Description

  The present invention relates to an electronic book system, an electronic book display method, and an electronic book display program for displaying an electronic book purchased via the Internet so that the electronic book can be viewed on an electronic book display device, for example.

  Conventionally, books such as novels have been mainly sold as paper media, but recently, electronic books obtained by digitizing these books have become widespread. This electronic book is sold to users mainly through the Internet, and can be browsed using an electronic book display device such as a personal computer (hereinafter referred to as “PC”), a mobile phone, and a multi-function information terminal. .

  By the way, the electronic book includes an image data format in which a book as a document is directly converted into image data, and a text data format in which characters of the book as a document are converted into character information such as a character code.

  Among them, the text data format electronic books that are mainly sold for portable electronic book display devices such as multifunction information terminals include so-called viewers that can be viewed on the electronic book display device. , Some are sold as e-book apps.

  This viewer stores character codes and typeface data corresponding to many typeface characters so as to be compatible with various books. In particular, Japanese has not only kana characters but also many kanji characters and special characters that are used in place names and personal names that are infrequently used. If these characters are included, the number of characters reaches tens of thousands.

  Thus, an electronic book having a viewer tends to have a very large data size regarding characters, and the file size of the electronic book tends to be very large.

In particular, for users who frequently purchase electronic books, electronic books having such a viewer have problems such as time-consuming downloads and the limited storage capacity of electronic book display devices.
In addition, since the characters corresponding to the character information of the electronic book are acquired from tens of thousands of characters, there is also a problem that it takes time to perform the display processing.

Therefore, a technique for selling special characters with low usage frequency through a network has been proposed (see Patent Document 1).
However, the technique disclosed in Patent Document 1 has a problem that it is necessary for a user to search for special characters and purchase separately every time an electronic book is purchased.

JP 2002-215960 A

  In view of the above problems, the present invention provides an electronic book system, an electronic book display method, and an electronic book display program capable of suppressing the file size of an electronic book and efficiently displaying an electronic book containing special characters. The purpose is to do.

  The present invention provides the electronic book created by using an electronic book creation device that creates an electronic book based on a book manuscript through a providing medium, and stores the electronic book, and various information An electronic book system that enables browsing of the electronic book using an electronic book display device that includes a display unit that displays and a browsing control unit that converts the electronic book and displays the converted electronic book on the display unit, The browsing control means stores a basic character table in which predetermined basic characters frequently used and basic character information for identifying the predetermined basic characters are registered and associated with at least one typeface data corresponding to the predetermined basic characters. The electronic book is registered with a special character that is a character that is not the predetermined basic character of the document extracted based on the basic character table, and special character information that identifies the special character. In addition, based on the special character table created by associating the typeface data corresponding to the special character, the basic character table, and the special character table, the basic character information corresponding to the character group of the document or the special character table The book character information of the content data can be browsed on the basis of the basic character table and the special character table. A character group conversion process for converting into a character group is provided.

  The providing medium may be a server connected via a communication network such as the Internet, or a storage medium such as a CD-ROM, a DVD-ROM, or a USB memory attached to an electronic book display device.

The browsing control means may be an electronic book dedicated viewer or the like, which can be provided via a providing medium.
The predetermined basic character may be a kana character, a kanji character, a symbol, or a number that is frequently used in a sentence.

The special character can be a special character that is rarely used in a plurality of electronic books. For example, kana characters, kanji characters, symbols, or external characters used for personal names or place names can be used.
The basic character information and the special character information can be character codes for identifying characters.

  According to the present invention, it is possible to provide an electronic book system capable of suppressing the file size of an electronic book and efficiently displaying an electronic book including special characters.

  Specifically, since the basic character table is obtained by selecting and registering frequently used characters from tens of thousands of characters in advance, it can be used in a plurality of electronic books. Furthermore, the data size can be significantly reduced compared with the case where character information of tens of thousands of characters is registered.

  In addition, the browsing control means can be used in a plurality of electronic books as long as they are electronic books created in the same format. That is, once the user acquires the browsing control means, only the electronic book needs to be acquired thereafter. In addition, it is possible to prevent the browsing control means from squeezing the limited storage capacity of the electronic book display device without being duplicated in the electronic book display device.

  That is, since the browsing control means provided with the basic character table is composed of components that do not depend on the contents of the electronic book or the like, it can be used in a plurality of electronic books.

  On the other hand, the special character table is created by registering and creating a character that is not a predetermined basic character from the book manuscript, so it can be used for other than the electronic book created based on the manuscript of the book from which the character is extracted. Can not. Furthermore, since the number of characters registered in the basic character table is overwhelmingly small in the special character table in which characters with low usage frequency are registered, the data size can be greatly reduced.

  In addition, since the document character information of the content data is created based on the book manuscript, it may be book-specific information that cannot be used except for an electronic book created based on the book manuscript. it can.

