Abstract

A device for identifying, from character content, a character code not included in a character code standard usable by the device; and generating display data in an appropriate manner. When the device (10) acquires an electronic publication or other content data and identifies a character code as a code that falls outside of a usable character code standard (e.g., a code that belongs to JIS X 0213:2004 but does not belong to JIS X 0208:1997) (B1), the device acquires glyph data from an internal or an external font data storage unit, and generates user-defined character image data (B2). Alternatively, the device (10) replaces the character code of the character with the character code of an alternate character, and generates the corresponding image data. The device (10) is also provided with an adjusting function to reduce the incongruity of the user-defined character image, and an editing function for setting the attributes of a variant character or the like.

Description

[Name of invention determined by ISA based on Rule 37.2] Display data generator

The present invention relates to a display data generation device and a display data generation method for generating display data for displaying a content image including characters on a display device.

Conventionally, a display device that displays an image corresponding to content (for example, an electronic book) including characters has been used. In this type of display device, characters are drawn by interpreting the character code included in the content data.

By the way, since there are a plurality of standards related to character codes, the character codes included in the content data may include character codes that cannot be handled by the display device that displays the content data.

In such a case, conventionally, a character code that cannot be handled by a display device and a character (external character image) image corresponding to the character code (external character image) are stored in association with each other, and the character code is stored in the content data. If it is included, the external character image is displayed.

For example, Patent Document 1 discloses a technique for storing character codes and external character images in association with each other, searching for character codes that cannot be handled from an input document, and converting the searched character codes into external character images. Yes.

Japanese Patent Publication “JP 2001-318913 A (published on November 16, 2001)”

However, in the technique of the above-mentioned Patent Document 1, it is necessary to prepare image data of an external character image in advance and store it in a display device. Therefore, it is very troublesome to prepare image data of an external character image. is there.

In addition, since it is necessary to provide a display device that displays content data including a character code with a function of storing an external character code and an external character image in association with each other and a function of searching for an external character image based on the character code. There is a problem that the configuration of the display device becomes complicated.

In addition, when using external character image data prepared in advance, if the external character image data prepared in advance is enlarged or reduced according to the character size of the content data, the external character will be blurred or crushed. There is also a problem that sometimes.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a display capable of efficiently generating display data for appropriately displaying an image of content including characters on a display device. An object of the present invention is to provide a display data generation device and a display data generation method.

In order to solve the above-described problem, the display data generation device of the present invention displays data for displaying an image corresponding to the content data on the display device based on content data that is content data including characters. The content data editing unit includes a content data editing unit that generates a character code of each character included in the content data in a character code standard that can be used by the display device. A character code discriminating unit for discriminating whether the character code is a character code, and character display data corresponding to the character code determined by the character code discriminating unit as a character code not included in the character code standard For data generation device or other device connected to display data generation device for communication The character code standard for the character code based on the character data acquired by the character data acquisition unit acquired from the font data storage unit that stores character codes and character data for a plurality of characters in association with each other. Included in the character code standard out of the character codes included in the content data, and an external character image generation unit that generates external character image data that is character image data corresponding to the character code determined to be not included An external character replacement unit that replaces the character code determined to be a character code that is not compatible with the external character image data corresponding to the character code.

According to the above configuration, since it is not necessary to store the external character image data in advance in the display device or the display data generation device, the display data can be generated efficiently. In addition, display data including characters with character codes that cannot be used in the display device can be easily generated simply by specifying a character code standard that can be used in the display device that is the target of the display data. In addition, since it is not necessary to provide a function for retrieving external character image data stored in advance in the display device (client device) or a function for acquiring external character image data from the outside, the configuration of the display device can be simplified. That is, even a display device having a relatively low processing capability that does not have the above functions can appropriately display characters that are not included in the character code standard that can be used in the display device.

