  FIG. 3 is a block diagram showing an example of the configuration of the camera shown in FIG.

  In FIG. 3, the camera 100 includes a photographic lens unit (hereinafter simply referred to as a photographic lens) 103, and the photographic lens 103 includes at least a zoom lens and a focus lens.

  A shutter 101 having an aperture function is disposed at the rear stage of the photographing lens 103. On the rear side of the shutter 101, an imaging unit 22 having an imaging element such as a CCD or a CMOS element that converts an optical image (subject image) into an electrical signal (analog signal) is disposed. The analog signal that is the output of the imaging unit 22 is converted into a digital signal (image data) by the A / D converter 23.

  A barrier 102 is arranged on the front side of the photographing lens 103, and this barrier 102 covers the photographing system such as the photographing lens 103, the shutter 101, and the image pickup unit 22 to prevent dirt and damage. It is.

  The image processing unit 24 receives the image data that is the output of the A / D converter 23 or the image data from the memory control unit 15 and performs a resizing process such as predetermined pixel interpolation and reduction and a color conversion process. Further, the image processing unit 24 performs a predetermined calculation process using image data obtained as a result of imaging.

  The system control unit 50 performs exposure control and distance measurement control based on the calculation result. As a result, TTL (through the lens) AF (autofocus) processing, AE (automatic exposure) processing, and EF (flash pre-emission) processing are performed.

  Further, the image processing unit 24 performs predetermined calculation processing using image data obtained as a result of imaging, and performs TTL AWB (auto white balance) processing based on the calculation result.

  The image data output from the A / D converter 23 is written into the memory 32 via the image processing unit 24 and the memory control unit 15 or directly via the memory control unit 15. The memory 32 has a sufficient storage capacity for storing a predetermined number of still images or moving images and sound for a predetermined time.

  The illustrated memory 32 also serves as an image display memory (video memory). The display image data written in the memory 32 is given to the display unit 28 via the D / A converter 13 and is displayed as an image. Is displayed.

  The display unit 28 is, for example, an LCD. Further, if the image data stored in the memory 32 is D / A converted by the D / A converter 13 and sequentially transferred and displayed on the display unit 28, the display unit 28 functions as an electronic viewfinder, and the through image is displayed. Display (live view image display) can be performed.

  As described above, the accessory shoe 75 is connected to the camera external device. Here, the camera external device is, for example, the EVF 122 shown in FIG. The system control unit 50 controls the EVF 122 via the accessory shoe 75.

  In other words, as described with reference to FIG. 2, when the EVF 122 is connected to the accessory shoe 75, the system control unit 50 sequentially displays image data via the accessory shoe 75 and displays a through image on the EVF 122.

  The system control unit 50 controls the entire camera 100. The nonvolatile memory 56 is an electrically erasable / recordable memory, and for example, an EEPROM is used. The nonvolatile memory 56 stores constants, variables, programs, and the like for operating the system control unit 50. This program includes a program for executing various flowcharts to be described later.

  The system memory 52 is, for example, a RAM, and the system control unit 50 reads operation constants, variables, programs, and the like from the nonvolatile memory 56 and develops them in the system memory 52.

  The image data written in the memory 32 is filed in the system control unit 50 and recorded on the recording medium 200 via the interface (I / F) 18. In addition, the system control unit performs display control by controlling the memory 32, the D / A converter 13, the display unit 28, and the like.

  A system timer 53 is connected to the system control unit 50, and the system timer 52 measures the time used for various controls by the system control unit 50 and gives it to the system control unit 50.

  The above-described mode changeover switch 60 is a switch for switching 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, for example.

  The still image recording mode includes, for example, 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, and a custom mode. If the mode switch 60 is used, it is possible to directly switch to any of these modes.

  In addition, after the mode changeover switch 60 temporarily switches to the still image recording mode, the operation unit 70 may be used to switch to any of the above modes. Similarly, the moving image recording mode includes a plurality of modes.

  When the shutter button 61 is in the middle of operation (half-pressed: photographing preparation instruction), a first shutter switch (not shown) is turned on, and the first shutter switch signal SW1 is given to the system control unit 50.

