  The information processing apparatus 1 according to the present embodiment can implement various processes as described later with the above-described hardware configuration.

<Functional configuration>
Next, the functional configuration of the information processing apparatus 1 will be described. FIG. 3 is a functional configuration diagram of an example of the information processing apparatus according to the present embodiment. The information processing apparatus 1 includes an input unit 11, an input detection unit 12, a screen generation unit 13, a display control unit 14, and a display unit 15. The information processing apparatus 1 uses the electronic document data 1000.

  The input unit 11 is realized by the CPU 106, the input device 101, and the like, and performs an input operation from the user via the input device 101 (touch panel 10 as a touch sensor) (that is, an input performed by bringing the user's finger or the like into contact with the touch panel 10) Operation). When receiving the input operation, the input unit 11 notifies the input detection unit 12 that the input operation has been received.

  Here, the input operation performed by the user via the touch panel 10 includes a touch operation, a tap operation, a flick operation, and the like. The touch operation is an operation for maintaining the state in which the touch panel 10 is in contact with, for example, a user's finger. The tap operation is an operation of releasing the finger or the like from the touch panel 10 within a predetermined time after the touch panel 10 is brought into contact with the user's finger or the like, for example. Further, the flick operation is an operation of moving the finger or the like in a state where the touch is maintained within a predetermined time after the touch panel 10 is brought into contact with the user's finger or the like.

  Further, the user is not limited to the input operation via the touch panel 10, and can perform the input operation using, for example, a hard key (not shown) provided in the information processing apparatus 1.

  The input detection unit 12 is realized by the CPU 106 or the like, and detects what input operation is the input operation received by the input unit 11. That is, the input detection unit 12 detects which position on the touch panel 10 the user has performed the input operation such as the touch operation, the tap operation, and the flick operation described above.

  Then, the input detection unit 12 makes a predetermined request to the display control unit 14 or the screen generation unit 13 in accordance with the detected input operation. For example, when the flick operation in a predetermined direction is performed on the page search screen displayed on the touch panel 10, the input detection unit 12 displays a request for scrolling the displayed page search screen in the predetermined direction. This is performed for the control unit 14. For example, when the input detection unit 12 performs a tap operation on a position indicating a predetermined page of the electronic document data 1000 on the page search screen displayed on the touch panel 10, the page search screen including the corresponding page. Is generated to the screen generation unit 13. In other words, the input detection unit 12 makes a predetermined request to the screen generation unit 13 in the case of an input operation that requires screen generation in accordance with the detected input operation, but does not require screen generation. In the case of an operation, a predetermined request is made to the display control unit 14.

  The screen generation unit 13 generates a screen to be displayed on the display device 102 based on the electronic document data 1000 in response to a request from the input detection unit 12. For example, the screen generation unit 13 generates a page search screen based on the electronic document data 1000 in response to a request from the input detection unit 12. As will be described later, the page search screen cuts out the contents of a predetermined range (for example, every page) of the electronic document data 1000 by a predetermined range (clipping), and stores information on the cut-out area. It is the screen displayed side by side in multiple horizontal directions.

  For example, the screen generation unit 13 generates a display screen that displays the contents of a predetermined page of the electronic document data 1000 in response to a request from the input detection unit 12.

  The display control unit 14 controls the screen displayed on the display device 102 in response to a request from the input detection unit 12 or the screen generation unit 13. For example, the display control unit 14 performs control to scroll the screen displayed on the display device 102 in response to a request from the input detection unit 12. Further, for example, the display control unit 14 performs control to display the screen generated by the screen generation unit 13 on the display device 102 in response to a request from the screen generation unit 13. The display unit 15 causes the display device 102 to display a screen according to the control of the display control unit 14.

  Subsequently, data used by the information processing apparatus 1 will be described. The electronic document data 1000 is data regarding an electronic document stored in a storage device or the like connected to the SSD 108 or the information processing apparatus 1 via a network.

