Description

  The present invention relates to an information terminal device that performs display according to a layout of original data.

  Mobile phone terminal devices having a message transmission / reception function in addition to a voice communication function have become widespread. Among such mobile phone terminal devices, there are devices that can send and receive messages to and from an information processing device such as a personal computer (PC) or a mobile phone terminal device of another business operator.

The mobile phone terminal device has a smaller number of display pixels than the information processing device such as a PC, and the number of characters that can be displayed in one line is limited. For this reason, a mobile phone terminal device that changes a line feed code to a position where it can be easily seen is known (for example, see Patent Document 1).
JP 2003-67365 A (page 5, FIG. 3)

  Line feed codes used in information processing apparatuses are widespread and include [CR + LF] (“0D” h [h: hexadecimal notation] + “0A” h), [LF] (“0A” h), [CR ] ("0D" h). Since there are three types of line feed codes in an e-mail message, if a message received from a device with a different line feed code is displayed as it is, the line layout is not performed and the display layout may change. Moreover, in the invention described in the above-mentioned Patent Document 1, there is a problem that the display layout is changed from the original data because the line feed position is intentionally changed on the terminal side.

  Further, since the mobile phone terminal device has a limited memory capacity, characters that can be implemented as fonts may be limited. For example, UTF-8 defines characters in simplified Chinese, traditional Chinese, Korean, etc. in addition to Japanese, but mobile phone terminals distributed in Japan only use Japanese characters. Implemented. The Shift-JIS also defines the third and fourth level Chinese characters, but the mobile phone terminal is often implemented only at the first and second levels.

  In such a cellular phone terminal device, if data including simplified Chinese characters is to be displayed, the simplified Chinese characters are not displayed, and this portion is clogged. In addition, even when the third level or fourth level kanji is included, this portion is clogged. For this reason, the display layout changes from the original data, and it may be difficult to guess the original data.

  In addition, for half-width characters, for example, when a German document is displayed on a mobile phone terminal device in which only English alphabets are mounted, the layout changes because some characters are not displayed.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide an information terminal device capable of performing display according to the layout of original data.

In order to solve the above-mentioned problem, an information terminal device according to claim 1 of the present invention holds typeface data of a raster image, and typeface data held in a typeface holding means for a size larger than a predetermined size.

In this information terminal device, the selection means refers to the correspondence information holding means according to the size of the character to be displayed, selects the typeface data used for the display, and the character display means selects the typeface data selected by the selection means. To display characters.

In the information terminal device according to claim 1 of the present invention, the enlargement / reduction display means enlarges / reduces the display according to the display description data according to the enlargement / reduction instruction, determines the size of the character to be displayed, and the selection means The typeface data used for the display is selected with reference to the correspondence information holding unit according to the size of the character to be displayed. If the size of the character to be displayed is a predetermined size or larger, the typeface data is held by the typeface holding unit. Of the typeface data that is the maximum size is selected, and the display position control means of the character display means determines the character size to be displayed determined by the enlargement / reduction display means and the typeface data selected by the selection means. to control the space for drawing in accordance with the font data, the maximum size of the font data size of a character to be displayed is the selection means at a predetermined size greater than that held in the font holding means If you choose to, and designated as a region for drawing in accordance with the font data selected central portion of the region to be displayed the character, character display means, and character size to be displayed and definition of vector image By displaying the characters with the typeface data selected by the selection unit according to the display description data including the definition of the display position of the character, the font data close to the original display size among the typeface data held in the typeface holding unit Display using size typeface data can be performed. Thereby, it is possible to perform display in accordance with the original display image of the display description data.

  The present invention can be applied to, for example, an information communication system that can perform communication between information terminal devices connected to a plurality of mobile communication networks.

(overall structure)
As shown in FIG. 1, for example, the information communication system according to the first embodiment of the present invention includes an HTTP (Hyper) that can provide data such as text, images, and voices with a mail server 10 and a mail server 20 that transmit and receive messages. A mobile unit comprising a Text Transfer Protocol (HTTP) server 30 and an HTTP server 40, a network 50 such as the Internet to which these servers are connected, and a mobile communication network of, for example, a W-CDMA (Wideband-Code Division Multiple Access) system A communication network 60, a mobile communication network 70 composed of a mobile communication network of PDC (Personal Digital cellular), for example, and a mobile phone terminal device (information) that can use services such as calls and communications via the mobile communication network 60 Terminal device) 80.