  Accordingly, the system control unit 50 starts operations such as AF (autofocus) processing, AE (automatic exposure) processing, AWB (auto white balance) processing, and EF (flash preflash) processing.

  When the operation of the shutter button 61 is completed (fully pressed), a second shutter switch (not shown) is turned on and a second shutter switch signal SW2 is given to the system control unit 50.

  Accordingly, the system control unit 50 starts a series of imaging processing operations from reading the signal of the imaging unit 22 to writing the image data on the recording medium 200.

  When various function icons displayed on the display unit 28 are selected and operated, functions are appropriately assigned to each scene, and the operation unit 70 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.

  When the menu button is operated on the operation unit 70, the system control unit 50 displays a menu screen for performing various settings on the display unit 28. The user can intuitively make various settings using the four-way key up / down / left / right and the SET button by looking at the menu screen displayed on the display unit 28.

  The controller wheel 73 shown in FIG. 1 is used when a selection item is designated together with a direction button. When the controller wheel 73 is rotated, an electrical pulse signal corresponding to the amount of operation is generated. The system control unit 50 controls the camera 100 based on the pulse signal. The system control unit 50 can know the angle at which the controller wheel 73 is rotated by the pulse signal and the number of rotations thereof.

  The controller wheel 73 may be any operation member that can detect a rotation operation. For example, the controller wheel 73 may be a dial operation member that generates a pulse signal in response to a user's rotation operation.

  Further, the controller wheel 73 may be an operation member made of a touch sensor without rotating, and may detect a rotation operation of a user's finger (so-called touch wheel).

  The power control unit 80 (power supply means) includes a battery detection circuit, a DC-DC converter, and a switch circuit that switches a block to be energized. Then, the power control unit 80 detects the presence / absence of a battery, the type of battery, and the remaining battery level. Further, the power supply control unit 80 controls the DC-DC converter based on the detection result and the instruction from the system control unit 50, and applies a predetermined voltage to each part of the camera 100 including the recording medium 200 for a necessary period. Supply.

  Here, the power supply control unit 80 is connected to the EVF 122 connected to the accessory shoe 75 via a power supply connector (not shown) provided in the accessory shoe 75 under the control of the system control unit 50. Power is supplied from 30.

  The power supply unit 30 is connected to the power supply control unit 80. The battery unit 30 includes a primary battery such as an alkaline battery or a lithium battery, or a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, and an AC adapter.

  The recording medium I / F 18 is an interface with a recording medium 200 such as a memory card or a hard disk, and image data obtained as a result of photographing is recorded on the recording medium 200. The recording medium 200 is composed of, for example, a semiconductor memory or a magnetic disk.

  A communication unit 54 is connected to the system control unit 50, and the communication unit 54 is connected to an external device (not shown) by a wireless or priority cable (for example, the connection cable 111 shown in FIG. 1). The communication unit 54 transmits / receives a video signal (that is, image data) and an audio signal to / from an external device under the control of the system control unit 50.

  The communication unit 54 can be connected to a wireless LAN (Local Area Network) or the Internet. The communication unit 54 can transmit image data (including a through image) obtained as a result of imaging by the imaging unit 22 and image data recorded on the recording medium 200 to an external device. The communication unit 54 can receive image data and other various types of information from an external device.

  A posture detection unit 55 is connected to the system control unit 50, and the posture detection unit 55 detects the posture of the camera 100 with respect to the direction of gravity and sends the posture detection result to the system control unit 50. The system control unit 50 is an image obtained as a result of imaging by the imaging unit 22 based on the attitude detection result, or an image obtained by holding the camera 100 sideways or taken vertically. Is determined.

  The system control unit 50 adds orientation information indicating the orientation of the camera 100 determined as described above to the image file. Further, the system control unit 50 can rotate the image according to the orientation information and record it on the recording medium 200.

  As the posture detection unit 55, for example, an acceleration sensor or a gyro sensor is used.

  FIG. 4 is a diagram for explaining an example of photographing processing in the camera 100 shown in FIG.

  4 is performed under the control of the system control unit 50. That is, the system control unit 50 performs the processing according to the flowchart shown in FIG. 4 by developing the program stored in the nonvolatile memory 56 in the system memory 52 and executing the program.

