The display unit 40 displays the map information and the current position information of the user on the display screen of the display device, and also displays a guidance route to the destination on the display screen, thereby giving directions to the user. Inform. The display unit 40 displays an electronic book in accordance with a user operation.

  The sensor unit 50 has a function of measuring the current position of the navigation device 100 (that is, the current position of the user). For example, the sensor unit 50 receives a GPS signal transmitted from a GPS satellite, and positions based on the GPS signal. A GPS sensor that measures the amount of movement, a speed sensor that measures the amount of movement (distance) from the initial position, a gyro sensor that measures the traveling (movement) direction, and the like.

  A GPS sensor is a so-called GPS receiver, receives a GPS signal radiated from a GPS satellite, measures a distance (pseudo distance) between the GPS satellite and the GPS receiver itself, and receives a plurality of satellites. Are simultaneously received to calculate the current position (GPS positioning solution) of the GPS receiver itself.

  In addition to the GPS receiver (antenna) that receives the GPS signal, the sensor unit 50 has a function of performing processing such as decoding of the received GPS signal and notifying the control unit 10.

Here, in this example, the “edge” means a front edge that is a portion on the opposite side of the back (back cover) of the book. The small image display unit 13 determines the width of the fore edge image to be displayed according to the number of pages of the electronic book to be displayed. In this example, the fore edge image display unit 13 prepares an image of the fore edge corresponding to the display size of the electronic book on the display screen of the display device in advance (that is, stores it in the storage unit 20). The reference size of the fore edge image corresponding to the electronic book to be displayed is specified, and the value divided by the total number of pages of the electronic book displaying the image width W pixels is defined as the number of pixels of one page. That is, for example, when an e-book having a 100-page configuration is displayed when the width of the fore edge image is 100 pixels, one page corresponds to one pixel. Note that the fore edge display unit 13 displays the image at a predetermined speed while the fore edge image is in a pressed state, for example, since the page is changed by touching the fore edge (that is, the page change is executed by accepting an operation on the fore edge image). The page to be changed may be changed. By adopting such a configuration, it is possible to display a page that cannot be expressed in the fore edge (for example, each page when an e-book having a 200-page structure is displayed when the maximum width of the fore edge image is 100 pixels). Become.

  The fore edge operation accepting unit 14 has a function of executing processing for accepting a predetermined operation for the fore edge image displayed by the fore edge image display unit 13 based on the electronic book information. Here, the “predetermined operation on the fore edge image” includes both “an operation for pressing the display position of the fore edge image” and “an operation on the display mode of the fore edge image”. In this example, as operations for the fore edge image, the control unit 10 executes a plurality of operations (for example, an operation for moving the pressed position of the front screen including the fore edge image display area (so-called slide operation)) and each operation. It is assumed that the processing content to be performed (for example, a page change according to a slide amount (moving distance of the pressed position) in the slide operation) is stored in the storage unit 20 in advance. The fore edge operation reception unit 14 determines which operation has been received based on, for example, the display state of the display screen (for example, what screen is displayed), the pressed position of the display screen, and the like, and the determination result Is notified to the control unit 10.

  The changed page information specifying unit 15 performs a process of specifying changed page information for changing a page currently displayed on the display screen to another page based on a predetermined operation received by the fore edge operation receiving unit 14. Have In this example, the changed page information specifying unit 15 uses, as changed page information, “pages N pages after (or before) the current displayed page (N is a positive integer)” or “N pages”. The information that can specify the page to be displayed is specified according to the received operation.

  In response to the change page information specified by the change page specifying unit 15, the page change effect execution unit 16 changes the page as if the page of the electronic book displayed on the display screen was turned and changed. It has a function of executing a page change effect for displaying the progress. In this example, page change production execution part 16 performs page change production based on change page information which shows a page after change. In this example, the technical contents related to the method for changing a page using a fore edge image will be described in detail, and a method for expressing a state in which a page is turned, that is, a page is actually changed by a page change effect. As described above, since a known technique is used for the method of displaying the page change process on the display screen (for example, animation technique), detailed description thereof is omitted here.