Specifically, the image generation unit 35 draws an external character image based on the character shape data, style information such as color and thickness, and adjustment information regarding the size and position of the external character image acquired from the drawing adjustment unit 34. . The drawing adjustment unit 34 acquires an external character image from the image generation unit 35, generates an operation screen for the user to perform external character adjustment, and causes the display unit 17 to display the operation screen. The drawing adjustment unit 34 performs external character adjustment in accordance with an instruction from the user on the operation screen, and passes adjustment information indicating the adjustment result to the image generation unit 35. The drawing adjustment unit 34 generates an adjustment image, generates an operation screen for the user to adjust the external characters, displays the operation screen on the display unit 17, adjusts the external characters according to an instruction from the user, and adjusts the adjustment. Information may be stored. Further, the image generation unit 35 may generate an image using the stored adjustment information.

The character code standard storage unit 13 stores a plurality of types of character code standards and character codes that can be used in each character code standard. In this embodiment, the character code standard storage unit 13 stores JIS (Japanese Industrial Standard) first standard (JIS X 0208: 1997) to fourth standard (JIS X 0213: 2004), ASCII (ISO 646) as character code standards. -IRV), Latin-1 (ISO-8859-1), LAtin-5 (ISO-8859-9), etc. are stored, and the user specifies and uses the character code standard of each language. .

The font data storage unit 16 stores a font of characters corresponding to each character code that can be used in the display data generation device 10. In this embodiment, the font data storage unit 16 stores font data of character codes that can be used in Unicode 2.1. In this embodiment, the font data storage unit 16 stores a plurality of types of font data such as True Type Font such as Helvetica and MS Gothic, and Open Type Font such as Faber and Kozuka font.

The substitute character table storage unit 14 is a table that stores character codes and character codes of substitute characters of characters corresponding to the character codes in association with each other.

The content data storage unit 15 includes content data input via the input unit 11, content data being edited by the content data editing unit 12 (display data), and content data after editing processing by the content data editing unit 12 ( Display data).

The output unit 18 performs an output process of the display data generated (edited) by the content data editing unit 12. For example, the output unit 18 may output display data to a display device that is detachably connected to the display data generation device 10, and may be connected to a display device that is communicably connected via a communication network. The display data may be output. The output unit 18 outputs display data to various recording media that are detachably attached to the display data generation device 10 or to a recording device that is communicably connected via a communication network. May be. As the communication network, for example, the Internet, intranet, extranet, LAN, ISDN, VAN, CATV communication network, virtual private network, telephone line network, mobile communication network, satellite communication network, etc. can be used. It is. Further, as a transmission medium constituting the network, for example, an infrared ray such as IrDA or a remote control, Bluetooth (registered trademark), 802, such as IEEE1394, USB, power line carrier, cable TV line, telephone line, ADSL line, etc. .11 Radio, HDR, mobile phone network, satellite line, terrestrial digital network, etc. can also be used. The recording medium is, for example, a tape system such as a magnetic tape or a cassette tape, a magnetic disk such as a floppy (registered trademark) disk / hard disk, or an optical disk such as a CD-ROM / MO / MD / DVD / CD-R. A disk system including an IC card (including a memory card) / optical card or a semiconductor memory system such as a mask ROM / EPROM / EEPROM / flash ROM can be used.

(1-2. Operation of the display data generation device 10)
Next, processing in the display data generation apparatus 10 will be described with reference to the flowchart of FIG.

First, the input unit 11 acquires content information including a character code (S1). The input unit 11 may acquire content information generated by another device, or the user may directly input each character included in the content information via the input unit 11.

Further, the editing screen generation unit 21 may generate an editing screen for the user to edit the content information acquired by the input unit 11 and display it on the display unit 17. FIG. 4 is an explanatory diagram illustrating an example of an editing screen (text editor display screen) generated by the editing screen generation unit 21 and displayed on the display unit 17. The edit screen generation unit 21 displays each character included in the content information on the edit screen based on the font stored in the font data storage unit 16. That is, on the editing screen, each character included in the content information is displayed based on a character code standard (Unicode 2.1 in the present embodiment) that can be used in the display data generation device 10. Therefore, the user of the display data generation device 10 can edit each character included in the content data without being aware of the character code standard that can be used in the display device. In the editing screen, style information such as font type, character size, and color can be specified. In the present embodiment, the edit data is described in the XML format, and the style information can be specified according to the XML tag definition.

