Description

  The present invention relates to a display control device and a control method for the display control device, and more particularly to a technique suitable for use so as not to easily cancel a dark place display.

  In recent years, as the sensitivity of imaging devices has increased, the number of shooting scenes has expanded, and it has been demanded that special scenes such as the starry sky that could not be easily shot up to now can be easily shot by a wide range of users. Astronomical photography requires setting the camera while observing the celestial object in the dark.

  Human vision has the characteristic of dark adaptation that can be perceived by faint light when in the dark for a long time. If you continue to observe astronomical objects in the dark, you will be able to adjust to darkness and see dark stars. In such a shooting scene, Patent Document 1 proposes a dark place display method in which blue and green gains are reduced from the camera setting display in order to maintain a dark-adapted state.

  The connector 112 is a connector between the connection cable 111 and the digital camera 100. The operation unit 70 is an operation unit including operation members such as various switches, buttons, and a touch panel for receiving various operations from the user. The controller wheel 73 is a rotatable operation member included in the operation unit 70.

  The power switch 72 is a push button for switching between power on and power off. The recording medium 200 is a recording medium such as a memory card or a hard disk. The recording medium slot 201 is a slot for storing the recording medium 200. The recording medium 200 stored in the recording medium slot 201 can communicate with the digital camera 100. A lid 202 is a lid of the recording medium slot 201.

FIG. 2 is a block diagram illustrating a configuration example of the digital camera 100 according to the present embodiment.
In FIG. 2, 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 functions and can perform live view display (live view display).

  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. Here, the program is a program for executing various flowcharts described later in the present 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 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 button 61, and the operation unit 70 are operation means for inputting various operation instructions to the system control unit 50.

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 first shutter switch 62 is turned on when the shutter button 61 provided in the digital camera 100 is being operated, so-called half-press (shooting preparation instruction), and generates a first shutter switch signal SW1. 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.

  The second shutter switch 64 is turned ON when the operation of the shutter button 61 is completed, that is, when it is fully pressed (shooting instruction), and generates a second shutter switch signal SW2. 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.

  The controller wheel 73 is a rotatable operation member included in the operation unit 70, and is used when a selection item is instructed together with a direction button. When the controller wheel 73 is rotated, an electrical pulse signal is generated according to the operation amount, and the system control unit 50 controls each unit of the digital camera 100 based on the pulse signal. From this pulse signal, it is possible to determine the angle at which the controller wheel 73 is rotated, how many rotations, and the like.

  The controller wheel 73 may be any operation member that can detect a rotation operation. For example, it may be a dial operation member that generates a pulse signal by rotating the controller wheel 73 itself according to the rotation operation of the user. Further, an operation member made of a touch sensor may detect the rotation operation of the user's finger on the controller wheel 73 without rotating the controller wheel 73 itself (so-called touch wheel).

  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 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.

  The communication unit 54 is connected by radio or a priority cable, and transmits and receives video signals and audio signals. The communication unit 54 can be connected to a wireless local area network (LAN) or the Internet. The communication unit 54 can transmit an image captured by the imaging unit 22 (including a through image) and an image recorded on the recording medium 200, and can receive image data and other various types of information from an external device. it can.

  The posture detection unit 55 detects the posture of the digital camera 100 with respect to the direction of gravity. Based on the attitude detected by the attitude detection unit 55, it is determined whether the image shot by the imaging unit 22 is an image shot with the digital camera 100 held horizontally or an image shot with the image held vertically. It can be determined.

  The system control unit 50 can add orientation information corresponding to the posture detected by the posture detection unit 55 to the image file of the image picked up by the image pickup unit 22, or rotate and record the image. is there. As the attitude detection unit 55, an acceleration sensor, a gyro sensor, or the like can be used.

  The digital camera 100 can be switched between at least a playback mode for playing back an image and a shooting mode for shooting. The shooting mode includes an auto mode, a manual mode, and a plurality of scene-specific shooting modes. Has a mode. The auto mode is a mode in which various parameters of the camera are automatically determined by a program incorporated in the digital camera 100 based on the measured exposure value.

  The manual mode is a mode in which the user can freely change various parameters of the camera. The scene-specific shooting mode is a shooting mode realized by combining a shutter speed and an aperture value, a strobe light emission state, a sensitivity setting, a white balance (WB) setting, and the like suitable for each shooting scene. The digital camera 100 has, for example, the following scene-specific shooting modes (1) to (13). However, it is not limited to these scene-specific shooting modes.

The photographer can set the digital camera 100 to a desired shooting mode from the shooting mode selection menu and perform shooting.

