Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. Needless to say, the contents of the present invention are not limited to the contents of the following embodiments.

[1. Entire system]
A system 1 including a terminal device (electronic book display device) capable of displaying an electronic book of the present invention will be described with reference to FIG. As shown in FIG. 1, an electronic book display device 10 capable of browsing and displaying an electronic book is connected to a management server 20 via a network NW.

The electronic book display device 10 is a terminal device used by a user, and is, for example, a tablet type. At this time, the electronic book display device 10 may be a dedicated terminal device capable of browsing the electronic book, or a tablet device on which a general OS such as Android, iOS, Windows, or Linux (registered trademark) operates, It may be one in which an application (viewer software) that can read electronic books is installed.

Further, in the present specification, for convenience of description, an electronic book display device capable of displaying an electronic book (electronic book data) is described as an electronic book display device 10, but a plurality of electronic book display devices themselves can be connected. Of course. For example, an application may be installed in the computer 15, or a display function of an electronic book may be provided by the WEB service.

The management server 20 is a server that manages and provides electronic books. It is managed and operated by an electronic book provider, and the electronic book is provided as content to the electronic book display device 10. Various companies such as publishers, agency companies, bookstores, and software companies can be considered as the e-book provider.

Here, the electronic book and electronic book data referred to in this specification refer to contents that can be browsed on the electronic book display device 10. For example, it is content data such as PDF (Portable Document Format), HTML (Hyper Text Markup Language), XML (Extensible Markup Language), SGML (Standard Generalized Markup Language), EPUB, text file, and document file.

Further, when displaying an electronic book on the electronic book display device 10, page turning, enlargement/reduction display, a search function, and a bookmark function can be realized. Further, other contents on the Internet may be displayed by using the link function, or images, voices, moving images, and the like may be displayed together. Such a composite content is called an electronic book.

The management server 20 may have a different server configuration for each function. For example, the server for storing the electronic book and the server for charge management may be different, and the data of the electronic book may be prepared for each electronic book business operator, for example, for each publisher.

Further, the electronic book display device 10 may be a device that can display an electronic book stored in the device itself, for example, without connecting to the network. A device capable of displaying an electronic book stored in advance, a USB memory, or an electronic book stored in an SD card (registered trademark) may be used.

[2. Functional configuration]
Next, the functional configuration of the electronic book display device 10 (FIG. 2) will be described with reference to the drawings.

The electronic book display device 10 includes a control unit 100, a storage unit 200, a communication unit 300, a display unit 400, and an operation input unit 500.

The control unit 100 is a functional unit for controlling the entire electronic book display device 10. The control unit 100 realizes various functions by reading and executing various programs stored in the storage unit 200, and is configured by, for example, a CPU (Central Processing Unit).

The storage unit 200 is a functional unit in which various programs necessary for the operation of the electronic book display device 10 and various data are stored. The storage unit 200 is composed of, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

Here, as shown in FIG. 3, the storage unit 200 stores an electronic book file 210 and user additional information 220, and stores a library display program 230 and an electronic book display program 240 as programs. Has been done.

Here, the electronic book file 210 and the user additional information 220 can be managed for each user, and a plurality of them may be stored. Further, the electronic book file 210 can store a plurality of files, and the files related to the electronic book that can be browsed by the user are stored.

The electronic book file 210 is a file prepared by an electronic book (content) provider such as a publisher. It may be stored in advance or may be received from the management server 20 via the network NW.

An example of the data structure of the electronic book file is shown in FIG. As shown in FIG. 4, the electronic book file includes a book identification code, book information, copy data, electronic book data, publisher addition information, and page number correspondence information.

The book identification code is identification information for identifying an electronic book. As the book identification code, a system unique code may be added anew, or a code uniquely determined in advance (for example, ISBN code, magazine code) may be used.

If a common code such as an ISBN code or a magazine code is used, there is an advantage that data can be shared even in different systems. In addition, there is an advantage that it is not necessary to add a code again.

As the book information, information about electronic books is stored, and various information such as a book name, an author name, an issue date, a printing plate, and a price is stored. Note that these pieces of information may not be included in the electronic book data, and other databases may be referred to from the ISBN code or the like.

