  • DETAILED DESCRIPTION First Exemplary Embodiment
  • [0018]
    Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. First, the configuration and the operation of a first exemplary embodiment will be described in detail.
  • [0019]
    FIG. 1 shows the hardware configuration of an image display device according to an exemplary embodiment.
  • [0020]
    An image display device 10 according to the exemplary embodiment is a computer device such as a smartphone, a tablet, a cellular phone, or a personal computer (PC), for example.
  • [0021]
    As shown in FIG. 1, the image display device 10 includes a central processing unit (CPU) 11, and a memory 12 serving as a storage unit. The CPU 11 executes various types of software such as an operating system (OS) and applications. The memory 12 is a storage region in which the various types of software, data for execution of such software, etc., are stored. The image display device 10 further includes a communication interface 13 (hereinafter referred to as “communication I/F”) for external communication, and an image display 14 that displays an image. The image display device 10 may include a hard disk drive (HDD) or a flash memory serving as a storage unit. The HDD or the flash memory stores data input to the various types of software, data output from the various types of software, etc. The image display device 10 may further include an input device such as a keyboard or a mouse. The CPU 11 and the memory 12 may be considered as a controller that decides an image to be displayed on the image display 14 and that controls display of the decided image.
  • [0022]
    FIG. 2 illustrates the image display 14.
  • [0023]
    The image display device 10 is illustrated as a so-called smartphone. A touch panel is adopted as the image display 14. Therefore, the image display 14 includes a liquid crystal panel 141 serving as an example of a display, and a position detection section (not shown) that detects the position at which a contacting object contacts the liquid crystal panel 141 when the contacting object contacts the liquid crystal panel 141. The contacting object is typically a user's finger or a stylus pen. In the exemplary embodiment, the touch panel for use as the liquid crystal panel 141 is not specifically limited, and may be of a variety of types such as a resistance-film type and an electrostatic capacitance type.
  • [0024]
    In the thus configured image display device 10, content (information content) may be displayed as an image in a predetermined region of the liquid crystal panel 141. In the case where the content extends over plural pages (plural sheets), in general, each page is displayed on the liquid crystal panel 141, and the user views the image while switching images from page to page. That is, in the liquid crystal panel 141, a part of the content is displayed as an image for each page in the predetermined region, and the image is switched so as to display the part of the content in a predetermined order. This corresponds to a case where the content is electronic book data and the user views the content while switching images from page to page, for example.
  • [0025]
    In the image display device 10 such as a smartphone shown in FIG. 2, switching between images is performed by performing a flicking operation in a predetermined direction with a contacting object, such as a finger or a stylus pen, being kept in contact with the liquid crystal panel 141. That is, the image displayed on the liquid crystal panel 141 is switched to another image when the user flicks the contacting object at a location at which the image is displayed on the liquid crystal panel 141.
  • [0026]
    In FIG. 2, a user's finger is shown as the contacting object, and an image P1 is shown as the image currently being displayed. In this case, when the image P1 displayed around the center of the liquid crystal panel 141 is flicked leftward as shown in FIG. 2, an image P2 for the next page is moved to the center of the liquid crystal panel 141 to be displayed in place of the image P1. Conversely, when the image P1 being displayed is flicked rightward, an image P0 for the previous page is moved to the center of the liquid crystal panel 141 to be displayed in place of the image P1. The user may continuously view images by continuously performing flick operations to successively switch images. Viewing the content through such flick operations allows handling electronic data as if handling paper data, improving convenience for the user.
  • [0027]
    If there are a large number of pages, however, it is necessary to repeat flick operations over and over while viewing the content on the liquid crystal panel 141, which may be bothersome for the user. This may further increase the physical burden on the user.
  • [0028]
    A slide show function is generally known as a method to allow viewing content including image data such as photographs. When the slide show function is used, preview images of the photographs are displayed on the liquid crystal panel 141. The user performs an operation to start a slide show of the preview images being displayed. This causes switching between the preview images displayed on the liquid crystal panel 141, allowing the user to successively view the photographs. If the switching speed is constant and not changed, however, preview images for which check is scarcely required may take considerable time. In the case where a larger number of photographs are to be viewed, in addition, the viewer may be at a loss because he/she does not know where the photograph being viewed is in the entire content, which may be inconvenient.
  • [0029]
    In the exemplary embodiment which is intended to address the foregoing issue, when the user continuously performs a predetermined number of flick operations or more, switching between subsequent pages is performed automatically as described below.
  • [0030]
    FIG. 3 shows a first functional configuration example of a controller according to the exemplary embodiment.