  When the shooting mode is set by the operation unit 70, the system control unit 50 enters a shooting standby state. At this time, when the user depresses a menu button provided in the operation unit 70, the system control unit 50 displays a menu screen on the display unit 28, for example.

  The user can set whether to switch the display destination (that is, the EVF 122 and the display unit 28) manually or automatically from the setting menu item related to the display destination on the menu screen. Then, the system control unit 50 records the set switching information in the nonvolatile memory 56.

  Subsequently, the system control unit 50 refers to the switching information recorded in the nonvolatile memory 56 and determines whether or not the through image display destination is set to manual (manual) in the setting menu. To do. That is, the system control unit 50 determines whether the display destination switching is manual switching (manual switching mode) (S401).

  If the display destination is switched to the manual switching mode (YES in S401), the system control unit 50 determines whether or not the display destination switching button 124 provided in the EVF 122 is pressed (S402).

  When the display destination switching button 124 is pressed (YES in S402), the system control unit 50 determines whether to switch the display destination to the external EVF 122 or the display unit 28 according to the pressing of the display destination switching button 124. judge. Then, the system control unit 50 determines whether or not the display destination is switched to the EVF 122 (S403).

  Here, when the display destination is the EVF 122 before the display destination switching button 124 is pressed, the system control unit 50 switches the display destination to the display unit 28. On the other hand, if the display destination is the display unit 28 before the display destination switching button 124 is pressed, the system control unit 50 switches the display destination to the EVF 122.

  If the display destination is not switched to EVF 122 (NO in S403), that is, if the display destination is display unit 28, system control unit 50 hides EVF 122 and stops energization of eye sensor 123 (eye sensor). Off). Then, the system control unit 50 performs live view display with the display unit 28 in the display state (S404). Thereafter, the system control unit 50 proceeds to the process of S412 described later.

  In the process of S404, the system control unit 50 controls the power supply control unit 80 so that power is not supplied to the display unit (that is, the eyepiece unit 125) and the eye sensor 124 of the EVF 122.

  When the display destination is switched to EVF 122 (YES in S403), that is, when the display destination is EVF 122, system control unit 50 performs live view display on EVF 122 and activates eyepiece sensor 123 (that is, eyepiece sensor 123 operates). Supply power). Then, the system control unit 50 puts the display unit 28 into a non-display state (S405).

  Subsequently, the system control unit 50 determines whether or not the EVF 122 is in contact (that is, in an eyepiece state) based on the detection result of the eyepiece sensor 123 (S406). If the EVF 122 is in the non-eyepiece state (NO in S406), has the system control unit 50 elapsed a predetermined time (for example, 6 seconds) after switching the display destination to the EVF 122 by pressing the display destination switching button 124? It is determined whether or not (S407).

  If a predetermined time has not elapsed since the display destination was switched to EVF 122 (NO in S407), system control unit 50 stands by in a state where live view display is performed on EVF 122.

  On the other hand, when a predetermined time elapses after the display destination is switched to EVF 122 (YES in S407), system control unit 50 turns off EVF 122 with the eye sensor 123 turned on (not displayed). : S408). Thereafter, the system control unit 50 proceeds to the process of S412 described later.

  Here, if the eyepiece is not detected even after a predetermined time has elapsed after the EVF 122 is in the display state, the system control unit 50 sets the EVF 122 in the non-display state while turning the eyepiece sensor 123 on. That is, if an eyepiece is not detected, the system control unit 50 displays the EVF 122 for a predetermined time.

  In this way, live view display is performed on the EVF 122 for a predetermined time even in the non-eyepiece state immediately after the user depresses the display destination switching button 124 and switches the display destination to the EVF 122.

  Thus, for example, even when the user depresses the display destination switching button 124 in a non-eyepiece state, the EVF 122 is turned on (because the display state is entered), so that the user responds to the user operation with the display destination. Can be confirmed.

  In this case, since the display unit 28 is turned off (non-display state), both the EVF 122 and the display unit 28 are in a non-display state when a predetermined time has elapsed. As a result, it is possible to avoid a situation in which unnecessary power is consumed in the EVF 122 after a predetermined time elapses when the eyepiece is not in contact.