The calligraphic image file is an image file used when displaying a list of electronic books and when displaying the electronic drawing of an electronic book as necessary in a browsing process such as displaying a table of contents. In the present embodiment, as an example, an image file (JPG file) such as “900162011.jpg” is stored. The calligraphic image file may not be included in the electronic book file and may be generated each time from the book file.

The electronic book data stores data regarding an electronic book used when displaying as an electronic book. The book file may be a PDF file as in this embodiment, or a general-purpose format such as GIF format, ePUB format, or HTML format may be used.

The publisher addition information is information added by a publisher or the like who is a provider of the electronic book file. As the additional information, a page number (P number), position information indicating a position in the page, and a link destination stored in the additional information are stored.

Here, the page number may be stored as a data page number described later or as a book page number. Further, the position information is stored as a coordinate position of the page in the present embodiment, but may be stored at a character position (for example, a row/column position).

The link destination is information for indicating the behavior when the user selects the additional information. For example, if the position is stored as “P.105-(200, 10)” as shown in FIG. 4, it is stored that the jump process is performed at a different position in the electronic book data. If a file name (data name) such as “120820gk231.jpg” is stored, the file (data) in the content will be displayed/played.

Other than that, for example, by storing a link destination that starts with "http://", an external WEB page is displayed, or "xxx@xxx.ne.jp" is stored and the address is stored, The behavior may be such that an email is sent to the destination.

The page number correspondence information indicates the correspondence between the file page number, which is the physical page number in the electronic book data, and the book page number, which is the logical page number displayed and managed as the electronic book, corresponding to the attribute. I remember.

Here, the electronic book has an attribute for each of a plurality of areas as in a paper medium book, and the concept of a plurality of page numbers appears. That is, in the case of an electronic book, it may not be simply a serial number from the beginning. For example, the table of contents and the index may have different page numbers from the text. In addition, when there is a separate volume such as an appendix, in the electronic book data (for example, PDF file), pages are continuous, but different page numbers are assigned.

These areas such as a table of contents, an index, and a body are used as attributes, and page numbers (page notations) are associated with each attribute (area). As a result, the user can search or jump by the page number displayed in the electronic book data.

Further, the book page number is not assigned to some pages in the case of books. In such a case, the book page number may be set to "none" when it is hidden.

In addition, it is sufficient to store necessary attributes. At least the text should be stored. For example, if this function is not used by an electronic book, the text may have the same file page number and book page number.

Note that in the present embodiment, the electronic book file 210 is stored together, but it may be stored as a separate file.

The user additional information 220 is a file that stores various additional information that the user can add to the electronic book. The user additional information 220 stores memo data information 220a, handwriting data information 220b, marker data information 220c, camera data information 220d, and bookmark data information 220e. In the present embodiment, the five types of user additional information 220 will be described. Of course, it is sufficient to combine necessary data among these data.

An example of the data structure of the memo data information 220a is shown in FIG. Specifically, the page number, position information, size information, color information, memo state, and memo data of the electronic book data are stored in association with the book identification code.

As the page number, the page number in the electronic book data is stored, and the file page number or the book page number described above is stored. For example, when the file page number is stored, it is converted into the book page number and displayed in the screen display described later. If the book page number is stored, it is converted into a file page number and used when switching pages by a link function or the like. In other words, either one or both may be stored. In the present embodiment, for convenience of description, the description will be given below as “page number”.

The position information and the size information store the place where the memo is attached. In the present embodiment, the coordinate position within the page is stored, and “position information” as the coordinate position where the memo is pasted and “size information” indicating the size of the memo are stored. The memo of this embodiment is characterized in that its size can be changed. In other words, the size of the memo can be increased or decreased by the user's operation.

In this embodiment, the position information and the size information are separated in the user additional information 220, but they may be the same. That is, the upper left and lower right coordinates may be stored as the position information.