  • [0031]
    As shown in FIG. 3, the controller according to the exemplary embodiment includes a position acquisition section 21, an image switch determination section 22, a speed storage section 23, an image switch measurement section 24, and an image display controller 25.
  • [0032]
    The position acquisition section 21 acquires the position at which a contacting object such as a user's finger contacts the liquid crystal panel 141 (see FIG. 2) when the contacting object contacts the liquid crystal panel 141. That is, as discussed above, the image display 14 is a touch panel, and includes a position detection section that detects the position at which the contacting object contacts the liquid crystal panel 141. Therefore, the position acquisition section 21 may acquire the position at which the contacting object contacts the liquid crystal panel 141 from the position detection section.
  • [0033]
    The image switch determination section 22 determines whether or not to switch the image displayed on the liquid crystal panel 141 in accordance with variations in position acquired by the position acquisition section 21 (which may also be referred to as “position detected by the position detection section”). That is, the image switch determination section 22 determines whether or not an operation performed on the liquid crystal panel 141 by the contacting object is a flick operation. In the case where the user performs a flick operation, the image switch determination section 22 determines the direction in which the position at which the contacting object contacts the liquid crystal panel 141 is moved, and determines whether the image is switched to an image for the previous page or an image for the next page.
  • [0034]
    The speed storage section 23 stores the image switching speed in the case where the image switch determination section 22 determines to switch the currently displayed image to another image.
  • [0035]
    The image switch measurement section 24 counts the number of times switching between images is performed by performing flick operations by the user. The image switch measurement section 24 counts the number of flick operations performed continuously. In the case where a different operation is performed in between the flick operations, the number of flick operations counted is reset to “0”.
  • [0036]
    The image display controller 25 acquires from the image switch measurement section 24 the number of flick operations continuously performed by the user. When flick operations are performed continuously a predetermined number of times or more, that is, the image is continuously switched a predetermined number of times or more, switching between subsequent images is continuously performed on the basis of the speed stored in the speed storage section 23. That is, in the case where the user continuously performs a predetermined number of flick operations or more, the image displayed on the liquid crystal panel 141 is automatically switched. The image display controller 25 switches images at the speed stored in the speed storage section 23.
  • [0037]
    FIG. 4 is a flowchart illustrating operation of the controller shown in FIG. 3.
  • [0038]
    Operation of the controller according to the exemplary embodiment will be described below with reference to FIGS. 3 and 4. As a precondition for performing the following process, an image that may be switched by performing a leftward or rightward flick operation is displayed in advance on the liquid crystal panel 141.
  • [0039]
    First, when the contacting object, such as a user's finger, contacts the liquid crystal panel 141 of the image display 14, the position detection section of the image display 14 detects the position of contact. The position acquisition section 21 of the controller acquires the position of contact from the position detection section (step 101).
  • [0040]
    Next, the image switch determination section 22 determines whether or not an operation performed by the contacting object at a location on the liquid crystal panel 141 at which the image described above is displayed is a flick operation (step 102). In the case where the image switch determination section 22 determines that a flick operation is performed (Yes in step 102), it is determined in the exemplary embodiment that the operation is an operation performed by the user to switch images. It is determined whether the user desires to switch the image to an image for the previous page or an image for the next page in accordance with whether a leftward flick operation or a rightward flick operation is performed. That is, in the case where a leftward flick operation is performed, it is determined that the user desires to switch the image to an image for the next page. In the case where a rightward flick operation is performed, on the other hand, it is determined that the user desires to switch the image to an image for the previous page. In the case where the image switch determination section 22 determines that a flick operation is not performed (No in step 102), the process returns to step 101.
  • [0041]
    Next, the speed storage section 23 stores the speed at which the flick operation is performed (step 103). Specifically, when the user performs the flick operation, the position of contact acquired by the position acquisition section 21 is moved. The speed at which the flick operation is performed may be calculated, for example, based on how much distance the contacting object is moved over a predetermined time period.
  • [0042]
    Next, the image switch measurement section 24 adds “1” to the number of flick operations performed by the user (step 104). The initial value of the number of flick operations counted by the image switch measurement section 24 is “0”. The image switch measurement section 24 counts number of flick operations performed continuously. Therefore, in the case where a different operation is performed in between the flick operations, the number of flick operations counted is reset to the initial value “0”.
  • [0043]
    The image switch measurement section 24 determines whether or not the number of flick operations counted has reached a predetermined value (step 105).
