representing the width of the character frame of the line up to the lowest line data y-min is 4: 4, and in the mobile phone device, the relationship between the character height and the line pitch is 4: 3.

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

  FIG. 21 is a display screen diagram showing an example of character display, where (a) is a display screen diagram showing an example of a character pattern that is the original character before transformation, and (b) is a character pattern with respect to (a). A display screen diagram showing an example in which the character point and the line pitch are reduced by 30%. (C) is a display showing an example in which the character pitch of the character pattern is reduced by 25% and the line pitch is reduced by 5% with respect to (a). Screen view (d) is a display screen view showing an example in which the character height of the character pattern is reduced by 25% only in the vertical direction with respect to (a).

  As shown in FIG. 21B, the method of reducing the character points (number of dots) and the line pitch of the character pattern increases the amount of information displayed on one screen, but is difficult to read because the characters themselves are small. Remains.

  As shown in FIG. 21C, in the method of reducing the character pitch and line pitch of the character pattern, although the amount of information displayed on one screen increases, the amount of characters displayed within a certain range increases remarkably. The problem is that the screen becomes complicated and difficult to read.

  As shown in FIG. 21 (d), in the method of reducing the character height of the character pattern by 25% only in the vertical direction, since the line spacing appears to be empty, the above-described problem that the screen becomes complicated and difficult to read as described above. Seems to be resolved. However, in the reduction only in the vertical direction, that is, in the flat body process, the entire character is uniformly reduced in the vertical direction, so that there is a possibility that it may hinder the discrimination between characters having similar character shapes. Occurs. For example, in characters “h” and “n” having similar shapes, it can be said that the character characteristic portion (characteristic shape), which is a place where the difference between them is determined, 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 characters “h” and “n” having similar shapes are less pronounced. It becomes difficult to discriminate instantaneously.

  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 or reduced, and individual characters are adjusted in accordance with the reference line. A technique for adjusting the thickness of the character line width is disclosed. According to this conventional technique, it is possible to always keep the thickness of the line segment of the character constant. Therefore, according to this conventional technique, it is possible to generate a character pattern indicating a character whose quality is maintained while suppressing variations in line width within one character.

  Patent Document 2 discloses a technique for enlarging / reducing a character according to a condition such as an adjacent character so that the quality of the character is maintained, and then aligning it with a reference line (center line). This prior art enables balance adjustment with surrounding characters. Therefore, according to this prior art, it is possible to generate a character pattern that indicates a character whose quality is maintained by suppressing variations in the appearance size of the character and balancing with the surrounding characters.

  Patent Document 3 discloses a technique for correcting an optimum overshoot amount (a portion protruding from the reference line) based on reference line position information on the character design so that the quality of the character is maintained. Yes. With this conventional technique, it is possible to adjust the balance with surrounding characters while making a specific character a deformation target. Therefore, according to this prior art, it is possible to generate a character pattern that indicates a character whose quality is maintained by suppressing variations in the appearance size of the character and balancing with the surrounding characters.

Patent Document 4 discloses a technique for calculating a character height according to a drawing area and automatically correcting a character string according to the 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.
Japanese Patent Publication No. 1-303489 (Hitachi, Ltd. “Character Output Method”) Japanese Patent Publication No. 2-5095 (Hitachi, Ltd. “Character Output Method”) Japanese Patent Publication No. 7-111077 (Brother Industries, Ltd. “Character Generation Device”) Japanese Patent Publication No. 8-132777 (Max Corporation “Character Processing Device”)

  It is said that when a human eye discriminates a character, what is being watched is a silhouette of the character, such as the unevenness of the outline of the character. The reason for this is that the character silhouette tends to show a difference from other similar characters, and represents a character characteristic portion (characteristic shape). Even if the center part of a character is hidden in a circle by tens of percent from the center of gravity where the top and bottom balance of the character is equal and the center position where the left and right balance of the character are equal, It is from such an action that it can be imagined that the character is. The ratio varies depending on the characteristics of characters such as Japanese and European, but this is not mentioned here.

  Therefore, it can be said that the easier the character feature portion is to be captured, the faster the reader's character discrimination / word understanding / sentence reading speed can be prevented and misreading can be prevented. In order to grasp the character characteristic portion firmly, a sufficient margin or a sufficient space between each displayed character is required.

  Furthermore, the fact that the screen size is small and the number of characters displayed on one line is small 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 this case, if the line spacing is narrow, not only will the number of misreads such as transfer and duplicate reading increase, but there may be a problem that it is difficult to represent or distinguish the character features.

