It is a block diagram which shows schematic structure of the display control apparatus to which this invention is applied. It is a flowchart explaining the control procedure of the display control apparatus to which this invention is applied. It is a figure explaining the example of a display of the screen of the display control apparatus to which this invention is applied.

(First embodiment)
FIG. 1 is a block diagram showing a schematic configuration of a display control apparatus embodying the present invention.
In FIG. 1, a photographing lens 103 is a lens group including a zoom lens and a focus lens. The shutter 101 is a shutter having an aperture function. The imaging unit 22 is an imaging device configured with a CCD, a CMOS device, or the like that converts an optical image into an electrical signal. The A / D converter 23 converts an analog signal into a digital signal. The A / D converter 23 is used to convert an analog signal output from the imaging unit 22 into a digital signal.

  The barrier 102 covers the imaging system including the imaging lens 103 of the digital camera 100, thereby preventing the imaging system including the imaging lens 103, the shutter 101, and the imaging unit 22 from becoming dirty or damaged.

  The image processing unit 24 performs resizing processing such as predetermined pixel interpolation and reduction and color conversion processing on the data from the A / D converter 23 or the data from the memory control unit 15. The image processing unit 24 performs predetermined calculation processing using the captured image data, and the system control unit 50 performs exposure control and distance measurement control based on the obtained calculation result.

  Thereby, AF (autofocus) processing, AE (automatic exposure) processing, and EF (flash pre-emission) processing of the TTL (through-the-lens) method are performed. The image processing unit 24 further performs predetermined calculation processing using the captured image data, and also performs TTL AWB (auto white balance) processing based on the obtained calculation result.

  Output data from the A / D converter 23 is directly written into the memory 32 via the image processing unit 24 and the memory control unit 15 or via the memory control unit 15. The memory 32 stores image data obtained by the imaging unit 22 and converted into digital data by the A / D converter 23 and image data to be displayed on the display unit 28. The memory 32 has a storage capacity sufficient to store a predetermined number of still images, a moving image and sound for a predetermined time.

  The memory 32 also serves as an image display memory (video memory). The D / A converter 13 converts the image display data stored in the memory 32 into an analog signal and supplies the analog signal to the display unit 28. Thus, the display image data written in the memory 32 is displayed on the display unit 28 via the D / A converter 13.

  The display unit 28 performs display according to the analog signal from the D / A converter 13 on a display such as an LCD. A digital signal once A / D converted by the A / D converter 23 and stored in the memory 32 is converted into an analog signal by the D / A converter 13 and sequentially transferred to the display unit 28 for display as an electronic viewfinder. It can function and display a through image.

  The nonvolatile memory 56 is an electrically erasable / recordable memory, and for example, an EEPROM or the like is used. The nonvolatile memory 56 stores constants, programs, and the like for operating the system control unit 50. A program here is a program for the system control part 50 to perform the various flowcharts mentioned later by this embodiment.

  The system control unit 50 controls the entire digital camera 100. By executing the program recorded in the non-volatile memory 56 described above, each process of the present embodiment to be described later is realized. A system memory 52 is a RAM. In the system memory 52, constants and variables for operation of the system control unit 50, programs read from the nonvolatile memory 56, and the like are expanded. The system control unit 50 also performs display control by controlling the memory 32, the D / A converter 13, the display unit 28, and the like.

  The system timer 53 is a time measuring unit that measures the time used for various controls and the time of a built-in clock. The mode switch 60, the shutter buttons 61 and 62, and the operation unit 70 are operation means for inputting various operation instructions to the system control unit 50.

  The mode switch 60 switches the operation mode of the system control unit 50 to any one of a still image recording mode, a moving image recording mode, a reproduction mode, and the like. Modes included in the still image recording mode include an auto shooting mode, an auto scene discrimination mode, a manual mode, various scene modes for shooting settings for each shooting scene, a program AE mode, a custom mode, and the like. The mode changeover switch 60 can directly switch to one of these modes included in the still image shooting mode.