The color information is information indicating the color of the memo. A plurality of colors are assigned as the color information, and the color information designated by the user (for example, light yellow in “3” or the like) is stored. Here, in the electronic book display device 10 according to the present embodiment, when a dark color is selected, a bright color is selected for the text displayed as a memo. For example, when the color of the memo is “light yellow”, the character is displayed in “black”, but when the color of the memo is “dark brown”, the character is “white”.

The memo state is information indicating whether the memo is displayed or displayed as an icon. When displayed as a memo, it is stored as "display", and when displayed as an icon, it is stored as "minimum". In addition, when it is desired to hide the memo, it may be “non-display”.

Here, the icon display means a status display for showing that a memo is attached. A character, a symbol, or a picture indicating that there is a memo may be displayed, or a reduced memo of the memo may be displayed. The minimum display in this embodiment includes such various representation methods.

The memo data stores the memo data input by the user. For example, text data and handwritten image data are stored. When the memo is a hand-drawn image, it is drawn in the memo area, unlike hand-drawn data described later.

FIG. 5B shows an example of the data structure of the handwriting data information 220b. Specifically, a page number, position information, size information, and handwriting data are stored in association with the book identification code.

Here, the handwritten data information 220b stores the input handwritten data. Here, in the present embodiment, the hand-drawn data can be stored as vector data and edited by the user later. Various information such as the position, size, color, and thickness of the line drawing is stored in the handwriting data, and by using the handwriting data, it is possible to superimpose it on the displayed electronic book. Become. Note that hand-drawn data may be recognized and stored as character information.

An example of the data structure of the marker data information 220c is shown in FIG. Specifically, a page number, position information, color information, type, memo state, and memo data are stored as marker data in association with the book identification code.

The marker data stored in the marker data information 220c is information stored when a marker is attached to the characters of the displayed electronic book. In the case of the present embodiment, the position of the marker is stored at the coordinates within the page, but it may be stored at the character position.

Further, the thickness of the marker may be an arbitrary thickness, or the size may be automatically changed according to the size of the displayed text. For example, if the character size is large, the marker may be thick, and if it is small, the marker may be thin.

Further, the marker of the present embodiment stores color information and type. The color information stores the color of the marker and can be changed later by the user. In addition, “transparent” and “filling” are stored as types. In the case of transparency, the user can check the character under the marker, but in the case of "fill", the transparency is 0%, and the user cannot check the character underneath.

In addition, a memo can be attached to the marker. The memo attached to the marker is stored as a “memo state”. At this time, it is stored in the "memo state" whether to display with the marker or to display the icon.

An example of the data structure of the camera data information 220d is shown in FIG. Specifically, a book identification code, a page number, position information, size information, an image state, and camera data (image data) are stored.

Here, the page number, position information, and size information have the same contents as the other user additional information described above. The image state is also the same as the memo state, for example.

Image data is stored in the camera data information 220d. As the image data, it is possible to store an image stored in advance or downloaded image data. Further, when the electronic book display device 10 has a camera function, an image captured by the camera function may be used.

The bookmark data information 220e stores the bookmark attached by the user as bookmark data in order to use the bookmark function. For example, as shown in FIG. 6, the page number and the bookmark type are stored in association with the book identification code.

By using the bookmark function, the user can directly display (jump) the page. Here, the type of bookmark is stored in the bookmark data information 220e of the present embodiment.

Depending on the type of bookmark, the user can classify and attach a plurality of bookmarks. Further, when the bookmark is displayed, it is possible to divide the color for each bookmark type, display a symbol, and display a character.

The user additional information 220 may be generated by a person other than the user. For example, in the case of an educational institution, an educational institution staff member, a teacher, a professor, or other instructor may create it beforehand and download it to the electronic book display device 10. Further, the user himself/herself may perform the import/export to input/output the user additional information generated by another device or generated by another user.

The library display program 230 is a program for displaying a list of electronic book files stored in the electronic book display device 10. The library display program 230 is read and executed by the control unit 100, so that the electronic book display device 10 displays The library display function is realized.

The electronic book display program 240 is a program for displaying electronic book data, and is read by the control unit 100 and executed to realize an electronic book display function on the electronic book display device 10.