  An easy-to-read text format is one that does not interfere with the act of concentrating on the content. Therefore, it is thought that the readability of the sentence depends on how to ensure a sufficient line spacing and make it easy to distinguish the character feature.

  According to the prior art disclosed in Patent Document 1, it is possible to obtain a certain character quality by keeping the thickness of the line segment of each character constant. However, this conventional technique does not contribute to the readability of the entire sentence because there is no action and effect that makes it possible to ensure a sufficient line spacing or to easily distinguish character features.

  According to the related art disclosed in Patent Document 2, it is possible to obtain a certain character string quality by suppressing variations in the character appearance size for individual characters. However, this conventional technique does not contribute to the readability of the entire sentence because there is no action and effect that makes it possible to ensure a sufficient line spacing or to easily distinguish character features.

  According to the prior art disclosed in Patent Document 3, it is possible to adjust the balance with surrounding characters while making a specific character a deformation target for a character string. The sheaths appear to be lined up. However, this conventional technique does not contribute to the readability of the entire sentence because there is no action and effect that makes it possible to ensure a sufficient line spacing or to easily distinguish character features.

  According to the prior art disclosed in Patent Document 4, it is possible to always output a character pattern in a drawing area by calculating a character height for a character string. However, this conventional technique does not have an effect of ensuring a sufficient line spacing or easily distinguishing a character feature, and does not contribute to the readability of the entire sentence.

  The conventional techniques of Patent Documents 1 to 4 make it easy to discriminate the character features while ensuring sufficient line spacing, whether single or combined, and improve the visible readability of the text. I can't.

  The present invention solves the above-described conventional problems, and a character pattern generation device capable of further improving the legibility of characters by making it easier to distinguish character features while ensuring sufficient line spacing.

The has the above objects can be achieved. As described above, the adjustment that makes the characteristic shape appear more is an adjustment that makes the size of different portions of each character shape larger before and after the deformation process and makes it easier to distinguish the character. In other words, the adjustment that makes the feature shape appear more is that when the character size is reduced, the proportion of the feature shape in the entire character after reduction is the feature shape that occupies the whole character before reduction. The adjustment is larger than the ratio of.

Each function of each of these means is executed by a computer based on a program 43 described later.

  The auxiliary storage device 4 stores a reference character pattern 41, a font data table 42 (at least reference line coordinate information), and a program 43 including a character generation program.

  FIG. 2 is a block diagram for explaining a configuration example of the font data table 42 of FIG.

  In FIG. 2, the font data table 42 stores a character code 421, header information 422, flag information 424, and a font design 425.

  The header information 422 stores language information 426, fixed reference line information 423A, movable reference line information 423B, and reference line coordinate information 423C as reference line information 423.

  The flag information 424 stores a stroke information flag 424A, a contact information flag 424B, and a correction information flag 424C. Details of these pieces of information, flags, and font design 425 will be described later.

  With the above configuration, first, an outline of the character pattern generation processing of the present embodiment will be described first, and then the details thereof will be described.

  First, the control device 1 reads character information such as a character code and a character size from the input device 2 for a character string to be output according to the program 43 in the auxiliary storage device 4.

  Next, the character pattern of the input character code is from the character code 421 in the font data table 42, the information about the character size is from the header information 422 in the font data table 42, and the information about the typeface is in the font data table 42. The reference character pattern having a designated character size is extracted from the reference character pattern 41.

  Further, the reference line coordinate information 423C in the font data table 42 prepared for each character size is read, and according to the character generation program 43, the coordinate position of the reference line of the reference character pattern is moved by the adjusting means 11 to set the reference line. Generate. After the reference line adjusted in this way is generated, the character pattern is generated by calculating and moving or deforming each coordinate position of the stroke constituting the reference character pattern by the calculation means 12 according to the character generation program 43.

  The reference line information 423 will be described in more detail with reference to FIG.

  FIG. 3 is a diagram for explaining the reference line information 423 of FIG. 2 in which character reference lines and strokes are defined. Details of the stroke will be described later.

  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, and the first fixed reference line.

An interval C between the second fixed reference lines 423A-2 is shown. Here, the difference in shape between the character “h” and the similar character “n” is the presence or absence of a long vertical stroke, and the size of the interval A affects the degree to which the character feature shape appears. Therefore, by changing the position of the first movable reference line 423B-1 that defines the interval A, the ratio of the long vertical line stroke, which is the character feature shape, to the entire character increases, and as a result, the character feature shape.