  Alternatively, after switching to the still image shooting mode once with the mode switch 60, the mode may be switched to any one of these modes included in the still image shooting mode using another operation member. Similarly, the moving image shooting mode may include a plurality of modes. The shutter button 61 provided in the digital camera 100 is turned on when the shutter button 61 is half-pressed (shooting preparation instruction) during operation, and the first shutter switch signal SW1 is generated. In response to the first shutter switch signal SW1, operations such as AF (autofocus) processing, AE (automatic exposure) processing, AWB (auto white balance) processing, and EF (flash pre-emission) processing are started.

  When the operation of the shutter button 62 is completed, so-called full depression (shooting instruction), the second shutter switch signal SW2 is generated. In response to the second shutter switch signal SW2, the system control unit 50 starts a series of shooting processing operations from reading a signal from the imaging unit 22 to writing image data on the recording medium 200.

  Each operation member of the operation unit 70 is appropriately assigned a function for each scene by selecting and operating various function icons displayed on the display unit 28, and functions as various function buttons. Examples of the function buttons include an end button, a return button, an image advance button, a jump button, a narrowing button, and an attribute change button. For example, when a menu button is pressed, various setting menu screens are displayed on the display unit 28. The user can make various settings intuitively using the menu screen displayed on the display unit 28, and the four-way button and the SET button.

  In addition, as an operation member of the operation unit 70, there is a display switching button for switching between display and non-display of an operation button operated via the touch panel 71. By pressing the display switch button, the display and non-display of the operation button are performed. It is possible to switch.

  Along with the operation unit 70, a touch panel 71 capable of detecting contact with the display unit 28 is provided as an input unit of the digital camera. The touch panel 71 and the display unit 28 can be configured integrally. For example, the touch panel 71 is configured such that the light transmittance does not hinder the display of the display unit 28, and is attached to the upper layer of the display surface of the display unit 28. Then, the input coordinates on the touch panel 71 are associated with the display coordinates on the display unit 28. Thereby, it is possible to configure the GUI as if the user can directly operate the screen displayed on the display unit 28.

  The system control unit 50 can detect the following operations on the touch panel 71. Touching the touch panel with a finger or a pen (hereinafter referred to as touchdown). The touch panel 71 is touched with a finger or a pen (hereinafter referred to as touch-on).

These operations and the position coordinates of the finger or pen touching the touch panel 71 are notified to the system control unit 50 through the internal bus, and the system control unit 50 performs any operation on the touch panel 71 based on the notified information. It is determined whether or not.

  Regarding the move, the moving direction of the finger or pen moving on the touch panel 71 can also be determined for each vertical component / horizontal component on the touch panel 71 based on the change of the position coordinates. It is also assumed that a stroke is drawn when touch-up is performed on the touch panel 71 through a certain move from touch-down. The operation of drawing a stroke quickly is called a flick.

  The flick is an operation of quickly moving a certain distance while touching the finger on the touch panel 71 and releasing it, in other words, an operation of quickly tracing the touch panel 71 with a finger. If it is detected that the moving is performed at a predetermined speed or more over a predetermined distance, and a touch-up is detected as it is, it can be determined that a flick has been performed.

  In addition, when it is detected that the movement is performed at a predetermined distance or more and less than a predetermined speed, it is determined that the drag has been performed. The touch panel 71 uses any one of various types of touch panels 71 such as a resistive film method, a capacitance method, a surface acoustic wave method, an infrared method, an electromagnetic induction method, an image recognition method, and an optical sensor method. Also good.

  The remote terminal 73 is a terminal that enables control from an external device, and the system control unit 50 receives a command from the external device and controls the digital camera. When the system control unit 50 receives a command for switching display / non-display of the operation button from the remote terminal 73, the system control unit 50 performs switching control between display and non-display of the operation button.

  The power control unit 80 includes a battery detection circuit, a DC-DC converter, a switch circuit that switches a block to be energized, and the like, and detects whether or not a battery is installed, the type of battery, and the remaining battery level. Further, the power control unit 80 controls the DC-DC converter based on the detection result and an instruction from the system control unit 50, and supplies a necessary voltage to each unit including the recording medium 200 for a necessary period. The power supply control unit 80 includes a charging circuit, and supplies power to the power supply unit 30 based on an instruction from the system control unit 50 to charge the battery.

