Description

  The present invention relates to an information processing apparatus and an information processing program.

  Character display on a smartphone screen or a display screen is displayed using character data called a font. As fonts, there are characters with similar shapes, although they have different character types such as katakana, hiragana, kanji, and symbols. Hereinafter, the character shape is referred to as a character shape. Examples of characters with different character types and similar character shapes include, for example, katakana “ka” and kanji “power” (chikara), katakana “ro” and kanji “mouth” (kuchi), and kanji “one”. "(1) and Katakana"-"(long sound).

Characters having other characters with different character types and similar character shapes usually do not pose a problem in visibility, but may easily cause misreading, such as the following character string.
Example) 1. Difference in shooting power 2. Greece risk Concert evening 4. Type-MO00 will be delivered on April 06.

  In the case of Example 1, the kanji “power” (beginning) following the katakana character has a character shape similar to katakana “ka”, so the user may misread the word boundary and misread it. . In the case of Example 2, since the Chinese character “1” (1) following the katakana character has a character shape similar to “-” indicating a long sound, the user may misread the word boundary and misread it. is there. In the character string of Example 3, the kanji “Even” and the subsequent hiragana “be” may be mistakenly read as “tabe” in katakana. In the character string of Example 4, the letter “O” and the subsequent number “0” have similar character shapes, which may cause misreading.

  Characters that are highly likely to be mistaken for other characters with different character types and similar character shapes in the character string as in the above example, on the paper, other characters with different character types and similar character shapes It is relatively easy to distinguish between characters. However, characters that are likely to be mistaken for other characters with different character types and similar character shapes, when displayed on a liquid crystal screen, differ from other characters with different character types and similar character shapes, depending on resolution, etc. Tend to be difficult to distinguish. In addition, as in the above example, reading a sentence with a high possibility of misreading that includes other characters with different character types and similar character shapes causes confusion and strains the brain. become.

  As a technique for reducing misreading in sentences containing similar characters with different character types, characters of specific character types and specific words are collectively replaced with another display mode for all characters in the sentence data. There is technology. For example, the display mode of all katakana in the text is changed to italic and katakana is highlighted.

  However, in the conventional technology, since the display mode of characters or specific words of a specific character type in the text data is replaced at once, the display mode of the corresponding character even in a combination of characters with low possibility of misreading May be changed. This can significantly change the appearance of the original text. Even though it is desirable that the text be reproduced and displayed as faithfully as possible, the text may be in a display mode that does not conform to the author's intention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The configuration of the following embodiment is an exemplification, and the present invention is not limited to the configuration of the embodiment.

<First Embodiment>
In the first embodiment, the information processing apparatus includes a storage unit and a control unit. The storage unit stores information related to each of a plurality of characters having similar character shapes in different character types. The control unit has detected characters included in a plurality of characters that are in a character type switching portion and similar character types exist in different character types based on information included in the storage unit for the display target character string. In this case, the display mode of the detected character is changed.

Examples of character types include hiragana, katakana, kanji, alphanumeric characters, and symbols. The information regarding characters is, for example, a character code. For example, a character code defined by a standard such as JIS (Japanese Industrial Standards) may be used. The character type may be determined based on the correspondence between the character type and the character code defined by a standard such as JIS.

  Examples of characters that have similar character shapes in different character types include the Kanji “mouth” (Kuchi), the Katakana “Ro”, the symbol “□” (square), and the Kanji “Kou” (this). There are katakana “e”, kanji “ichi” (ichi) and hiragana or katakana “ー” (long sound).

  The part where the character type is switched is a part including, for example, two adjacent characters having different character types from each other in the character string to be displayed. Changing the display mode of characters includes changing the typeface, character size, and display color, adding underline, changing to italics and bold, inserting symbols that indicate delimiters before or after the character, etc. .

  Further, the storage unit may store a plurality of characters having similar character-shaped characters in different character types as a plurality of character groups corresponding to the respective character types. Each character group includes similar character-shaped characters existing in a character type different from the corresponding character type, which may lead to misreading by linking with a character of the corresponding character type. The control unit includes the first character group corresponding to the character type of the second character for the first character and the second character that are included in the part where the character type is switched and the character types are different from each other. When a character is included, the display mode of the first character may be changed.

  The character group is stored in the storage unit for each character type, for example, a hiragana character group, a katakana character group, and a kanji character group. For example, the katakana character group includes the kanji “mouth” (kuchi), the kanji “power” (chikara), the kanji “ta” (yu), and the like. These are characters that are easily misread by the katakana characters by being connected to the katakana characters, and are of a character type different from the katakana that is the target character type of the character group.