  • [0044]
    In the case where the number of flick operations counted has not reached the predetermined value (No in step 105), the image display controller 25 switches the image displayed on the liquid crystal panel 141 to an image for the next page or an image for the previous page in accordance with the results of the determination performed by the image switch determination section 22 (step 106). After that, the process returns to step 101.
  • [0045]
    In the case where the number of flick operations counted has reached the predetermined value (Yes in step 105), on the other hand, the image display controller 25 automatically switches subsequent images (step 107). The switching speed used at this time is decided on the basis of the speed stored in the speed storage section 23.
  • [0046]
    If settings are made to automatically switch images when the number of flick operations counted has reached three, for example, the first three switches between images are performed by the user by performing flick operations. That is, images are switched manually. The fourth and subsequent switches between images are automatically performed by the image display controller 25 on the basis of the speed stored in the speed storage section 23.
  • [0047]
    In the exemplary embodiment, for example, switches between images are performed according to the settings described above as follows:
  • [0048]
    (First image switch (manual))
    • (Second image switch (manual))
    • (Third image switch (manual))
    • (Fourth image switch (automatic, at the same switching speed as the speed of the first image switch))
    • (Fifth image switch (automatic, at the same switching speed as the speed of the second image switch))
    • (Sixth image switch (automatic, at the same switching speed as the speed of the third image switch))
  • [0054]
    (Thereafter, the fourth to sixth image switches are repeated.)
  • [0055]
    When the image display controller 25 operates to automatically switch images, the image switch determination section 22 determines whether or not the user has performed a predetermined operation to stop operation of switching between images (step 108). The stop operation may be an operation to tap at a location at which an image is to be displayed, for example.
  • [0056]
    In the case where the image switch determination section 22 determines that a stop operation has been performed (Yes in step 108), the image display controller 25 stops operation to switch images (step 109). This allows the user, for example, to check the content at the location of the stop. In addition, displaying the image as enlarged at the location of the stop may make it further easier for the user to check the content.
  • [0057]
    In the case where the image switch determination section 22 determines that a stop operation has not been performed (No in step 108), the image switch determination section 22 further determines whether or not the user has performed an additional flick operation (step 110).
  • [0058]
    In the case where the user has performed an additional flick operation (Yes in step 110), it is determined in the exemplary embodiment that the user has performed the operation for the purpose of changing the image switching speed. The speed storage section 23 additionally stores the speed at which the additional flick operation is performed (step 111). The image display controller 25 switches subsequent images at the speed stored in the speed storage section 23 (step 112). In other words, in the case where the image switch determination section 22 determines to further switch the image displayed on the liquid crystal panel 141 when the image display controller 25 is continuously switching the image, the speed storage section 23 additionally stores the image switching speed, and the image display controller 25 switches subsequent images at the speed additionally stored in the speed storage section 23. After that, the process returns to step 108. In the case where the user has not performed an additional flick operation (No in step 110), the process also returns to step 108.
  • [0059]
    In the example discussed above, the user performs an additional flick operation to change the image switching speed when the image display controller 25 operates to automatically switch images. However, the exemplary embodiment is not limited thereto. For example, a speedometer 141 a may be displayed on the liquid crystal panel 141 as shown in FIG. 5, and a button 141 b provided in the speedometer 141 a to indicate the switching speed may be operated to change the image switching speed.
  • [0060]
    In the example discussed above, a flick operation is used as an example of an operation performed by the user to switch the image displayed on the liquid crystal panel 141. However, the exemplary embodiment is not limited thereto. A different operation such as a drag operation may also be used.
  • Second Exemplary Embodiment
  • [0061]
    FIG. 6 shows a second functional configuration example of a controller according to an exemplary embodiment.
  • [0062]
    As shown in FIG. 6, the controller according to the exemplary embodiment includes a position acquisition section 21, an image switch determination section 22, a speed storage section 23, an image switch measurement section 24, an image display controller 25, a demarcation determination section 26, a demarcation storage section 27, and a time measurement section 28.
  • [0063]
    The respective functions of the position acquisition section 21, the image switch determination section 22, the speed storage section 23, and the image switch measurement section 24 are the same as the functions of those in FIG. 3, and thus are not described here.
  • [0064]
    The demarcation determination section 26 determines a demarcation portion in the content in accordance with predetermined demarcation conditions.
  • [0065]
    In the case where the content to be displayed is a preview image of a document to be printed, for example, the demarcation conditions may be set in accordance with document size, color/monochrome mode, double-sided/single-sided printing, document direction (portrait/landscape), font, number of pages to be printed on a single page (number of pages for N-Up printing), destination tray for paper ejection, and document reading location (platen glass/auto document feeder (ADF)), and may be set to indicate a point of change between folders containing the data to be printed, for each predetermined page, to indicate a case where the recognition ratio of optical character recognition (OCR) is low, to indicate a case where the document is upside down, etc.