  That is, an electronic book provided with a special character table and content data can have a configuration unique to the book. Furthermore, by suppressing the data size of the special character table, the file size of the electronic book having the special character table and the content data can be suppressed.

  In such an electronic book and browsing control means, the electronic book is displayed on the display unit of the electronic book display device by the browsing control means so as to be browseable. That is, it is possible to configure one book that can be browsed by the electronic book and the browsing control means. The basic character table and the special character table can be used as one character table necessary for allowing the electronic book to be browsed as one book.

  Therefore, the total file size of the browsing control means and the electronic book can greatly reduce the file size by reducing the number of registered characters compared to registering tens of thousands of character information. it can.

  In addition, even if multiple typeface data corresponding to registered characters are associated with the basic character table and special character table, the total number of characters registered in the basic character table and special character table is reduced, so the total File size can be reduced. By limiting the total file size of the browsing control means and the electronic book, the limited storage capacity of the electronic book display device can be used effectively.

  Moreover, since the browsing control means that can be used in a plurality of electronic books can be used in a plurality of electronic books, it can be prepared separately from the electronic books that are unique to each book. That is, the electronic book unique to each book and the browsing control means that can be used in a plurality of electronic books can be provided separately. For example, the browsing control means can be sold attached to the multifunction information terminal, and the electronic book can be sold via the Internet or the like.

  In addition, since special characters included in the document of the book are registered in the special character table, when displaying the electronic book on the display unit of the electronic book display device so that the electronic book can be browsed, the browsing control means provides the user with the special character. It is possible to display without requiring a special operation.

  Furthermore, when the document control information of the electronic book is converted into a viewable character by the browsing control means, the total number of characters registered in the basic character table and the special character table is suppressed, so that the browsing control means is converted into the document character information. The processing time for acquiring the corresponding basic character or special character can be shortened. That is, the browsing control means can efficiently display the electronic book on the display unit of the electronic book display device.

  Therefore, the browsing control means efficiently converts the document character information of the electronic book on the basis of the basic character table and the special character table, that is, a character group that can be browsed, that is, a single character as a sentence. It can be displayed on the display unit of the display device.

  Therefore, since the electronic book provided with the special character table can be browsed using the browsing control means provided with the basic character table, the file size of the electronic book can be suppressed and the electronic book including the special character is included. Can be displayed efficiently.

  As an aspect of the present invention, the electronic book creation device includes a creation device storage unit that stores various types of information, and a creation device control unit that controls each unit, and the creation device storage unit includes the original of the book, Storing the basic character table associated with the typeface data, and referring to the basic character table in the creating device control unit to determine whether the character of the document of the book is the predetermined basic character; If it is not a predetermined basic character, the special character table registered together with the special character information as the special character is created, and a special character table creating process in which the typeface data corresponding to the special character is associated, and the basic character table And book character information obtained by converting the character group of the document into the corresponding basic character information or the special character information based on the special character table And book conversion processing that can be provided with the content data provided with the book text information, and said combining and special characters table eBook output process of outputting the created device storage unit as an electronic book.

  According to this aspect, the electronic book creation device can create an electronic book with a reduced file size.

  Specifically, most of the text (characters) of the book manuscript is registered in the basic character table, but there are also characters that are not registered in the basic character table. Characters that are not registered in the basic character table can be compensated by registering the characters that are not registered in the basic character table as special characters in the special character table by special character table creation processing.

  That is, by the special character table creation process, the text (character) of the book manuscript is registered in the basic character table or the special character table without any single character.

  Then, through the book conversion process, the text of the book manuscript is the basic character information corresponding to the characters registered in the basic character table without any single character, or the special characters corresponding to the characters registered in the special character table. It is converted into information, and book character information specific to the manuscript of the book can be created.

Furthermore, an electronic book with a reduced file size can be created by the electronic book output process.
Therefore, a special character table creation process, a book conversion process, and an electronic book output process can convert the text of a book manuscript into book character information without a single character and create an electronic book with a reduced file size. can do.

  Further, as an aspect of the present invention, the character group conversion processing of the browsing control means reads the book character information of the content data, refers to the basic character table, and corresponds to the basic character corresponding to the book character information. The presence or absence of information is determined, and if there is no basic character information corresponding to the book character information, the special character table can be referred to.

  According to this aspect, the browsing control means is required when converting the book character information into a viewable character by preferentially referring to the basic character table in which characters frequently used in the book manuscript are registered. Processing time can be shortened. That is, the book document information can be efficiently converted into a viewable character.

  Therefore, when the browsing control means first refers to the basic character table, the time required for processing the book document information can be shortened, and an electronic book including special characters can be displayed efficiently.

  As an aspect of the present invention, the basic character table may be configured to register the predetermined basic characters and the basic character information in the order of the predetermined basic characters used frequently.