  In addition, for example, the hiragana character group may include a Chinese character “Yu” that is not similar to the character shape of any hiragana character. The Chinese character “Even” (Yu), for example, forms the word “Evening” in conjunction with Hiragana “Be”, and the Hiragana “Be” is misidentified as “Be” in Katakana. This is because the characters are highly likely to be mistaken for “ta”. In other words, the Chinese character “Even” (Yu), for the Hiragana character group, may lead to misreading by linking with the corresponding character type (Hiragana) character. What is the corresponding character type (Hiragana)? It is included in similar characters that exist in different character types (Kanji). As a result, when the word “evening” is present, the display mode of any character is changed, and misreading can be reduced.

  In addition, when the second character is the character immediately before the first character and the first character is included in the character group corresponding to the character type of the second character, You may make it change the display mode of 1 character. In addition, when the first character is not included in the character group corresponding to the character type of the second character, the control unit converts the second character into the character group corresponding to the character type of the first character. You may make it determine whether it is contained. When the second character is included in the character group corresponding to the character type of the first character, the control unit may change the second display mode.

  When the second character is the character immediately before the first character, for example, in the character string “shooting power”, the first character is the Chinese character “power” (chika), and the second character Is Katakana's “G”. Since the katakana character group includes the kanji character “power” (chika), the display mode of the kanji character “power” (chika) is changed in the character string “shooting power”.

  Further, when the second character is the character immediately preceding the first character, for example, in the character string “Evening”, the first character is “be” in hiragana, and the second character is kanji. "Evening" (Yu). Since there is no kanji that is easy to misread as hiragana “be”, it is determined that the hiragana “be” is not included in the character group for kanji. On the other hand, as described above, the Chinese character “Even” (Yu) may be included in the hiragana character group, and therefore, in the character string “Evening”, the second character “Yu” (Yu) ) Is changed.

  The control unit may be a part of the font driver. The font driver is a processing unit that performs processing for imaging a character code. Since the control unit is a part of the font driver, it is possible to change the display mode of characters in the character string to be displayed without changing the configuration of the application.

  FIG. 1 is an example of display on a portable terminal of a sentence processed by the character display control process according to the first embodiment. In the text shown in FIG. 1, characters having similar character shapes in different character types are kanji “power” (chikara), katakana “-” (long sound), and kanji “one” (one). .

  Among these characters, the character corresponding to the character in which the character type is switched and the character of the similar character shape exists in the different character type is the “kanji” of the kanji character in the “difference in shoot power” part. (From the power). Therefore, according to the character display control process according to the first embodiment, the “power” (chika) of the portion of “the difference in shoot power” is displayed differently from other characters by being underlined. It becomes an aspect. Since the display mode of characters other than the “power” (from the power) of the Chinese character in the “shooting power difference” portion is not changed, the change of the display mode can be locally suppressed.

<Device configuration>
FIG. 2 is a diagram illustrating an example of a hardware configuration of the mobile terminal 1. The portable terminal 1 is, for example, a computer such as a smartphone, a tablet terminal, a portable game machine, a music player, or a car navigation system. In FIG. 2, a hardware configuration of a smartphone is shown as an example of the mobile terminal 1. The mobile terminal 1 includes a CPU (Central Processing Unit) 101 and a storage unit 1
02, a touch panel 103, a display 104, a wireless unit 105, an audio input / output unit 106, a speaker 107, a microphone 108, and an antenna 110. The mobile terminal 1 is an example of an “information processing device”.

  The storage unit 102 includes a ROM (Read Only Memory) 102A, a RAM (Random Access Memory) 102B, and a nonvolatile memory 102C. The RAM 102B is a volatile memory such as a DRAM, for example, and provides a work area to the CPU 101. The non-volatile memory 102C is, for example, a flash memory, and stores an OS (Operating System), a font driver, a display driver, a character display control program, various programs, data used for executing the program, and the like. The character display control program is a program for performing processing for changing the display mode of a character in a character string to be displayed in a portion where the character type is switched and having a similar character type character in a different character type. The character display control program is an example of an “information processing program”. The character display control program may be a single piece of software or a part of a font driver. The RAM 102B is an example of a “storage unit”.

  The CPU 101 controls each hardware configuration by expanding a program stored in the ROM 102A or the non-volatile memory 102C in the work area of the RAM 102B and executing the expanded instructions. The CPU 101 is an example of a “control unit”.

  The touch panel 103 is one of position input devices, and is arranged on the surface of the display 104, and inputs the coordinates of the touch position of the finger corresponding to the screen of the display 104. The touch panel 103 may be any of a capacitance method, a resistance film method, a surface acoustic wave method, an infrared method, an electromagnetic induction method, and the like.

  The display 104 is, for example, a liquid crystal display (LCD). The display 104 displays screen data according to a signal input from the CPU 101.