The mail server 10 uses, for example, SMTP (Simple Mail Transfer Protocol) to transmit a message from the mobile phone terminal device 80, and uses IMAP4 (Internet Message Access Protocol version 4) to provide a message addressed to the mobile phone terminal device 80. The mail service for the mobile phone terminal device 80 is provided.

  The mail server 20 uses, for example, SMTP (Simple Mail Transfer Protocol) to transmit a message from the mobile phone terminal device 73, and uses POP3 (Post Office Protocol version 3) to provide a message addressed to the mobile phone terminal device 73. A mail service for the mobile phone terminal device 73 is provided.

  The HTTP servers 30 and 40 provide data such as text, images, and voices to the mobile phone terminal device 80 or the mobile phone terminal device 73. Text (character string) data is provided, for example, in page description data such as HTML (Hyper Text Markup Language) format, MML (Mobile Markup Language) format, or text format. Also, image data such as wallpaper, photos, and moving images is provided in a format such as JPEG or PNG. In addition, voice data such as a ringing melody and a ringing tone is provided in a format such as SMD, MID, or MP3.

  For example, in a system including the mail server 10, the HTTP server 30, and the mobile phone terminal device 80, the line feed code of the e-mail message and text data is [CR + LF] (“0D” h [h: hexadecimal notation], “0A” h. In the system including the mail server 20, the HTTP server 40, and the mobile phone terminal device 73, the line feed code of the e-mail message and text data is [LF] (“0A” h).

  That is, the line feed code of the message handled by the mail servers 10 and 20 is, for example, [CR + LF] in the mail server 10 and [LF] in the mail server 20. The line feed code in the text data provided by the HTTP servers 30 and 40 is, for example, [CR + LF] in the HTTP server 30 and [LF] in the HTTP server 40.

  In another information processing apparatus that can be connected via the network 50 (for example, Macintosh (trademark) of Apple Inc.), the line feed code is [CR] (“0D” h).

  The mobile communication network 60 includes, for example, a digital wireless communication network employing a W-CDMA (Wideband Code Division Multiple Access) system as a wireless access system and a GPRS (General Packet Radio Service) system as a core network system, and is a short message service. SMS (Short Message Service Center) 61, MSC (Mobile Switching Circuit) 62, GGSN (Gateway GPRS Support Node) 63, SGSN (Serving GPRS Support Node) 64 constituting the core network (CN) And an RNC (Radio Network Controller) 65 and base station devices (NB: Node B) 66a, 66b,..., 66n constituting a radio access network.

  In addition, the mobile communication network 70 includes a GGSN 71 connected to the network 50, an SGSN 72 connected to the GGSN 71, and a mobile phone terminal device having a packet communication function called 2.5 generation (2.5G). Base stations (BS) 74a, 74b,... That perform wireless communication with MS (Mobile Station) 73, and base station controllers (BSC: Base Station) that control these BSs 74a, 74b,. Controller) 75, MSC 76, and GMSC (Gate MSC) 77 connected to MSC 62.

  The mobile phone terminals 80 and 73 include a mail communication function (email client) for sending and receiving e-mails in addition to a call function for making calls with other mobile phone terminals or fixed phone terminals, and an HTTP. And a browser function (browser) that uses data provided by the servers 30, 40, and the like. Note that the mobile phone terminal devices 80 and 73 can use data provided by any of the HTTP servers 30 and 40. Further, the cellular phone terminal devices 80 and 73 can use data provided by another HTTP server (not shown) connected via the network 50.

(Configuration of mobile phone terminal device 80)
Further, the mobile phone terminal device 80 includes a radio frequency (RF) unit 81 for processing a high frequency signal, an MPU 82, a memory 83, an operation key 84 for inputting an instruction from the user, and a display for the user. A display unit 85 that performs encoding / decoding of an audio signal; an MIC 87; a speaker 88; and a display control unit 89 that controls display on the display unit 85.