  If the EVF 122 is in the eyepiece state in S406 (YES in S406), the system control unit 50 proceeds to the process of S412 described later. If the display destination switching button 124 is not pressed in S402 (NO in S402), the system control unit 50 proceeds to the process of S412 described later.

  If the display destination switching is automatic switching (automatic switching mode) in S401 (NO in S401), the system control unit 50 determines whether or not the EVF 122 is in contact with the eye based on the detection result acquired from the eye sensor 123. Is determined (S409).

  If EVF 122 is in the non-eyepiece state (NO in S409), system control unit 50 places EVF 122 in the non-display state (turns off) and displays live view on display unit 28 (S410).

  At this time, since the display destination switching setting is automatic (automatic), the system control unit 50 turns the eyepiece sensor 123 on (on) and continues the eyepiece detection operation.

  On the other hand, if EVF 122 is in the eyepiece state (YES in S409), system control unit 50 performs live view display on EVF 122, and hides display unit 28 (S411).

  At this time, since the display destination switching setting is automatic (automatic), the system control unit 50 turns on the eyepiece sensor 123 and continues the eyepiece detection operation.

  Following the processing of S410 or S411, the system control unit 50 determines whether or not the shutter button 61 is half-pressed and the first shutter switch is turned on (S412). When the shutter button 61 is half-pressed (YES in S412), the system control unit 50 performs shooting preparation processing (for example, AE / AF processing) (S413).

  Thereafter, the system control unit 50 determines whether or not the shutter button 61 is fully pressed and the second shutter switch is turned on (S414). When the shutter button 61 is fully pressed (YES in S414), the system control unit 50 performs shooting (S415). That is, the system control unit 50 captures an image in the image capturing unit 22 to generate an image file, and records the image file in the recording medium 200. Then, the system control unit 50 returns to the process of S401 and determines whether or not the display destination switching is manual.

  If the shutter button 61 has not been fully pressed (NO in S414), the system control unit 50 determines whether or not the shutter button 61 is half-pressed (S416). If the shutter button 61 is half-pressed (YES in S416), the system control unit 50 returns to the process of S414 and determines whether or not the shutter button 61 has been fully pressed.

  On the other hand, if the shutter button 61 is not half-pressed (NO in S416), the system control unit 50 returns to the process of S401 and determines whether the display destination switching is manual.

  As described above, in the process of S404, the system control unit 50 controls the power supply control unit 80 so as not to supply power to the display unit of the EVF 122 and the eye sensor 123. Here, since the switching of the display destination is manual and the display destination is not switched to the EVF 122, even if the EVF 122 is touched, the EVF 122 may be hidden.

  In this manner, in the process of S404, power is not supplied to the eye sensor 123, so that waste of power consumption can be reliably suppressed.

  On the other hand, even if the switching of the display destination is manual, when the display destination is switched to the EVF 122, power is supplied to the eye sensor 123 to drive the eye sensor 123. Here, even when the display destination is the EVF 122, in a state where the user is not eyed (a state where the user is not looking at the EVF 122), the EVF 122 is turned off to reduce power consumption.

  That is, in the process of S408, the display destination is switched to the EVF 122 rather than saving power by cutting off the power supply to the eye sensor 123. Therefore, the eye sensor 123 is energized in consideration of the user's eye contact. Thus, when the EVF 122 is turned off when a predetermined time elapses, the power saving effect is higher.

  As described above, in the embodiment of the present invention, when the display destination of the through image is selectively switched between the EVF 122 and the display unit 28, the power consumption can be effectively suppressed.

  In the above-described embodiment, an example using an external EVF has been described, but the same applies to an internal EVF (that is, an EVF and an eye sensor integrated with the camera 100) instead of the external EVF. be able to.

  In the example shown in FIG. 3, at least the power supply unit 30, the power supply control unit 80, the system control unit 50, the display unit 28, and the accessory shoe 75 constitute a display control device.

  Note that the control by the system control unit 50 may be performed by one piece of hardware, or the entire apparatus may be controlled by a plurality of pieces of hardware sharing the processing.