  According to this aspect, in the special character table creation process and the book conversion process of the electronic book creation apparatus, the characters of the book manuscript are registered in the basic character table as compared with the case where the characters are registered in the basic character table randomly or in the order of 50 notes. The time required for determining whether or not the character is frequently used can be shortened as the character is frequently used.

  Similarly, in the character group conversion processing of the electronic book display device, the time required for determining whether or not the book character information of the electronic book is registered in the basic character table is shortened for frequently used characters. be able to.

  Accordingly, by registering predetermined basic characters and basic character information in the basic character table in order of frequency of use, special character table creation processing and book conversion processing in the electronic book creation device, and character groups in the electronic book display device The time required for the conversion process can be shortened, and an electronic book including special characters can be processed efficiently.

As an aspect of the present invention, the basic character information and the special character information can be arbitrary information for identifying the predetermined basic character and the special character.
Arbitrary information can be a uniquely defined number, code, or the like, rather than a prescribed character code such as the JIS standard.

  According to this aspect, the browsing control unit can shorten the time for converting the book character information of the electronic book into a group of characters that can be browsed, and can efficiently display the electronic book including special characters.

  For example, the numbers are set so that the basic character information and the special character information are sequentially numbered according to the usage frequency. If it does so, the book character information of an electronic book will be created by the number determined so that it may become a serial number in order according to use frequency instead of a regulation character code by book conversion processing of an electronic book creation device.

  Then, the browsing control means can determine whether to refer to the basic character table or the special character table by determining whether the number of the book character information is the number of the basic character table or the number of the special character table. .

  Therefore, the browsing control means can shorten the time required for processing as compared with the case where the basic character table and the special character table are sequentially searched to acquire characters corresponding to the book character information.

  Alternatively, the browsing control means refers to a specific range of the basic character table or the special character table including the number of the book character information according to the number of the book character information, and acquires the corresponding character for processing. Time can be shortened.

  In addition, since the book character information of the electronic book is composed of arbitrarily set basic character information and special character information, it is simply encrypted, making it difficult to view other than the browsing control means, and unauthorized use of the electronic book Can be prevented.

  Therefore, by making the basic character information and the special character information arbitrary information, it is possible to shorten the time for the browsing control means to convert the book character information into a group of characters that can be browsed. It can be displayed efficiently.

  In addition, the present invention provides the electronic book created using an electronic book creation device that creates an electronic book based on a manuscript of the book via a providing medium, and a storage unit that stores the electronic book; An electronic book display method that enables browsing of an electronic book using an electronic book display device that includes a display unit that displays various types of information and a browsing control unit that converts the electronic book and displays the converted information on the display unit. A basic character table in which predetermined basic characters frequently used and basic character information for identifying the predetermined basic characters are registered, and at least one typeface data corresponding to the predetermined basic characters is associated with the basic character table; A special character that is not the predetermined basic character of the document extracted based on the basic character table and special character information for identifying the special character is registered in the browsing control means. The basic character information or the special character information corresponding to the character group of the document based on the special character table created by associating the typeface data corresponding to the special character, the basic character table, and the special character table. In the character group conversion processing of the browsing control means, the electronic book composed of the content data including the book character information converted and created based on the basic character table and the special character table in the content data The book character information is converted into a viewable character group.

  According to the present invention, it is possible to provide an electronic book display method capable of suppressing the file size of an electronic book and efficiently displaying an electronic book including special characters.

  Specifically, the file size of the electronic book can be suppressed by using a method of configuring a book document with characters registered in the basic character table and characters registered in the special character table.

  In addition, when converting document character information of an electronic book into a viewable character group by character group conversion processing, a basic character table with a reduced number of registered characters and characters that are not in the basic character table but are in the book manuscript are displayed. By using the method of referring to the registered special character table, it is possible to shorten the time required for processing by the browsing control means.

  In addition, the present invention provides the electronic book created using an electronic book creation device that creates an electronic book based on a manuscript of the book via a providing medium, and a storage unit that stores the electronic book; An electronic book display program that enables browsing of the electronic book using an electronic book display device that includes a display unit that displays various types of information and a browsing control unit that converts the electronic book and displays it on the display unit.

Each operation to enable browsing will be described.

First, the operation of creating the electronic book 60 based on the document data 40 in the book creation apparatus 10 will be described with reference to FIG.
FIG. 6 shows a flowchart of the operation of the book creation process.

  As illustrated in FIG. 6, when the operator operates the input unit 13 to instruct the creation device control unit 16 to read the document data 40, the creation device control unit 16 starts a book creation process, and the creation device storage unit 14. The original data 40 stored in is read (step S101). Here, the creation device control unit 16 reads the JIS code of the document data 40 character by character.

  The creation device control unit 16 refers to the basic character table 52 (step S102), and determines whether or not the read JIS code is registered in the basic character table 52 (step S103).