  The MPU 82 executes, for example, a control program stored in the memory 83, thereby controlling the communication via the mobile communication network 60, an e-mail client 200 that transmits / receives e-mail, and an HTTP server It functions as a browser 300, a display language setting unit 400, and a drawing processing unit 500 that display data provided by 30 and 40, e-mail messages, and the like. The e-mail client 200 includes a transmission / reception processing unit 210 that transmits / receives messages to / from the mail server 10 and the SMSC 61, and a transfer control unit 220 that controls message transfer.

  In the memory 83, a setting holding unit 83a that holds setting information, a data holding unit 83b that holds data such as a message, text, image, and voice, and a plurality of character code systems (for example, Shift-JIS, UTF) A character ROM 83c that holds image data of characters of (-8, ISO) is provided.

  As the image data corresponding to the Shift-JIS character code, for example, first-level and second-level characters are mounted, and third-level and fourth-level characters are not mounted. Also, as the image data corresponding to the UTF-8 character code, for example, Japanese characters are mounted, and simplified Chinese, traditional Chinese, and Korean characters are not mounted.

  By the way, when a message received from a mobile phone terminal device (for example, the mobile phone terminal device 73) or an information processing device (for example, a PC connected via the network 50) having a different line feed code from the mobile phone terminal device 80 is displayed as it is, Line breaks do not occur at the correct location, and the original message layout may be corrupted.

  In order to improve such a situation, the drawing processing unit 500 of the mobile phone terminal device 80 includes a line feed code processing unit 501 that performs line feed control according to the line feed code in the display character string data, as shown in FIG. And a character code processing unit 502 that performs character display processing according to the setting of the display language setting unit 400.

(Overview of operation)
In the mobile phone terminal device 80 configured as described above, when the e-mail client 200 requests a message from the mail server 10, for example, the execution of the process shown in FIG. 3 is started. When the e-mail client 200 requests a message from the mail server 10 and a message is transmitted from the mail server 10 in response thereto, the e-mail client 200 receives the message (S1) and holds the received message as data. Store in the part 83b (S2).

  Thereafter, the e-mail client 200 displays a menu screen including, for example, selection of display, transfer, and termination, and waits for an input from the user (S3). It is determined whether or not the input from the user is “display” (S4), and if it is “display”, display processing is executed (S5). If the input from the user is not “display”, the e-mail client 200 determines whether or not the input from the user is “transfer” (S6). The transfer process is executed (S7). If the input from the user is not “transfer”, the e-mail client 200 detects whether or not the input from the user is “end” (S8). Returning to standby (S3), if it is “end”, the process is ended.

(Display operation [line feed] details)
By the way, when a message is transmitted / received between the mobile phone terminal device 80 having a different line feed code and the mobile phone terminal device 73 or another PC, it is necessary to perform processing corresponding to the difference in the line feed code.

  A message from a PC using [CR] as a line feed code has a configuration as shown in FIG. 4, for example. In a mobile phone terminal device using [CR + LF] as a line feed code, such a line feed code [CR] in the message body is not recognized as a line feed code. For this reason, if such a message is displayed as it is, for example, as shown in FIG. 5, the line break is not generated, and the layout is different from the original message. Similarly, when displaying text data having a different line feed code, the line feed code may not be recognized as the line feed code, and the layout may be different from the original data.

  For this reason, in this mobile phone terminal device 80, the line feed code processing unit 501 of the drawing processing unit 500 performs line feed control according to the line feed code in the message (or text data).

  For example, when the e-mail client 200 instructs the drawing processing unit 500 to display a message in S5 in FIG. 3 described above, a message data string as shown in FIG. 6 is supplied to the drawing processing unit 500, for example. . FIG. 6 shows an example in which only the body part of the message shown in FIG. 4 is expressed by a Shift-JIS code. A portion surrounded by a broken line is a line feed code [CR].

  When such a data string is supplied, the line feed code processing unit 501 executes, for example, the processing shown in FIG. 7, and first detects a line feed code in the supplied data string (S11), and detects the detected line feed code. Is set as data to be line feed controlled (S12).