  • [0066]
    In the case where the content to be displayed is a preview image of a photograph, the demarcation conditions may be set in accordance with date and time of capture (month, week, and time), to indicate a point of change between folders containing the photograph data, to indicate a point of change between cameras used to capture the photograph, etc.
  • [0067]
    The image display controller 25 continuously switches subsequent images on the basis of the speed stored in the speed storage section 23 when the image is continuously switched a predetermined number of times or more as discussed above. In the second exemplary embodiment, further, information on the demarcation portion determined by the demarcation determination section 26 is additionally displayed on the liquid crystal panel 141. That is, in the case where the image to be displayed is a page matching the demarcation conditions determined by the demarcation determination section 26, the content of the demarcation conditions etc. is displayed on the liquid crystal panel 141. In the second exemplary embodiment, such information is displayed through a pop-up indication.
  • [0068]
    The demarcation storage section 27 stores information on the demarcation portion determined by the demarcation determination section 26. The information on the demarcation portion is stored as history information as discussed later in detail.
  • [0069]
    The time measurement section 28 measures the time since the pop-up indication is started as discussed later in detail. When a predetermined time elapses, the image display controller 25 hides the pop-up indication.
  • [0070]
    FIG. 7 illustrates a case where information on a demarcation portion is displayed through a pop-up indication.
  • [0071]
    As shown in FIG. 7, a “name list B” document is currently displayed as page 4 on the liquid crystal panel 141. If the “name list B” document falls on a point of change between folders, such information is indicated by a pop-up 141 c saying “‘NAME LIST B’ ON PAGE 4 AND SUBSEQUENT DOCUMENTS ARE DOCUMENTS FROM xx FOLDER”. This may inform the user that page 4 being displayed corresponds to a demarcation portion and that the demarcation portion corresponds to a shift between folders, in addition to informing the user of the name of the folder. Display of the pop-up 141 c allows the user to recognize that the corresponding portion needs attention for some reason.
  • [0072]
    When the user taps on the pop-up 141 c, operation to automatically switch images is stopped, and an image for the page corresponding to the demarcation portion displayed through the pop-up 141 c is displayed on the liquid crystal panel 141.
  • [0073]
    The pop-up 141 c is displayed for a predetermined time, and thereafter hidden. However, information displayed through a pop-up indication is stored to enable the user to check the information later as history information. In the example of FIG. 7, a history check button 141 d is provided at the upper right of the liquid crystal panel 141. When the user taps on the history check button 141 d, a history list such as that shown in FIG. 8 is displayed on the liquid crystal panel 141. In FIG. 8, the page number (indicated as “PAGE”) of each demarcation portion, the title of each document, and information on each demarcation portion (indicated as “DESCRIPTION”) are displayed in a list in the order of pages. In the case where there is any item that the user desires to check, he/she taps on the relevant item on the screen shown in FIG. 8. As a result, the image displayed on the liquid crystal panel 141 returns to the image shown in FIG. 7, and an image for the page corresponding to the selected demarcation portion is displayed on the liquid crystal panel 141.

  • [0079]
    In the case where the image switch determination section 22 determines that a stop operation has not been performed (No in step 208), the demarcation determination section 26 determines whether or not a page displayed each time the image is switched matches predetermined demarcation conditions (step 210). When the page matches the demarcation conditions (Yes in step 210), information on a demarcation portion is displayed on the liquid crystal panel 141 by a predetermined method such as a pop-up indication (step 211). The demarcation storage section 27 stores information on the demarcation portion determined by the demarcation determination section 26 (step 212).
  • [0080]
    In the case where the page does not match the predetermined demarcation conditions (No in step 210), the process returns to step 208.
  • [0081]
    The time measurement section 28 measures the time since the pop-up indication is started to determine whether or not a predetermined time has elapsed (step 213). When a predetermined time has elapsed (Yes in step 213), the image display controller 25 hides the pop-up 141 c (step 214). After that, the process returns to step 208.
  • [0082]
    When a predetermined time has not elapsed (No in step 213), it is determined whether or not the pop-up 141 c has been tapped on (step 215). In the case where the pop-up 141 c has been tapped on (Yes in step 215), the image display controller 25 has the page for the demarcation portion corresponding to the pop-up 141 c displayed in a stationary state (step 216). In the case where the pop-up 141 c has not been tapped on (No in step 215), the process returns to step 213.
