Description

The present invention relates to a display control device for controlling the display in accordance with the touch input (touch operation), display system personage method, and program, and a storage medium body.

  2. Description of the Related Art In recent years, digital devices and the like that display on a display unit (for example, a display device) according to a touch operation are known. Such a digital device includes a touch panel for touch operation and a display control device for performing display control according to the touch operation.

  If display control is performed according to the touch operation, the user can perform an intuitive operation. Here, a display device having a touch panel is referred to as a touch panel display device.

  In the above digital device, the display control device executes a display function assigned to the button icon when a button icon generally arranged on the display screen of the touch panel display device is touch-operated.

  On the other hand, a digital camera, a photo viewer, or the like is known as a digital device, but a touch panel display device is also used in a digital camera or the like when browsing a captured image or the like. The display control device has a so-called image feed function (a type of display function) that switches the currently displayed image to another image when the displayed button icon is touched.

  For example, in a display control apparatus, when a displayed button icon is touched, the button icon display form is changed for a certain period of time (see, for example, Patent Document 1). And in patent document 1, if the button icon is touched again while the display mode of a button icon is changing, the display mode of a button icon will be changed further.

  Thus, when the touch operation is continuously performed a plurality of times on the button icon, the user can know that the display control device has continuously accepted the touch operation.

JP-A-7-160424

  As described above, in the display control device described in Patent Document 1, a button icon for image forwarding is displayed on the screen during image browsing, and image forwarding is executed when the user touches the button icon. doing.

  However, the button icon displayed on the display device inevitably partially hides the image displayed on the display device. As a result, an unfavorable situation occurs in which browsing of images is hindered by the button icon.

  In order to avoid such an inconvenience, an area (touch area) where an image can be fed by a touch operation for a predetermined time may be displayed as a guidance at the start of image browsing without always displaying a button icon. . Then, when the user performs a touch operation on a region where the image can be fed, the image feeding is executed.

  However, such an image feeding method has a problem that when a predetermined time elapses, it is impossible to accurately know where an image can be fed by a touch operation.

  In particular, if you want to continuously feed images by continuing touch operations, you may not be able to feed images continuously unless you know exactly which area the touch operation is accepted in. is there. That is, due to the movement of the finger touching the touch panel, the continuous image feed may end unconsciously, and the user may be confused.

  Such a problem may occur not only for the button icon for image feed but also for the button icon for executing another display function.

  In addition, in a small digital device such as a digital camera, the display device is small. When viewing an image on a small display device, if information (image) that is not directly related to a button icon or the like is displayed, the image itself becomes extremely difficult to see. In addition, when a touch operation is performed on a small display device, the button icon itself is extremely small, which makes it very difficult to understand which operation is selected.

An object of the present invention, without the user of the image閲list and Samatageruko, Table示制control apparatus which can accurately recognize the user the data pitch region for accepting a touch operation, the display system personage method, and program , as well as a storage medium body.

In order to achieve the above object, a display control apparatus according to the present invention includes a touch detection unit that detects a touch on a display screen of a display unit, and an image that controls the display unit to display an image on the display screen. Control for controlling to execute display control means and a first function for switching an image displayed on the display screen in response to a touch operation on a first area which is a partial area on the display screen And a first identification image indicating a range of the first area on the image displayed on the display screen in response to detection of a touch on the first area by the touch detection means. Display control means for controlling the display so that the first identification image is not displayed when the touch on the first area is no longer detected. The control means includes: Touch to the area Is continued for a predetermined time or longer and while the touch on the first area is continued, the first function is controlled to be executed continuously, and the touch on the first area is controlled. If released without continuing the predetermined time or more, it characterized that you control to run once the first function in response to the touch is released.

According to the present invention, without interfering with the image browsing Yu Za, Ru can be a touch area for accepting a touch operation accurately recognize the user.

It is a figure which shows the display screen of the display in the next image advance guidance display process shown to FIG. 4a. It is a figure which shows an example of the buttons displayed on a display in the digital camera shown in FIG.