  If the read JIS code is not registered in the basic character table 52 (step S103: No), the creation device control unit 16 uses the character corresponding to the read JIS code as a special character, along with the JIS code and the management code. Register in the table 64 (step S104).

  When a special character is registered as the first character in the special character table 64, the management code is a serial number from the basic character table 52, that is, “1001”. The code is a serial number from the first management code in the special character table 64.

  Thereafter, the creation device control unit 16 determines whether or not the JIS code for all characters of the document data 40 has been read (step S105). If the JIS code for all the characters in the document data 40 has not been read (step S105: No), the creation device control unit 16 returns the process to step S101 and performs the processing until the JIS code for all the characters in the document data 40 is read. repeat.

  In step S103, if the read JIS code is registered in the basic character table 52 (step S103: Yes), the creation apparatus control unit 16 proceeds to step S105, and performs the process for all characters of the document data 40. It is determined whether a JIS code has been read.

  When the JIS code for all characters in the document data 40 is read (step S105: Yes), the creation device control unit 16 completes the creation of the special character table 64 and temporarily stores the special character table 64 in the memory (step S106). ). Here, as shown in FIG. 5, the special character table 64 registers 100 characters from management codes “1001” to “1100” as special characters.

  When the creation of the special character table 64 is completed, the creation device control unit 16 refers to the basic character table 52 (step S107) and determines whether or not the JIS code of the document data 40 is registered in the basic character table 52. (Step S108).

  If the JIS code of the document data 40 is not registered in the basic character table 52 (step S108: No), the creation device control unit 16 refers to the special character table 64 (step S109) and adds the JIS code of the document data 40 to the JIS code. The corresponding management code is registered and created as book character information 62 (step S110).

  On the other hand, if the JIS code of the document data 40 is registered in the basic character table 52 in step S108 (step S108: Yes), the creating apparatus control unit 16 proceeds to step S110, and the JIS code of the document data 40 is obtained. The management code corresponding to is registered and created as book character information 62.

  Thereafter, the creation device control unit 16 determines whether or not the JIS codes for all characters in the document data 40 have been converted into the corresponding management codes (step S111). If the JIS code for all characters in the document data 40 has not been converted into the corresponding management code (step S111: No), the creation device control unit 16 returns the process to step S107, and returns all the characters for the document data 40. The process is repeated until the JIS code is converted into the corresponding management code.

  On the other hand, if the conversion of the JIS code for all characters of the document data 40 into the corresponding management code has been completed in step S111 (step S111: Yes), the creation device control unit 16 creates and creates the electronic book 60. The output is stored in the device storage unit 14 (step S112), and the book creation process is terminated.

  Here, when creating the electronic book 60, the creation device control unit 16 creates content data 61 in which the document character information 62 is stored. If there is an illustration or the like in the document data 40, the image data 63 is stored in the content data 61 together with the document character information 62.

  Further, the creation device control unit 16 creates an electronic book 60 from the content data 61, the special character table 64, and the font data 65 corresponding to the characters registered in the special character table 64, and outputs the electronic book 60 to the creation device storage unit 14. To do.

  In this way, the electronic book 60 created from the document data 40 is distributed and stored in the storage unit 21 of the distribution server 20 via the LAN line 2. Then, the user accesses the distribution server 20 using a WEB site or a dedicated application, and purchases the electronic book 60 to be subscribed to. Here, a user who has never purchased the viewer application 50, that is, a user who purchases the electronic book 60 for the first time purchases the viewer application 50 together.

Next, in the book display apparatus 30, the operation | movement which enables browsing with the viewer application 50 of the electronic book 60 is demonstrated using FIGS. 7-10.
7 shows a flowchart of the book display processing operation, FIG. 8 shows an application selection screen 300 for selecting the viewer application 50, and FIG. 9 shows an electronic book selection screen 310 for selecting the electronic book 60. FIG. 10 shows an electronic book display screen 320 on which the electronic book 60 is displayed.

  First, the electronic book 60 and the viewer application 50 purchased by the user from the distribution server 20 via the Internet line 3 are stored in the display device storage unit 33 in accordance with an instruction from the display device control unit 36 of the book display device 30.

  Then, the book display device 30 that stores the electronic book 60 and the viewer application 50 in the display device storage unit 33 displays an application selection screen 300 as shown in FIG. 8 on the operation display unit 32.

  The application selection screen 300 includes a viewer icon 301 that activates the viewer application 50 upon selection and pressing by the user, a notepad icon 302 that activates the notepad application, a mail icon 303 that activates the mail application, and a browser application. A browser icon 304 to be activated and a game icon 305 to activate a game application are displayed.

  When the user presses the viewer icon 301 on the application selection screen 300, the display device control unit 36 of the book display device 30 executes the viewer application 50 and displays the electronic book selection screen 310 on the operation display unit 32.