  The power supply unit 30 includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, an AC adapter, or the like. The recording medium I / F 18 is an interface with the recording medium 200 such as a memory card or a hard disk. The recording medium 200 is a recording medium such as a memory card for recording a captured image, and includes a semiconductor memory, a magnetic disk, or the like.

  FIG. 2 shows a flowchart of the moving image reproduction process in the present embodiment. This process is realized by developing a program recorded in the nonvolatile memory 56 in the system memory 52 and executing it by the system control unit 50.

  When one moving image to be reproduced is selected from the moving images recorded on the recording medium 200, the processing shown in the flowchart of FIG. 2 is started. For example, when a representative image of a moving image to be reproduced is touched down on the index screen on which representative images of a plurality of moving images are displayed in a multi-view, the moving image of the touched-down representative image is selected as a moving image to be reproduced, and the flowchart of FIG. Start processing.

  In S201, normal playback (constant speed playback) of the moving image is performed. A display example on the display unit 28 at this time is shown in FIG. A reproduced image 301 is displayed on the display unit 28. A reproduced image 301 is a moving image recorded on the recording medium 200 reproduced and displayed at a predetermined frame rate.

  Touch buttons 302 to 306 are displayed as display items so as to be superimposed on the reproduced image 301. When a touchdown is performed in each area of the touch buttons 302 to 306, a function assigned to the touch button is executed. The stop button 302 is a touch button for stopping the moving image being reproduced.

  The slow return button 303 is a touch button for performing reverse playback (hereinafter, slow return) of a selected moving image in slow motion (at a frame rate less than a constant speed). The slow feed button 304 is a touch button for sequentially reproducing the selected moving image in slow motion (in slow motion less than a constant speed) (hereinafter, slow feed).

  The fast reverse button 305 is a touch button for reversely reproducing (hereinafter referred to as “fast reverse”) the selected moving image at a speed equal to or higher than a constant speed (for example, a double speed, a quadruple speed, and a tenfold speed). The speed in the reverse direction may be increased by touching down the fast-rewind button 305 again in a state where the fast-rewind has already been performed.

  The fast-forward button 306 is a touch button for sequentially reproducing (hereinafter referred to as “fast-forward”) a selected moving image at a speed equal to or higher than a constant speed (for example, a double speed, a quadruple speed, and a tenfold speed). The forward speed may be increased by touching down the fast-forward button 306 again while fast-forwarding has already been performed. A playback method by touchdown on the slow reverse button 303, the slow forward button 304, the fast reverse button 305, and the fast forward button 306 is hereinafter referred to as special playback.

  The indicator 308 is an indicator that indicates the playback position of the current moving image over the entire time of the moving image. It is also possible to change the playback position to an arbitrary position by dragging the black knob. The date information 311 is obtained by superimposing the shooting date, which is the attribute information of the displayed moving image, on the reproduced image 301.

  The information display 312 displays various information such as the attribute information of the displayed moving image, the time code of the current playback position, and media information about the recording medium 200 superimposed on the playback image 301. The reproduction icon 321 is an icon indicating that the current operation state is during normal reproduction of a moving image. Hereinafter, the touch buttons 302 to 307 (307 will be described later), the indicator 308, the date information 311, and the information display 312 are collectively referred to as a button group.

Returning to the flowchart of FIG.
In S202, the erase timer is reset and countdown of the erase timer is started. The erase timer is a timer that measures the time until the button group is erased. As will be described later, when the erase timer reaches 0 during normal playback, the button group is deleted and only the playback image 301 is displayed.

  In S203, it is determined whether an information display button included in the operation unit 70 has been pressed. This information display button is not a touch button but a hardware operation member. If it is determined that the information display button has been pressed, the process proceeds to S204, and if not, the process proceeds to S207.