Here, the electronic book display function can realize a general function realized by a so-called electronic book viewer (for example, one-page/plural page display of an electronic book, a page feed function, a jump function, etc.). Since each function generally realized by such an electronic book viewer is a conventional function, detailed description in this specification will be omitted.

The communication unit 300 provides a network interface used when the electronic book display device 10 is connected to the network NW. The communication unit 300 can use, for example, a wireless LAN realized by IEEE 802.11a/b/g/n or the like, a wired LAN, an interface such as a mobile phone network using an LTE line.

The display unit 400 is a functional unit for displaying various kinds of information, and is composed of, for example, an LCD or an organic EL display. Further, it may be displayed on an external monitor via HDMI (registered trademark) or USB.

The operation input unit 500 is a functional unit for detecting an operation input from the user. For example, it may be realized by a touch panel, or may be realized by a hardware key or each input device such as a keyboard, a mouse, and a voice input device.

Alternatively, the display unit 400 and the operation input unit 500 may be integrally formed and provided as a touch panel display in the electronic book display device 10.

The image capturing unit 600 is a functional unit for capturing an image, and is configured by, for example, a camera using a CCD element. The captured image is stored in the storage unit 200 as image data. Further, the image data can be used as a camera memo and the user additional information 220 (camera data information 220d).

The functional configuration of the electronic book display device 10 described above is an example, and it is not always necessary to have all the functional units. For example, the communication unit 300 is unnecessary if it does not have a communication function, and the imaging unit 600 is unnecessary if it does not have a camera function.

[3. Process flow]
Next, the flow of processing in this embodiment will be described using the flowchart shown in the figure.

[3.1 Library Display Processing]
First, the library display process will be described with reference to FIG. The library display processing first displays a list of stored electronic books (step S102). That is, each of the electronic book files 210 stored in the electronic book display device 10 is displayed like a bookshelf. At this time, a writing image is displayed based on the writing image data to represent the electronic book. Note that the list display does not necessarily have to be displayed like a bookshelf, and for example, only electronic book names may be displayed as a list.

Subsequently, when the user selects the electronic book (file) (step S104; Yes), the electronic book is displayed. Specifically, the electronic book data included in the selected electronic book file is displayed so that the user can browse. Here, when the browsing history is used as the displayed page, that is, when the previously displayed page position is used, the final browsing position is set as the display position and the electronic book display process is executed (step S114). Yes → step S116 → step S120).

When the browsing history is not used or when the final browsing position is not stored, the display position is displayed from the first page (step S114; No → step S120).

When the display of my data is selected without selecting the electronic book, the my data list display processing is executed (step S104; No→step 106; Yes→step S108).

Here, the my data display is a function of displaying a list of the user additional information stored in the user additional information 220 so that the user can use it. It is possible to sort and display a list for each type of user additional information. For example, the list display can be sorted and displayed for each type, attribute, update date, and book.

For example, when the bookmark data is selected as the user additional information, the bookmark data (book data, page position in the book data) stored in the bookmark data information 220e is displayed in a list. Further, at this time, it is possible to sort by bookmark type or by book data. If the date when the bookmark is stored (update date) is also stored, the bookmarks can be sorted in the order of update date. Further, the sort may be in ascending order/descending order, and if it is a bookmark, it may be displayed in order from the selected type (color).

In addition, in the case of handwritten data, a preview display may be displayed together with the page display based on the handwritten data stored in the handwritten data information 220b. It is also possible to display an icon combined with the color information of the memo stored in the information 220a.

When the displayed user additional information is selected by the my data display process (step S110; Yes), the display position is set based on the page number of the selected user additional information. Then, the electronic book display process is executed based on the electronic book data corresponding to the book identification code stored in the user additional information and the set display position, and the electronic book is displayed.

[3.2 Electronic Book Display Processing]
Subsequently, the electronic book display process will be described with reference to FIG. First, by displaying the electronic book data, the user can browse the electronic book (step S202). Here, the page to be displayed displays the page number when the display position is set in the library display processing of FIG. 7, and displays the first page when the display position is not set. Further, the number of displayed pages may be one page at a time, or may be a two-page spread display. Further pages may be displayed.