  The page change effect image storage unit 17 is for page change effect displayed at the time of page change effect executed by the page change effect execution unit 16 for each electronic book information stored in the electronic book information storage unit 21 described later. It has a function of executing processing for creating an image and saving it in a page change effect image information storage unit 23 described later. The page change effect image information will be described later again (see FIG. 4). Note that the time for creating the page change effect image by the page change effect image storage unit 17 is not particularly limited, and may be, for example, after the control unit 10 receives an execution request for the page change effect, or a display screen. It may be when a page in which no page change effect image is stored is displayed. Further, it may be immediately after the electronic book information is stored in the electronic book information storage unit 21. In addition, it is good also as a structure which receives the preparation request of the image for page change effects by a user. Further, in this example, the page change effect image is used only in mode 3 described later (see FIG. 10). Moreover, the navigation apparatus 100 is good also as a structure which displays the part of the predetermined range of the page which electronic book information shows instead of the page change effect image storage part 17 as a page change effect image. In this case, it is preferable that the processing load required for the process of displaying only a predetermined range of the page indicated by the electronic book information (for example, a page image of a quarter of the entire page from the right end of the page) is not excessive.

  The posture change detection unit 18 has a function of executing processing for detecting a change in posture of the electronic book apparatus itself. Since posture detection is realized using a known technique using an acceleration sensor, detailed description thereof is omitted here.

  The page display part 19 performs the process for displaying each page which comprises an electronic book on the display screen of the display part 40 based on the electronic book information mentioned later. Further, the page display unit 19 performs processing for displaying an electronic book in a plurality of display modes in page display processing described later.

  The storage unit 20 is a storage medium that includes a ROM, a RAM, and the like, and stores various computer programs used by the navigation device 100. In this example, as shown in FIG. 2, the storage unit 20 includes an electronic book information storage unit 21, a map information storage unit 22, and a page change effect image information storage unit 23.

  The electronic book information storage unit 21 is a storage medium that stores electronic book information including page information for displaying each page constituting the electronic book. The electronic book information storage unit 21 in this example stores a plurality of pieces of electronic book information. Each electronic book information includes the page information, the date and time when each electronic book was stored, the publication date of the book, and the author. Various information about electronic books, such as publishers and publishers. Electronic books include electronic books of various genres such as general travel guidebooks that provide information on specific areas, operation manuals that explain how to operate machinery, etc. And

  The electronic book information is preferably information that can be read (displayed) by more types of electronic book devices. Therefore, in this example, the contents of the electronic book information cannot be corrected.

  FIG. 3 is an explanatory diagram illustrating an example of a storage state of electronic book information in the present example. As shown in FIG. 3, the electronic book information in this example is “1” only for the electronic book ID for uniquely identifying the electronic book, the book name, the number of constituent pages, and the electronic book being displayed on the display screen. And a display flag (number of pages) being displayed on the display screen.

  The map information storage unit 22 is a storage medium that stores map information by dividing it into a predetermined grid (in this example, a rectangular range divided by a constant latitude width and latitude width). In addition to being stored in the map information storage unit 22, the map information can be stored in an auxiliary storage device as a removable medium called an SD memory card, a CD-ROM, a DVD-ROM, or the like. Further, the map information may be downloaded via a communication network such as the Internet.

  The page change effect image information storage unit 23 is a storage medium serving as a storage destination of the page change effect image information created by the page change effect image storage unit 17.

  FIG. 4 is an explanatory diagram showing an example of a storage state of page change effect image information in the page change effect image information storage unit 23. As shown in FIG. 4, the page change effect image information includes an electronic book ID and a page change effect image specifying method.

  Here, the “page change effect image specifying method” indicates a method of specifying an image used as a page change effect image. Examples of the image specifying method for page change effect include “A pixel (A is an arbitrary number) from the right end of the page” or “Y pixel (X, Y) at the right end when the resolution of the page information is X dpi (dot per inch)”. Are both arbitrary numerical values) ”. Note that the page change effect image specifying method may be configured to be settable by the user.

  The page change effect image specifying method may be configured to be set by the control unit 10 (or a person who performs digitization) according to the information amount of the electronic book information when the book is digitized, or a navigation device. It is good also as a structure which can be set by 100 users.

  Next, the operation of the navigation device 100 of this example will be described with reference to the drawings. Note that detailed descriptions of processes not particularly related to the present invention may be omitted.

  FIG. 5 is a flowchart illustrating an example of a page display process executed by the navigation device 100. In the page display process, a process for displaying an arbitrary page of the electronic book on the display screen of the display unit 40 according to the operation of the user A of the navigation device 100 is performed.