  FIG. 3 shows a flowchart for explaining the overall dark place display process according to this embodiment. This process is realized by the program recorded in the nonvolatile memory 56 being expanded in the system memory 52 and executed by the system control unit 50. The system control unit 50 performs control so as to cancel the dark place display when a predetermined condition is satisfied.

Starts when the digital camera is activated and the shooting mode is selected.
When the process is started, in S300, the system control unit determines whether mode switching has been performed. When the mode is switched, the process proceeds to S301. If the mode is not switched, the process jumps to S307.

In S301, the selected shooting mode is switched, and the process proceeds to S302.
In S302, it is determined whether or not the currently selected shooting mode is compatible with dark place display processing. If it is determined that the currently selected shooting mode is compatible with dark place display processing, the process proceeds to S303, and dark place display is performed. If it is determined that they are not compatible, the process proceeds to S305.

In the present embodiment, it is assumed that the following shooting modes are shooting modes corresponding to dark place display processing.
(2) Night view shooting mode, (3) Fireworks shooting mode, (8) Night & snap shooting mode, (10) Starry sky snap mode, (11) Starry night view mode, (12) Starry sky trail mode, (13) Starry sky interval movie mode.

  In the shooting mode corresponding to the dark place display process, the dark place display can be set to ON from the menu setting, and the display in the dark place display mode can be performed. In a shooting mode that does not support dark place display processing, there is no dark place display menu item or it is grayed out so that it cannot be selected and dark place display cannot be turned on. That is, dark place display cannot be performed in a shooting mode that does not support dark place display processing.

In S303, the system control unit 50 determines whether or not the setting menu has been opened and a dark place display setting on / off switching operation has been performed. If the dark place display switching operation has been performed, the process proceeds to S304, and if not, the process proceeds to S307.
In S304, the dark place display is switched on / off according to the user operation. When the dark place display is set from OFF to ON, the dark place display is performed. In the dark place display, a process of changing the color of the display item from a normal color when dark place display is OFF to a dark place display color is performed.

FIG. 5A shows a display example during dark place display.
FIG. 5A is a diagram for explaining display contents of the display unit 28 disposed on the back surface of the digital camera 100 during dark place display. On the display unit 28, the shooting information 501 is displayed in a state where the OSD (display item) is subjected to color conversion suitable for a dark place, superimposed on the through image 500. Since the through image 500 itself is assumed not to be bright because it is in a dark place, the through image 500 itself is not subjected to color conversion for dark places, and normal display is performed.

  In photographing in a dark environment such as astronomical observation, it is known that the photographer adapts his eyes to a dark environment (dark adaptation). Since dark adaptation is easily solved by light having a wavelength close to blue, in order to maintain dark adaptation, a display that reduces light having a wavelength near blue in visible light is effective. That is, it is known that the dark adaptation can be made difficult to be solved by performing display in which the B component is suppressed among the RGB components as the color component (display in which blue is suppressed).

  In this embodiment, by turning on the dark place display setting, only the B component or the B component and the G component are reduced on the display unit 28, and a dark place display such as a dull orange or brown color is performed. In FIG. 5A and FIG. 5B, the shooting information 501 is shaded to indicate the display as described above. As a result, a color display suitable for a dark place where the user's visual dark adaptation is easily maintained is performed.

  In S305, the system control unit 50 determines whether the dark place is currently displayed. If the dark place is being displayed, the process proceeds to S306. If not, the process proceeds to S307. . The dark place display cancellation control process in S306 will be described later.

  In S307, it is determined whether or not there has been a process end event (such as power OFF). If the process has not ended, the process returns to S300, and if it is determined that the process has ended, the process ends.

FIG. 4 is a flowchart for explaining the details of the procedure of the dark place display canceling control process in S306 of FIG. 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 the dark place display release control process is entered, in S400, the system control unit 50 is in a mode that does not support dark place display and is in the dark place display, and therefore the guidance that cancels the dark place display. The dark place display release warning is displayed.

FIG. 5B shows a display example of the dark place display release warning display.
FIG. 5B is a diagram for explaining the display contents of the display unit 28 arranged on the back surface of the digital camera 100 displaying the dark place display cancellation warning. On the display unit 28, a dark place display cancellation warning 511 is displayed so as to be superimposed on the through image 500. At this time, the dark place display continues in the ON state.

  In S401, it is determined whether or not the shooting mode has been switched. If it is determined that the mode has not been switched, the process proceeds to S402. If it is determined that the mode has been switched, the dark place display cancellation control process is terminated to determine again whether the mode is a dark place display compatible mode. To do. As a result, when switched to a shooting mode that supports dark place display, even if the shooting mode that is not compatible with dark place display is used, the dark place display is supported without canceling the dark place display. This means that it was possible to switch to another shooting mode.