Next, the input unit 11 acquires display device information (S2). Note that the order of S1 and S2 may be reversed, and S1 and S2 may be performed in parallel.

The display device information includes character code information indicating a character code standard that can be used in a display device to which display data is supplied, font information indicating a font that can be used in the display device, and the like. In addition, when a plurality of fonts can be used by switching on the display device, information indicating each usable font, information indicating a font set by default, information indicating a font that is generally used frequently, etc. May be included.

Next, the character code determination unit 22 determines whether or not the content information acquired in S1 includes a character code (character code that cannot be used on the display device) that is outside the range of the character code standard that can be used on the display device. Is determined (S3). Specifically, the character code standard storage unit 13 stores information on character codes defined by the character code standard that can be used in the display device, and the character code determination unit 22 stores each character code included in the content information. Is included in the above information.

If it is determined in S3 that no character code outside the range of the character code standard is included, that is, if all the character codes included in the content information are character codes that can be used in the display device, S16 described later. Proceed to the process. In this case, a preview image based on display data using the character code included in the content information input via the input unit 11 as it is is displayed in the process of S16 described later.

On the other hand, when it is determined in S3 that a character code outside the range of the character code standard is included, the external character image generation unit 26 extracts one character code outside the range of the character code standard from the content information (S4). .

Next, the character form data acquisition unit 31 determines whether or not the character data corresponding to the character code extracted in S4 is stored in the font data storage unit 16 (S5). If the font type is specified, the character form data is searched from the specified type of font data. If it is determined that the data is stored in the font data storage unit 16, the character form data acquisition unit 31 acquires the character form data from the font data storage unit 16 (S6).

When a plurality of types of character data corresponding to the character code extracted in S4 are stored in the font data storage unit 16, the character data selected by the character data shift unit 32 according to an instruction from the user, or preset. The character form data corresponding to the priorities set is acquired.

For example, in the case of OpenType font, it is used for conversion and vertical / horizontal conversion to “GSUB (Glyph Substitution) table” included in the storage part called OTL (OpenType Layout) table that describes the functions and characteristics of OpenType font. Information for specifying character replacement, such as switching between characters and ruby characters, is described, thereby enabling processing such as conversion of variants.

Specifically, GSUB has a table for specifying more detailed characteristics (Features), and various specifications using tags can be made here. For example, a plurality of pieces of character shape information having a common character code can be designated. For example, the tag “aalt” means all variants of the same group (variants corresponding to the same character code), and the variants of the same group can be specified by serial numbers. That is, tags and tag numbers are given to variant characters in the same group, so that variant characters can be specified.

In the GSUB table, attributes of system (system), code (code, CID), gtag (font switching information), and alt (alternative character) are described in a tag format. The system is an attribute indicating a character code system, and the code is an attribute indicating a character code. Gtag is an attribute indicating a plurality of fonts (for example, variant characters) associated with the same character code, and alt is an attribute indicating an alternative character.

FIG. 5 is an explanatory diagram showing an example of an edit screen displayed on the display unit 17 when setting these attributes. In the example of FIG. 5, the system attribute is set to “Adobe-Japan1-6”, the code attribute is set to “6930”, the gtag attribute is set to “aalt_4”, and the alt attribute is set to “邊”. Yes. As a result, in the font information, these attributes are described as <glyph code = “6930”, gtag = “aalt_4”, alt = “邊”, system = “Adobe-Japan1-6” / ”>. The fourth variant character among all the variant characters corresponding to the character code 6930 is designated, and “邊” is set as the substitute character. In addition to the method using “aalt”, the character shape designation method is “jp78 (JIS78 character shape)”, “jp83 (JIS83 character shape)”, “trad (old character shape)”, “expt (expert character shape)”. A method using the above can be used.

Next, the image generation unit 35 acquires style information (character style information) (S7). Style information refers to conditions for displaying the character on the display device (for example, size, color, presence / absence of underline, whether to display the character in bold, whether to make it bold, Is one or more of these conditions). The style information may be specified by the user via the input unit 11 on the editing screen, or may be acquired by detecting the style information of the character in the content information.