  As shown in FIG. 9, the electronic book selection screen 310 includes an application name field 311 displaying the name of the application at the top, and an electronic book stored in the display device storage unit 33 below the application name field 311. A book list 312 for displaying a list, a setting button 313 for making various settings at the bottom of the electronic book selection screen 310, and an end button 314 for ending the viewer application 50 are displayed.

  Note that the typeface of the character displayed on the operation display unit 32 is set in advance on various setting screens (not shown) displayed when the setting button 313 is pressed. In this embodiment, it is assumed that the X typeface has already been selected and set.

  When the user selects one electronic book displayed in the book list 312 on the electronic book selection screen 310 and presses the book name, an instruction from the display device control unit 36 of the book display device 30 as shown in FIG. Thus, the viewer application 50 starts the book display process and reads the selected electronic book 60 stored in the display device storage unit 33 (step S201). Here, the viewer application 50 reads the management code of the document character information 62 one character at a time.

  Then, the viewer application 50 refers to the basic character table 52 (step S202), and determines whether or not the read management code is registered in the basic character table 52 (step S203).

  If the read management code is registered in the basic character table 52 (step S203: Yes), the character corresponding to the read management code is acquired from the basic character table 52 (step S204). Thereafter, the viewer application 50 temporarily stores the acquired characters in the memory (step S207).

  On the other hand, if the read management code is not registered in the basic character table 52 in step S203 (step S203: No), the viewer application 50 refers to the special character table 64 (step S205).

  Then, the character corresponding to the read management code is acquired from the special character table 64 (step S206). Thereafter, the viewer application 50 temporarily stores the acquired characters in the memory (step S207).

  Thereafter, the viewer application 50 determines whether or not the management codes for the number of characters that can be displayed on the operation display unit 32 are read from the document character information 62 of the electronic book 60 (step S208).

  If the management code for the number of characters that can be displayed on the operation display unit 32 has not been read (step S208: No), the viewer application 50 returns the process to step S201 and starts the operation display unit from the document character information 62 of the electronic book 60. The processing is repeated until the management codes for the number of characters that can be displayed in 32 are read.

  On the other hand, if the management code for the number of characters that can be displayed on the operation display unit 32 is read in step S208 (step S208: Yes), the viewer application 50 selects the characters temporarily stored in the memory and the selection-set items. Based on the X font (X font data 53a, 65a), a font character that can be viewed on the operation display unit 32 is created (step S209).

  Then, the viewer application 50 displays the electronic book display screen 320 on which the electronic book 60 can be browsed on the operation display unit 32 (step S210), and ends the book display process.

  As shown in FIG. 10, the electronic book display screen 320 has a text column 321 in which the electronic book 60 is converted into a viewable character (sentence), and a page return for returning the page being browsed to the lower left corner of the text column 321. A button 322, a page advance button 323 that advances the page being viewed in the lower right corner of the text field 321, a setting button 313, and an end button 314 are displayed at the bottom of the electronic book display screen 320.

  When the user presses the page return button 322 or the page feed button 323 on the electronic book display screen 320, the viewer application 50 starts the book display process and updates the content displayed on the operation display unit 32.

  In this way, the electronic book 60 stored in the display device storage unit 33 of the book display device 30 is displayed on the operation display unit 32 of the book display device 30 using the viewer application 50.

  As described above, the electronic book 60 created by using the book creation device 10 that creates the electronic book 60 based on the document data 40 is sold via the distribution server 20 and the display device storage for storing the electronic book 60 is stored. The electronic book 60 can be viewed using the book display device 30 including the unit 33, the operation display unit 32 that displays various types of information, and the viewer application 50 that converts the electronic book 60 and displays it on the operation display unit 32. The basic character table 52 that registers frequently used basic characters and management codes for identifying the basic characters and associates the font data 53 corresponding to the basic characters in the viewer application 50. A special code that is a character that is not a basic character of the document data 40 extracted based on the basic character table 52, and a management code that identifies the special character And the text of the document data 40 are converted into corresponding management codes based on the special character table 64 created by associating the font data 65 corresponding to the special characters, the basic character table 52, and the special character table 64. Typeface characters that are composed of the content data 61 having the created book character information 62 and can be browsed by the viewer application 50 based on the basic character table 52 and the special character table 64. By converting to, the file size of the electronic book 60 can be suppressed, and the electronic book system 1 that can efficiently display the electronic book 60 including special characters can be provided.

  Specifically, since the basic character table 52 is a table in which frequently used characters are selected and registered from tens of thousands of characters in advance, the basic character table 52 can be used in a plurality of electronic books 60. Furthermore, the data size can be significantly reduced compared with the case where character information of tens of thousands of characters is registered.