  The page display process in this example is started when, for example, selection of an electronic book by the user A is received. At this time, the control unit 10 sets only the display flag corresponding to the electronic book displayed on the display screen to “1” (see FIG. 3).

  In the page display process, first, the control unit 10 displays a normal page display screen on the display screen of the display unit 40 (step S101). Here, “normal” is an expression for various display screens (a mode 1 screen, a mode 2 screen, and a mode 3 screen) to be described later which are special display modes.

  FIG. 6 is an explanatory diagram for explaining a change from the normal page display screen to the mode 1 screen. FIG. 6A is an explanatory diagram illustrating an example of a normal page display screen. As shown in FIG. 6A, the normal page display screen includes a page display area 102 for displaying at least a part of the page of the electronic book, and a plurality of buttons 103A to 103E for receiving an operation input by the user A. And an operation button display area 103. For example, the control unit 10 changes the page displayed on the display screen 101 in response to the page turning button 103A or the button 103B being pressed by the finger F of the user A, for example.

  When the normal page display screen is displayed, the control unit 10 determines whether or not a transition operation to “mode 1” from the user A has been received (step S102). Here, the “mode” indicates the type of method for accepting the operation of the electronic book by the user A. In this example, the control unit 10 selects a plurality of types of modes according to the operation by the user A. Execute. Hereinafter, in this example, “mode 1” for displaying an arbitrary page of the electronic book and a fore edge image, an arbitrary spread of the electronic book (that is, any two consecutive pages of the electronic book), and an fore edge image. The “mode 2” to be displayed and the “mode 3” to display the page change effect image and the fore edge image corresponding to any one page of the electronic book will be described.

  In this example, the control unit 10 performs a slide operation (pressing of the display screen 101 with the finger F of the user A) on the screen edge (for example, the fore edge image display scheduled portion 102A (see FIG. 6A)) on the display screen 101. (Position movement operation) is accepted as a transition operation to mode 1.

  When the transition operation to the mode 1 is not accepted (N in Step S102), the control unit 10 proceeds to the process of Step S201 described later.

  On the other hand, if it is determined that the transition operation to the mode 1 is accepted (Y in step S102), the control unit 10 causes the page display unit 19 to display the mode 1 screen on the display screen 101 as shown in FIG. 6B, for example. It is displayed (step S103).

  The mode 1 screen in this example includes a page image display area 104 and a fore edge image display area 105 as shown in FIG. When displaying the mode 1 screen, the control unit 10 causes the forehead face image display unit 13 to display the page displayed in the page image display area 104 (in this example, the page display area 102 in the normal page display screen). The fore edge image corresponding to the page that was being displayed is displayed. Specifically, the control unit 10 uses the fore edge image display unit 13 to specify the vertical and horizontal size of the fore edge image from the vertical size and the number of pages of the page displayed in the page image display area 104, and Displayed in the image display area 105. Note that the fore edge image display unit 13 is preferably configured to display the fore edge pattern 106 corresponding to the electronic book being displayed. In this case, for example, fore edge pattern data is stored as electronic book information, and when the fore edge image is displayed, the fore edge image display unit 13 refers to the electronic book information storage unit 21 and the display flag is set to “1”. If the configuration is such that the fore edge pattern data corresponding to the read electronic book is read and the fore edge image including the fore edge pattern 106 is displayed in the fore edge image display area 105 with a width corresponding to the number of pages displayed in the page image display area 104. Good (see FIGS. 3 and 6B).

  When the mode 1 screen is displayed, the control unit 10 receives a predetermined operation (fore edge operation) for the fore edge image display area 105 through the fore edge operation reception unit 14 (step S104). Here, when not accepting the fore edge operation (N in Step S104), the control unit 10 proceeds to the process of Step S108 described later.

  On the other hand, when it is determined that the fore edge operation has been received (Y in step S104), the control unit 10 specifies changed page information corresponding to the received fore edge operation by the changed page information specifying unit 15 (step S105).

  FIG. 7 is an explanatory diagram for explaining the fore edge operation on the mode 1 screen. For example, as illustrated in FIG. 7A, when a slide operation in the right direction with respect to the operation area 107 including the display position of the fore edge image display area 105 is received, the control unit 10 changes the change page information specifying unit 15 to The change page information for specifying a later page is specified.