  The electronic document data 1000 is, for example, an electronic book file or a PDF (Portable Document Format) file. The electronic document data 1000 includes content information and page information. The content information is data such as a document or an image displayed on the display device 102 of the information processing apparatus 1. On the other hand, the page information is associated with the content information and is information related to the page on which the content information is displayed. As described above, the electronic document data 1000 includes the page information and the content information associated with the page information, so that the information processing apparatus 1 can display the content information corresponding to the page information.

<Operation flow>
Next, the flow of operations on the page search screen of the information processing apparatus 1 according to the present embodiment will be described. FIG. 4 is a diagram for explaining an example of the operation of the page search screen.

  First, the user performs a display operation of a page search screen for searching for a desired page of the electronic document data 1000. This can be displayed, for example, when the user selects the electronic document data 1000 via the touch panel 10 of the information processing apparatus 1 and taps a page search button (not shown) or the like. Then, a page search screen 2100 as shown in FIG. 4 is displayed on the touch panel 10 of the information processing apparatus 1 (step S1).

Here, the page search screen 2100 will be described. As described above, the electronic document data 1000 includes page information and content information corresponding to the page information. When the electronic document data 1000 is N-page electronic document data, page information n (n = 1,..., N) indicating the nth page, and content information corresponding to the page information n is content information 1000 _n . To do. Then, the page search screen 2100 displays information on a predetermined area of the content information 1000 _n (here, an area 1100 _{n obtained} by cutting off the right end of the content information 1000 _n ) for each predetermined range (here, for each page). They are displayed side by side in a plurality of left and right directions (here, in ascending order of page information from the right). That is, the page search screen 2100 shown in FIG. 4 displays the area 1100 _n−4 to area 1100 _{n + 7} of content information 1000 _n−4 to content information 1000 _{n + 7 in} the order of page information from the right.

Each of the above-mentioned areas 1100 _n is an area obtained by cutting out a predetermined right end of each piece of content information 1000 _n. Therefore, the page search screen 2100 includes characters, images, etc. displayed in these cut-out areas. Displayed (actual size). Therefore, the user can search for a desired page based on characters, images, and the like displayed in each of the cut out areas 1100 _n−4 to 1100 _{n + 7} . It should be noted that the characters, images, etc. displayed in each area 1100 _n displayed on the page search screen 2100 are not limited to being displayed in their original size, but may be displayed at least without being reduced in the vertical direction. .

Then, when the user performs a tap operation on the area 1100 _n of the page that the user thinks is close to the desired page, the screen transitions to a page search screen 2200 described in the next step S2. When the user finds a desired page on the page search screen 2100, for example, a desired page (content information 1000 _n ) is obtained by performing a touch operation, a double tap operation, or the like on the area 1100 _n of the page. Can be displayed.

In the page search screen 2100 illustrated in FIG. 4, when the user does not have a desired page, the user performs a flick operation on the touch panel 10 in a predetermined direction (for example, left direction or right direction) to thereby display the page search screen. 2100 can be scrolled. Thus, it is possible to change the regions 1100 _n on the page search screen 2100.

Here, the page search screen 2100 shown in FIG. 4, although twelve regions 1100 _n are displayed side by side, not limited to this and may be any number.

Further, the page search screen 2100 may be a screen in which a plurality of pieces of information of the area 1100 _n of the content information 1000 _n are arranged in a horizontal direction for each predetermined range such as every two pages. That is, for example, when the page search screen 2100 is displayed every two pages,..., Region 1100 _n , region 1100 _{n + 2} , region 1100 _{n + 4} ,. In this case, for example, when the user performs a touch operation or a double tap operation on the region 1100 _n , the content information 1000 _n and the content information 1000 _{n + 1} may be displayed (that is, displayed for two pages). .

