  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a system configuration diagram showing an electronic apparatus 1 according to an embodiment of the present invention.

[Example 1]
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

  In the present embodiment, as an example of the electronic apparatus 1, a description will be given of a state in which the page information of a document is displayed on the image display unit 2 on a portable information apparatus such as an electronic book reader, a smartphone, or a tablet computer. The document described in this case indicates a document, PDF, image file, or the like that can be browsed by an electronic book, word processor software, spreadsheet software, image browsing software, or the like.

  First, a system configuration diagram of an electronic apparatus 1 to which the present invention is applied shown in FIG. 1 will be described. As a supplement, an external view from the front of the electronic device 1 is shown in FIG. 2 (a), and an external view from below is shown in FIG. 2 (b).

  As shown in FIG. 1, the electronic apparatus 1 includes an image display unit 2, a recording medium 3, a displacement device 4, a touch detection unit 5, an image control unit 6, and a system control unit 7 that performs overall control. The image display unit 2 acquires and outputs image information from an image control unit 6 (described later) to a liquid crystal display (LCD) or the like disposed on one surface of the exterior surface of the electronic device 1.

  The recording medium 3 is a removable recording device such as a memory card that can be attached to and detached from the electronic device 1, a nonvolatile memory such as a flash memory built in the electronic device 1, and a magnetic storage device such as a hard disk drive. The recording medium 3 stores a document application, and also stores document information that can be used by the application. The document information is accompanied by page information 3a. The displacement device 4 and the touch detection means 5 will be described. The displacement device 4 and the touch detection means 5 may use the configuration described in the publicly known special table 2011-508935.

  The displacement device 4 and the touch detection means 5 are made of a transparent or translucent material, and both are arranged substantially in parallel so as to cover the display surface of the image display unit 2. A displacement device 4 is disposed at an arbitrary position on the front surface of the image display unit 2, and touch detection means 5 is disposed on the front surface of the displacement device 4. In the displacement device 4, an internal cavity is expanded based on a command from the system control unit 7, and a specific area of the surface is deformed as illustrated in FIG. 2, so that the flexible sheet of the touch detection unit 5 is deformed. Thus, at least one or more convex surfaces 4 a and convex surfaces 4 b are formed on the touch detection means 5.

  In the displacement device 4, each specific area is deformed based on a command signal for each specific area of the system control unit 7. In the description of the first embodiment, each specific region is two places shown on the convex surfaces 4a and 4b. Based on the command signal of the system control unit 7, the convex surfaces 4a and 4b of each specific region can be deformed from a flat surface to a convex surface and from the convex surface to the flat surface. Each specific region can be deformed to an arbitrary height such as 0.1H, 0.2H, 0.5H, 0.7H, etc., which are the step values, assuming that the maximum height of the convex surface is H.

  When the touch detection unit 5 is pressed by touching an arbitrary position with a finger or the like, the coordinates of the touched position are detected, and the coordinate information is transmitted to the system control unit 7. The system control unit 7 performs predetermined processing. Execute. Based on the coordinate information, the system control unit 7 determines what is selected from the various functions displayed on the image display unit 2 and operates the function according to the selection.

  The material of the touch detection means 5 is an elastic flexible sheet. As the specific area of the displacement device 4 is deformed to form a convex surface, the sheet is also deformed to form the convex surface. The touch detection unit 5 is disposed so as to overlap the image display unit 2 via the displacement device 4, and the position of the touch detection unit 5 on the panel and the position of the image display unit 2 on the display screen correspond one-to-one.

  In addition, you may integrate the image display part 2, the displacement device 4, and the touch detection means 5 as a single structure. In addition, the displacement device 4 may have a configuration described in Japanese Patent Application Laid-Open Nos. 2009-181198 and 2006-285785, which shows a different configuration from the above-mentioned publication (special table 2011-508935).

  The image control unit 6 acquires image information of a document stored in the recording medium 3, captured image information, image information acquired from the Internet, and the like, and performs image processing on the acquired image information. Two examples of image processing contents of the image processing unit 6 are illustrated. The first point is that when the specific area of the displacement device 4 forms a convex surface, the image control unit 6 has a problem that, from the user's viewpoint, the image around the convex surface is distorted due to distortion or color misregistration. Arise. In order to solve the problem, the acquired image information is corrected and output to the image display unit 2.

  The second point is that the image control unit 6 changes only the image information around the convex portion to a different background color in order to highlight the convex surface of the specific area of the displacement device 4, or the paper surface at the time of page turning is deformed. The completed state is output as image information. The image control unit 6 does not necessarily have to perform image processing on the acquired image information. For example, the acquired image information may be displayed on the image display unit 2 as it is.

  The system control unit 7 controls the entire system and has functions of a CPU and a memory (ROM, RAM). The system control unit 7 executes a program stored in the memory in accordance with an input signal from a touch operation to the touch detection unit 5, a power switch (not shown), a fixed switch, or the touch detection unit 5, and the electronic device 1 Are controlled to perform predetermined processing. After the user selects and activates an application such as a document, the system control unit 7 switches to an operation method according to the application. For example, when the user performs a touch operation on the touch detection unit 5, an enlarged display of document information, a page turning operation, or the like is executed.

