  An electronic book display device according to an embodiment of the present invention will be described. FIG. 1 is an explanatory diagram showing a connection example of the electronic book display device 2 according to the embodiment of the present invention.

  As shown in FIG. 1, an electronic book display device (electronic book display device) 2 is connected to a data providing server 1 that provides data of an electronic book via a communication network 3.

  The electronic book display device 2 is, for example, a mobile phone, a personal computer, or an electronic book dedicated terminal.

  The data providing server 1 electronically transmits electronic book data including electronic book text data (text data) and correlation diagram data (correlation diagram data) indicating the relationship between characters in the text via the communication network 3. It transmits to the book display device 2.

  The electronic book data will be described. FIG. 2 is an explanatory diagram illustrating a configuration example of electronic book data. As shown in FIG. 2, the electronic book data is text data of text (for example, equivalent to text of one page in a normal book) displayed on one screen in the display means (not shown) of the electronic book display device 2. And correlation diagram data associated with the sentence data. The display means is realized by, for example, a liquid crystal display installed in a mobile phone or an electronic book dedicated terminal, or a display device connected to a personal computer.

  In the text data, page numbers are set according to the order of display on the display means. Specifically, for example, the page number “1” is set for the text data of the text displayed first in one electronic book, and the page number “n” is set for the text data of the text displayed nth. The page number “z” is set in the sentence data of the sentence that is set and displayed last. That is, the electronic book data includes text data in which page numbers “1” to “z” are set.

  The sentence data and the correlation diagram data are associated with each other by, for example, a page number. Note that the correlation diagram data may be associated with each piece of text data, or the correlation diagram data may be associated with all the text data. In this example, description will be made assuming that the correlation diagram data is associated with some text data.

  The correlation diagram data is, for example, data for displaying on the display means of the electronic book display device 2 a screen (correlation diagram) showing the relationship between a plurality of characters in the sentence of the associated sentence data. The same page number as the text data is set. Specifically, for example, there are JPEG (Joint Photographic Experts Group) format image data, a program written in Java (registered trademark) language for displaying a correlation diagram on the display means, and the like.

  The correlation diagram data includes the relationship between a plurality of characters in the text of the text data associated with the correlation diagram data, and text data having a page number smaller than the page number set in the correlation diagram data. This is difference data or replacement data with relations between a plurality of characters in a sentence. It is assumed that the correlation diagram data includes information indicating whether the data is difference data or replacement data.

  The correlation diagram data of the difference data will be specifically described. For example, the correlation diagram data is associated with the text data of page numbers “n−1”, “n”, and “n + 1”, and the character “A” appears in the text of the text data of page number “n−1”. In addition, the character “B” appears in addition to the character “A” in the text of the text data of the page number “n”, and the character “A” and the character appear in the text of the text data of the page number “n + 1”. When the character “C” appears in addition to the character “B”, the correlation diagram data associated with the text data of the page number “n−1” is the correlation where the character “A” appears. This is data for displaying the figure on the display means.

  Further, the correlation diagram data of the difference data associated with the text data of the page number “n” is for displaying on the display means a correlation diagram indicating the relationship between the character “B” and the character “A”. It is data. The correlation diagram data associated with the sentence data of page number “n + 1” is for displaying the correlation diagram indicating the relationship between the character “C” and the character “A” and the character “B” on the display means. It is data of.

  Further, the correlation diagram data of the replacement data will be specifically described. For example, the correlation data is associated with the text data of page numbers “n” and “n + 1”, the character “A” appears in the text of the text data of page number “n”, and the page number “n + 1”. When only the character “B” appears in place of the character “A” in the text of the text data, the correlation diagram data associated with the text data of the page number “n” is the character “A”. Is displayed on the display means, and the correlation diagram data associated with the text data of the page number “n + 1” is data for displaying only the character “B” on the display means.

  FIG. 3 is a block diagram illustrating a configuration example of the electronic book display device 2. As shown in FIG. 3, the electronic book display device 2 includes a data transmission / reception unit (data input unit) 21, a data analysis unit 22, a text data reconstruction unit (text display control unit) 23, a text display unit 24, and a text storage unit. (Text data storage means, storage means) 25, correlation diagram assembly unit (correlation diagram display control means) 26, correlation diagram display unit 27, correlation diagram storage unit (correlation diagram storage means, storage means) 28, key input unit (instruction Input means) 29 and a key input analysis unit 30.

  The data analysis unit 22, the text data reconstruction unit 23, the correlation diagram assembly unit 26, and the key input analysis unit 30 are realized by, for example, a CPU that executes processing according to program control.