  FIG. 24 is a diagram for explaining a reference line when the lines are not parallel to each other. Here, a case is shown in which the distance between the reference lines of each reference line is continuously narrowed from the start point to the end point. Of course, there may be a converse that the distance between the reference lines of each reference line continuously increases from the start point to the end point.

  In FIG. 24, for example, the character “hnvy” indicates a first fixed reference line 24-1, a first movable reference line 24-2, a second movable reference line 24-3, and a second fixed reference line 24-4. . In this case, since the reference line is moved / generated in steps from the start point to the end point of the character string, the character shape feature can be maintained.

  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 using the flowchart of FIG. Details of the process will be described for each step.

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

  Next, in step S <b> 4, the adjustment unit 11 generates a reference line according 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.

  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 line 423A- of the reference line coordinate information 423C. Match 2. For example, in the case of European text (alphabet), the Y coordinate values of both ascender lines and descender lines are aligned at the same height. Since the character size itself is the same, it is possible to align the Y coordinate values of the fixed reference line. The Y coordinate value may be different only in the position of the movable reference line (for example, the first movable reference line 423B-1 and the second movable reference line 423B-2).

  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.

  As shown in FIG. 6, 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 second movable reference line of the reference character pattern 41 423B-2, a second movable reference line 423B-2 ′ read from the reference line coordinate information 423C.

  Next, in step S42, among the reference lines of the reference character pattern 41 extracted in accordance with the designated character size, the movable reference line (corresponding to the movable reference line) is used for Y using the character pattern generation program 43. The coordinate value is moved to match the movable reference line of the reference line coordinate information 423C.

  For example, in the case of European text (alphabet), the X height of the reference character pattern 41 and the Y coordinate value of the baseline are aligned with 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 moved. The previous baseline and the second movable reference line 423B-2 ′ are the baseline after movement.

  Next, in step S43, the adjustment unit 11 is used to recognize the fixed reference line and the movable reference line whose coordinate value has been moved in step S42 as new reference lines.

  In this way, in step S5 in FIG. 4, the position of the stroke constituting the character pattern is moved or deformed by the calculation unit 12 according to the character pattern generation program 43 with respect to the adjusted reference line.

  With respect to the character deformation procedure executed in step S5, details of the process will be described for each step with reference to the flowchart of FIG.

  As shown in FIG. 7, first, in step S52, it is determined according to the character pattern generation program 43 whether or not it is necessary to disassemble the characters into strokes for each character. This is a determination process that is necessary to disassemble and move or transform a character pattern into strokes in subsequent processing. For simplification and speedup of processing, characters that do not need to be decomposed into strokes. Is intended to omit the decomposition process in advance. For example, in the case of European (alphabet) letters, “o”, “c”, etc., which have only one stroke, can be cited as characters that do not need to be broken down into strokes.

  Next, when the determination result in step S52 shows that the character needs to be broken down into strokes (YES), the processing after step S53 is performed, and when the characters do not need to be broken down into strokes (NO) Then, the processing after step S54 is performed.

  In step S53, the character is decomposed for each stroke in accordance with the character pattern generation program 43.

  With respect to the character disassembling procedure executed in step S53, details of the processing will be described for each step with reference to the flowchart of FIG. When processing is started, the coordinates of (x, y) are assumed to 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.

  Next, in step S532, it is determined according to the character pattern generation program 43 whether or not the stroke information flag 424A in the flag information 424 is attached to the line segment including the found end point.

  If it is determined in step S532 that the stroke information flag 424A is attached (YES), the process of step S534 is performed, and if the stroke information flag 424A is not attached (NO), the step The processing after S533 is performed.

  In step S533, the stroke information flag 424A in the flag information 424 is attached to the line segment including the found end point. Thereby, the line segment including the found end point is decomposed as a stroke and handled individually.

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

  As a result of the determination in step S534, if the current X coordinate value is equal to the maximum value (YES), the process of step S535 is performed, and if the current X coordinate value is not equal to the maximum value (NO). Then, the processing returns to step S531 and subsequent steps, and is repeated until it becomes equal to the maximum value.

  In step S535, according to the character pattern generation program 43, it is determined whether or not the current Y 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.

  If the result of determination in step S535 is that the current Y coordinate value is equal to the maximum value (YES), the processing is terminated. If the current Y coordinate value is not equal to the maximum value (NO), step S536 and subsequent steps are performed. Is performed.