  Thereafter, the line feed code processing unit 501 sets the character drawing position to the initial position (for example, the upper left position of the display unit 85), and extracts data for one character from the data string (S13). Thereafter, the line feed code processing unit 501 determines whether or not the extracted data matches the data (line feed code) set in S12 described above (S14). If the extracted data for one character matches the line feed code, the line feed code processing unit 501 sets the drawing position of the next character as the beginning of the next line after the current drawing position (S15), and extracts the next character. The process proceeds to processing (S13).

  If the extracted data does not match the line feed code, the drawing processing unit 500 detects whether or not the extracted data is a character, and if it is a character, the image data corresponding to the character is sent to the character code processing unit 502. Is acquired from the character ROM 83c and written to the current drawing position in the frame buffer 89b. Further, the drawing position of the next character is set to the next drawing position of the current drawing position (the next drawing position on the same line, or the beginning of the next line if the current drawing position is the end of the line) (S17). The process proceeds to the character extraction process (S13).

  When the above processing is completed, the line feed code processing unit 501 determines whether or not the processing has been completed to the end of the data string (S18), and if not completed, moves to the next character extraction processing (S13) and ends. If so, the display process is terminated.

  When the above processing is completed, as shown in FIG. 8, for example, the message characters are displayed on the display unit 85 in a state where the line is broken at the same position as the original message. In FIG. 8, the line feed position is indicated by a downward arrow in a broken-line square. Whether or not to display a character indicating a line break can be changed by, for example, the setting of the drawing processing unit 500. If the character is not displayed, a symbol indicating a line break is not displayed.

  In the cellular phone terminal device 80, the text data attached to the message or the text data acquired by the browser 300 from the HTTP servers 30 and 40 can be stored in the data holding unit 83b. If the line feed code in such text data is different from the line feed code in the mobile phone terminal device 80, as in the case of the message, the line feed is not performed at the correct position at the time of display, and the layout of the original message is corrupted. It may end up.

  For this reason, in the cellular phone terminal device 80, line feed control similar to that in the case of the above-described message is performed when displaying text data. When displaying the text data, the data string of the text data is supplied from the e-mail client 200 or the browser 300 to the drawing processing unit 500, and display is performed by performing line feed control by the process shown in FIG. . As a result, as in the case of the message described above, it is possible to display characters in a state where a line break is made at the same position as the original data.

  As described above, since the mobile phone terminal device 80 can perform line feed processing at an accurate position regardless of the type of line feed code in an e-mail message or text data, it is faithful to the layout of the original data. Display can be made.

  In addition, since this mobile phone terminal device 80 can perform an accurate line feed process regardless of the type of line feed code, restrictions on the format of text data provided by the HTTP servers 30 and 40 can be relaxed.

(Transfer operation details)
In the mobile phone terminal device 80, a line feed code is converted when a message or text data is transferred.

  In an information terminal device that adopts [CR] or “LF” as a line feed code, if the message or text data has [CR + LF] as a line feed code, it can be displayed at the correct position even if it is displayed as it is. it can. For this reason, in the cellular phone terminal device 80, when a message is transferred or text data is transmitted, the line feed code is converted into [CR + LF] and transmitted. Specifically, for example, in S7 (transfer process) in FIG. 3 described above, for example, the process shown in FIG. 9 is executed.

  Taking the message transfer as an example, when the message transfer is instructed, the transfer control unit 220 first determines the line feed code in the message (S21). When the line feed code in the message is [CR + LF] (S22), it is not necessary to convert the line feed code, so the transfer control unit 220 sends the message to be sent based on the address, subject, etc. set separately. Is generated (S28).

  If the line feed code in the message is not [CR + LF], the transfer control unit 220 extracts data for one character from the message (S23), and whether or not the data is the line feed code determined in S21 described above. Determine (S24). If it is a line feed code, the transfer control unit 220 replaces the line feed code with [CR + LF] (S25), and then outputs one character to the output file (S26). If it is not a line feed code, the transfer control unit 220 outputs the data extracted in S23 to the output file as it is (S26).

  Thereafter, the transfer control unit 220 determines whether or not the above processing has been completed for all characters in the message (S27), and if not completed, extracts data for the next one character (S23). If processing has been completed for all characters, the line feed code that was [CR] in the data string (broken line portion) shown in FIG. 6 is converted to [CR + LF] as shown in FIG. It is in the state. Note that FIG. 10 shows only the message text.