Then, additional information display processing is executed (step S204). By executing the additional information display process, the publisher additional information and the user additional information are displayed on the electronic book. Here, the additional information display processing will be described with reference to FIG.

The additional information display process is a process of displaying the additional information selected by the user by the indicator display described later. Additional information will be displayed together with the currently displayed electronic book data. Also, when the additional information is not displayed, each function cannot be used.

For example, when a link is attached to the word "Fig. 1", and when the link information is "ON", the link information displayed in "Fig. 1" is selected to display the contents of Fig. 1. You can use the link function by displaying or jumping to the relevant place. However, when the link information is set to “OFF”, the identification display indicating the link is not displayed in “FIG. 1”, and even if the user selects “FIG. 1”, no operation is performed.

Specifically, all the additional information to be displayed can be turned ON/OFF in any combination. For example, if the link information is “ON”, link display is performed (step S302; Yes→step S304). If the marker is “ON”, the marker is displayed, that is, the marker is displayed based on the marker data stored in the marker data information 220c (step S306; Yes→step S308).

If the memo is “ON”, the memo is displayed (step S310; Yes→step S312). Specifically, the memo data is read from the memo data information 220a and displayed.

If the handwritten memo is “ON”, the handwritten memo is displayed (step S314; Yes→step S316). Specifically, the handwriting data is read from the handwriting data information 220b and displayed.

If the camera data is “ON”, the camera data is displayed (step S318; Yes→step S320). Specifically, the camera data (image data) is read from the camera data information 220d and displayed.

In this way, each additional information can be turned ON/OFF by the user in any combination.

By enabling the display ON/OFF described above, it is possible to use different e-books when the user wants to use the e-book peculiarly including the additional information and when he/she browses the page close to the paper medium without displaying the additional information. The user can choose.

The selection of this additional information is performed by the indicator display. Returning to the operation flow of FIG. 8, the explanation will be given. When the indicator is called (step S206; Yes), the indicator is displayed. The indicator display is a display for selecting whether or not to use (display) the additional information.

Then, when the indicator is selected (additional information is selected), the additional information display process is executed again based on the selected additional information (step S208→step S210→step S204). In the present embodiment, the indicator display is used for easy selection, but display/non-display (whether to use or not) may be selected on the setting screen or the like, for example.

Subsequently, in the electronic book display process of FIG. 8, when the indicator is not called and another operation is detected (step S212; Yes), it is determined whether or not the additional information is selected for the operation.

Here, when the additional information is not selected, it is determined that the normal electronic book operation process is performed, and the electronic book operation process corresponding to the operation is executed (step S214; No→step S250).

Here, as the electronic book operation, various operations such as page turning and returning by a slide operation and reduction/enlargement operation by a pinch-in and pinch-out operation are performed. Since these operations are the functions of the conventional electronic book viewer, description thereof will be omitted.

The present embodiment is characterized in that the operation different from the conventional one can be performed by the vertical swipe operation or the horizontal swipe operation in the page feed operation. Usually, in the case of an electronic book in the horizontal direction, a left-right swipe operation is performed, and on a screen such as a WEB page, an operation of switching pages is performed by a vertical swipe operation.

In the electronic book display device 10 of the present embodiment, even for an electronic book in the horizontal turning direction, the page turning operation can be performed in the vertical direction or the horizontal direction. This allows the user to switch pages by a plurality of operations.

When the additional information is selected, the additional information operation process is executed. The additional information operation process is a process performed when the additional information is specifically selected. For example, by tapping a memo, you can add notes or change the color. You can add a memo or change the color by tapping the marker. Further, when the marker is in the transparent state, it is possible to pull the marker in a darker state by pulling the markers in an overlapping manner.

In addition to this, various operations such as changing the size of memo/camera data (image), changing the position, minimizing the memo, and returning to the normal state are possible.

If a bookmark, which is one of the additional information, is selected, a process of adding a bookmark to the page is performed. At this time, the type of the bookmark can be selected, and the bookmark data stored in the bookmark data information 220e includes the page number and the bookmark type.