  Hereinafter, an example of a display control apparatus according to an embodiment of the present invention will be described with reference to the drawings. In this embodiment, a digital camera having a display control device will be described as an example of a digital device. However, even if a digital device other than a digital camera is provided with a display control device, the same applies. This embodiment can be applied.

  FIG. 1 is a block diagram illustrating an example of a digital camera 100 including an example of a display control apparatus according to an embodiment of the present invention.

  Referring to FIG. 1, the illustrated digital camera 100 has a CPU (Central Processing Unit) 101. The digital camera 100 further includes an imaging unit 102, a memory 103, a display device (hereinafter simply referred to as a display) 104, an input unit 105, a recording medium drive 106, a network interface (I / F) 107, and a sensor 112. Yes. These components are connected to each other by an internal bus 111.

  The CPU 101 is an arithmetic processing device that controls the operation of the digital camera 100. For example, the CPU 101 receives an instruction from the user via the input unit 105 and executes various programs (for example, a content management program) described later. Then, the CPU 101 performs display control of the display 104.

  Thus, in the illustrated example, the CPU 101 functions as a display control device. The memory 103 is used as a work area for the CPU 101.

  The imaging unit 102 includes an imaging element (not shown) such as a CCD (Charge Coupled Device), and an optical image formed on the imaging element is converted into an electrical signal by the imaging element. The electrical signal is converted into a digital signal by the imaging unit 102 (hereinafter, this digital signal is referred to as an imaging signal).

  Then, the CPU 101 writes the imaging signal as image data on the external recording medium 108 via the recording medium drive 106.

  The display 104 is a display unit for displaying a graphic user interface described later, and images and various display items described later are displayed on the display 104.

  The input unit 105 includes a mouse that is a keyboard and a pointing device, for example. In the illustrated example, the input unit 105 has a touch panel, and the input unit 105 is used as an input device. That is, although not shown, the touch panel as the input unit 105 is arranged on the display screen of the display 104. Then, the user can execute the content management program on the CPU 101 by operating the input unit 105.

  An external recording medium 108 is inserted into the recording medium drive 106. The external recording medium 108 is, for example, a CD-ROM, DVD-ROM, or flash memory. The recording medium drive 106 reads data (including programs) stored in the external recording medium 108 and writes data to the external recording medium 108.

  In the illustrated example, it is assumed that the external recording medium 108 stores the image data obtained by the imaging unit 102 as described above as data and various programs executed by the CPU 101.

  The I / F 107 is connected to the network 110 via the communication line 109, for example. Various information on the network 110 is taken into the digital camera 100 as data via the I / F 107. Furthermore, various data including image data in the digital camera 100 can be transmitted to the network 110 via the I / F 107.

  Note that the CPU 101 can execute a program on the network 110 via the I / F 107. Therefore, the program on the network 110 can also be called a program executed by the CPU 101.

  The sensor 112 is an acceleration sensor, for example, and the attitude of the digital camera 100 is detected by the sensor 112.

  When the input unit 105 is a touch panel, the CPU 101 detects a touch operation on the touch panel. For example, the CPU 101 detects that the touch panel is touched with a finger or a pen (hereinafter referred to as touchdown). Further, the CPU 101 detects that the touch panel is touched with a finger or a pen (hereinafter referred to as touch-on).

  Further, the CPU 101 detects that the finger or the like is moved while the touch panel is touched with a finger or a pen (hereinafter referred to as a move). In addition, the CPU 101 detects that a finger or pen that has been touching the touch panel has been released (hereinafter referred to as touch-up). Then, the CPU 101 detects a state where nothing is touched on the touch panel (hereinafter referred to as touch-off).

  The touch operation on the touch panel and the position of the touch operation (hereinafter referred to as position coordinates) are notified to the CPU 101 via the internal bus 111 as a touch detection signal. The CPU 101 determines what touch operation has been performed on the touch panel according to the touch detection signal.