  When the conversion of the line feed code is completed as described above, the transfer control unit 220 sends a message such as that shown in FIG. 11 based on the converted message (output file) and the address, subject, etc. of the transfer destination set separately. Is generated (S28) and transmitted to the mail server 10 (S29).

  By the above processing, even if the line feed code in the message to be transferred is not [CR + LF], it can be transferred after being converted to [CR + LF]. If the message has such a line feed code [CR + LF], even if the information terminal device corresponding to the destination address sets the line feed code to [CR] or [LF], the same position as the original message Can be used to make a line break.

  Also, when transmitting text data, by performing the same processing as in FIG. 9 described above, the text data can be transmitted with the line feed code as [CR + LF], and the information terminal corresponding to the destination address Even when the apparatus uses a line feed code of [CR] or [LF], it is possible to make a line break at the same position as the original text data.

  Therefore, in this mobile phone terminal device 80, it is possible to perform display faithful to the layout of the original data in the destination information terminal device. Further, in this mobile phone terminal device 80, when a message is transferred or text data is transmitted, the line feed code is automatically converted, so that it is possible to prevent an increase in the operation burden on the user. This effect is great in an information terminal device having a small instruction input means such as the operation key 84 such as a mobile phone terminal device, but contributes to a reduction in the operation burden on the user even when applied to an information processing device such as a personal computer. be able to.

(Modification)
In the above-described embodiments of the display operation and the transfer operation, it has been described that the [CR] or [LF] code included in the e-mail header part is also converted to the [CR + LF] code. It may be possible that some [CR + LF] codes cannot be recognized. In this case, before starting the processing flow of FIG. 7, e-mail analysis processing is performed to distinguish the header portion from the message body portion, and then only the message body portion is converted according to the processing flow of FIG. 7. You can make it.

(Display operation [character code] details)
By the way, in the mobile phone terminal device, since the memory capacity is limited, there are cases where characters that can be mounted as fonts are limited. For example, in this cellular phone terminal device 80, as described above, only the image data corresponding to the first-level and second-level characters is mounted on the character code of Shift-JIS in the character ROM 83c. Only image data corresponding to Japanese characters is implemented for the character code -8.

  In such a cellular phone terminal device 80, for example, when displaying a message including simplified Chinese characters encoded in UTF-8 as shown in FIG. 12, as shown in FIG. The characters are not displayed, and this part is clogged. For this reason, the layout of the display changes from the original message, and it may be difficult to guess the original document.

  In order to indicate characters that are not implemented, it is also possible to uniformly display specific characters that cannot be displayed. However, when the widths of characters that cannot be displayed are not constant, as in the case where full-width characters and half-width characters are mixed, the display layout changes from the original layout.

  For this reason, in this mobile phone terminal device 80, for characters that are not in the character ROM 83c (further, characters that are set not to be displayed by the setting of the display language setting unit 400), a blank corresponding to the display width of the characters is displayed. It is supposed to let you.

  In this cellular phone terminal device 80, for example, as shown in FIG. 14, a determination table 83d indicating a range of character codes that are not mounted is stored in the memory 83 for each character code system and character display width. Instead of preparing the determination table 83d, a determination function for determining whether or not the character code instructed from the line feed code processing unit 501 is mounted may be provided. In addition, in FIG. 14, only the case of full-width and half-width is shown, but when the display width is different for each character as in a specific English font, the display width is set for each character. You may make it leave.

  In the cellular phone terminal device 80, when a character code is instructed from the line feed code processing unit 501 in S17 (display processing) in FIG. 7 described above, the character code processing unit 502 performs, for example, the display processing shown in FIG. Execution is started, and it is determined by referring to the determination table 83d whether image data corresponding to the instructed character code exists in the character ROM 83c (S31).