  The wireless unit 105 is connected to the antenna 110, converts a wireless signal received through the antenna 110 into an electrical signal and outputs the electrical signal to the CPU 101, or converts an electrical signal input from the CPU 101 into a wireless signal and transmits the antenna. 110 to transmit. The wireless unit 105 is, for example, an electronic circuit corresponding to one or more of a third generation mobile communication system, a second generation mobile communication system, and LTE (Long Term Evolution).

  The audio input / output unit 106 is connected to a speaker 107 as an audio output device and a microphone 108 as an audio input device. The audio input / output unit 106 converts an audio signal input from the microphone 108 into an electric signal and outputs the electric signal to the CPU 101, or converts an electric signal input from the CPU 101 into an audio signal and outputs the audio signal to the speaker 107. To do.

  Note that the hardware configuration of the mobile terminal 1 is not limited to that shown in FIG. 2, and can be appropriately changed such as addition, replacement, and deletion. For example, the mobile terminal 1 may include an infrared communication unit, an IC card communication unit, and the like in addition to the configuration shown in FIG.

Further, the information processing apparatus is not limited to the mobile terminal 1. For example, the information processing apparatus may be a stationary computer such as a desktop PC (Personal Computer).
When the information processing apparatus is a stationary computer, the display does not have to be built in, and it is only necessary to be connected by a predetermined connection method.

  FIG. 3 is a diagram illustrating an example of a functional configuration of the mobile terminal 1. The mobile terminal 1 includes an application 11, an OS 12, a font driver 13, a display mode control unit 14, a display driver 15, a content file 16, a font file 17, a character code definition table 18, and a similar character dictionary 19 as functional configurations.

  The application 11 is a functional configuration achieved by the CPU 101 executing an application program stored in the ROM 102A or the nonvolatile memory 102C. The application 11 is an application that accompanies character display processing, such as a browser, word processing software, spreadsheet software, or drawing creation software. In the first embodiment, the application 11 is described on the assumption that it is a browser.

The application 11 reads data from the content file 16 designated by the user through the OS 12. The application 11 analyzes the typeface, character string, etc. from the read file and determines the position, size, etc. for display on the screen. The application 11 outputs a display request for the data to the OS 12. Along with the display request, the character code string, typeface, size, etc. of the data to be displayed are output to the OS 12.

  The OS 12 is a functional configuration achieved by the CPU 101 executing the OS stored in the nonvolatile memory 102C. When the display request is input from the application 11, the OS 12 calls the font driver 13. The OS 12 passes to the font driver 13 character string data including a character code string, typeface, size, and the like. Details of the information that the OS 12 passes to the font driver 13 will be described later.

  When the character string data imaged from the font driver 13 is input, the OS 12 requests the display driver 15 to display it at the designated position.

  The font driver 13 is a functional configuration achieved by the CPU 101 executing a font driver stored in the nonvolatile memory 102C. The font driver 13 generates a character string image from character string data including a character code string, a typeface, and a size.

  The font driver 13 calls the display mode control unit 14 when character string data including a character code string, a typeface, and a size is input from the OS 12. The font driver 13 outputs character string data including a character code string, a typeface, and a size to the display mode control unit 14.

  When the character string data including a character code string, a typeface, and a size after a predetermined process is input from the display mode control unit 14, the font driver 13 generates an image corresponding to the character code string from the character string data. The image is output to the OS 12.

  The display mode control unit 14 has a functional configuration achieved by the CPU 101 executing a character display control program stored in the nonvolatile memory 102C. When character string data including a character code string, a typeface, a size, and the like is input from the font driver 13, the display mode control unit 14 analyzes the character string data. The display mode control unit 14 performs a character display control process for changing the display mode of a character in a character code string where a character type is switched and having a similar character type character in a different character type. The display mode control unit 14 outputs the character string data including the character code string, the typeface, and the size processed by the character display control process to the font driver 13. Details of the processing of the display mode control unit 14 will be described later.

  The display driver 15 is a functional configuration achieved by the CPU 101 executing a display driver stored in the nonvolatile memory 102C. The display driver 15 outputs an image of the requested data to the display 104 in accordance with a display request from the OS 12.

  The content file 16 is stored in the nonvolatile memory 102C. The content file 16 stores content data used by the application 11. When the application 11 is a browser application, data acquired from the network by the browser application is stored in the content file 16.

  The font file 17 is stored in the ROM 102A. The font file 17 stores character image data corresponding to the character code. The file driver 13 converts the character code string into an image using the image data stored in the font file 17.

FIG. 4 is an example of the character code definition table 18. The character code definition table 18 is stored in the non-volatile memory 102C by installing the character display control program. The character code definition table 18 is a correspondence table between character types and start codes and end codes of character codes corresponding to the character types.