  When the changed page information is specified, the control unit 10 causes the page change effect executing unit 16 to execute the page change effect based on the specified changed page information (step S106). In this example, it is assumed that the page change effect execution unit 16 reproduces an animation that artificially (or virtually) shows how pages are turned by the number of pages indicated by the changed page information.

  When the page change effect is executed, the control unit 10 displays a mode 1 screen for displaying the changed page (step S107). In this example, it is assumed that the control unit 10 performs the page change effect execution unit 16 until the page after the change is displayed. For example, as shown in FIG. 7B, the control unit 10 displays the changed page 104A and the fore edge image having a width corresponding to the changed page 104A on the mode 1 screen for displaying the changed page. 105A is displayed.

  When the changed page is displayed, the control unit 10 determines whether or not to end the mode 1 screen by accepting a predetermined operation (for example, pressing of the button 103D) (step S108). If it is determined that the mode 1 screen is not terminated (N in step S108), the control unit 10 proceeds to the process in step S104.

  On the other hand, if it is determined that the mode 1 screen is to be ended by accepting a predetermined operation (Y in step S108), the control unit 10 proceeds to the process in step S101.

  6 and 7, the fore edge image display area 105 is arranged on the right side of the page image display area 104, and the page is displayed when a rightward slide operation for the fore edge image (that is, the fore edge image display area 104) is received. The configuration for advancing is described. However, the display mode of the mode 1 screen is not limited to this. For example, when a predetermined operation (for example, a leftward sliding operation with respect to the page image display area 104) is received, the control unit 10 displays the fore edge image display area. May be arranged on the left side of the page image display area 104, and the page may be returned when a slide operation to the left with respect to the fore edge image is received (that is, a page closer to the cover than the currently displayed page is displayed). .

  On the other hand, in the process of step S102 in the above-described page display process, when it is determined that the transition operation to the mode 1 is not accepted (N in step S102), the control unit 10 performs the transition operation to the “mode 2” from the user A. Is determined (step S201).

  FIG. 8 is an explanatory diagram for explaining the change from the normal page display screen to the mode 2 screen. FIG. 8A is an explanatory diagram illustrating an example of the transition operation to the mode 2 on the normal page display screen. As shown in FIG. 8A, on the normal page display screen, the control unit 10 accepts a so-called pinch-in operation on the page display area 102 as a transition operation to the mode 2 with the finger F of the user A. The “pinch-in operation” is an operation of placing two fingers on the screen to reduce the interval between them, and is often used for, for example, screen reduction in an apparatus equipped with a multi-touch panel. In the case where the navigation device 100 does not support multi-touch, another operation method may be set as a transition operation to the mode 2.

  When a transition operation to mode 1 is not accepted (N in step S201), the control unit 10 proceeds to a process in step S301 described later.

  On the other hand, if it is determined that a transition operation to mode 2 has been accepted (Y in step S201), the control unit 10 causes the page display unit 19 to display a mode 2 screen on the display screen 101 as shown in FIG. 8B, for example. It is displayed (step S202).

  In this example, as shown in FIG. 8B, the control unit 10 displays a plurality of pages 201 and 202 constituting the electronic book B in a spread form as a mode 2 screen, and a fore edge image corresponding to each page. 210A and 202A are displayed.

  When the mode 2 screen is displayed, the control unit 10 causes the fore edge operation accepting unit 14 to accept a predetermined operation (fore edge operation) on the fore edge image 201A or the fore edge image 202A (step S203). Here, when not accepting the fore edge operation (N in Step S203), the control unit 10 proceeds to the process of Step S207 described later.

  On the other hand, if it is determined that the fore edge operation has been received (Y in step S203), the control unit 10 specifies changed page information corresponding to the received fore edge operation by the changed page information specifying unit 15 (step S204).

  FIG. 9 is an explanatory diagram for explaining the fore edge operation on the mode 2 screen. For example, as illustrated in FIG. 9A, when a leftward sliding operation is performed on the operation area 203 including the display positions of the fore edge image 201A and the fore edge image 202A, the control unit 10 causes the change page information specifying unit 15 to The changed page information for specifying the changed page is specified. That is, for example, when the user A's finger F accepts the pressing of the point D within the display position of the fore edge image 202A and determines that the pressing position has moved leftward on the screen, the control unit 10 changes the changed page information specifying unit 15. Thus, based on the position of the point D with respect to the fore edge image 202A, the moving speed of the pressed position, the moving distance of the pressed position, etc., a change for specifying the changed page (or the changed page and the page change speed) Specify page information.