  Next, a processing flow of the system control unit 7 for allowing the user to recognize the thickness due to the page by deformation of the displacement device 4 will be described with reference to FIG.

  S101 is the start of the processing flow, which is a state in which a power switch (not shown) of the electronic device 1 is turned on and a document application stored in the recording medium 3 is activated. The process proceeds to S102.

  In step S102, the document information and page information 3a stored in the recording medium 3 are read. At that time, if there is a history of browsing the document information in the past, the last viewed page at that time is output to the image display unit 2. When there is no browsing history, it outputs to the image display part 2 from the 1st page.

FIG. 2C shows the state of the electronic device 1 in S102. The right spread page number is n, and the left spread page number is n + 1. Also, it is assumed that the document information is read when the left facing page is turned. Moreover, two places of the specific area | region shown in FIG.2 (c) are the places shown with the broken-line display of the round frame, and form the flat surfaces 4a and 4b.
The process proceeds to S103.

  S103 calculates the height which changes the displacement device 4 from a flat surface to a convex surface according to the page information 3a from the calculating part stored in the system control part 7. FIG. The height of the convex surface 4a of the displacement device 4 shown in FIG. 2 (b) is calculated based on formula (1) described later, and the height of the convex surface 4b is calculated based on formula (2) described later.

In order to explain the calculation method of the calculation unit, a description will be given using a plurality of parameters. The parameters are the right spread page number n, the left spread page number n + 1, the total number of pages N, and the maximum height H of the convex surface of the displacement device 4. Further, the calculated output value is the height H _R of the convex surface 4a provided on the right facing page shown in FIG. 2B and the height H _L of the convex surface 4b provided on the left facing page. From this, the calculation method of a calculating part is shown in Formula 1 and Formula 2.

H _R = n × H ÷ N (Formula 1)
H _L = (N − ((n + 1) −1)) × H ÷ N − (Formula 2)
From this, when the page number on the right is n = 1 and the total number of pages N = 100,
H _R = 0.01H, H _L = 0.99H
Is calculated.

If the page number on the right is n = 30 and the total number of pages N = 100,
H _R = 0.30H, H _L = 0.70H
Is calculated.

  In addition, the said Formula (1) and Formula (2) are examples of the calculation method of a calculating part, and you may use a different calculation method. The process proceeds to S104.

In S104, based on the output values H _R and H _L calculated in S103, a command for forming the convex surfaces 4a and 4b from the flat surface to the displacement device 4 is transmitted.

  S105 is a state in which at least one specific region of the displacement device 4 forms a convex surface. From this state, when the page information 3a is changed by the user's touch operation on the touch detection means 5, the processing from S102 to S104 may be repeated.

  In addition, in the form of Example 1 mentioned above, the shape of the specific area was shown with the round shape. As a different embodiment, a square shape, a rectangular shape, a triangular shape, a barrel shape, or the like different from the round shape may be used.

  In S103 and S104 of the above-described embodiment, the height of the specific region of the displacement device 4 is calculated to form the convex surfaces 4a and 4b. As a different embodiment, instead of calculating the height of the specific region, as shown in FIGS. 4A and 4B, in S103, based on the page information, the size of the convex surfaces 4c and 4d of the displacement device 4 You may form the convex surfaces 4c and 4d which calculated an area and varied the magnitude | size and area. At this time, the height of the specific region may be an arbitrary height.

  As an effect of the first embodiment, the user can easily recognize the thickness of the document information page and, at the same time, can save space for the image information indicating the thickness of the document information page.

[Example 2]
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS.

  The same parts as those in the first embodiment are omitted. In the second embodiment, when the displacement device 4 forms a convex surface in the first embodiment, a flow when a user performs a page turning operation by pressing the convex surface will be described.

  When the user depresses and deforms the area of the displacement device 4 having the convex surface and the touch detection means 5 having the convex surface, the displacement device 4 detects the amount of displacement and performs system control on the detected value. Send to part 7. FIG. 5A shows a state where the user is pressing the displacement device 4. When the detected value of the displacement amount of the displacement device 4 is acquired, the system control unit 7 calculates the number of pages corresponding to the detected value, and then performs a page turning operation and is displayed on the image display unit 2. The document information page is switched. FIG. 5B shows the relationship between the detected value and the page turning number.

Shown in FIG. 5 (b), 0 from H _R illustrates the displacement amount of the right facing displacement device 4. Cases 1 and 2 indicate setting patterns of the detection value and the number of page turns per unit time. In case1, it detects the touch to the touch detection unit 10, the displacement amount of the displacement device 9 if was H _R, executes turning two pages of page. 0.6H _R 4 pages displacement from 0.9H _R, 0 is the 8 pages displacement is 0.2 H _R 6 pages from 0.5H _R, the amount of displacement from 0.1H _R, displacement The page turning amount is increased approximately in proportion to the amount.