  When the image data corresponding to the character code does not exist in the character ROM 83c, the character code processing unit 502 displays a blank character (for example, a half-width space, a full-width space, a space for the display width, etc.) corresponding to the character width in the determination table 83d. Image data is acquired and written to the current drawing position in the frame buffer 89b (S32). On the other hand, if the image data corresponding to the character code exists in the character ROM 83c, the character code processing unit 502 acquires the image data from the character ROM 83c and writes it in the current drawing position in the frame buffer 89b (S33). When the image data is thus written in the frame buffer 89b, the display processing unit 89c displays an image corresponding to the contents of the new frame buffer 89b on the display unit 85 (S34).

  When such display processing for one character is completed, the process proceeds to S13 in FIG. 7, and the line feed code processing unit 501 supplies the next character code in the data string to the character code processing unit 502. When the character code is supplied, the character code processing unit 502 repeats the processing from S31 in FIG.

  When such a process is repeated until it is determined in S18 in FIG. 7 that the data string of the text data is the last, an image is displayed for the characters mounted in the character ROM 83c, and for the characters not mounted, A space having a width corresponding to the display width of the character is displayed. Thus, for example, when the text data corresponding to FIG. 12 described above is displayed, for example, as shown in FIG. 16, a blank is displayed at the position of a character that does not have a corresponding Japanese character. By viewing such a display, the user can know that some characters cannot be displayed on the mobile phone terminal device 80.

  In such a display, characters that can be displayed on the mobile phone terminal 80 are displayed at the same position as the original text data. In such a display, since the layout of the original text data is maintained, it becomes easier for the user to guess the blank portion of characters as compared with the case of FIG.

  Further, in this cellular phone terminal device 80, since the space corresponding to the display width of the character that is not mounted is displayed in the above-described S32, the original data can be stored even when characters having different character widths are mixed. The layout is maintained. For this reason, even if there is a character that cannot be displayed, it is easy to guess the original character.

  In the above description, an example using UTF-8 has been described. However, even in the case of Shift-JIS, the same processing as in FIG. , 4th level characters).

(Modification 1)
In the above description, a blank is used as a display indicating a character that is not mounted. However, a symbol corresponding to the display width of the character (for example, a symbol having no meaning such as “−”, “_”, etc. is preferable). Even if it is made to display, the same effect as mentioned above can be obtained.

(Modification 2)
In the above description, the example using the determination table 83d indicating the range of character codes that are not mounted has been described. However, a determination table that indicates the range of character codes that are mounted may be used. In this case, if it is determined in S31 in FIG. 15 that the character code not registered in the determination table is a character that does not exist in the character ROM 83c, the operation is the same as described above.

(Modification 3)
Moreover, you may make it prepare blank data about the character code which is not mounted. In this case, the determination process in S31 and S32 in FIG. 15 described above is not necessary, and the character code processing unit 502 only acquires image data corresponding to the character code instructed from the line feed code processing unit 501 from the character ROM 83c. Good. By performing such processing, the memory utilization efficiency is reduced, but the operation speed can be increased.

(Modification 4)
By using the method of the above-described embodiment and the method of the modified example 3 together, blank data is prepared for a specific range (for example, a range of Japanese characters) even for a character without an image, and other parts. As for, a range of character codes that are not implemented may be stored in the determination table. In this case, for a character for which blank data is prepared, the process of S33 in FIG. 15 described above is executed, and a blank is displayed at the position of the character as in the case of using the determination table. For this reason, the operation speed can be increased without significantly reducing the memory utilization efficiency.

(Modification 5)
In the above description of the operation, the display control according to the character code has been described. However, when the character displayed on the display unit 85 is copied at the time of editing the text data, the mobile phone terminal device 80 Characters that cannot be displayed may be treated as white space. In this case, the character displayed as a blank is replaced with a blank character code and the copy process is executed. Thereby, it is possible to prevent a character unintended by the user from being copied.

(Modification 6)
In accordance with the user's selection, the character code used for display may be selected from the character codes installed in the character ROM 83c. In this case, for example, character codes other than the character code system used for display are registered in the above-described determination table 83d. Alternatively, the character codes of the character code system used for display are registered in the determination table, and it is determined in S31 in FIG. 15 that the character codes not registered in the determination table are characters that do not exist in the character ROM 83c. . Alternatively, the character code system used for display is registered in the setting holding unit 83a, and only the character code system used for display is determined by the character code processing unit 502 in S31. By performing such processing, for example, an operation of displaying only the language desired by the user can be realized.