  When the changed page information is specified, the control unit 10 causes the page change effect executing unit 16 to execute the page change effect based on the specified changed page information (step S205).

  In this example, the page change effect execution unit 16 displays the progress of the page change so that the page of the electronic book displayed on the display screen 101 is turned and the page is changed. Specifically, for example, as shown in FIG. 9B, an animation is reproduced in which the page P is turned up by the number of pages indicated by the changed page information in a pseudo (or virtual) manner.

  When the page change effect is executed, the control unit 10 displays a mode 2 screen for displaying the changed page (step S206). In this example, it is assumed that the control unit 10 performs the page change effect execution unit 16 until the page after the change is displayed. In the mode 2 screen for displaying the changed page, for example, as shown in FIG. 9C, the control unit 10 corresponds to the changed pages 204 and 205 and the changed pages 204 and 205. The narrow edge images 204A and 205A are displayed.

  When the changed page is displayed, the control unit 10 determines whether or not to end the mode 2 screen by accepting a predetermined operation (for example, pressing the button 103D) (step S207). If it is determined that the mode 2 screen is not terminated (N in step S207), the control unit 10 proceeds to the process in step S203.

  On the other hand, if it is determined that the mode 2 screen is to be ended by accepting a predetermined operation (Y in step S207), the control unit 10 proceeds to the process in step S101.

  On the other hand, in the process of step S201 in the page display process described above, when it is determined that the transition operation to mode 2 is not accepted (N in step S201), the control unit 10 performs the transition operation from user A to “mode 3”. Is determined (step S301). In this example, the control unit 10 performs a double-click operation (for example, with the finger F of the user A) on the screen edge (for example, the fore edge image display scheduled portion 102A (see FIG. 6A)) on the display screen 101. Are assumed to be accepted as a transition operation to the mode 3 (an operation of pressing twice an area (including the same position) within a predetermined time).

  When the transition operation to the mode 3 is not accepted (N in step S301), the control unit 10 proceeds to a process in step S401 described later.

  On the other hand, when determining that the transition operation to the mode 3 is accepted (Y in step S301), the control unit 10 causes the page display unit 19 to display the mode 3 screen on the display screen 101 (step S302).

  FIG. 10 is an explanatory diagram for explaining the mode 3 screen. As shown in FIG. 10, the mode 3 screen in this example is a page change corresponding to the page displayed in the page display area 102 (see FIG. 6A) on the normal page display screen before the transition to mode 3. A page change effect image display area 301 for displaying the effect image (see FIG. 4) and a fore edge image corresponding to the page corresponding to the page change effect image displayed in the page change effect image display area are displayed. A fore edge image display area 302. Therefore, when the control unit 10 deletes the normal page display screen and displays the mode 3 screen, the control unit 10 refers to the page change effect image information storage unit 23 and corresponds to the page displayed in the page display area 102. Search for a change effect image.

  When the mode 3 screen is displayed, the control unit 10 causes the fore edge operation accepting unit 14 to accept a predetermined operation (fore edge operation) for the fore edge image display area 302 (that is, for the fore edge image displayed in the fore edge image display area 302). (Step S303). If the fore edge operation is not accepted (N in step S303), the control unit 10 proceeds to the process in step S308 described later.

  On the other hand, if it is determined that a fore edge operation (for example, a slide operation with the finger A of the user A with respect to the fore edge image display area 302) has been received (Y in step S303), the control unit 10 uses the changed page information specifying unit 15 to accept the fore edge The changed page information corresponding to the operation is specified (step S304).

  When the changed page information corresponding to the accepted fore edge operation is specified, the control unit 10 refers to the page change effect image information storage unit 23 and selects the page change effect image corresponding to the changed page information (step S305). . In this example, for example, when the changed page information indicates “page after change = page advanced by 10 pages from the currently displayed page”, the control unit 10 is stored in the page change effect image information storage unit 23. A page change effect image from the page currently displayed on the display screen 101 to the changed page is selected from the page change effect image information.

  When the page change effect image is selected, the control unit 10 causes the page change effect execution unit 16 to execute the page change effect based on the specified change page information and the selected page change effect image (step S306).

