Therefore, the DB processing unit 155 registers information indicating that the electronic book is an electronic book in the “position” column of the general database.

<Display virtual bookshelf>
FIG. 7 is a diagram illustrating a display example of a virtual bookshelf in the electronic book device 100.

  The virtual bookshelf 500 includes an image (book shelf 590) showing a book shelf frame and images (books 501 to 505) showing books. Each image indicating a book includes the title of the book (name of the book). Each book indicated by books 501 to 505 corresponds to each book whose information is managed in the general database (see FIG. 6).

  That is, the comprehensive database shows information on five books whose titles are “Novel 1”, “Novel 2”, “Novel 3”, “Manga 1”, and “Manga 2”. Among these, “Novel 1”, “Novel 3”, and “Manga 1” are real books whose information is stored in the real book DB 157. “Novel 2”, “Novel 3”, and “Manga 2” are electronic books whose information is stored in the electronic book DB 158. That is, for “Novel 3”, information is managed in the general database for both real books and electronic books. This means that the user of the electronic book apparatus 100 owns the “novel 3” as both a real book and an electronic book.

  Now, with reference to FIG. 7, in the virtual bookshelf 500, images of five books, books 501 to 505, are shown in the upper part of the bookshelf 590. Books 501, 502, 503, 504, and 505 correspond to “Novel 1”, “Novel 2”, “Novel 3”, “Manga 1”, and “Manga 2” on the general database, respectively.

  The book 501 and the book 502 are displayed in different modes (for example, different colors). In FIG. 7, this corresponds to the case where the book 502 is described without being hatched while the book 501 is described without being hatched. The display mode of the books 501 and 504 is a display mode that represents a real book, and the display mode of the books 502 and 504 is a display mode that represents an electronic book.

  Further, the book 503 is shown in a manner different from any of the books 501 and 505 and the books 502 and 504. In FIG. 7, this corresponds to the book 503 being partially hatched and partially hatched. This is because the book 503 stores both information as a real book and information as an electronic book in the general database. Note that the book 503 is displayed in such a manner, so that the book 503 is displayed in a manner intermediate between the display manners of the books 501 and 505 and the books 502 and 504.

  FIG. 8 is a diagram for explaining a specific display example of the virtual bookshelf 500 in the electronic book apparatus 100.

  As shown in FIG. 8, the virtual bookshelf 500 is displayed on the touch panel 134, and a cursor 550 for selecting a book displayed in the virtual bookshelf 500 is displayed on the touch panel 134.

In the pop-up 551 in FIG. 8, information about the book 505 is displayed.
The information displayed in the pop-up 551 is information stored in the general database for the book 505. Specifically, the “type” of the book (“electronic book apparatus A” in FIG. 8) and the book 505 The purchase date and the purchase destination of the book ("Other" in FIG. 8) are included in the example.In the example shown in FIG. 8, the purchase destination of the book is included in the electronic book database.

  FIG. 9 is a diagram illustrating another specific display example of the virtual bookshelf 500 in the electronic book apparatus 100.

  Referring to FIG. 9, in FIG. 9, the cursor 550 is positioned on a book 504 indicating a real book. In FIG. 9, a pop-up 552 indicating information on a real book corresponding to the book 504 is displayed, and a bookshelf image 600 is displayed.

  The bookshelf image 600 is a bookshelf image specified by “type” on the real book database for the book 504. The pop-up 552 indicates the position of the real book corresponding to the book 504 represented by “position” on the real book database. Note that the pop-up 552 indicates the approximate position (upper left, upper right, lower left, lower right, etc.) on the bookshelf image at which the coordinate is located, instead of the “position” coordinate itself on the real book database.

  The bookshelf image 600 is displayed with a graphic 601 for pointing to the real book.

  FIG. 10 is a diagram illustrating still another specific display example of the virtual bookshelf 500 in the electronic book apparatus 100.