  The viewer application 50 can be used in a plurality of electronic books 60 as long as the electronic books 60 are created in the same format. That is, once the user purchases the viewer application 50, only the electronic book 60 needs to be purchased thereafter. In addition, it is possible to prevent the viewer application 50 from pressing the limited storage capacity of the display device storage unit 33 without overlapping the book display device 30.

  That is, the viewer application 50 including the basic character table 52 is configured with components that do not depend on the contents of the electronic book 60 and the like, and thus can be used in a plurality of electronic books 60.

  On the other hand, since the special character table 64 is created by extracting and registering characters that are not basic characters from the manuscript data 40, the special character table 64 can be used except for the electronic book 60 created based on the manuscript data 40 from which characters are extracted. Can not. Furthermore, since the number of characters registered in the basic character table 52 is overwhelmingly small in the special character table 64 in which characters that are less frequently used are registered, the data size can be greatly reduced.

  Further, since the document character information 62 of the content data 61 is created based on the manuscript data 40, it is information unique to a book that cannot be used other than the electronic book 60 created based on the manuscript data 40. can do.

  That is, the electronic book 60 including the special character table 64 and the content data 61 can have a configuration unique to the book. Furthermore, by suppressing the data size of the special character table 64, the file size of the electronic book 60 including the special character table 64 and the content data 61 can be suppressed.

  In such an electronic book 60 and the viewer application 50, the electronic book 60 is displayed on the operation display unit 32 of the book display device 30 by the viewer application 50 so as to be viewable. That is, one book 70 that can be browsed by the electronic book 60 and the viewer application 50 can be configured.

  The basic character table 52 and the special character table 64 can be a single character table 71 necessary for making the electronic book 60 viewable as a single book 70.

  Therefore, the total file size of the viewer application 50 and the electronic book 60 is greatly reduced by reducing the number of registered characters, compared to the case of registering character information of tens of thousands of characters. Can do.

  Furthermore, even if the font data 53 and 65 corresponding to the registered characters are associated with the basic character table 52 and the special character table 64, the total number of characters registered in the basic character table 52 and the special character table 64 is suppressed. So you can reduce the total file size. By limiting the total file size of the viewer application 50 and the electronic book 60, the limited storage capacity of the book display device 30 can be used effectively.

  In addition, since the viewer application 50 that can be used in the plurality of electronic books 60 can be used in the plurality of electronic books 60, the viewer application 50 can be prepared separately from the electronic book 60 unique to each book. That is, the electronic book 60 unique to each book and the viewer application 50 that can be used in the plurality of electronic books 60 can be sold and purchased separately.

  In addition, since the special characters included in the document data 40 are registered in the special character table 64, when the electronic book 60 is displayed on the operation display unit 32 of the book display device 30 so as to be viewable, the viewer application 50 Can be displayed without requiring special operations for special characters.

  Further, when the viewer application 50 converts the document character information 62 of the electronic book 60 into a viewable character, the total number of characters registered in the basic character table 52 and the special character table 64 is suppressed, so that the viewer application 50 The processing time for acquiring basic characters or special characters corresponding to the document character information 62 can be reduced. That is, the viewer application 50 can efficiently display the electronic book 60 on the operation display unit 32 of the book display device 30.

  Therefore, the viewer application 50 efficiently converts the document character information 62 of the electronic book 60 based on the basic character table 52 and the special character table 64, that is, a character group that can be viewed, that is, a single character as a sentence. And can be displayed on the operation display unit 32 of the book display device 30.

  Therefore, since the electronic book 60 having the special character table 64 can be browsed using the viewer application 50 having the basic character table 52, the file size of the electronic book 60 can be suppressed, and special characters can be displayed. The included electronic book 60 can be displayed efficiently.

  The book creation device 10 includes a creation device storage unit 14 that stores various types of information and a creation device control unit 16 that controls each unit. The creation device storage unit 14 associates document data 40 and font data 53. The basic character table 52 is stored, and the creation device control unit 14 refers to the basic character table 52 to determine whether the character of the document data 40 is a basic character. By creating a special character table 64 registered together with the management code and associating the font data 65 corresponding to the special character, the character (character) of the document data 40 that is not registered in the basic character table 52 is specially selected. By registering the characters in the special character table 64 as characters, it is possible to compensate for the missing characters in the basic character table 52.

  That is, the sentence (character) of the document data 40 is registered in the basic character table 52 or the special character table 64 without any single character.

  Then, based on the basic character table 52 and the special character table 64, the book character information 62 is generated by converting the character group of the document data 40 into the corresponding management code. It is converted into a management code corresponding to the character registered in the basic character table 52 or a management code corresponding to the character registered in the special character table 64, and the book character information 62 unique to the document data 40 is created. be able to.

  Furthermore, the content data 61 including the book character information 62 and the special character table 64 are combined and output to the creation device storage unit 14 as the electronic book 60, thereby creating the electronic book 60 with a reduced file size. Can do.