  The data transmission / reception unit 21 requests the data providing server 1 to transmit electronic book data via the communication network 3 in accordance with an instruction input to the key input unit 29 by the user. Further, the data transmitting / receiving unit 21 receives the electronic book data transmitted from the data providing server 1 via the communication network 3.

  The data analysis unit 22 inputs text data of the electronic book data to the text data reconstruction unit 23 and inputs correlation diagram data to the correlation diagram assembly unit 26.

  The text data reconstruction unit 23 recognizes the page number set in the text data based on the page number set in the text data input by the data analysis unit 22, and writes the text based on the text data in the order of the page numbers. It is displayed on the display unit 24 (specifically, the area for displaying the text in the display screen of the display means). Further, the text data reconstruction unit 23 causes the text storage unit 25 to store text data based on the page number set in the text data input by the data analysis unit 22.

  The correlation diagram assembling unit 26 recognizes the page number set in the correlation diagram data based on the page number set in the correlation diagram data input by the data analysis unit 22, and the sentence data in which the same page number is set. When a sentence based on the correlation diagram data is displayed on the sentence display unit 24, a correlation diagram based on the correlation diagram data is displayed as a correlation diagram display unit (specifically, for displaying a correlation diagram in the display screen of the display means). (Region) 27 is displayed. Further, the correlation diagram assembling unit 26 stores the correlation diagram in the correlation diagram storage unit 28 in association with the page number set in the correlation diagram data input by the data analysis unit 22. FIG. 4 is an explanatory diagram showing correlation diagrams accumulated in the correlation diagram storage unit 28. As shown in FIG. 4, correlation diagrams are accumulated in the correlation diagram storage unit 28 in order from the page number “1”.

  The operation of the correlation diagram assembly unit 26 will be specifically described. For example, a correlation diagram in which the character “A” appears as a correlation diagram based on the correlation diagram data of the page number “n−1” (correlation diagram of the page number “n−1”) has already been accumulated in the correlation diagram storage unit 28. If the correlation diagram data of the page number “n” is differential data in which the character “B” newly appears, the correlation diagram assembling unit 26 uses the page number as the correlation diagram of the page number “n”. The correlation diagram in which the character “B” appears in addition to the character “A” appearing in the correlation diagram of “n−1” (that is, the character “A”, the character “B”, and the character “A”) And the character “B” (specifically, for example, a correlation diagram indicating that each character is connected by an arrow) is generated, and the generated correlation diagram is displayed as a correlation diagram. Displayed on the unit 27 and accumulated in the correlation diagram storage unit 28That is, the correlation diagram assembling unit 26 generates a correlation diagram in which new characters based on the correlation diagram data of the difference data are added to the correlation diagram already accumulated in the correlation diagram storage unit 28 and generates the correlation diagram display unit 27. And stored in the correlation diagram storage unit 28.

  Further, for example, a correlation diagram in which the character “A” appears as a correlation diagram based on the correlation diagram data of the page number “n−1” (correlation diagram of the page number “n−1”) has already been stored in the correlation diagram storage unit 28. When the correlation diagram data of the page number “n” is replacement data in which the character “B” newly appears when stored, the correlation diagram assembling unit 26 uses the correlation diagram data of the page number “n” as a correlation diagram. Instead of the character “A” appearing in the correlation diagram of the page number “n−1”, a correlation diagram in which the character “B” appears is generated and displayed on the correlation diagram display unit 27. Accumulate. That is, the correlation diagram assembly unit 26 generates a new correlation diagram based on the correlation diagram data of the replacement data and displays it on the correlation diagram display unit 27 regardless of the correlation diagrams already accumulated in the correlation diagram storage unit 28. And stored in the correlation diagram storage unit 28.

  The key input unit 29 is realized by, for example, a plurality of buttons, and specifically includes a button corresponding to page turning and a button corresponding to page return. Based on the operation performed on the key input unit 29 by the user, the key input analysis unit 30 has operated the button corresponding to page turning (that is, the page turning operation has been performed), or returns to the page. It recognizes whether the corresponding button has been operated (that is, a page return operation has been performed). Note that the key input unit 29 is also operated by the user at the start of displaying a text or correlation diagram based on the electronic book data.

  When the key input analysis unit 30 recognizes that the page turning operation has been performed, the key input analysis unit 30 converts the text currently displayed on the text display unit 24 to the data transmission / reception unit 21 via the communication network 3. Requests transmission of electronic book data in which the page number (for example, n + 1) next to the page number (for example, n) set in the corresponding text data is set.