  As will be described later, the electronic book device 100 stores, in a general database (see FIG. 6), a book whose information is not registered in either the real book database (see FIG. 4) or the electronic book database (see FIG. 5). Information can be added as a virtual book. In the electronic book device 100, when the cursor is positioned on the image corresponding to the virtual book, information on the virtual book is displayed.

  In the virtual bookshelf 500 of FIG. 10, books 511 to 514 are added to the virtual bookshelf 500 described with reference to FIGS. 7 to 9. Among these, the books 511, 512, and 514 correspond to information added as real books to the example shown in FIG. 7 and the like, but the book 513 corresponds to the virtual book as described above. .

  In FIG. 10, the cursor 550 is located on the book 513. Thereby, in FIG. 10, a pop-up 553 indicating the information of the book 513 is displayed.

  A virtual book is, for example, a book in which information indicating that it has been ordered in the general database and is waiting for arrival is registered. In the pop-up 553 in FIG. 10, a character string indicating the scheduled shipping date of the book 513 is displayed.

  In the present embodiment, an image indicating that there is a “remaining book” that does not include book information in the general database among books published in series by the virtual book image (book 513). Is configured.

A method for generating information on the virtual book will be described later.
<Virtual bookshelf browsing process>
FIGS. 11 and 12 are flowcharts of processing executed when displaying a virtual bookshelf in the electronic book apparatus 100. This process is started, for example, at a timing when an operation for starting an application for browsing an electronic book is performed in the electronic book device 100.

  Referring to FIG. 11, in the virtual bookshelf browsing process, CPU 130 first displays the virtual bookshelf on touch panel 134 based on the general database as described with reference to FIG. The process proceeds to S20.

  Note that the display order of the images of the books stored in the general database on the virtual bookshelf can be any order. For example, by default, the titles of books are in alphabetical order, and the information (additional information) of each book stored in the general database, such as the order of the alphabetical order of the author, is given by the user's instruction. It may be changed on the basis. Furthermore, it may be changed based on the title and the additional information. In particular, for a real book, information for specifying a position in an image is registered. Therefore, in the electronic book device 100, images corresponding to the respective real books can be arranged in accordance with the positions in the actual bookshelf.

  In step S20, the CPU 130 determines whether or not a condition for proposing the update of the general database (see FIG. 6) is satisfied. If it is determined that the condition is satisfied, the process proceeds to step S30, and the condition is determined. If it is determined that it is not established, the process proceeds to step S50.

  Here, as a condition for proposing the update in step S20, for example, a predetermined period (for example, one month) has elapsed since the last update of the general database.

  In addition, as another example of the above conditions, in the general database, when two or more books in a certain series are included, one or more books constituting the series are missing, It is mentioned that a new issue of the series was detected. More specifically, when the information on the books of Volume 1, Volume 2 and Volume 4 of a certain series is registered in the general database, CPU 130 determines that Volume 3 of the series is missing. Then, it is determined that the above condition is satisfied. Note that the CPU 130 can obtain information on letters constituting the series and information indicating that a new publication has been issued in each series, for example, from the homepage of a book sales store on the network.

  In step S30, CPU130 performs the process for proposing the update of a comprehensive database with respect to the user of the electronic book apparatus 100, and advances a process to step S40. As the processing here, for example, as shown in FIG. 13, a message such as “One month has passed since the last update. Do you want to update the general database?” Is displayed.

  Returning to FIG. 11, in step S40, the CPU 130 determines whether or not a request for updating the general database has been received. If it is determined that such a request has been received, the process proceeds to step S130 (see FIG. 12). If it is determined that such a request has not been received, the process proceeds to step S50.

  In FIG. 13, the character strings “YES” and “NO” are displayed on the touch panel 134. In step S40, for example, when a touch operation is performed on the character string “YES”, CPU 130 determines that update of the general database has been requested, and advances the process to step S130. On the other hand, when the character string “NO” is operated, it is determined that there is no update request, and the process proceeds to step S50.