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

  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. Among these, the stroke T1 is represented by the end points 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. A contact point information flag 424B in the flag information 424 is attached to the end point 2-1 in contact with the stroke T1.

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

Further, when the character pattern has 12 points, the value of the interval A is 66, the value of the interval B is 112, and the value of the interval C is 78. These values are always referred to when the reference character pattern 41 is called.

  On the other hand, FIG. 10C shows a reference character pattern 41 which is arranged in 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.

  In step S55 of FIG. 7, the contact information flag 424B in the flag information 424 is referred to.

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

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

  In step S58, according to the character pattern generation program 43, a common correction process that is applied to many characters, or an individual correction process that is applied only to a specific character, for the character to which the correction information flag 424C is added. The correction is performed by any one of the correction processes combining the common and the individual.

For example, when the process from step S52 to step S56 is performed for the character “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 processing target is limited to the bar portion and the moving direction of the coordinate value 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. Further, when the process from step S52 to step S56 is performed for the character “y”, 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 strokes constituting the characters are decomposed and then the deformation processing is performed on the coordinate points of each stroke and the strokes are synthesized later. It is also possible to select the coordinate points to be performed 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 sequentially for the strokes collectively.
Returning to the description of the processing in FIG. 4, in step S <b> 6, the deformed character is output and displayed by the output device 3.
In the following, with respect to another example of the reference line generation procedure executed in step S4 of FIG. 4, the details of the process will be described for each step using the flowchart of FIG.

  As shown in FIG. 12, first, in step S61, as in the case of step S41 of FIG. 5, the reference character pattern 41 extracted according to the designated character code is converted into the first fixed reference line of the reference line coordinate information 423C. 423A-1 and the second 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.

  Next, in step S62, among the reference lines of the reference character pattern 41 extracted in accordance with the designated character size, the coordinate position of the original movable reference line is left as it is for the movable reference line, and the reference line coordinate information 423C. A new movable reference line is generated at the coordinate position of.

  For example, in the case of the alphabet (alphabet), a new X height and baseline is generated at a position corresponding to the Y coordinate value of the reference line coordinate information 423C, that is, a position equal to the Y coordinate value of the reference line coordinate information 423C.

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

  For example, in the case of the alphabet (alphabet), the first movable reference line 423B-1 is the original X height, the first movable reference line 423B-1 ′ is the newly generated X height at the coordinate position of the reference line coordinate information 423C, The second movable reference line 423B-2 is an original baseline, and the second movable reference line 423B-2 ′ is a newly generated baseline.

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

  FIG. 16C 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 FIG. 16A, the X height ratio is 80%, and the apparent line spacing is increased by 20%.

  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 performs 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. However, the present invention is not limited to this, and the final administrator selects and adjusts the good reference line coordinate information 423C at the time of product shipment. Further, in addition to this, the user may be able to 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 the case of FIG. In the upper, middle, and lower three levels, the same character display as in FIGS. 16A, 16B, and 16C is shown, respectively. FIG. 17 shows a state in which the middle X height 90% (FIG. 16B) is selected.

  In this way, the user can freely select a plurality of X-height height candidates that suit his / her preference. Alternatively, the user may be able to input the height of the X height numerically.

  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 character string direction of the target reference character pattern By moving the character coordinate values by increasing or decreasing the same value in the direction perpendicular to each other, or by changing the character coordinate values to different values for each character coordinate value, the drawing size, character size, character spacing, It is possible to output the same document amount as before the transformation without changing the line spacing, and it is possible to sufficiently secure the apparent line spacing without performing the long / flat body processing.

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

  FIG. 18A shows a state where the present invention is not used. Since the ratio of the interval A, interval B, and interval C in FIG. 18A is always constant regardless of the character display size, for example, when the character size is reduced, the character characteristic portion (characteristic shape; “H” and “n” have a smaller interval A, and “v” and “y” have a smaller interval C), and “h” and “n”, “v” and “y”, etc. There was a problem that became difficult.

  FIG. 18B shows a state in which the present invention is used. Since the ratio of the interval A, the interval B, and the interval C in FIG. 18B is variable depending on the character display size, for example, when the character size is reduced, the interval A or C is adjusted by adjusting the ratio of the interval B. Alternatively, there is an effect that the characteristic portions of the characters in both are emphasized, and as a result, discrimination becomes easy.

  In order to specifically show the difference between the effects of FIG. 18A and FIG. 18B, a description will be given with reference to FIG. 19A and FIG. 19B. Note that the 10 pt (point) character surrounded by a dotted line is an example of a size that is normally used on the mail screen of the mobile phone device.