  In the example shown in FIG. 4, numbers, English letters, katakana, hiragana, and kanji are defined as character types. The character code is a 2-byte value expressed in hexadecimal. The display mode control unit 14 refers to the character code definition table 18 to determine the character type of the character in the character string, and detects the character that is the boundary of the character type. In the following description, it is assumed that the size of the character code is fixed at 2 bytes.

  FIG. 5 shows an example of a similar character dictionary 19 for katakana. The similar character shape dictionary 19 is stored in the non-volatile memory 102C by installing the character display control program. The similar character shape dictionary 19 has a character type different from the character type targeted by the similar character shape dictionary 19, and the characters included in the character type targeted by the similar character shape dictionary 19 are consecutively misread. Information about characters that are likely to be invited is stored. Characters that are likely to cause misreading due to a series of characters included in the character type targeted by the similar character dictionary 19 include, for example, characters that are similar to characters included in the target character type. The similar character shape dictionary 19 exists for each character type. FIG. 5 shows a similar character dictionary 19 for katakana. The similar character shape dictionary 19 is an example of a “character group”.

  In the example shown in FIG. 5, the similar character dictionary 19 for katakana includes the kanji “power” (chikara), the kanji “even” (Yu), the kanji “ichi” (one), and the kanji “mouth”. The character code of (Kuchi) is stored. These are all character-like characters similar to those contained in katakana. The kanji “power” is easy to misread as katakana “ka”. The Chinese character “Even” (Yu) is easily misread as Katakana “Ta”. The kanji “ichi” (ichi) is easily misread as katakana “-” (long sound). The kanji “mouth” is easily misread as katakana “ro”. In FIG. 5, characters are shown instead of character codes for convenience.

  In the similar character shape dictionary 19, a modification method is associated with each character. The modification method includes a pre-modification method in which data for modification is added before the character code of the character and a post-modification method in which data for modification is added after the character code of the character. In the case of the pre-modification method, a modification is inserted immediately before the character or the character itself is modified. In the case of the post-modification method, the display mode is such that the modification is inserted immediately after the character.

For example, the modification method includes separation, underline, italic, size change, font change, display color change, and the like. In the case of “separator”, a symbol indicating a separator is inserted immediately before or after the corresponding character. Examples of the delimiter include “/” (slash), “ ^v ” (superscript check), and the like, which is used is defined by the administrator. “Delimiter” is used for both the pre-modification method and the post-modification method.

  In the case of “underline”, the corresponding character is underlined. The type of underline may be any of a single line, a double line, a wavy line, a dotted line, etc., and which one is used is defined by the administrator. In the case of “italic”, the corresponding character is displayed with a predetermined tilt angle. In the case of “size change”, the size of the corresponding character is changed to a predetermined size. In the case of “typeface change”, the typeface of the corresponding character is changed to a predetermined typeface. “Underline”, “italic”, “size change”, and “typeface change” are used in the pre-modification method.

In the example shown in FIG. 5, for example, “underline” is designated as the pre-modification method, but even if additional information such as what kind of underline is used is defined in the similar character shape dictionary 19. Good. For example, when “size change” is designated as the pre-modification method, the size after change may be defined in the similar character shape dictionary 19. For example, a predetermined size may be set as the size definition, or a difference from the size of the original text may be set, such as 2 points larger than the size of the original text. For example, when “typeface change” is designated as the pre-modification method, the changed typeface may be defined in the similar character form dictionary 19.

  It should be noted that a modification method that causes misreading of the corresponding character is not set in the modification method of the corresponding character. For example, in the case of the Chinese character “1” (1), if “underline” is set as the modification method, the Chinese character “2” (ni) or katakana “ni” is likely to be misread. Therefore, in the example shown in FIG. 5, “separation”, which is less likely to be misread, is set in the pre-modification method of “one” (one) of kanji.

  FIG. 6 shows an example of the similar character dictionary 19 for Chinese characters. In the example shown in FIG. 6, the similar character shape dictionary 19 for kanji stores the character codes of katakana “ka”, katakana “ro”, katakana “ta”, and katakana “o” (long sound). ing. All of these characters are character-like characters similar to characters included in Kanji. Katakana's “K” is easy to misread as Kanji “Power”. Katakana's “ro” is easily misread as the kanji “mouth”. Katakana's “Ta” is easily misread as the Chinese character “Yu”. The katakana “ー” (long sound) is easily misread as the Chinese character “1” (1). In FIG. 6, characters are shown instead of character codes for convenience. The similar character shape dictionary 19 for kanji is an example of a “character group” for kanji.