  Accordingly, the book creation process can convert the characters of the document data 40 into book character information without any single character, and can create an electronic book 60 with a reduced file size.

  Further, in the book display process of the viewer application 50, the book character information 62 of the content data 61 is read, the basic character table 52 is referred to, the presence / absence of a management code corresponding to the book character information 62 is determined, and the book character information 62 If there is no management code corresponding to, the viewer application 50 preferentially refers to the basic character table 52 in which characters frequently used in the document data 40 are registered by referring to the special character table 64. Thus, the processing time required for converting the book character information 62 into a viewable character can be shortened. That is, the book document information 62 can be efficiently converted into a viewable character.

  Therefore, when the viewer application 50 first refers to the basic character table 52, the time required for processing the book document information 62 can be shortened, and the electronic book 60 including special characters can be displayed efficiently.

  In addition, by registering basic characters and management codes in the order of frequently used basic characters in the basic character table 52, the characters are randomly or 50 stored in the basic character table 52 in the book creation process of the book creation apparatus 10. Compared with the case where the characters are registered in the order of sound, the time required to determine whether or not the characters of the document data 40 are registered in the basic character table 52 can be shortened as the characters are frequently used.

  Similarly, in the book display processing of the book display device 30, the time required for determining whether or not the book character information 62 of the electronic book 60 is registered in the basic character table 52 is set as the frequently used character. Can be shortened.

  Therefore, by registering basic characters and management codes in order of frequency of use in the basic character table 52, the time required for the book creation process in the book creation apparatus 10 and the book display process in the book display apparatus 30 is shortened. The electronic book 60 including special characters can be processed efficiently.

  In addition, the electronic book 60 created using the book creation device 10 that creates the electronic book 60 based on the document data 40 is sold via the distribution server 20, and the display device storage unit 33 stores the electronic book 60. The electronic display 60 can be viewed using the book display device 30 including the operation display unit 32 that displays various information and the viewer application 50 that converts the electronic book 60 and displays it on the operation display unit 32. In the book display method, the viewer application 50 includes a basic character table 52 in which basic characters frequently used and a management code for identifying the basic characters are registered, and font data 53 corresponding to the basic characters is associated. A special character which is a character that is not a basic character of the document data 40 extracted based on the character table 52 and a management code for identifying the special character are registered, and a special character is registered. Book character information created by converting the character group of the document data 40 into a corresponding management code based on the special character table 64 created by associating the typeface data 65 corresponding to the character, the basic character table 52, and the special character table 64 The book character information 62 of the content data 61 can be viewed based on the basic character table 52 and the special character table 64 in the book display processing of the viewer application 50 for the electronic book 60 configured with the content data 61 including 62. By converting to a simple character group, the file size of the electronic book 60 can be suppressed, and an electronic book display method capable of efficiently displaying the electronic book 60 including special characters can be provided.

  Specifically, the file size of the electronic book 60 can be reduced by using the method in which the document data 40 is composed of characters registered in the basic character table 52 and characters registered in the special character table 64.

  Further, when the document character information 62 of the electronic book 60 is converted into a viewable character group by the character group conversion processing, the basic character table 52 in which the number of registered characters is suppressed, and the basic character table 52 in the document data 40 are included. By using the method of referring to the special character table 64 in which characters not included are registered, the time required for processing by the viewer application 50 can be shortened.

  Therefore, the file size of the electronic book 60 can be suppressed, and the electronic book 60 including special characters can be displayed efficiently.

  In addition, the electronic book 60 created using the book creation device 10 that creates the electronic book 60 based on the document data 40 is sold via the distribution server 20, and the display device storage unit 33 stores the electronic book 60. The electronic display 60 can be viewed using the book display device 30 including the operation display unit 32 that displays various information and the viewer application 50 that converts the electronic book 60 and displays it on the operation display unit 32. A basic character that is a book display program, in which basic characters that are frequently used and a management code that identifies the basic characters are registered in the viewer application 50 of the book display device 30, and font data 53 corresponding to the basic characters is associated with the basic characters. A table 52, a special character that is a character that is not a basic character of the document data 40 extracted based on the basic character table 52, and a management code for identifying the special character. The book character information 62 of the electronic book 60 composed of the management code corresponding to the character group of the document data 40 is browsed based on the special character table 64 created by associating the typeface data 65 corresponding to the special character. By executing the step of converting into a possible character group, the file size of the electronic book 60 can be suppressed, and an electronic book display program that can efficiently display the electronic book 60 including special characters can be provided.

  Specifically, the electronic book display program can be provided from the distribution server 20 via the Internet line 3.

  In the book creation process of the book creation device 10, the document character information 62 of the electronic book 60 is created with a management code, and the book display process of the book display device 30 reads the management code of the document character information 62. The code is not limited to the management code, and may be a JIS code, Unicode, glyph code, or the like.