  For example, when the fireworks shooting mode corresponding to the dark place display is switched to the sports shooting mode not corresponding to the dark place display, and then immediately switched to the starry sky snap mode (without being Yes in S402 and S403 described later). . It is possible to shift to shooting in the starry sky snap mode while maintaining dark adaptation without canceling the dark place display.

  Thus, for example, in the shooting mode switching dial or the order of switching of the shooting mode with toggle, the mode that does not support the dark place display between the first mode and the second mode corresponding to the dark place display. When is caught. That is, even if it is not possible to switch from the first mode corresponding to the direct dark place display to the second mode, if the switching operation is performed quickly, the dark mode display is not canceled and the other modes are released from the first mode. To switch to the second mode. Or, after switching from the first mode corresponding to the dark place display to the mode not corresponding to the dark place display, even if the user returns to the original first mode quickly, the dark place display is continued without being canceled. can do.

  In S402, the system control unit 50 determines whether or not an operation member other than the operation member for mode switching has been operated, and if it is determined that an operation member other than the operation member for mode switching has been operated, S404 Proceed to, and turn off the dark display. When an operation member other than the operation member for mode switching is operated, it means that the operation in the current photographing mode just switched is performed.

  In other words, the current shooting mode is not in the middle of switching to another shooting mode, but it is assumed that the user is willing to shoot in the current shooting mode, so confirm the mode and cancel the dark display. Can be assumed. Although an example of determining whether or not an operation member other than the operation member for mode switching has been operated has been described, a specific operation member (for example, a set button) for instructing confirmation of the current mode is operated. It may be determined whether or not.

If it is determined in S402 that no operation member other than the operation member for mode switching is operated, the process proceeds to S403.
In S403, the system control unit 50 determines an elapsed time after displaying the dark place display release warning display, and when a predetermined time (for example, about 3 seconds) has elapsed, the process proceeds to S404, and the predetermined time If it is determined that the period has not elapsed, the process returns to S401.
In S404, the system control unit 50 hides the dark place display cancellation warning display and sets the dark place display to OFF.

FIG. 5C shows a display example after canceling the dark place display.
FIG. 5C is a diagram for explaining the display contents of the display unit 28 arranged on the back surface of the digital camera 100 from which the dark place display is canceled. On the display unit 28, the dark place display is canceled and an information display 521 which is an OSD display of a normal color component (that is, the B component is not reduced) is displayed.

  As described above, according to the present embodiment, the dark place display is turned off even when the display is switched to the shooting mode that is not intended and does not support the dark place display during the dark place display. Can be confirmed in advance. Thereby, the display part becomes bright because the dark place display is turned off, the eyes are brightly adapted, and it is possible to prevent the problem that it takes time to darkly adapt again. In the above-described embodiment, an example in which a warning is displayed by switching between shooting modes has been described. However, a transition to a playback mode or a transition to another mode may be performed.

  In the present embodiment, an example in which the dark place display setting is turned on / off by a user operation in the shooting mode corresponding to the dark place display process has been described. However, the dark place display setting may be automatically switched by detecting the surrounding environment. Good. For example, if it is determined that the through image being shot is low in brightness and is in a dark place, the dark place display setting is automatically turned on, and if the through image is bright and is determined not to be in a dark place The dark place display setting may be automatically turned off.

(Second Embodiment)
In addition to or in addition to the above-described embodiment, there is a shooting mode that does not support the dark place display between the shooting modes that correspond to the dark place display. You may make it be the arrangement order which is not pinched. That is, the operation modes corresponding to the dark place display are set so that neither the previous operation mode nor the next order of the operation mode corresponding to the dark place display becomes the operation mode not compatible with the dark place display. Adjacent order.

  In this way, when switching from the first shooting mode corresponding to dark place display to the second shooting mode corresponding to dark place display, it is necessary to pass through a shooting mode that does not support dark place display. Can be switched without canceling the dark place display. In this case, the dark place display may be canceled immediately when switching to a shooting mode that does not support the dark place display without performing the processing shown in FIG.

In the shooting mode of the present embodiment, switching is performed sequentially in a predetermined order. For example, the switching order of the shooting modes is set as follows (the arrangement order on the mode dial is as follows). The order of switching is described in <>.
<1> (1) Water shooting mode (beach mode).
<2> (4) Underwater shooting mode.
<3> (5) Sunset shooting mode.