Further, even when the electronic book is displayed, the my data list display can be executed (step S222; Yes→step 224). Here, the operation is basically the same as the my data list display processing (step S108 in FIG. 7) executed in the library display processing, but the range of the user additional information displayed is different.

That is, in step S108 of FIG. 7, all the user additional information corresponding to the electronic book file stored in the electronic book display device 10 is targeted, whereas in step S224 of FIG. Only the user additional information corresponding to the stored electronic book data will be displayed.

Then, when the user performs an operation of ending the display of the electronic book (step S226; Yes), this processing is ended and the library display is returned to.

Hereinafter, examples of the present embodiment will be described based on a specific screen display example of the electronic book display device 10.

FIG. 10 is an example of a library display in which electronic books are displayed in a list. Calligraphic data is displayed in a matrix on a display simulating a bookshelf, and the user selects an electronic book that the user wants to browse. For example, in FIG. 10, the electronic book B100 is selected by the user. The display screen when selected is shown in FIG.

In FIG. 11, one page of electronic book data is displayed. In the display of the electronic book data, link information is displayed as additional information. For example, L100, L110, and L120 are displayed as the link information.

Here, the link information L100 and L110 and the link information L120 have different colors. This is to change the color depending on the type of link destination. There are various types of links, such as links within the same e-book (content), links to external sites (for example, WEB pages), links to other contents such as charts and videos, and links added by users. To be The color and display of the link can be switched according to the type of the link and the information of the link destination. In the present embodiment, the color is used for identification, but the display may be made using, for example, the shape, brightness, or symbol.

FIG. 12 is an example of a screen on which an indicator is displayed. As shown in FIG. 12, when the area of V100 is tapped, the indicator display N100 is displayed. The indicator display N100 shows additional information that can be displayed/hidden. For example, the region R100 shows a link, and when the link is selected, a check mark is displayed and the link is displayed on the electronic book. The link function can be used for the displayed part.

Further, the additional information that is not currently selected is grayed out, and it can be seen that it is not selected. For example, the marker in region R110 is not currently selected. Therefore, no marker is displayed on the electronic book.

Here, when the region R100 is selected again, the link is deselected this time to be hidden, and when the region R110 is selected, the marker is displayed this time. FIG. 13 shows the state at this time.

In FIG. 13, M100 and M110 are displayed as markers. Then, as shown in the region R100, the link is not displayed because the selection of the link is released. Further, since the marker M100 is a transmissive marker, the user can visually recognize the characters under the marker. On the other hand, since the marker M110 is not transparent, the character below cannot be visually recognized.

As described above, by selecting the additional information to be displayed using the indicator display N100, it is possible to switch display/non-display of arbitrary additional information. For example, the student can use it for learning by selecting an important part with a marker that does not penetrate and switching the display/non-display of the marker.

As described above, a plurality of additional information can be selected, and for example, as shown in FIG. 14, the link selected in R100 and the memo selected in R120 can be displayed together. The memo MM10 is displayed on the electronic book in a normal state.

The size of the memo MM10 can be changed (for example, FIG. 15) and the color can be changed (for example, FIG. 16). You can change the memo when you add it for the first time, or you can change the size, color, and content of the memo once added.

Further, as shown in FIG. 17, camera data may be pasted. In FIG. 17, the camera data CM10 is attached. With this, for example, it is possible for the user to photograph and paste what he/she actually needs. For example, in the case of a medical book, it is possible to paste the actual case and operation state, and in the case of a student, the contents of the blackboard can be photographed and pasted.

When this camera data is minimized, it may be displayed in a reduced size (CM12) as shown in FIG. If the reduced display is made, there is an advantage that the display is not disturbed and the contents can be easily confirmed.

FIG. 19 shows a state in which a handwritten memo is displayed. The handwritten memo HM10 is displayed overlaid on the electronic book. It is possible to change the line size and color of this handwritten memo later.

FIG. 20A is an example of a screen when the page preview is displayed at the bottom of the screen when the page switching operation is performed. In the area R200, the screen preview is displayed in R210, and the page number is displayed in the area R220 below the screen preview. Here, the displayed page number is the book page number. For example, as shown in FIG. 20, the page number is displayed as “iv” and “v” because it is the area of the table of contents up to the left two pages. The text starts from the third page from the left, and the page number is displayed from "1".