  Note that the similar character shape dictionary 19 shown in FIGS. 5 and 6 includes characters having character shapes similar to the characters included in the character type targeted by the similar character shape dictionary 19. However, the similar character shape dictionary 19 includes characters included in the character type targeted by the similar character shape dictionary 19 as long as the characters included in the character type targeted by the similar character shape dictionary 19 cause misreading. It may be included even if it is not the character of the character shape similar to a character.

  For example, in the character string “Concert Evening”, the Chinese character “Yu” (Yu) may be misread as “Ta” in Katakana. This is because the Chinese character “Even” (Yu) is followed by Hiragana “be”, and Hiragana “be” is easily misread by katakana “be”. Accordingly, the Chinese character “Even” (Yu) is not a character having a character shape similar to that included in the hiragana character, but may be registered in the similar character shape dictionary 19 for hiragana characters.

  The similar character shape dictionary 19 for each character type may be periodically updated by the developer of the character display control program with, for example, misleading characters or character strings collected from the user of the mobile terminal 1. By regularly updating the similar character dictionary 19, it is possible to change the display mode of characters that may be misread more accurately.

  FIG. 7 is a diagram illustrating an example of the character type determination process of the display mode control unit 14. The character type determination process is a process for determining the character type of a character. A character string code is input in units of character string buffer from the OS 12 to the font driver 13 and from the font driver 13 to the display mode control unit 14. The character string buffer is created in a predetermined size in a predetermined area in the RAM 102B. In FIG. 7, the character codes in the character string buffer are indicated by characters for convenience.

  When called from the font driver 13, the display mode control unit 14 refers to the character code definition table 18 while shifting the character type boundary search pointer from the top of the character string buffer, and determines the character type for each character. The character type is determined by detecting a character type that includes the character code stored in the position of the character string buffer pointed to by the character type boundary search pointer.

  The display mode control unit 14 determines the character type of the character stored at the position pointed to by the character type boundary search pointer. If the character type is the same as the previous character, the display type control unit 14 sets the character type boundary search pointer as the character type. Shift to the next position in the column buffer and determine the character type of the following character. When the character type of the character stored at the position indicated by the character type boundary search pointer is a character type different from the previous character, the display mode control unit 14 performs a similar character-shaped character determination process described later. .

  In the example shown in FIG. 7, when the character type boundary search pointer indicates the storage position of “force” (character type: kanji) in the character string buffer, “ka” and the previous “g” (character type) : Katakana), the character type is different, and the similar character-shaped character determination process is started.

  FIG. 8 is a diagram illustrating an example of the similar character-shaped character determination process of the display mode control unit 14. In the similar character-shaped character determination process, when a character whose character type is different from the previous character is detected, whether or not the character is a character having a similar character shape in the character type of the previous character. This is a process of determining.

  The display mode control unit 14 compares the character stored at the position pointed to by the character type boundary search pointer with each character included in the similar character shape dictionary 19 for the character type of the character immediately before the character. It is determined whether or not the character stored in the position indicated by the type boundary search pointer is included in the similar character shape dictionary 19. When the character stored at the position pointed to by the character type boundary search pointer is included in the similar character shape dictionary 19 for the character type of the character immediately before the character, the similar character shape The display mode is changed according to the pre-modification method or the post-modification method defined in the dictionary 19. If the character stored at the position pointed to by the character type boundary search pointer is not included in the similar character shape dictionary 19 for the character type of the character immediately before the character, the character type boundary search pointer points to The position is shifted to the next position in the character string buffer, and the character type determination process is performed for the next character.

  In the example shown in FIG. 8, the “force” (chika) pointed to by the character type boundary search pointer is included in the katakana similar character dictionary 19, and therefore, a predetermined modification is applied to the “force” (chika). As shown, the display mode is changed. A more detailed description of the processing of the display mode control unit 14 will be described later with reference to FIGS. 11A to 11C.

FIG. 9 is a diagram illustrating an example of a format of input data from the OS 12 to the font driver 13. First, an example of the calling function of the font driver 13 is as follows.
Call format Function name (address of input data on RAM 102B, output image storage destination buffer address, processing result)
Call function
Xfnt_create_bitmap (& sString, & bImageBuf, & result)

  The font driver 13 is called by the call function, and data in the format shown in FIG. 9 is input. The address of the input data on the RAM 102B in the calling function is the start address of the character string buffer. In FIG. 9, the memory arrangement is also shown along with the data format. The data input to the font driver 13 stores display mode control information at the top. The display mode control information is information indicating the display mode such as the font type and size of the character string.

In the example shown in FIG. 9, the display mode control information is 1-byte “ES (Escape Seq
uence) typeface, “gothic”, “ES size”, “12”. “ES typeface” is a code indicating that the subsequent 1 byte is control information of the typeface. “Gothic” is information instructing to display a character string in a Gothic style. “ES size” is a code indicating that the subsequent 1-byte data is size control information. “12” is information instructing to display the character string in a size of 12 points. When the display mode is changed, the display mode control information is inserted immediately before the first character of the change target part.