(Overall configuration of SVG)
For example, as shown in FIG. 17, the information communication system according to the second embodiment of the present invention includes an SVG server 90 that provides SVG (Scalable Vector Graphics) content, SVG content, and the like in addition to the configuration shown in FIG. And a playback processing unit 600 for playing back the video. The data holding unit 83b is provided with an SVG content holding unit 83ba that holds SVG content and a Web content holding unit 83bb that holds Web content.

  For example, as illustrated in FIG. 18, the reproduction processing unit 600 displays a display image in accordance with a drawing instruction unit 611 that issues a drawing instruction to the drawing processing unit 500 in accordance with the definition in the SVG content, and a user instruction via the operation key 84. And an enlargement / reduction processing unit 612 for enlarging / reducing the image. In addition, the drawing processing unit 500 includes a character drawing unit 511 that draws characters according to an instruction from the drawing instruction unit 611 and the like, a character size selection unit 512 that selects a character size according to the definition of the determination table 83e, and a drawing instruction unit 611. And a graphic drawing unit 513 for drawing a graphic in accordance with an instruction from the above.

  The character ROM 83c stores character image data (raster images) having a plurality of points. Further, in the memory 83, for example, as shown in FIG. 19, a determination table indicating the relationship between the number of character points in the character ROM 83c corresponding to the number of character points specified in the drawing instruction from the reproduction processing unit 600 or the like. 83e is stored.

  In the SVG content, for example, as shown in FIG. 20, in addition to drawing such as a rectangle (rect), an ellipse, and a line, a character display (text) is defined. By expressing an image as such drawing information, a high-definition image can be displayed even if the image is enlarged or reduced. Such SVG content can be reproduced in-line as an image on the display screen of the Web content, but for example, as shown in FIG. 21, it can also be displayed (interactive reproduction) in an original window 85a. ing. Further, the SVG content can be enlarged / reduced according to an instruction from the user input corresponding to the button image shown in FIG.

  By the way, in an information processing apparatus such as a PC, a character image is implemented as a vector image. Therefore, by generating image data of a size (number of points) designated by such a character display instruction, a high-definition character image can be generated even if enlargement / reduction is performed.

  However, it is difficult to implement a vector font in an information processing apparatus such as a cellular phone terminal apparatus that has restrictions on the MPU and memory, and as shown in FIG. 18 described above, a plurality of rasters (one for some models) are used. Character images are implemented as images. For this reason, character image data having a size (number of points) designated in the SVG content may not be implemented. Or, when enlarging / reducing or the like is performed, there may be a situation where the image data of the character with the corresponding number of points is not mounted.

  For this reason, it is conceivable that the image data of the mounted character is enlarged / reduced and displayed. However, since the character image data is a raster image as described above, the display becomes rough when the image is enlarged / reduced. It is possible that it becomes unreadable or unreadable. Therefore, in the cellular phone terminal device 80 according to this embodiment, the character data having the optimum number of points is selected and displayed from the character image data mounted in the character ROM 83c.

(Overview of operation)
When displaying the SVG content, the drawing instruction unit 611 of the reproduction processing unit 600 gives a drawing instruction according to the definition in the SVG content in accordance with the enlargement / reduction instruction from the enlargement / reduction processing unit 612. , The graphics drawing unit 513 is instructed. The character drawing instruction is performed by, for example, instructing the character display position and the number of character points to be displayed. When receiving such an instruction, the character drawing unit 511 instructs the character size selection unit 512 to select image data of a character to be displayed, for example.

  In response to such an instruction, for example, as shown in FIG. 22, the character size selection unit 512 first checks whether or not the character image data of the designated number of points exists in the character ROM 83c (S41). If it exists, the number of points is notified to the character drawing unit 511 (S46). On the other hand, if the character image data of the designated number of points is not in the character ROM 83c, the character size selection unit 512 refers to the determination table 83e (S42), and the designated number of points is equal to a predetermined size (see FIG. It is determined whether it is smaller than 10 points in the case of 19 (S43). If not applicable, the character size selection unit 512 acquires the number of points corresponding to the instructed point number from the determination table 83e (S45), and notifies the character drawing unit 511 of the number of points (S46).