  In this example, the page change effect execution unit 16 displays the progress of the page change so that the page of the electronic book displayed on the display screen 101 is turned and the page is changed. Specifically, the control unit 10 changes the page change effect image displayed in the page change effect image display area 301 to one corresponding to a page closer to the page after the change at predetermined time intervals. In addition, the width of the fore edge image displayed in the fore edge image display area 302 is changed to a width corresponding to the page corresponding to the page change effect image displayed in the page change effect image display area 301. The “predetermined time interval” is preferably a speed (time interval) at which the user A can confirm the change in the width of the fore edge and the page change effect image to some extent.

  When the page change effect is executed, the control unit 10 displays a mode 3 screen for displaying the changed page (step S307). In this example, it is assumed that the control unit 10 performs the page change effect execution unit 16 until the page after the change is displayed.

  When the changed page is displayed, the control unit 10 determines whether or not to end the mode 3 screen by accepting a predetermined operation (for example, pressing of the button 103D) (step S308). If it is determined that the mode 3 screen is not terminated (N in step S308), the control unit 10 proceeds to the process in step S303.

  On the other hand, if it determines with complete | finishing a mode 3 screen (Y of step S308), the control part 10 will transfer to the process of step S101.

  On the other hand, in the process of step S301 in the above-described page display process, when determining that the transition operation to mode 3 is not accepted (N in step S301), the control unit 10 performs an end operation of the normal page display screen from the user A. It is determined whether it has been accepted (step S401). In this example, the control unit 10 accepts pressing of the button 103E on the display screen 101 as an end operation of the normal page display screen.

  When the end operation of the normal page display screen is not accepted (N in step S401), the control unit 10 proceeds to the process of step S101 in the page display process. On the other hand, when an end operation of the normal page display screen is received (Y in step S401), the control unit 10 deletes the normal page display screen from the display screen 101 and ends the processing here.

  As described above, in the above-described embodiment, an electronic book device (for example, an electronic book) that displays the contents of an electronic book that is an electronic book on the display screen 101 of the display device (for example, the display unit 40). A navigation device 100) having a function as a device includes an electronic book information storage unit 21 that stores electronic book information including page information for displaying each page constituting the electronic book, and the electronic book is displayed on the display screen 101. A fore edge image (for example, a fore edge image displayed in the fore edge image display area 105) is received, a predetermined operation (for example, a slide operation) is received for the displayed fore edge image, and the received predetermined operation is received The change page information for changing the page currently displayed on the display screen 101 to another page is identified based on the change page information. A page change effect is displayed to display the progress of the page change (for example, in a pseudo or virtual manner) so that the page of the electronic book displayed on the display screen 101 is turned in response to the change. Since it is configured, it is possible to provide the user with an operational feeling close to the operation of turning a page of a book that exists as a tangible object.

  That is, as a result of the page being turned according to the operation on the fore edge (front edge), the page displayed on the display screen 101 appears to be changed, so that the page of the actual book is flipped by pressing the fore edge of the book. Operability can be realized. In addition, by introducing the concept of “small edge” into the electronic book device, it is possible to visually grasp the position of the page being displayed (the position of the page in the entire book).

  In the page change effect, the control unit 10 may be configured to express at a speed that allows a part of the edge of the forehead page to be confirmed to some extent when the page is turned in a pseudo manner. preferable.

  In the embodiment described above, the page change executed by the electronic book device (for example, the navigation device 100 having a function as the electronic book device) is performed for each electronic book information stored in the electronic book information storage unit 21. A page change effect image displayed at the time of the effect is created and stored in a predetermined storage area (for example, the page change effect image information storage unit 23). Since the page change effect image is displayed as a part of the contents of each page to be displayed (see, for example, FIG. 10), the user can easily find the target page visually.

  In the embodiment described above, the electronic book device (for example, the navigation device 100 having a function as an electronic book device) accepts the slide operation at the pressed position with respect to the fore edge image, and the position and speed of the accepted slide operation. Therefore, it is possible to provide the user with an operational feeling that is closer to the operation of turning the page of a book that exists as a tangible object.

  In the above-described embodiment, the electronic book device (for example, the navigation device 100 having a function as an electronic book device) has a predetermined position for the fore edge image display scheduled portion 102A on the display area of the electronic book on the display screen 101. Since the fore edge image is displayed in response to accepting the operation, the fore edge image can be easily displayed when the user needs the fore edge image.