  The input data to the font driver 13 stores a character code string to be displayed following the display mode control information. The size of the character code for one character is 2 bytes in the case of the JIS standard.

  Data input from the font driver 13 to the display mode control unit 14 is also in the same format as the data shown in FIG.

  FIG. 10 is an example of data in which the display mode of some characters is changed by the character display control process by the display mode control unit 14. In the character string of the example shown in FIG. 10, the display mode of “force” (being) is changed as described in FIG. In FIG. 10, the display mode is changed so that the “force” (from now on) is underlined.

  The display mode control unit 14 shifts the character code string after “force” (beginning) 2 bytes backward, and displays “ES modification” and “underline” as display mode control information in the empty 2 byte area. Store. Since the display mode of the characters after “no” remains as the original text, the display mode control unit 14 displays the first display immediately after “force” (from the beginning) in order to return the display mode after “no” to the original text. Display mode control information having the same content as the mode control information is inserted.

  More specifically, the display mode control unit 14 shifts the character code string after “no” 4 bytes backward, and in the vacant 4-byte area, “ES font” ”,“ Gothic ”,“ ES size ”, and“ 12 ”are stored.

  The display mode control unit 14 outputs partially changed data to the font driver 13 as in the example shown in FIG. By the processing of the display mode control unit 14, the image generated by the font driver 13 of the character whose display mode has been changed is replaced.

<Process flow>
11A, 11B, and 11C are examples of a flowchart of the character display control process of the display mode control unit 14. FIG. The process shown in FIG. 11A is started when a character code string in the character string buffer is input to the display mode control unit 14. The execution subject of the character display control process shown in FIGS. 11A to 11C is the CPU 101 that executes the character display control program, but in FIGS. 11A to 11C, the display mode control unit 14 is the execution subject for convenience. explain.

  In OP1, the display mode control unit 14 sets the character type boundary search pointer to the address of the first RAM 102B of the character string buffer. The address of the RAM 102B at the head of the character string buffer is specified by the input parameter of the call function of the font driver. In the following, when simply expressed as “address”, it indicates the address of the RAM 102B.

In OP2, the display mode control unit 14 determines whether the data stored in the reference destination address of the character type boundary search pointer is the control code of the display mode control information. If the data stored at the reference address of the character type boundary search pointer is the control code of the display mode control information (OP2: YES), the process proceeds to OP3. If the data stored in the reference destination address of the character type boundary search pointer is not the control code of the display mode control information (OP2: NO), the process proceeds to OP4.

  In OP3, the display mode control unit 14 advances the reference destination address of the character type boundary search pointer by 2 bytes. Thereafter, the process proceeds to OP2.

  In OP4, the display mode control unit 14 refers to the character code for one character stored in the reference destination address of the character type boundary search pointer. In OP5, the display mode control unit 14 refers to the character code definition table 18 and determines the character type of the character stored at the reference destination address of the character type boundary search pointer. The process of OP5 corresponds to a character type determination process.

  In OP6, the display mode control unit 14 determines whether or not the character stored at the current reference destination address is the first character in the character string buffer. If the character stored at the current reference address is the first character in the character string buffer (OP6: YES), the process proceeds to OP8. If the character stored at the current reference address is not the first character in the character string buffer (OP6: NO), the process proceeds to OP7.

  In OP7, the display mode control unit 14 determines whether or not the character type of the character stored at the current reference destination address matches the character type of the character one character before. If the character type of the character stored at the current reference address matches the character type of the character one character before (OP7: YES), the process proceeds to OP8. If the character type of the character stored in the current reference address is different from the character type of the character one character before (OP7: NO), the process proceeds to OP21 in FIG. 11B.

  In OP8, the display mode control unit 14 stores the character type of the character stored at the current reference destination address in the RAM 102B. This storage is, for example, overwrite storage.

  In OP9, the display mode control unit 14 advances the reference destination address of the character type boundary search pointer by one character. In the first embodiment, it is assumed that a JIS standard character code is used, so the size of one character is 2 bytes.

  In OP10, the display mode control unit 14 determines whether or not the processing has been completed up to the end of the character string buffer. When the process is completed up to the end of the character string buffer (OP10: YES), the process proceeds to OP11. If the process has not been completed up to the end of the character string buffer (OP10: NO), the process proceeds to OP2.

  In OP <b> 11, the display mode control unit 14 outputs the processed character code string to the font driver 13. Thereafter, the process illustrated in FIG. 11A ends.

  In OP21 of FIG. 11B, the display mode control unit 14 stores the current reference destination address of the character type boundary search pointer in the RAM 102B as the boundary position. Hereinafter, the character at the boundary position is referred to as a boundary character.