  FIG. 19A shows a state in which the character size is displayed every 4 pt from 6 pt to 22 pt without using the present invention. Regardless of the character display size, the ratio of the interval B is constant. FIG. 19B shows a state in which the character size is displayed every 6 pt from 6 pt to 22 pt using the present invention. Since the ratio of the interval B is changed for each character display size, “h” and “n” and “v” and “y” can be easily distinguished as compared with the case of FIG. I understand.

  The details of the reference line coordinate information 423C will be described with reference to FIG. 20 with respect to the ratio of the interval B that differs for each character display size in FIG.

  FIG. 20 is a graph showing the ratio of the interval B in FIG. 18 (b) in which the interval B in FIG. 18 (a) in the state where the present invention is not used is set to 100% and the present invention is used. It is.

  As shown in FIG. 20, when displaying a character of 10 pt as the display size, for example, the optimum value of the interval B when the present invention is used is 85% with respect to the interval B when the present invention is not used. 80 to 90% is the optimum width. The optimum value of the character display size and the interval B is proportional, and after 22pt, the same value is used when the present invention is not used and when it is used. Or the ratio of the space | interval B when not using this invention may exceed the ratio of the space | interval B when using this invention.

  In addition, by moving or transforming characters for each stroke, character features that help character recognition are emphasized, speeding up the reader's word comprehension and reading comprehension, and preventing misreading. Can improve the legibility of the text.

  Further, when the character is moved or deformed, the reference line coordinate information 423C is operated and selected by the user and set, whereby the character display according to the preference of each user can be performed.

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

  Although not specifically described in the above embodiment, the point is that the adjustment means for adjusting the reference position of the reference character pattern with respect to the target reference character pattern, and the reference position adjusted by the adjustment means. Correspondingly, it suffices to have a calculation means for changing the coordinate position of at least one of the strokes constituting the reference character pattern by a predetermined calculation and moving or transforming the stroke. It is possible to achieve the object of the present invention, which makes it possible to more easily determine the character characterizing portion while ensuring a sufficient line spacing and further improve the legibility of the character. 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 more clearly represented. 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. Each set reference position (reference position information determined for each character size) is referred to, and a reference position corresponding to the target reference character pattern is obtained from the reference position information. This means that when the target reference character pattern is deformed to the specified character size, the reference position of the reference character pattern is adjusted by the adjusting means, but the deformation to the specified character size is the same character size. It also includes a variation to. In short, the input character information is subjected to any one of display output, print output, and communication output so as to make it easier to discriminate the character characteristic portion while ensuring sufficient line spacing.

  The adjustment that makes the characteristic shape appear more is an adjustment that makes the size of different portions of each character shape larger before and after the deformation process and makes it easier to distinguish the character. In other words, the adjustment that makes the feature shape appear more is that when the character size is reduced, the proportion of the feature shape in the entire character after reduction is the feature shape that occupies the whole character before reduction. The adjustment is larger than the ratio of.

  Here, the feature configuration of the present invention will be described repeatedly. Reference line coordinates representing the character feature shape determined for each designated character size, using an auxiliary line common to the character string representing the character feature shape as a reference line. Based on the information, adjust the coordinate position of the reference line so that the feature shape appears more in the direction perpendicular to the character string of the target reference character pattern, and adjust the character pattern for each stroke according to the adjusted reference line. Move or transform by calculating coordinates. Unlike simple length / flat body processing, the character size, character spacing, and line spacing do not change while securing the apparent line spacing, and the same document amount (information amount) as before transformation is displayed, printed, or printed. Communication output is possible.

  As described above, the present invention uses the definition of the character shape based on the skeleton, and does not require the adjustment of the line width by deformation as in the prior art. In addition, since the present invention deforms each part of the character shape sandwiched between a plurality of reference lines by enlarging or contracting, there is no need to adjust the reference position after the deformation as in the prior art, and the upper limit of each area Since the reference line for determining the lower limit is fixed, there is no need for adjustment in consideration of the area as in the prior art. Another object of the present invention is to make it easier to discriminate character character portions while substantially securing line spacing by deformation processing, and does not adjust variation as in the prior art.

  As mentioned above, although this invention has been illustrated using preferable embodiment of this invention, this invention should not be limited and 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 from the description of specific preferred embodiments of the present invention based on the description of the present invention and common general technical knowledge.