It should be noted that this page display can be switched to a display mode in which a two-page spread can be seen, as shown in FIG.

Next, FIG. 21 shows an example in which a bookmark is used as user additional information. FIG. 21 mainly shows the upper area of the display area of the electronic book display device 10. Here, when the user touches the bookmark mark SR10, the user additional information (bookmark data) regarding the bookmark can be added to the currently displayed page.

At this time, the type (color) can be set as an attribute of the bookmark or bookmark. For example, four colors are displayed in the region R300. Here, as shown in FIG. 21B, for example, when the user selects the second color from the left (for example, blue), the bookmark is selected in the selected type. Then, the display color of the bookmark mark SR10 having the same color is changed. As shown in FIG. 21(c), numbers or the like may be used instead of colors.

In addition, the selected bookmark color may be retained after the page transition, or may be returned to the initial color. The return timing may be a page transition or a timing when the type of user additional information is switched.

FIG. 22 is a diagram for explaining an example of displaying my data. When the operation of displaying the my data is performed while the electronic book is displayed, the my data is displayed as the area R400, and the user additional information corresponding to the displayed electronic book (electronic book data) is displayed as a list. To be done.

Here, it is possible to switch and display all the user additional information among the user additional information 220. As an example, FIG. 22 is displayed based on the bookmark data stored in the bookmark data information 220e.

Moreover, the user additional information can be freely sorted. By touching the sort order classification displayed in the region R410, the sort order can be switched. For example, in FIG. 22, the bookmark data is sorted in color order (bookmark type order). Thus, for example, the user can change the color (change the bookmark type) according to the degree of importance to display an important page.

In addition, the pages may be displayed in page order, or if the user additional information 220 stores the date and time when the user added the additional information, the user additional information 220 may be sorted in update date order.

Further, from the area R420, information regarding the page with the bookmark is displayed. For example, a mark indicating the color of the bookmark, a preview display of the page, the date on which the bookmark is added, the relevant portion (major item or middle item), and the page number are displayed.

Since this page number is a book page number, the display is easy for the user to understand. Further, instead of or in addition to the page preview, detailed item names, partial summary of the page, snippet display, etc. may be performed.

If the user additional information to be displayed is, for example, handwritten data, a handwritten memo may be displayed on the preview display. If it is memo data, the memo itself may be displayed instead of the page display. In addition, if it is camera data, an actual image may be displayed.

FIG. 23 is an example of a case where My Data is displayed on the library display screen. Although the my data is displayed in the area R500, the electronic books based on the user additional information displayed in the area R510 are a plurality of electronic books.

For example, the first and second books are electronic book “medical examination guides”, but the third book from the top is bookmark data of electronic books different from the “medical list”. In this way, by displaying a plurality of electronic books at once (list display by so-called skewering), the user can confirm the data according to the type of bookmark.

[5. E-book file creation]
The electronic book file described above can be generated by an electronic book file generation device. In particular, it is necessary to add the publisher addition information and the page number correspondence information in addition to the usual electronic book data.

The electronic book file generation device needs to generate the read electronic data into a data format that the electronic book display device 10 can read and display. In this case, for example, a PDF file is used to add the publisher addition information and the page number correspondence information.

As the publisher additional information, data is added so that an internal link within a page or an external link to an external site or the like can be identified. For example, a PDF is used to select a portion to which a link is to be added, and the information of the link destination is input. Then, different link information is added according to the link destination information. At this time, since the internal links are within the same electronic book file, if the page numbers are misaligned due to, for example, deletion or insertion of pages, relinking may be automatically performed.

The page number correspondence information sets a book page number for displaying a book for each attribute such as "table of contents", "text", and "index". Specifically, while displaying the PDF and checking the page, information such as where is the "table of contents" is added. Then, it is possible to set how to write the page notation for each attribute.

As described above, by reading and displaying the electronic book file generated by the electronic book file generating apparatus according to the present embodiment as the electronic book file 210 on the electronic book display device 10, each content described above can be realized.