  In step S50, as described with reference to FIG. 8, CPU 130 determines whether or not the position of the cursor displayed on touch panel 134 is positioned on the image representing the electronic book. If it is determined, the process proceeds to step S60, and if not, the process proceeds to step S70.

  In step S60, as described with reference to FIG. 8, the CPU 130 causes the information on the electronic book corresponding to the image on which the cursor is located to be displayed on the touch panel 134 as in the pop-up 551, and in step S70. Proceed to the process.

  Note that the information on the electronic book displayed in step S60 is that the cursor is no longer positioned on the image corresponding to the electronic book on the touch panel 134, or the cursor is positioned on the image. Is erased in accordance with a predetermined period (for example, 10 seconds).

  In step S70, the CPU 130 determines whether or not an operation for selecting an electronic book in the virtual bookshelf displayed on the touch panel 134 has been performed. If it is determined that such an operation has been performed, the process proceeds to step S80. If it is determined that it is not, the process proceeds to step S90 (see FIG. 12).

  In step S80, CPU 130 executes processing for browsing the electronic book determined to have been selected in step S70. Note that the processing for browsing the electronic book in step S80 can be the same as that performed in a known electronic book device, and therefore, redundant description will not be given here.

  In the present embodiment, as described with reference to FIG. 8 and the like, when the cursor is positioned on the book image, a popup including information corresponding to the book is displayed. (For example, when a software key displayed on the operation button 135A or the touch panel 134 is operated, the book is selected, and processing for browsing (for example, display of the contents of the book) is executed. .

  Referring to FIG. 12, in step S <b> 90, CPU 130 determines whether or not the position of the cursor is located on the image corresponding to the real book in the virtual bookshelf on touch panel 134 and determines that it is. The process proceeds to step S100, and if not, the process proceeds to step S110.

  In step S100, CPU130 displays the information about the real book in a virtual bookshelf, as demonstrated with reference to FIG. 9, and advances a process to step S110.

  As the real book information displayed in step S100, as described with reference to FIG. 9, the book shelf image including the real book image and the position of the real book image in the book shelf image are shown. Including pop-ups.

  Note that the information on the real book displayed in step S100 is determined on the condition that the cursor is no longer positioned on the image corresponding to the real book on the touch panel 134, or for a predetermined time after the display is started in step S100 ( For example, it is erased from the touch panel 134 on the condition that 10 seconds have elapsed.

  In the present embodiment, for example, when the cursor is positioned at the position where the image of each book is displayed on the virtual bookshelf, the CPU 130 extracts information on the book corresponding to the image from the general database. If the coordinates are registered in the "" column, it is determined that the cursor is positioned on the real book image, and if "Electronic book" is registered in the "Position" field, the cursor is positioned on the electronic book image. It is judged that it is located in.

  In step S110, the CPU 130 determines whether or not the content of the electronic book database (see FIG. 5) has been updated. If it is determined that the content has been updated, the process proceeds to step S130. Proceed to the process. For example, when an electronic book is purchased in the electronic book device 100, the electronic book device 100 receives an electronic book from another device, or an operation of deleting the electronic book from the electronic book library of the electronic book device 100 is performed. The electronic book database is updated, and the process proceeds from step S110 to step S130.

  In step S120, CPU 130 determines whether or not there has been a request for updating the general database. If it is determined that there is such a request, the process proceeds to step S130, and if it is determined that there is no such request, the process proceeds to step S140. To proceed.

  Here, in step S120, the CPU 130 realizes the determination in step S120 depending on, for example, whether or not an operation for such a request has been performed on the input device 135.

  In step S130, the CPU 130 creates a comprehensive database, registers information constituting the created comprehensive database in the comprehensive database 159, and returns the process to step S50. In step S130, the CPU 130 may delete the information previously registered in the general database 159, or in a mode that can be distinguished from the newly created general database, together with the new general database, Information may be left at 159.

  In step S140, the CPU 130 determines whether or not an operation for ending the browsing of the virtual bookshelf has been performed. If it is determined that such an operation has been performed, the CPU 130 ends the virtual bookshelf browsing process, and such an operation has been performed. If not, the process returns to step S50 (see FIG. 11).