  On the other hand, when the number of points instructed from the character drawing unit 511 is smaller than a predetermined size, the character size selection unit 512 uses an alternative character (in this case, “•”, but is not limited thereto). ) Is used (S44), and the character drawing unit 511 is instructed to that effect (S46). In response to the notification from the character drawing unit 511, the character size selection unit 512 acquires character image data from the character ROM 83c (S46) and writes it to the display position instructed by the drawing instruction unit 611 in the frame buffer 89b. (S47). In addition to this processing, the graphic drawing unit 513 performs drawing of a graphic in accordance with an instruction from the drawing instruction unit 611.

  Through the above processing, an image corresponding to the SVG content is displayed according to an instruction from the drawing instruction unit 611. Furthermore, in this cellular phone terminal device 80, as described above, the image data of an appropriate number of points is displayed among the image data of the mounted characters according to the determination table 83e shown in FIG.

More specifically, for example, as shown in FIG. 23, a character with 18 points to enlarge doubling the SVG content being displayed, originally, for example, as shown in FIG. 2 4, displaying characters in 36 point There is a need to. However, as shown in FIG. 19 described above, when the maximum number of points of the image data of the mounted characters is 24 points, the character size selection unit 512 selects 24 points. As a result, in this cellular phone terminal device 80, for example, as shown in FIG. 25, 24 points of characters are displayed in the center of the space for 36 points. In this state, when the SVG content is further enlarged and displayed twice, for example, as shown in FIG. 26, 24 points of characters are displayed at the center of the 72-point space. In this way, by displaying characters with the image data of the maximum number of characters installed, the user can recognize the display position and contents of the characters. As a result, display according to the image of the SVG content can be performed to the maximum using the image data of the mounted characters.

  Further, as shown in FIG. 23 described above, when the SVG content in which characters are displayed at 18 points is reduced to a half, it is originally necessary to display the characters at 9 points. As shown in FIG. 18 described above, since the minimum number of points of the image data of the mounted characters is 12, the 9-point characters cannot be displayed as they are. In this case, for example, if image data of 12-point characters is displayed, the characters overlap as shown in FIG. For this reason, in the mobile phone terminal device 80, in the determination table shown in FIG. 19 described above, when the number of points is 10 points or less, it is defined to display with alternative characters. Thus, in this cellular phone terminal device 80, as shown in FIG. 23 described above, when the SVG content in which characters are displayed at 18 points is reduced to one half, for example, as shown in FIG. The substitute character “·” is displayed in the center of the space for the point.

  Specifically, for example, when the SVG content shown in FIG. 29 is enlarged and displayed as shown in FIG. 30, the characters in FIG. 29 are displayed as characters having the upper limit number of points like the characters in FIG. On the other hand, when the SVG content shown in FIG. 29 is reduced and displayed as shown in FIG. 31, the characters in FIG. 29 are displayed as alternative characters “·” like the characters in FIG.

(effect)
As described above, in this embodiment, the character size selection unit 512 of the drawing processing unit 500 selects the character size according to the definition of the determination table 83e, so that the original display image of the SVG content is met. Images can be displayed as images (as close as possible).

(Modification 7)
By the way, the image of the character data mounted on the actual mobile phone terminal device 80 is different for each model as shown in FIG. 32, for example. For this reason, the contents of the determination table 83e shown in FIG. 19 need to be changed according to the character image data actually mounted on the mobile phone terminal device 80. For example, in the B model, the number of points of the mounted characters is only 14 points and 16 points, so the contents of the determination table 83e are as shown in FIG. 33, for example.

  In the above description, the display of SVG content has been described as an example. However, for example, even in the display of Web content held in the Web content holding unit 83bb, by performing the same character display processing as described above, For example, when Web content is enlarged / reduced, an image can be displayed with an image along (as close as possible) the original display image of the Web content.

  In addition, a flash processing unit 620 that displays flash content is provided in the reproduction processing unit 600, and the character drawing unit 511 performs a character display process similar to the above in response to a character drawing instruction from the flash processing unit 620. Thus, for example, when the flash content is enlarged / reduced, the image can be displayed with an image that is in line with (as close as possible) the original display image of the flash content.