In OP22, the display mode control unit 14 refers to the entry in the similar character shape dictionary 19 for the character type of the character immediately before the boundary character. In OP23, it is determined whether or not the boundary character matches the character included in the reference entry of the similar character shape dictionary 19 for the character type of the immediately preceding character. If the boundary character matches the character of the reference entry of the similar character shape dictionary 19 for the character type of the immediately preceding character (OP23: YES), the process proceeds to OP24. If the boundary character does not match the character in the reference entry of the similar character shape dictionary 19 for the character type of the immediately preceding character (OP23: NO), the process proceeds to OP31 in FIG. 11C. The processes of OP22 and OP23 correspond to a determination process for similar character characters.

  In OP24, the display mode control unit 14 stores the character type of the character (boundary character) stored in the current reference destination address of the character type boundary search pointer in the RAM 102B.

  In OP25, the display mode control unit 14 shifts data after the current reference destination address of the character type boundary search pointer to a predetermined byte backward. The amount of shift depends on the content of the boundary character pre-modification method included in the similar character dictionary 19 for the character type being referred to. For example, when the content of the pre-modification method is “underline”, the data after the current reference address is shifted backward by 2 bytes (= control code (1 byte) + underline type (1 byte)). .

  In OP26, the display mode control unit 14 writes data according to the content of the boundary character pre-modification method included in the similar character dictionary 19 in the area vacated by the shift in the character string buffer.

  In OP27, the display mode control unit 14 shifts the pointer reference destination address by the sum of the size of the modification data written in OP27 and the size of one character.

  In OP28, the display mode control unit 14 shifts the data after the current reference destination address of the character type boundary search pointer by the size of the display mode control information at the head of the character string buffer.

  In OP29, the display mode control unit 14 writes data having the same contents as the display mode control information at the head of the character string buffer in an area vacated by the shift in the character string buffer.

  In OP30, the display mode control unit 14 shifts the current reference destination address of the character type boundary search pointer backward by the size of the display mode control information at the head of the character string buffer.

  In OP31 of FIG. 11C, the display mode control unit 14 advances the reference entry in the similar character dictionary 19 that is being referred to in OP22 of FIG. 11B. In OP 32, the display mode control unit 14 determines whether or not the reference entry of the similar character shape dictionary 19 is the last entry in the similar character shape dictionary 19. If the reference entry is the last entry in the similar character shape dictionary 19 (OP32: YES), the process proceeds to OP33. If the reference entry is not the last entry in the similar character shape dictionary 19 (OP32: NO), the process proceeds to OP22 in FIG. 11B.

  In OP33, the display mode control unit 14 refers to an address two bytes before the currently referenced address. In OP34, the display mode control unit 14 determines whether or not a control code is stored at the address referenced in OP33. If the control code is stored at the address referenced in OP33 (OP34: YES), the process proceeds to OP33. If the control code is not stored at the address referenced in OP33, that is, if the character code is stored (OP34: NO), the process proceeds to OP35.

  In OP35, the display mode control unit 14 refers to the entry in the similar character shape dictionary 19 for the character type of the boundary character. In OP36, the display mode control unit 14 determines whether or not the character immediately before the boundary character matches the character of the reference entry of the similar character shape dictionary 19 for the character type of the boundary character. The character immediately before the boundary character is a character detected by the determination in OP34.

When the character preceding the boundary character matches the character of the reference entry in the similar character shape dictionary 19 for the character type of the boundary character (OP36: YES), the display mode control unit 14 proceeds to OP37. . If the character preceding the boundary character does not match the character of the reference entry in the similar character shape dictionary 19 for the character type of the boundary character (OP36: NO), the display mode control unit 14 proceeds to OP40. .

  In OP37, the display mode control unit 14 shifts the data after the reference destination address of the current character type boundary search pointer stored in the RAM 102B in OP21 of FIG. 11B backward by a predetermined byte. How much to shift depends on the content of the post-modification method of the character immediately before the boundary character included in the similar character shape dictionary 19 for the character type being referred to. For example, when the content of the post-modification method is “separation” and a symbol indicating a delimiter is inserted, data after the current reference address is shifted backward by 2 bytes of the character code of the symbol indicating the delimiter. The

  In OP38, the display mode control unit 14 stores data in the area vacated by the shift in the character string buffer according to the content of the post-modification method of the character immediately before the boundary character included in the similar character dictionary 19 being referred to. Write.

  In OP39, the display mode control unit 14 shifts the reference destination address of the pointer by the size of the modification data written in OP38. Thereafter, the process proceeds to OP8 in FIG. 11A.