  The touch detection signal represents any one of the touch-down, touch-on, move, touch-up, and touch-off described above. Taking a move as an example, if the CPU 101 determines that a finger, a pen, or the like is moving on the touch panel in accordance with the touch detection signal, it determines that it is a move. The movement direction of the finger or the like on the touch panel can be determined for each vertical component / horizontal component on the touch panel according to the change in the position coordinates.

  In the illustrated example, it is assumed that when a touch-up is performed after a certain move from a touchdown on the touch panel, a series of these touch operations draws a stroke. A touch operation that draws a stroke quickly is called a flick.

  This flick is a touch operation in which a finger or the like is quickly moved by a certain distance while the finger or the like is kept touching the touch panel, and then the finger or the like is released from the touch panel. That is, the flick is a touch operation that quickly traces as if the finger is played on the touch panel.

  Therefore, the CPU 101 determines that a flick has been performed when it detects a touch-up after detecting that it has moved at a predetermined distance or more and a predetermined speed or more according to the touch detection signal.

  Further, when the CPU 101 detects that it has moved at a predetermined distance or more and less than a predetermined speed, it determines that a drag has been performed.

  Hereinafter, in the illustrated example, when the digital camera 100 is activated in the reproduction mode and the touch panel is touched, an area (touch area) in which an image can be sent is displayed in advance as guidance for a predetermined time, and then an image reproduction process is performed. The case will be described.

  FIG. 2 is a flowchart for explaining an example of the operation when the digital camera 100 shown in FIG. 1 is activated in the playback mode. Here, starting in the playback mode means, for example, when the digital camera 100 is switched from the shooting mode to the playback mode, or when the digital camera 100 is started up in the playback mode from the power-off.

  The operation of the CPU 101 in the following description is performed, for example, when the CPU 101 executes a program stored in an external recording medium.

  1 and 2, when the digital camera 100 is activated in the playback mode, the CPU 101 determines whether or not the guidance setting is on (“ON”) in the setting of the digital camera 100 (step S201). ). If it is determined that the guidance setting is on (YES in step S201), the CPU 101 displays a touch area for image feeding on the display 104 as an image feeding guidance (second guidance) for a predetermined time (step S202). : 2nd guidance presentation means). This predetermined time is, for example, about 5 seconds. That is, the CPU 101 executes the second guidance display for a predetermined time.

  FIG. 3 is a view for explaining the image feed guidance display in step S202 shown in FIG. As shown in FIG. 3, on the screen 300 of the display 104 (FIG. 1), in addition to the image 303, the word “being activated” is displayed on the lower side of the screen 300.

  Further, touch areas 301 and 302 defined by rectangles are displayed on both sides of the screen 300, respectively. The touch area 301 has a right arrow body 301a in the figure, and the touch area 302 has a left arrow body 302a in the figure. Then, the image feeding direction is defined by the directions of the arrow bodies 301a and 302a.

  In the illustrated example, when the user performs a touch operation on the touch area 301, the CPU 101 sends an image to the next image and displays the next image on the display screen of the display 104. On the other hand, when the user touches the touch area 302, the CPU 101 feeds the image to the previous image and displays the previous image on the display screen.

  Referring to FIGS. 1 and 2 again, when the image feed guidance is displayed for a predetermined time, CPU 101 executes a process in a playback mode (to be referred to as a single playback process hereinafter) (step S203). Then, when the single reproduction process ends, the CPU 101 ends the process. If the guidance setting is off in step S201, the CPU 101 proceeds to step S203 and executes single reproduction processing.

  4a and 4b are flowcharts for explaining the single reproduction process (step S203) shown in FIG.

  FIG. 5 is a diagram showing a display screen of the display 104 in the no-input state in the digital camera 100 shown in FIG.

  Here, the operation from the start in the reproduction mode until the image is displayed on the display 104 by a touch operation will be described. Here, the no-input state means a state in which only image data stored in the external recording medium 108 is displayed as an image 501 on the screen 500 of the display 104 as shown in FIG.