In S204, it is determined whether or not the button group is currently being displayed on the display unit 28. If the button group is not being displayed, the process proceeds to S205. If the button group is being displayed, the process proceeds to S206.
In S205, a button group is displayed. In the present embodiment, it is assumed that the button group displayed by pressing the information display button is not automatically deleted even when time elapses. Therefore, the erase timer is not started here. That is, if a display item is instructed to be displayed by an operation on a specific hardware operation member, control is performed so that the display is not hidden within a predetermined time even during normal playback.

In S206, the button group is deleted (not displayed) and only the reproduced image 301 is displayed. A display example at this time is shown in FIG. By hiding the button group, the reproduced image 301 can be suitably viewed in a state where nothing is superimposed on the reproduced image 301.
In S207, it is determined whether or not there is a touchdown on the touch panel 71 provided in the display unit 28. If it is determined that there is a touchdown, the process proceeds to S208. If not, the process proceeds to S221.

In S208, it is determined whether a button group is being displayed on the display unit 28 or not. If the button group is not being displayed, the process proceeds to S209. If the button group is being displayed, the process proceeds to S210.
In S209, a button group is displayed superimposed on the reproduced image displayed on the display unit 28. When the button group is displayed, the button group erase timer is reset and the countdown starts.

  That is, when the button group is not displayed on the display unit 28, when the display unit 28 (touch panel 71) is touched, the system control unit 50 performs reception processing for receiving an instruction to display, and the button group is displayed. In a touch displaying a button group, only a command for displaying the button group can be issued, and other operation instructions cannot be issued by the touch. In order to perform other operations such as pressing a touch button, it is necessary to touch down again while the button group is displayed after being touched up once.

  Also, if a normal playback is in progress after a predetermined time has elapsed since the button group was displayed in S209 by touchdown (when the erase timer reaches 0), the button group is automatically erased as described later. Disappears. When the process of S209 is completed, the process proceeds to S221.

  In S210, it is determined whether or not the touchdown touch position determined in S207 is outside the area of the touch operation member (not on the area of any touch operation member). If it is outside the area of the touch operation member, the process proceeds to S211; otherwise, the process proceeds to S212.

  In S211, the group of buttons displayed on the display unit 28 is erased and is not displayed, and only the reproduced image is displayed (FIG. 3B). That is, when the playback image is touched while the button group is displayed, the button group is deleted and only the playback image can be displayed.

  In S212, it is determined whether or not the touchdown position of the touchdown determined in S207 is on the fast reverse button 305 or the fast forward button 306. If it is determined that the touchdown position is on the fast reverse button 305 or the fast forward button 306, the process proceeds to S213, and if not, the process proceeds to S214.

  In S213, when the touch-down position is on the fast-rewind button 305, the displayed moving image is rewinded. When the touch-down position is on the fast-forward button 306, the displayed moving image is fast-forwarded. I do. Fast forward or fast reverse continues even after touch-up from the touch button until another playback method is instructed. Also, the erase timer is stopped. That is, during fast reverse and fast forward, the buttons are not automatically deleted after a predetermined time. Also, a play button 307 is displayed instead of the stop button 302.

  FIG. 3D shows a display example on the display unit 28 when fast-forwarding is performed. The playback button is a touch button for normally playing back a moving image. When the play button 307 is touched down, fast-forwarding is stopped and normal playback is performed. The fast-forward icon 323 is an icon indicating that the current operation state is fast-forwarding a moving image. The reproduced image 301 is displayed in a fast forward state.

  In S214, it is determined whether or not the touchdown position of the touchdown determined in S207 is on the slow return button 303 or the slow feed button 304. If the touchdown position is on the slow return button 303 or the slow feed button 304, the process proceeds to S205, and if not, the process proceeds to S216.

  In S215, when the touchdown position is on the slow return button 303, the displayed video is slowed back, and when the touchdown position is on the slow feed button 304, the displayed video is displayed. Perform slow feed. Slow forward or slow return continues after touch-up from the touch button until stop or another playback method is instructed. Also, the erase timer is stopped. That is, during the slow return and slow feed, the buttons are not automatically erased after a predetermined time. If the play button 307 is displayed, a stop button 302 is displayed instead.