Next, another example of a book display process for enabling the electronic book 60 to be browsed by the viewer application 50 in the book display device 30 will be described with reference to FIG.
FIG. 11 shows a flowchart of the book display processing operation in the second embodiment.
The same components as those in the first embodiment are given the same reference numerals, and detailed description thereof is omitted.

  First, when the user selects one electronic book 60 displayed in the book list 312 on the electronic book selection screen 310 and presses the book name, as shown in FIG. 11, the display device control unit of the book display device 30 is displayed. In response to the instruction 36, the viewer application 50 starts a book display process and reads the selected electronic book 60 stored in the display device storage unit 33 (step S401). Here, the viewer application 50 reads the management code of the document character information 62 one character at a time.

  Then, the viewer application 50 determines whether or not the read management code is 1000 or less (step S402). If the read management code is 1000 or less (step S402: Yes), the viewer application 50 determines that the read management code is a basic character, and refers to the basic character table 52 of the viewer application 50 (step S403). ).

  Thereafter, the viewer application 50 acquires the character corresponding to the read management code from the basic character table 52 (step S405), and temporarily stores the acquired character in the memory (step S406).

  On the other hand, if the read management code is not 1000 or less in step S402 (step S402: No), the viewer application 50 determines that the read management code is a special character, and the special character table 64 of the electronic book 60. Is referred to (step S404). Then, the viewer application 50 acquires a character corresponding to the read management code from the special character table 64, and temporarily stores the acquired character in the memory.

  Thereafter, the viewer application 50 determines whether or not the management codes for the number of characters that can be displayed on the operation display unit 32 have been read from the document character information 62 of the electronic book 60 (step S407).

  If the management code for the number of characters that can be displayed on the operation display unit 32 has not been read (step S407: No), the viewer application 50 returns the process to step S401 and starts the operation display unit from the document character information 62 of the electronic book 60. The processing is repeated until the management codes for the number of characters that can be displayed in 32 are read.

  On the other hand, if the management code for the number of characters that can be displayed on the operation display unit 32 has been read in step S407 (step S407: Yes), the viewer application 50 selects the characters temporarily stored in the memory and the selection-set characters. Based on the X font (X font data 53a, 65a), a font character that can be viewed on the operation display unit 32 is created (step S408).

  Then, the viewer application 50 displays the electronic book display screen 320 on which the electronic book 60 can be browsed on the operation display unit 32 (step S409), and ends the book display process.

  When the user presses the page return button 322 or the page feed button 323 on the electronic book display screen 320, the viewer application 50 starts the book display process and updates the content displayed on the operation display unit 32.

  In this way, the electronic book 60 stored in the display device storage unit 33 of the book display device 30 is displayed on the operation display unit 32 of the book display device 30 using the viewer application 50.

  As described above, in the book display device 30, it is determined whether the reference character table 52 or the special character table 64 is referred to by the management code of the document book information 62 for the book display processing that enables the electronic book 60 to be browsed. Thus, the viewer application 50 can shorten the time for converting the book character information 62 of the electronic book 60 into a viewable character group, and can efficiently display the electronic book 60 including special characters.

  Specifically, the management code is set so that the serial numbers are in order according to the frequency of use, so that the book character information 62 of the electronic book 60 is managed instead of the JIS code by the book creation processing of the book creation device 10. Created with code.

  Then, the viewer application 50 determines whether the management code of the book character information 62 is the management code of the basic character table 52 or the management code of the special character table 64, so that either the basic character table 52 or the special character table 64 is determined. Can be determined.

  Therefore, the viewer application 50 can shorten the time required for processing when referring to the basic character table 52 and without the corresponding management code as compared with the case of referring to the special character table 64.

  In addition, since the book character information 62 of the electronic book 60 is composed of a management code, it is simply encrypted and difficult to browse outside the viewer application 50, and unauthorized use of the electronic book 60 can be prevented. .

  Therefore, by setting the management code, it is possible to shorten the time for the viewer application 50 to convert the book character information 62 into a viewable character group, and to efficiently display the electronic book 60 including special characters.

  In the book display process of the viewer application 50, if the management code read from the book character information 62 of the electronic book 60 is 1000 or less, the basic character table 52 is referred to. A specific range in the management code of the character table 52 or the special character table 64 may be referred to.

  For example, in the book display process of the viewer application 50, if the management code read from the book character information 62 is “0981”, the viewer application 50 has a range of management codes 901 to 1000 in the basic character table 52. You may make it refer.

  Thus, by referring to a specific range in the management code of the basic character table 52 or the special character table 64 by the management code, it is possible to shorten the time required for the processing that enables the viewer application 50 to view the electronic book 60. .

  In each of the above-described embodiments, the number of characters registered in the basic character table 52 is 1000 characters, and the number of characters registered in the special character table 64 is 100 characters. However, the present invention is not limited to this.