  Referring to FIGS. 1, 4a, and 4b, in the single reproduction process, first, the CPU 101 monitors an input event (user instruction) from the input unit 105 (event monitoring: step S401). Here, the input event includes the touch-up, touch-down, dragging, and the like described above, and further includes an operation event other than the touch operation from the input unit 105.

  When an input event occurs, the CPU 101 determines whether or not the input event is a touchdown (touchdown event) (step S402). If the input event is a touch-down event (YES in step S402), the CPU 101 holds the coordinates P at the time of touch-down in the memory 103 (step S403).

  Thereafter, the CPU 101 determines whether or not there are a plurality of reproduction target image data stored in the external recording medium 108 (step S404). If there are a plurality of reproduction target image data (YES in step S404), the CPU 101 determines whether or not the coordinate P is within the touch area for moving the image in the next direction, that is, the touch area 301. (Step S405).

  If the coordinate P is within the touch area 301 (YES in step S405), that is, if it is within the next image feed area, the CPU 101 performs a next image feed guidance display process (step S406: first guidance). Presentation means). That is, the CPU 101 executes the first guidance display.

  FIG. 6 is a diagram showing a display screen of the display 104 in the next image feed guidance display process shown in FIG. 4A.

  As shown in FIG. 6, in the next image feed guidance display processing, the CPU 101 displays only the touch area located on the right side (in FIG. 6, the touch area is indicated by reference numeral 601) on the screen 600 of the display 104. To do. That is, the CPU 101 does not display the touch area located on the left side. Here, the touch area 601 is a specific area.

  In this way, the CPU 101 displays only the touch area 601 (specific area) related to the touch operation on the screen 600 as guidance (first guidance). That is, the CPU 101 displays the touch area 601 as a specific area in an identifiable state. This allows the user to predict what processing will be performed thereafter.

  Further, since the guidance shown in FIG. 6 is displayed only when there are a plurality of reproduction target image data in step S404, the user can perform the next image feed only when there are a plurality of reproduction target image data. Can be recognized (identified).

  For example, the user can recognize whether or not there are a plurality of image data on the screen 600 shown in FIG. 6 without checking the total number of image data stored in the external recording medium 108. .

  As shown in FIG. 5, before the first guidance display described above is performed, an image is displayed in an area including a specific area in the display screen of the display 104. Then, as shown in FIG. 6, the CPU 101 displays a touch area 601, that is, a specific area, superimposed on the image displayed on the display screen.

  Referring to FIGS. 1, 4a, and 4b again, subsequently, the CPU 101 determines whether or not a predetermined time (predetermined time) has elapsed after the touchdown event (step S407: display). Control means). When the predetermined time has elapsed (YES in step S407), the CPU 101 starts image feed processing (next image feed processing) in the next direction (step S408: display control means).

  When the next image feed process is started, the CPU 101 continuously reproduces image data one by one as an image at regular intervals after a predetermined time has elapsed until an instruction to end image feed is received.

  Then, the CPU 101 monitors the input event again (step S409). If the predetermined time has not elapsed in step S407 (NO in step S407), the CPU 101 proceeds to step S409 and monitors the input event.

  If there is an input event, the CPU 101 determines whether or not the input event is a touch-up event (step S410). That is, the CPU 101 determines whether or not the touch operation (touch input) has been canceled.

  If the input event is not a touch-up event (NO in step S410), CPU 101 determines whether or not the input event is a drag event (step S411).

  If the input event is a drag event (YES in step S411), CPU 101 determines whether or not the input event is a move in touch area 601 shown in FIG. 6 (step S412). That is, the CPU 101 determines whether or not the input event is a move within the next image area.

  If the input event is a move in touch area 601 (YES in step S412), CPU 101 returns to step S407 and continues the process. On the other hand, if the input event is not a move in the touch area 601 (NO in step S412), the CPU 101 stops the next image feed process (step S413). Then, the CPU 101 hides the next image feed guidance (step S414).