Next, the image generation unit 35 generates an external character image based on the character shape data acquired by the character shape data acquisition unit 31 in S6 and the style information acquired in S7 (S8). Then, the drawing adjustment unit 34 determines whether or not to perform drawing adjustment (S9). When drawing adjustment is performed, the generated external character image is displayed, and the drawing adjustment unit 34 acquires drawing adjustment information input from the user via the input unit 11 (S10), and returns to S8 to obtain the drawing adjustment information. An external character image that has been adjusted accordingly is generated and displayed. On the other hand, when drawing adjustment is not performed, the character code extracted in S4 in the content information is replaced with the generated external character image data (S11), and the process proceeds to S15.

FIG. 6A is an explanatory diagram showing an example of drawing adjustment, and shows an example in which the drawing adjustment of the character “A” is performed.

The window 41 includes an image 42 in which the editing target character is displayed in a standard font (standard font adopted in the display device) and the editing target character in an external character font (font stored in the font data storage unit 16). The displayed image 43 is displayed in a different color.

When there are a plurality of fonts that can be used in the display device, the standard font is changed to another font that can be used in the display device by operating the frame portion 44 (inputting drawing adjustment information to the frame portion 44). Can be switched. When the standard font is switched, the font name displayed in the frame portion 44 is switched, and the image 42 displayed in the window portion 41 is also switched to a character image corresponding to the switched font. When there are multiple fonts that can be used on the display device, external character image data that takes into account each of these fonts (external character image data for displaying an external character image with little discomfort regardless of which font is selected) is generated. The external character image data corresponding to each font may be created, or each font may be classified into a plurality of groups, and the external character image data corresponding to each group may be created. .

Also, an external character font can be switched to another font stored in the font data storage unit 16 by operating the frame unit 45 (inputting drawing adjustment information to the frame unit 45). When the external character font is switched, the font name displayed in the frame portion 45 is switched, and the image 43 displayed in the window portion 41 is also switched to a character image corresponding to the font after switching.

Also, the font size of the image 42 and the image 43 can be switched by operating the frame portion 46 indicating the font size (inputting drawing adjustment information to the frame portion 46).

Further, by operating the value of the frame portion 47 indicating the size ratio (inputting drawing adjustment information to the frame portion 47), the external character font for the drawing area (drawing area) 43a (or the standard font image 42) is displayed. The ratio of the size of the image 43 (the drawing size of the image 43 with respect to the size of the drawing area 43a) can be changed. Further, by operating the values of the frame portion 48 indicating the X-axis adjustment amount and the frame portion 49 indicating the Y-axis adjustment amount (inputting drawing adjustment information to the frame portions 48 and 49), the image of the external character font The display position (drawing position) in the X-axis direction (horizontal direction) and the Y-axis direction (vertical direction) in the 43 drawing areas 43a can be changed.

When the “OK” button is operated, the drawing adjustment unit 34 determines that no further drawing adjustment is performed, and external character image data corresponding to the image 43 of the external character font displayed at that time is displayed as content data ( (Display data). When the “Cancel” button is operated, the contents adjusted using the drawing adjustment image are canceled, and the external character image data in the state before displaying the drawing adjustment image is maintained.

In addition to the drawing adjustment image shown in FIG. 6A, an image (preview image) corresponding to display data including the character to be adjusted and its surrounding characters may be displayed on the display unit 17. FIG. 6B is an explanatory diagram illustrating an example of a preview image together with a drawing adjustment image. In the example shown in this figure, the character surrounded by a circle is a character image displayed in accordance with the external character image data adopted in the display data. The image data of the preview image may be generated by the preview image generation unit 25 or the image generation unit 35.

As shown in FIGS. 6B and 7, when the standard font of the display device and the font of the external character image data are different, even if the font size of both images is set to the same value, the size of the displayed character is It may be different. That is, even if the font size is the same, the size of the drawing area may differ depending on the font, so that when displayed side by side with other fonts, the size of the displayed character may be uncomfortable.