  Further, when the key input analysis unit 30 recognizes that a page return operation has been performed, the text data reconstruction unit 23 deletes the currently displayed text from the text display unit 24 and accumulates it in the text storage unit 25. The page number (for example, n-1) before the page number (for example, n) set in the sentence data according to the sentence currently displayed on the sentence display part 24 among the sentence data currently set is set. The sentence display unit 24 displays a sentence based on the written sentence data.

  Further, when the key input analysis unit 30 recognizes that a page return operation has been performed, it corresponds to the same page number as the page number set in the sentence data corresponding to the sentence currently displayed on the sentence display unit 24. If the attached correlation diagram is accumulated in the correlation diagram storage unit 28 and displayed on the correlation diagram display unit 27, the correlation diagram assembly unit 26 deletes the correlation diagram from the correlation diagram display unit 27, and the correlation diagram is displayed. Among the correlation diagrams stored in the storage unit 28, a correlation diagram of a page number (for example, n-1) before the page number (for example, n) of the correlation diagram currently displayed in the correlation diagram display unit 27 is shown. It is displayed on the correlation diagram display unit 27.

  Then, for example, the character “B” appears in the correlation diagram of the page number “n”, and the character “B” does not appear in the correlation diagram of the page number before the page number (for example, n−1). In this case, if the page return operation is performed while the correlation diagram of the page number “n” is displayed on the correlation diagram display unit 27, the character “B” is deleted from the display area of the correlation diagram display unit 27. The

  The electronic book display device 2 is an electronic book display program that causes a computer to display the contents of an electronic book, which is a digitized book, on a display unit. Display means prepared for each range displayed on one screen, the text of the book text converted into data for each range, and a correlation diagram showing the relationship between the characters in the range and the other characters Including correlation diagram data prepared in accordance with the text in the range for display on the computer, and an instruction input process for inputting the user's instruction to the computer and the electronic book data prepared for each range. Data input process, text display control process for displaying text based on text data on display means, and correlation chart for generating correlation diagram based on correlation diagram data and displaying on display means Control process, and in the text display control process, in accordance with the instruction input in the instruction input process, the display unit displays a sentence based on the sentence data included in the electronic book data input in the data input process. In the correlation diagram display control process, an electronic for displaying on the display means a correlation diagram based on the correlation diagram data included in the data of the electronic book input in the data input process according to the instruction input in the instruction input process Equipped with a book display program.

  Next, operation | movement of the electronic book display apparatus 2 of embodiment of this invention is demonstrated. FIG. 5 is a flowchart showing the operation of the electronic book display device 2 according to the embodiment of the present invention.

  When the user operates the key input unit 29 to start displaying a text or correlation diagram based on the electronic book data, the key input analysis unit 30 checks whether the text data is accumulated in the text storage unit 25. (Step S101).

  When no text data is stored in the text storage unit 25 (N in step S101), the key input analysis unit 30 sends a page number “1” to the data transmission / reception unit 21 via the communication network 3 to the data providing server 1. Is requested to transmit the electronic book data set (step S102).

  The text data reconstruction unit 23 is included in the received electronic book data when the data transmission / reception unit 21 receives electronic book data in which the page number “1” is set in the data providing server 1 via the communication network 3. A sentence based on the sentence data is displayed on the sentence display unit 24. Moreover, the text data reconstruction unit 23 accumulates the text data in the text storage unit 25 (step S103).

  The correlation diagram assembling unit 26 is included in the received electronic book data when the data transmitting / receiving unit 21 receives the electronic book data in which the page number “1” is set in the data providing server 1 via the communication network 3. A correlation diagram based on the correlation diagram data generated is generated and displayed on the correlation diagram display unit 27. The correlation diagram assembling unit 26 accumulates the generated correlation diagram in the correlation diagram storage unit 28 (step S104).

  In addition, when the text data is stored in the text storage unit 25 (N in Step S101), the key input analysis unit 30 causes the text data reconstruction unit 23 to store text data stored in the text storage unit 25 (N in Step S101). For example, of the page numbers “n-5” to “n”), the sentence display unit 24 displays a sentence based on the sentence data in which the largest page number (for example, the page number “n”) is set (step S105).

  Then, the correlation diagram assembling unit 26 has the largest page number (for example, page numbers “n-5”, “n−1”, “n”) stored in the correlation diagram storage unit 28. For example, the correlation diagram of the page number “n”) is displayed on the correlation diagram display unit 27 (step S106).

  The text data reconstruction unit 23 stores the page number of the text that the text data reconstruction unit 23 previously displayed on the text display unit 24 in the text storage unit 25, and the text and the correlation diagram are based on the page number. It may be configured to be displayed.