  In the above-described embodiment, the electronic book device (for example, the navigation device 100 having a function as an electronic book device) displays a fore edge image in response to receiving a pinch-in operation on the display screen 101. Therefore, the fore edge image can be easily displayed when the user needs the fore edge image.

  The operation required for displaying the fore edge image (that is, the transition operation to mode 1, mode 2, and mode 3) is not particularly limited. For example, a dedicated button may be displayed on the display screen 101. Good.

  In the above-described embodiment, the electronic book page (for example, the navigation device 100 having a function as an electronic book device) is displayed on the display screen 101 of the display device (for example, the display unit 40). Since the display mode of the fore edge image is changed according to the number of pages (that is, the width of the fore edge image is changed, for example, when displaying the first half page and the second half page in the electronic book) The user can intuitively understand which side the electronic book has been turned to and which side is being referred to.

  In the above-described embodiment, the case where a slide operation is received as an operation (a forehead operation) on the fore edge image has been described, but the fore edge operation is not limited to this. That is, for example, the electronic book device may accept a long press operation or a tap operation (an operation of tapping the display screen with a fingertip) or the like as the fore edge operation. In this case, for example, the number of pages to be turned and the turning speed may be changed according to the long press time, or the page corresponding to the position where the tap operation is received may be specified and the page may be changed. Moreover, it is good also as a structure which advances one page and the page to display with respect to one tap operation with respect to a fore edge image. In this case, for example, in the mode 2 screen (see FIG. 9C), when a tap operation on the fore edge image 204A displayed on the left side is accepted, the page image 204 on the left side is turned and the fore edge image displayed on the right side is displayed. When a tap operation on 205A is accepted, the right page image 205 may be turned.

  In addition, an electronic book device (for example, the navigation device 100 having a function as an electronic book device) may be configured to change a page using a sensor such as the posture change detection unit 18.

  That is, the electronic book device (for example, the navigation device 100 having a function as an electronic book device) detects a change in posture of the electronic book device itself, and changes the page information as change page information corresponding to the detected degree of posture change. A configuration may be adopted in which the number of changes is determined and the progress of page changes is displayed so that the pages are turned together by changing the determined number of page changes. With such a configuration, the reaction of the electronic book with respect to the inclination can be made closer to the reaction with respect to the inclination of the book existing as a tangible object.

  Further, the electronic book device (for example, the navigation device 100 having a function as an electronic book device) detects the inclination angle of the electronic book device itself with respect to the basic posture, and changes the page per unit time based on the detected inclination angle. It is good also as a structure which determines a number.

  The electronic book displayed on the display screen 101 when the electronic book device (for example, the navigation device 100 having a function as an electronic book device) has a tilt angle of a predetermined angle or more (for example, 91 degrees or more). The change page information indicating that the front cover or the back cover of the electronic book is displayed and the change page information indicating the display of the cover or back cover of the electronic book displayed on the display screen 101 is specified, It is good also as a structure which performs the page change effect which uses the cover or back cover of an electronic book as a page after a change.

  FIG. 11 is an explanatory diagram for describing an example in which a page is changed using a change in posture of the navigation device 100. For example, as shown in FIG. 11A, it is assumed that a navigation device 100 having a function as an electronic book device displays a mode 2 screen in a predetermined basic posture. At this time, when the control unit 10 detects that the navigation device 100 is tilted as shown in FIGS. 11B and 11C by the posture detection unit 18, the change page information specifying unit 15 causes the tilt angle to be changed. (Or, for example, a predetermined element including a speed when tilting) (for example, 0 to 15 degrees = fixed, 16 to 50 degrees = 1 page / second, 51 to 90 degrees = 5 pages / second, 91 The page change effect including the display of the fore edge image PU having a width corresponding to the page change amount is executed by the page change effect execution unit 16.

  Although not particularly mentioned in the above-described embodiment, an electronic book device (for example, the navigation device 100 having a function as an electronic book device) is displayed on the display screen 101 of the display device (for example, the display unit 40). A keyword may be extracted from the displayed page, a destination may be searched using the extracted keyword, and a recommended travel route to the searched destination may be searched.

  INDUSTRIAL APPLICABILITY The present invention is industrially useful in an industry that handles devices that display electronic books, and is also useful in the electrical appliance market such as car navigation devices that can display electronic maps.