Each region 1100 _n is a region obtained by cutting out a predetermined right end portion of the content information 1000 _n , but may be a region where a predetermined left end portion is cut out, or may be a region obtained by cutting out a predetermined middle region. . Further, the present invention is not limited to these, and each area 1100 _n may be an area obtained by cutting out an arbitrary predetermined portion in the content information 1000 _n . These are not limited to each area 1100 _n displayed on the page search screen 2100, and the same applies to, for example, a page search screen 2200 and a page search screen 2300 described later.

Next, as described above, the page search screen 2100, when a tap operation on region 1100 _n, page search screen 2200 is displayed (step S2).

Here, the page search screen 2200 will be described. Page search screen 2200 is a screen for the user to retrieve pages near the region 1100 _n selected by a tap operation in more detail in the step S1. That is, the page search screen 2200 displays information on the area 1200 _{n obtained} by cutting off the right end portion of the content information 1000 _n on the page in the vicinity of the area 1100 _n selected by the user by tapping in step S1. They are displayed in ascending order. However, the display area of each area 1200 _n is larger than each area 1100 _n . Therefore, the user can search for a desired page based on the information displayed in each area 1200 _n in which the display area is expanded for the page near the area 1100 _n selected on the page search screen 2100.

When the user performs a tap operation on the area 1200 _n of the page that the user thinks is near the desired page (here, the user performs a tap operation on the area 1200 _n-3 ), The page transitions to a page search screen 2300 described in step S3. Similarly to the above, if the user finds a desired page in the page search window 2200, for example, by performing a touch operation or a double tap operation or the like to the region 1200 _n of the page, the desired page (content Information 1000 _n ) can be displayed.

In the page search screen 2200 shown in FIG. 4, when the user does not have a desired page, the user performs a flick operation on the touch panel 10 in a predetermined direction (for example, left direction or right direction) to thereby display the page search screen. 2200 can be scrolled. Further, the page search window 2200, although six regions 1200 _n are displayed side by side, not limited to this and may be any number less than the number of regions 1100 _n on the page search screen 2100.

Subsequently, as described above, when a tap operation is performed on the area 1200 _n-3 on the page search screen 2200, the page search screen 2300 is displayed (step S3).

Here, the page search screen 2300 will be described. The page search screen 2300 is a screen for searching in more detail a page in the vicinity of the area 1200 _n-3 selected by the user by tapping in step S2. That is, the page search screen 2300 displays an area 1300 _n obtained by cutting the right end portion of the content information 1000 _n in the page in the vicinity of the area 1200 _n-3 selected by the user by tapping in step S2 from the right. They are displayed in ascending order. However, the display area of each area 1300 _n is larger than each area 1200 _n . Therefore, the user selects a desired page based on information displayed in each of the areas 1300 _n-4 to 1300 _n-2 in which the display area is expanded for the page near the area 1200 _n-3 selected on the page search screen 2200. Can be searched.

Then, if the user has found the desired page in the page search screen 2300, for example, the tap operation or the touch operation on the region 1200 _n of the page, double-tapping operation or the like by performing (in FIG. 4 the user area 1300 _n-4 is tapped), and a desired page (content information 1000 _n-4 ) can be displayed.

As described above, the user selects the area 1100 _n or the area 1200 _n on the page search screen 2100 or the page search screen 2200, so that the displayed areas are sequentially expanded for pages near the selected area. Can be searched. In other words, the user selects the area 1100 _n or the area 1200 _n on the page search screen 2100 or the page search screen 2200, thereby reducing (limiting) the search range and expanding the display range of the content information. Search can be performed. In the above description, the page search screen 2100 is displayed and then the search range is narrowed down twice, and then the content information of the desired page is displayed. However, the present invention is not limited to this, and the search range is limited to any number of times. Can be made.

  In the page search screen 2200, the user may be able to transition to the page search screen 2100 by pressing a hard key (not shown) for performing a “return” operation of the information processing apparatus 1, for example. Similarly, on the page search screen 2300, for example, the user may be able to transition to the page search screen 2200 by pressing a hard key (not shown) for performing a “return” operation of the information processing apparatus 1. .

<Details of processing>