  Thereafter, the CPU 101 determines whether or not to end the single reproduction process (step S415). If it is determined that the single reproduction process is to be ended (YES in step S415), CPU 101 ends the single reproduction process. On the other hand, if it is determined not to end the single reproduction process (NO in step S415), CPU 101 returns to step S401 and continues to monitor the input event.

  If the input event is not a drag event in step S411 (NO in step S411), the CPU 101 proceeds to step S413 and stops the next image feed process.

  In step S410, if the input event is a touch-up event (YES in step S410), CPU 101 determines whether or not at least one image has been fed (step S416). That is, the CPU 101 determines whether or not at least one image has been fed between the time when the touchdown event is received and the time when the touchup event is received.

  If there is no image feed (NO in step S416), CPU 101 feeds only one image in the next direction (step S417). That is, the CPU 101 performs image feeding at least once. Then, the CPU 101 proceeds to step S413 and stops the next image feeding process.

  It is unnatural that no image is forwarded when a touch-up event occurs within a predetermined time despite the start of the next image forwarding process after the touchdown event is determined. Therefore, here, when no image is fed after the touchdown event, only one image is fed to improve the operability of image feeding.

  On the other hand, if there is at least one image feed (YES in step S416), CPU 101 proceeds to step S413 and stops the next image feed process.

  In step S405 described above, if the coordinate P is not within the touch area 301 shown in FIG. 3 (NO in step S405), that is, if it is not within the next image feed area, the CPU 101 determines that the coordinate P is in FIG. It is determined whether or not it is within the touch area 302 shown (step S418). That is, the CPU 101 determines whether or not the coordinate P is within the touch area (previous image feed area) 302 for moving the image forward.

  If the coordinate P is within the touch area 302 (YES in step S418), that is, if it is within the previous image feed area, the CPU 101 performs a previous image feed guidance display process (step S419).

  In the previous image advance guidance display process, the CPU 101 displays only the touch area 302 located on the left side on the screen of the display 104 in the same manner as the next image advance guidance display process described with reference to FIG. That is, the CPU 101 does not display the touch area 301 located on the right side. Here, the touch area 302 is a specific area.

  In this way, the CPU 101 displays only the touch area 302 related to the touch operation on the display 104 as the previous image feed guidance. In this case, the previous image feed guidance is the first guidance, and the CPU 101 executes the first guidance display.

  Subsequently, the CPU 101 determines whether or not a predetermined time has elapsed after the touchdown event (step S420). When a predetermined time has elapsed (YES in step S420), CPU 101 starts image feed processing (previous image feed processing) in the forward direction (step S421).

  When the previous image feed process is started, the CPU 101 continuously reproduces image data one by one as an image at regular intervals after a predetermined time has elapsed until an instruction to end image feed is given.

  Then, the CPU 101 monitors the input event again (step S422). If the predetermined time has not elapsed in step S420 (NO in step S420), the CPU 101 proceeds to step S422 and monitors the input event.

  If there is an input event, the CPU 101 determines whether or not the input event is a touch-up event (step S423). If the input event is not a touch-up event (NO in step S423), CPU 101 determines whether or not the input event is a drag event (step S424).

  If the input event is a drag event (YES in step S424), CPU 101 determines whether or not the input event is a move (movement) in touch area 302 shown in FIG. 3 (step S425). ). That is, the CPU 101 determines whether or not the input event is a move in the previous image area.

  If the input event is a move in touch area 302 (YES in step S425), CPU 101 returns to step S420 and continues processing. On the other hand, if the input event is not a move in the touch area 302 (NO in step S425), the CPU 101 stops the previous image feed process (step S426). Then, the CPU 101 hides the previous image feed guidance (step S427).

  Thereafter, the CPU 101 proceeds to step S415 to determine whether or not to end the single reproduction process.

  If the input event is not a drag event in step S424 (NO in step S424), the CPU 101 proceeds to step S426 and stops the previous image feed process.