<Display virtual books>
When generating the comprehensive database, the CPU 130 can generate information on the virtual book as described above, and store the information on the virtual book in addition to the information on the electronic book and the real book. Generation of virtual book information will be described.

FIG. 14 is a diagram schematically illustrating another example of information constituting the general database.
In the general database shown in FIG. 14, the titles are “Novel 1” “Novel 2” “Novel 3” “Manga 1” “Manga 2” “Magazine 1” “Magazine 2” “Magazine 4”. The book information is shown. Here, “novel”, “cartoon”, and “magazine” are specific examples of portions constituting the title of a book.

  Of the titles in FIG. 14, “Magazine 1”, “Magazine 2”, and “Magazine 4” are combined with a common title “Magazine” and numbers representing the number of volumes “1”, “2”, and “4”, respectively. It has been done. In this case, the CPU 130 searches the title part on the homepage of the book sales company on the Internet, and obtains the number of published or scheduled publication volumes for the title part. Then, out of the number of turns of the issued or scheduled book, the number of turns not included in the information in the general database is derived as the missing number of turns.

  For example, when the first to fourth volumes have been issued for the “magazine”, that is, when “magazine 1”, “magazine 2”, “magazine 3”, and “magazine 4” have been issued, the CPU 130 "3" (that is, "Magazine 3") is derived as the number of missing volumes.

  Then, the CPU 130 adds the information on the number of missing turns derived in this way to the general database as shown in FIG. FIG. 15 is a diagram schematically showing still another example of information constituting the general database.

  In FIG. 15, information about “Magazine 3” is added as compared to FIG. 14. In FIG. 15, “−” indicating a virtual book is registered as “position” of “magazine 3”.

  The virtual book added in this way is displayed in a different manner from the electronic book and the real book as shown as the book 513 in FIG. 10 on the virtual bookshelf.

<Modification 4>
FIG. 19 is a diagram illustrating a modification of the functional configuration of the electronic book device 100 illustrated in FIG. 3.

  Referring to FIG. 19, the present modification further includes a bookshelf DB 161. The bookshelf DB 161 is realized mainly by the storage device 136, for example.

  The bookshelf DB 161 stores a database (bookshelf database) that stores information associating bookshelf images with information that identifies actual bookshelves. The DB processing unit 155 generates a bookshelf database based on the bookshelf image acquired by the image acquisition unit 153 and information input from the outside. The DB processing unit 155 acquires position information and orientation information of the electronic book device 100 when the bookshelf image is taken by the camera 131, and the position information is registered in the bookshelf DB 161 in advance based on these information. The bookshelf that is the subject of shooting may be identified from the bookshelf, and the photographed bookshelf image may be associated with the identified bookshelf and registered in the bookshelf DB 161.

FIG. 20 is a diagram schematically illustrating an example of information constituting the bookshelf database.
Referring to FIG. 20, in the bookshelf database, a bookshelf name, an image file name, a file storage location, a map file name, and a map storage location are associated with each other.

  The bookshelf name is a name set for each bookshelf (or a part of the bookshelf (the part when one bookcase is divided and photographed)), and is input by the user, for example.

The image file name is a file name of image data of each bookshelf image.
The file storage location is a storage location in the storage device 136 of image data of each bookshelf image.

  The map file name is a file name of an image representing an actual location (a position in a building or the like) for each bookshelf (or a part of the bookshelf).

  The map storage location is a storage location in the storage device 136 or the like of the image data having the map file name.

  In this modified example, as shown in FIG. 21, when a real book on a virtual bookshelf is instructed with a cursor 550, a bookshelf image including the book is displayed on the touch panel 134 as information on the book. The position information of the bookshelf included in the bookshelf image is displayed.

  Referring to FIG. 21, map image 700 is displayed on touch panel 134 in addition to virtual bookshelf 500 and bookshelf image 600.