  FIG. 3E shows a display example on the display unit 28 when performing slow feed. The slow feed icon 324 is an icon indicating that the current operation state is the slow feed of a moving image. The reproduced image 301 is displayed in a slow feed state.

In S216, it is determined whether or not the playback button 307 is displayed on the display unit 28. If the play button 307 is not displayed, that is, if the stop button 302 is displayed instead, the process proceeds to S217, and if the play button 307 is being displayed, the process proceeds to S219.
In S217, it is determined whether or not the touchdown position of the touchdown determined in S207 is on the stop button 302. If it is on the stop button 302, the process proceeds to S218, and if not, the process proceeds to S220.

In S218, the displayed moving image is stopped. If the erase timer is counting down, it is stopped (FIG. 3C).
In S219, it is determined whether or not the touchdown position of the touchdown determined in S216 is on the playback button 307. If it is on the playback button 307, the process proceeds to S201, and if not, the process proceeds to S220. In S201, normal playback of a moving image is performed as described above.

  In S220, other processing is performed according to the touchdown determined in S207. As other processing, for example, there is an operation of changing the playback position in accordance with the drag of the knob on the indicator 308.

In S221, it is determined whether or not the current operation state is normal reproduction of a moving image. If the normal reproduction is being performed, the process proceeds to S222, and if not, the process proceeds to S224.
In S222, it is determined whether or not the erase timer has finished counting down and the erase timer has become zero. If the erase timer is not 0, the process proceeds to S224, and if the erase timer is 0, the process proceeds to S223.

  In S223, the button group is deleted. In other words, during normal playback, the button group is automatically deleted when a predetermined time elapses after normal playback is started or the button group is displayed by touch, and only the playback image is displayed. A display example at this time is shown in FIG.

  In S224, it is determined whether or not there is an instruction to end the moving image playback screen. There are the following instructions for exiting the video playback screen. Transition to the index screen in the playback mode, an instruction to shift to another operation mode such as the shooting mode, an operation to remove the recording medium 200, and an operation to turn off the power. If there is no instruction to end the moving image playback screen, the process returns to S203 and is repeated. When there is an instruction to end the video playback screen, the video playback process ends.

  As described above, in this embodiment, whether or not to automatically delete various touch buttons and information display when reproducing a moving image is adaptively switched according to the reproduction state of the moving image. That is, during normal playback, it is automatically hidden after a predetermined time.

  On the other hand, if special reproduction is being performed, the display is not hidden until there is an erasure instruction (touch outside the touch operation member area) from the user. In this way, during normal playback that is assumed to be performed for viewing a moving image, the button group is hidden without the user performing a cumbersome operation, and the button group does not hinder the viewing of the playback image. You can watch the playback image.

  Also, when performing special playback such as fast-forward, fast-reverse, slow-forward, and slow-back, which is assumed to be in the process of searching for a desired playback position in the video, there is no erase instruction from the user As long as the button group remains displayed. Thus, the operation of searching for a desired reproduction position performed by combining operations on various touch buttons (performed while switching various special reproductions) can be performed with high operability. In this way, it is possible to adaptively switch between displaying with emphasis on appreciation and displaying with emphasis on operability according to the playback state of the moving image.

  In the above-described embodiment, the example in which whether or not to automatically hide the touch button displayed on the touch panel is switched according to the playback state of the moving image is described. However, the touch button is not a touch button displayed on the touch panel. However, the present invention is applicable. For example, an icon button (soft button) that uses a pointing device such as a mouse or a trackball instead of the touch panel described above, and performs a function by clicking the cursor and clicking it instead of a touch button. The invention is applicable. In that case, it is clear that the above-described touchdown can be replaced by clicking.

  Further, in the above-described embodiment, the case where the present invention is applied to the display control apparatus has been described as an example, but this is not limited to this example. Any display control device capable of displaying an operation panel for performing various operations and displaying operation buttons for performing touch input in a manner superimposed on the reproduced moving image can be applied. That is, the present invention can be applied to a personal computer, a PDA, a mobile phone terminal, a portable image viewer, a printer device including a display, a digital photo frame, a music player, a game machine, an electronic book reader, and the like.