  In step S423, if the input event is a touch-up event (YES in step S423), the CPU 101 determines whether at least one image has been fed (step S428). That is, the CPU 101 determines whether or not at least one image has been fed between the time when the touchdown event is received and the time when the touchup event is received.

  If there is no image feed (NO in step S428), CPU 101 feeds only one image forward (step S429). Then, the CPU 101 proceeds to step S426 and stops the previous image feed process.

  On the other hand, if there is at least one image feed (YES in step S428), CPU 101 proceeds to step S426 and stops the previous image feed process.

  By the way, if the input event is not a touch-down event in the above-described step S402 (NO in step S402), the CPU 101 determines whether the input event is an input other than touch in the touch area (step S430). ). That is, the CPU 101 determines whether or not the input event is an event other than touch-related events.

  If the input event is an event other than touch-related (YES in step S430), CPU 101 performs processing according to the input event (other processing: step S431). In step S431, a process is performed for a touchdown when the input event from the input unit 105 other than the touch panel or the touched coordinate P is outside the areas 301 and 302 shown in FIG.

  For example, when the center of the display 104 is touched, the CPU 101 performs an enlargement process on the image displayed on the display 104. In the case of an input event from the input unit 105 other than the touch panel, the CPU 101 changes the screen displayed on the display 104 to a thumbnail screen.

  If the input event is not an event other than touch-related (NO in step S430), CPU 101 proceeds to step S415 and determines whether or not to end the single reproduction process.

  If there is not a plurality of reproduction target image data in step S404 (NO in step S404), the CPU 101 proceeds to step S431 and performs the above-described processing.

  In step S418, if the coordinate P is not in the touch area 302 (NO in step S418), that is, if it is not in the previous image feed area, the CPU 101 proceeds to step S431, and the above-described processing is performed. Perform the process.

  As described above, during the single reproduction process, the CPU 101 performs the processes of steps S407 to S414 and steps S416 and S417. Therefore, for example, when a touchdown is performed in the touch area 301 or 302 shown in FIG. 3 and dragging outside the touch area 301 or 302 in the touch-on state to perform other processing, the CPU 101 performs steps S407 to S414. The processes in steps S416 and S417 are selectively performed. As a result, the CPU 101 prioritizes other processes without performing the image feed process.

  For example, assume that the CPU 101 performs a display process for displaying a thumbnail image list when flicking leftward in FIG. In this case, if the position of the dutch down is within the touch area 301 or 302, not the thumbnail image list display process but the image feed process in the next direction will be performed. Such a process is contrary to the user's intention, and in order to avoid such a process, the processes in steps S407 to S414 and steps S416 and S417 are selectively performed to make the user operation comfortable. I have to.

  FIG. 7 is a diagram showing an example of buttons displayed on the display 104 in the digital camera 100 shown in FIG.

  For example, when only the touch area 601 shown in FIG. 6 is displayed, instead of displaying the touch area 601, the CPU 101 displays a MUNU (menu) area 701, FUNC on the screen 700 of the display 104 as shown in FIG. A (function) area 702 and a DISP (display) area 703 may be displayed. As described above, when the MUNU area 701, the FUNC area 702, and the DISP area 703 are displayed on the screen 700 of the display 104, the user can easily visually recognize, that is, identify the operation.

  As is clear from the above description, the touch area displayed on the display screen of the display 104 defines the execution of a predetermined display function, and the display functions defined by each other are different. Further, the CPU 101 functions as a first guidance presentation unit that performs a first guidance display, and also functions as a second guidance presentation unit that performs a second guidance display. Furthermore, the CPU 101 also functions as a display control unit.

  In this way, in the display control apparatus according to the embodiment of the present invention, the user is informed of the effective range of image advance in advance, so that image advancement can be performed without displaying extra information during image viewing. it can. Furthermore, since the processing corresponding to the touch area can be visually recognized even during the touch operation, the user can reliably perform the operation.

  As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to these embodiment, Various forms of the range which does not deviate from the summary of this invention are also contained in this invention.