In the present modification, the CPU 130 can register information on lending for each book in the general database. As information on lending, for example, as shown in FIG. 23, “lending destination” and “lending period” can be mentioned. In the example of FIG. 23, “Manga 1” is registered with “B” (information identifying the borrower, such as a person) as “loan”, and the same year from September 1, 2011 as “loan period”. The period for September 30 is registered.

FIG. 24 is a diagram schematically showing an example of the contents constituting the contact database.
The contact database is information that constitutes a so-called address book. For each contact (person, company, etc.), the “name”, “furigana”, “phone number”, “e-mail address”, “address”, and “schedule” are stored. It is related. Each information is registered in the electronic book apparatus 100 via the input device 135, for example.

FIG. 25 is a diagram for explaining a display example of a virtual bookshelf in the present modification.
Referring to FIG. 25, on the touch panel 134 of the electronic book device 100 of the present modification, some of the books in the virtual bookshelf 500 (books 504 and 514) are overlapped with the title of the book, and “lending” The text “medium” is displayed. Note that the book displayed with the character string “lending” is a book in which information indicating that it is lent is registered in the general DB (see FIG. 23). In the example shown in FIG. 23, information indicating that the loan is being made is configured by “loan” or “loan period”. However, the present invention is not limited to this, and the loan destination and its period are specified. Alternatively, at least information indicating that the loan is in progress may be registered.

  Information such as a lending destination in the general DB is registered in the electronic book device 100 by being input via the input device 135, for example.

  In addition, when the book that is being lent is an electronic book, and the right to browse the electronic book is lent to another user, the electronic book device 100 temporarily has the right to view the electronic book. It is also assumed that it will disappear. In such a case, as shown in FIG. 26, in addition to the book image (book 590), in addition to being lent out, there is an image 590A indicating that browsing of the electronic book is temporarily restricted. It may be displayed.

  Now, in this modification, when a book indicated to be lent out on the virtual bookshelf is pointed by the cursor, as shown in FIG. Is displayed.

  In addition, in such a pop-up 556, it is preferable to display information registered in association with the lending in the general DB, such as the lending period, in addition to the lending destination.

  Note that the CPU 130 specifies a book corresponding to the position of the cursor 550, and if there is a lending destination associated with the book in the general DB, displays the information as a pop-up 556.

  Further, when a book that is being lent is instructed with the cursor 550, in addition to the information shown in FIG. 25, information for contacting the borrower is displayed as shown in FIG. Also good. In the pop-up 557 of FIG. 27, in addition to the “loaner” and “loan period”, the text “YES” and “NO” is displayed together with the message “Do you want to contact Mr. B?” Yes. When “YES” is selected here by a touch operation or the like, CPU 130 causes touch panel 134 to display a menu for contacting the lending destination as shown in FIG.

FIG. 28 shows a screen 710 including the menu as described above.
On the screen 710, the title of the target book (“Magazine 4”) is shown as the title along with the publisher name (“XX Company”). And the information for communicating with the contact of the lending destination (user named “B”) registered in the address book (see FIG. 24) is displayed.

  In the address book of FIG. 24, destinations (telephone numbers and e-mail addresses) for a plurality of communication means are registered for the user. Therefore, the CPU 130 shows a method for communicating for each destination. Specifically, the CPU 130 shows two menus “call” and “send e-mail” on the screen 710. And if operation which selects either of these is made, CPU130 will perform the communication process according to the said selection.

  Specifically, when “call” is selected, a call is made using the telephone number of the user registered in the address book. If “send e-mail” is selected, an e-mail is sent with the mail address of the user registered in the address book as the destination. In this case, the subject and text of the e-mail may be predetermined such as a message for requesting the return of the book. Note that the subject and text of the e-mail may be edited based on information input via the input device 135.

  The menu display as described with reference to FIGS. 27 and 28 constitutes an example of information display for accepting an instruction to communicate with a borrower about a book that is being lent. Such information display may be performed on condition that the lending period has elapsed.

<Modification 6>