Also, if the font is different, the display position of the character in the drawing area may be different, and if the character with a different font is displayed side by side, the display position of the character may be shifted. As shown in FIG. 7, since the size of the drawing area may differ depending on the font, if the standard font of the display device and the font of the external character image data are different, the positions of the base lines of the external character image and the standard font are shifted. May end up. Therefore, by adjusting the external character image while confirming the preview image, it is possible to generate content data (display data) with a small shift in character size and character display position. Note that the drawing adjustment is not necessarily performed every time the external character image is generated. For example, adjustment information regarding the position adjustment amount and size ratio is stored for each type of font stored in the font data storage unit 16, and the image generation unit 35 for the font characters for which the adjustment information is stored. However, an external character image may be generated based on the adjustment information.

In S5, when the character data acquisition unit 31 determines that the font corresponding to the character code extracted in S4 is not stored in the font data storage unit 16, the alternative character conversion unit 24 stores the character in the alternative character table. It is determined whether a character code that can be used in the display device and is a character code of an alternative character corresponding to the code is stored (S12).

FIG. 8A is an explanatory diagram showing an example of a description format of the alternative character table. As shown in this figure, in the substitute character table, a character code and a character code of a substitute character of a character corresponding to the character code are recorded in association with each other. The substitute character is preferably a standard character that can be used in each character code standard that is widely used.

If it is determined in S12 that a character code of an alternative character that can be used in the display device is stored, the alternative character conversion unit 24 converts the character code extracted in S4 in the content data into the character code of the alternative character. The process proceeds to S15. Note that only one alternative character may be stored in association with each other, or a plurality of alternative characters may be stored in association with each other. In addition, when storing a plurality of substitute characters, priorities are assigned to the plurality of substitute characters, and the character codes of the substitute characters with the highest priority among the substitute characters available on the display device You may make it replace with.

On the other hand, if it is determined in S12 that the character code of the substitute character that can be used in the display device is not stored, the substitute character conversion unit 24 cannot display the character code extracted in S4 in the content data (display data). The character code of a predetermined symbol (for example, “=”) indicating a character is converted, and the process proceeds to S15.

In the present embodiment, when an external character image cannot be generated, it is replaced with a substitute character. However, as shown in FIG. 8B, when an external character can be generated, an alternative character is added to the external character image data of the character. Display image data associated with the character code may be generated. As a result, it is possible to display an external character image on the display device and to perform a keyword search using alternative characters. That is, the character code of the substitute character is not used for display on the display device, but search processing using the substitute character can be performed.

In S15, the external character image generation unit 26 uses a character code that is out of the character code standard range that cannot be used in the display device and is not replaced with external character image data or converted into an alternative character code. Is determined to remain in the content data (display data) (S15). If it is determined that the character code is left, the processing from S4 is performed on the remaining character code. On the other hand, if it is determined that it does not remain, the process proceeds to S16.

In S16, the preview image generating unit 25 generates a preview image corresponding to the display data and displays it on the display unit 17 (S16).

Thereafter, the content data editing unit 12 determines whether or not to perform further editing processing on the display data (S17). This determination may be made according to an instruction from the user input via the input unit 11, for example. Note that when the edit screen generation unit 21 generates an edit screen as shown in FIG. 4, the character displayed according to the external character image data is replaced with another character (character displayed according to the character code). In order to be able to identify easily, it displays with the display form which differs from the above-mentioned other character. For example, the color of the character may be different, the thickness may be different, and whether it is italic may be different. Or you may display a line, a symbol, etc. on the character of the character displayed according to external character image data, or the neighborhood. Thus, when the user performs a peer review, the external character image can be easily identified while comparing the editing screen and the preview screen, and the suitability of the generated external character image can be efficiently confirmed.

If it is determined that the editing process is to be performed, the content data editing unit 12 performs the editing process according to the user's instruction and returns to the process of S16.

On the other hand, when it is determined in S17 that the editing process is not performed, the content data editing unit 12 outputs the generated display data to a predetermined output destination (S19), and ends the process. Note that the output destination of the display data is not particularly limited. For example, another device (for example, a display device that displays display data, a server device that accumulates display data, or a display device) is output from the output unit 18.