  In OP40, the display mode control unit 14 advances the reference entry in the similar character shape dictionary 19 being referred to. In OP 41, the display mode control unit 14 determines whether or not the reference entry of the similar character shape dictionary 19 being referred to is the last entry in the similar character shape dictionary 19. If the reference entry is the last entry in the similar character dictionary 19 (OP41: YES), the process proceeds to OP8 in FIG. 11A. If the reference entry is not the last entry in the similar character shape dictionary 19 (OP41: NO), the process proceeds to OP35.

<Specific example>
FIG. 12 is a diagram illustrating one specific example of the first embodiment. FIG. 12 shows a character code string at the time of input and a character code string at the time of output of the display target character string “explosive power up”. However, for convenience, not the character code but the corresponding character is shown. In addition, the memory arrangement in the character string buffer is also shown.

  Since the memory position from the 0th byte to the 3rd byte is display mode control information, the processing of OP1 in FIG. 11A and the processing of OP2 and OP3 are repeatedly executed. Since the character codes of the same character type (Kanji) continue from the 4th byte to the 8th byte in the memory location, the processing from OP4 to OP10 in FIG. 11A is repeatedly executed.

  The character type is switched from kanji to katakana in the “pa” process at the 10th byte of the memory location (FIG. 11A, OP7: NO). Therefore, “pa” is the boundary character. Thereafter, the similar character shape dictionary 19 for katakana is used as the similar character shape dictionary 19 for the character type of the boundary character “pa”. A similar character shape dictionary 19 for Kanji is used as the similar character shape dictionary 19 for the character type of the character “power” (chikara) immediately before the boundary character “pa”.

  Although the similar character shape dictionary 19 for kanji is searched for the boundary character “pa” (FIG. 11B, OP22 to OP23), there is no similar character shape of the kanji of “pa” (FIG. 11C, OP32: YES). Therefore, the similar character dictionary 19 for katakana is searched for “power” (chika), which is the character immediately before “pa” (FIG. 11C, OP33 to OP36: NO, OP40, OP41).

Since “force” (chika) has a character shape similar to katakana “ka”, “force” (chika) is registered in the similar character shape dictionary 19 for katakana (FIG. 11C, OP36: YES). Further, it is assumed that the content of the post-modification method of the entry of “power” (from the power) in the similar character dictionary 19 for katakana is “separation”. In the example shown in FIG. 12, when the modification method is “separation”, “▼” (2 bytes) is inserted as a symbol indicating the separation.

  Data after the 10th byte of the memory position is shifted backward by 2 bytes in order to insert a symbol indicating a delimiter (FIG. 11C, OP37). That is, “pa” is moved to the 12th byte of the memory location. A symbol “▼” indicating a delimiter is inserted into the 10th to 11th bytes of the memory location that is vacated by the data shift.

  Next, the character type boundary search pointer is advanced from the 10th byte to the 12th byte at the memory location (FIG. 11C, OP39), and further from the 12th byte to the 14th byte at the memory location (FIG. 11A, OP9).

  Since the 14th byte of the memory location, characters of the same character type (Katakana) as “Pa” are stored, the processing of OP4 to OP10 in FIG. 11A is repeatedly executed. As a result of the processing by the display mode control unit 14, a display mode of “explosive power ▼ power up” is obtained.

<Operational effects of the first embodiment>
According to the first embodiment, based on the similar character shape dictionary 19, when a character at a portion where the character type is switched is registered in the similar character shape dictionary 19, the display state of the character is changed, thereby changing the display mode of the character. Misreading can be suppressed while locally suppressing the change.

  Further, the similar character shape dictionary 19 is prepared for each character type. As a result, the display mode of the characters in the character type switching portion is changed in consideration of the character types of the characters before and after the character in the character type switching portion. Therefore, the preparation of the similar character shape dictionary 19 for each character type contributes to making the character whose display mode is changed more local and maintaining the appearance of the original text as much as possible.

  Further, when the boundary character immediately after the character type is switched is registered in the similar character shape dictionary 19 for the character type of the previous character, the display mode control unit 14 changes the display mode of the boundary character. . This reduces misreading by changing the display mode of characters that cause misreading by following a character of a specific character type, for example, “power” (from the power) of “shooting power” Can do.

  Further, the display mode control unit 14 does not register the boundary character immediately after the character type is switched in the similar character shape dictionary 19 for the character type of the previous character, and the similar character shape for the character type of the boundary character. When the previous character of the boundary character is registered in the dictionary 19, the display mode of the previous character is changed. As a result, for example, by changing the display mode of a character that causes misreading when a character of a specific character type follows, such as “power” of “explosion power up” (from the power), misreading is performed. Can be reduced.

  Further, by realizing the character display control program as a part of the font driver, it is possible to reduce misreading without changing the configuration of each application.