  When the key input unit 29 is operated (Y in step S107), the key input analysis unit 30 recognizes whether a page feed operation or a page return operation is performed (step S108).

  When the key input analysis unit 30 recognizes that the page input operation has been performed on the key input unit 29 (Y in step S108), the key input analysis unit 30 sends the data transmission / reception unit 21 to the data providing server 1 via the communication network 3 at present. Requests transmission of electronic book data in which the page number (for example, n + 1) next to the page number (for example, n) set in the sentence data corresponding to the sentence displayed in the sentence display unit 24 is set (for example, n + 1). Step S109).

  The text data reconstruction unit 23 is included in the received electronic book data when the data transmitting / receiving unit 21 receives the electronic book data with the page number “n + 1” set from the data providing server 1 via the communication network 3. A sentence based on the sentence data is displayed on the sentence display unit 24. Moreover, the text data reconstruction unit 23 accumulates the text data in the text storage unit 25 (step S110).

  Then, when the data transmitting / receiving unit 21 receives the electronic book data in which the page number “n + 1” is set from the data providing server 1 via the communication network 3, the correlation diagram assembling unit 26 correlates with the received electronic book data. When diagram data is included, a correlation diagram based on the correlation diagram data is generated and displayed on the correlation diagram display unit 27. The correlation diagram assembling unit 26 superimposes characters appearing on the basis of the correlation diagram data on the correlation diagram currently displayed on the correlation diagram display unit 27 if the correlation diagram data is the correlation diagram data of the difference data. If a correlation diagram is generated, and the correlation diagram data is the correlation diagram data of the replacement data, a correlation diagram based on the correlation diagram data is newly generated and replaced with the correlation diagram currently displayed on the correlation diagram display unit 27 It is displayed on the correlation diagram display unit 27. Further, the correlation diagram assembling unit 26 accumulates the generated correlation diagram in the correlation diagram storage unit 28 (step S111).

  When the key input analysis unit 30 recognizes that the page input operation has been performed on the key input unit 29 (N in step S108), the key input analysis unit 30 displays the current text display unit 24 on the text data reconstruction unit 23. The sentence display unit 24 displays a sentence based on the sentence data in which the page number (for example, n-1) before the page number (for example, n) set in the sentence data corresponding to the sentence is set (step S112). ).

  The key input analysis unit 30 correlates the correlation diagram of the same page number (for example, page number “n”) as the page number set in the sentence data corresponding to the sentence currently displayed on the sentence display unit 24. If accumulated in the diagram storage unit 28 and displayed on the correlation diagram display unit 27, the correlation diagram assembly unit 26 deletes the correlation diagram from the correlation diagram display unit 27, and the correlation diagram storage unit before the correlation diagram. 28, the correlation diagram of the page number closest to the page number of the correlation diagram (for example, the correlation diagram of page number “n−1”) is displayed on the correlation diagram display unit 27 (the correlation diagram is displayed). Update) (step S113).

  As described above, in the present embodiment, when the user advances the text and the page input operation is performed on the key input unit 29, a correlation diagram corresponding to the text is displayed on the correlation diagram display unit 27. This makes it possible for the user to easily recognize changes in the characters.

  Moreover, the content of the book which is not represented by the text can be expressed with a correlation diagram using the correlation diagram.

  Further, since the correlation diagram can be generated using the correlation diagram data of the difference data, the amount of data to be transmitted to and received from the data providing server 1 and the storage capacity can be reduced as compared with the case where the difference data is not used. .

  In the embodiment described above, the electronic book display device 2 is configured to receive the data of the electronic book from the data providing server 1 via the communication network 3, but the data of the electronic book is stored. The electronic book data may be read from a storage medium such as a memory card, or the electronic book data may be received from another directly connected computer.

  In addition, the correlation diagram data includes information indicating a character appearing based on the correlation diagram data, and the data of the electronic book with one page number includes information indicating that one character does not appear thereafter, and data transmission / reception When the unit 21 receives the data of the electronic book, the data analysis unit 22 may be configured to delete the correlation diagram in which the one character appears from the correlation diagram storage unit 28. In the case of such a configuration, the accumulation amount of the correlation diagram storage unit 28 can be reduced.

  Further, the text display unit 24 and the correlation diagram display unit 27 may be realized by different liquid crystal displays and display devices, or may be different regions on the display screen of one liquid crystal display or one display device. . Further, it may be configured such that the sentence display state and the correlation diagram display state can be switched in accordance with a user instruction.