In case2, detects the touch to the touch detection unit 10, when the displacement amount of the displacement device 9 was H _R, page turning is not executed. 0.8H _R 2 pages displacement from 0.9H _R, 0.6H _R 4 pages displacement from 0.7H _R, 0.4H _R 8 pages displacement from 0.5H _R The amount of page turning is increased by approximately squaring the displacement amount.

  Note that the displacement amounts indicated by case1 and case2 are displacement amounts per unit time, and the page turning amount may further increase as the time during which the user presses the displacement device 4 becomes longer. In addition, even if it is not the displacement amount of the displacement device 4 demonstrated by case1 and case2, page turning amount is detected according to one value, such as pressure, speed, acceleration, etc. which acted on the displacement device 4, and page turning operation | movement May be executed. Note that the user may appropriately set the relationship between the displacement amount of the displacement device 9 and the page turning amount and the unit time.

  With reference to FIG. 6, the processing flow of the system control unit 7 in the second embodiment will be described.

  S201 is the state of S105 in the processing flow of the first embodiment. At least one specific region of the displacement device 4 is in a state where a convex surface is formed. The process proceeds to S202.

  In step S202, it is determined whether the user has performed a touch operation on the area of the touch detection unit 5 on which the convex surface is formed. When the touch operation is performed, the displacement amount of the displacement device 4 is detected, and the detected value is transmitted to the system control unit 7. The process proceeds to S203. When the touch operation is not performed, the process proceeds to S208.

  In S203, the system control unit 7 acquires a detection value. The process proceeds to S204.

  S204 resets the timer which measures the time which processes the control flow of Example 2. FIG. The process proceeds to S205.

  In S205, a page turning amount corresponding to the detected value is calculated. The process proceeds to S206.

  In S206, a page turning operation is instructed based on the value calculated in S205, and an instruction to switch the page of the document information displayed on the image display unit 2 is transmitted. An image diagram during the page turning operation is shown in FIG. The process proceeds to S207.

  In step S207, it is determined whether the timer that measures the time for processing the control flow of the second embodiment has passed an arbitrary time. When an arbitrary time has elapsed, the process proceeds to S202.

  S208 is a state in which the user has not touched the area of the touch detection unit 5 on which the convex surface is formed, and the process proceeds to S201 and the same processing is repeated.

  The effect of the second embodiment will be described. In a known technique, when a plurality of pages are turned, a scroll bar displayed on the image display unit 2 is scrolled left and right and up and down. For this purpose, the user first visually recognizes the image display unit 2, then recognizes the scroll bar, then touches the scroll bar carefully so as not to malfunction by touching other than the scroll bar, The scroll bar was sliding in the horizontal and vertical directions.

  In the second embodiment, since the convex surface protrudes from the touch detection means 4, the convex surface for performing page turning can be recognized at the moment when the image display unit 2 is viewed, and the convex surface is simply pressed down. Then you can perform page turning. This facilitates page turning operability and at the same time reduces time. In the above-described embodiment, the processing method in the case of two-page spread display has been described. As a different embodiment, processing can be performed even with a two-page spread display.

Even in the case of the two-page spread display shown in FIG. 8A, the displacement device 4 may be changed from the flat surface to the convex surfaces 4e and 4f by performing substantially the same processing as in the first embodiment. A supplementary description will be given of the calculation method of the calculation unit in the case of the one-page spread display shown in FIG. The parameters are page number n, total page number N, and maximum height H of the convex surface of the displacement device 4. The output values are the height H _R2 of the convex surface 4e provided on the right side of the page and the height H _L2 of the convex surface 4f provided on the left side of the page. From this, the heights H _R2 and H _L2 are
H _R2 = n × H ÷ N ― (Formula 3)
H _L2 = (N−n) × H ÷ N (Formula 4)
And it is sufficient.

  In the above-described embodiment, the state where the electronic apparatus 1 is fixed has been described. As a different embodiment, a processing method when document information displayed on the image display unit 2 is rotated as the electronic apparatus 1 is rotated will be described. When the electronic apparatus 1 is fixed in the state shown in FIG. 8A, the specific areas 4e and 4f of the displacement device 4 are set as control targets of the flow, and the specific areas 4g and 4h are set as non-control targets. Always form a flat surface. On the other hand, when the electronic device 1 is fixed in the state shown in FIG. 8B rotated 90 degrees in the CCW direction, the specific areas 4e and 4h of the displacement device 4 are set as the control targets of the flow, and the specific areas 4e 4g should always form a flat surface as a non-control target.

  In the above-described embodiment, the case where the present invention is applied to the imaging apparatus 1 has been described as an example. The electronic device 1 in the present invention can be applied to a product including a camera, a mobile phone, a tablet device, a PDA, a game device, a music player, a personal computer, and a touch panel and an imaging lens.
