FIG.

(First embodiment)
FIG. 1 is a cross-sectional view schematically showing the configuration of the camera system according to the first embodiment of the present invention. The digital camera 1 includes a camera body 100 and an interchangeable lens 200 that can be attached to and detached from the camera body 100.

  The camera body 100 has a so-called bayonet lens mount. When the mount portion of the interchangeable lens 200 is fitted and fixed to the mount portion of the camera body 100, the plurality of electrical contacts 202 provided in the vicinity of the mount portion of the interchangeable lens 200 become the plurality of electric contacts provided in the vicinity of the mount portion of the camera body 100. It is electrically connected to the contact 102.

  The interchangeable lens 200 has an imaging optical system that receives a light beam from a subject and forms a subject image on an imaging surface. This imaging optical system includes a plurality of lenses 203, 204, 205 and a diaphragm 206. Among these, the lens 204 is a focusing lens that can move in a direction along the optical axis O. The camera body 100 includes an image sensor 104 that captures a subject image formed by the imaging optical system, converts the subject image into an electrical signal, and outputs the electrical signal. The image sensor 104 is a solid-state image sensor such as a CCD or CMOS. Although omitted in FIG. 1, an infrared cut filter for cutting infrared light, an optical low-pass filter for preventing image aliasing noise, and the like are arranged on the imaging surface of the image sensor 104. Yes.

  A quick return mirror 103 is disposed in the camera body 100. The quick return mirror 103 reflects a subject light from the imaging optical system toward a viewfinder screen 107 disposed on the upper part of the camera body 100 (a position indicated by a solid line in FIG. 1), and a quick return mirror 103 from the imaging optical system. It is configured to be movable between a retracted position outside the optical path of the subject light (a position indicated by a broken line in FIG. 1). The quick return mirror 103 is moved to the reflection position when using the optical viewfinder, and is moved to the retracted position when using the live view function. The viewfinder screen 107 is arranged at a position conjugate with the image sensor 104 with respect to the quick return mirror 103 at the reflection position.

  When the quick return mirror 103 is in the reflection position, the subject light reflected by the reflecting surface of the quick return mirror 103 is transmitted through the finder screen 107 and introduced into the pentaprism 108 (pentagonal roof prism), and emitted toward the eyepiece 110. Is done. The photographer can visually recognize the subject image through the eyepiece 110.

  Near the center of the quick return mirror 103 (near the optical axis X of the optical system) is a half mirror, and part of the subject light passes through this half mirror. This transmitted light beam is reflected by the sub-mirror 105 provided on the back surface of the quick return mirror 103 and enters the focus detection device 106 provided at the lower part of the camera body 100. The focus detection device 106 executes focus detection processing such as a well-known pupil division type phase difference detection method and detects the focus adjustment state of the imaging optical system.

  When the quick return mirror 103 and the sub mirror 105 move to the retracted position, the subject light transmitted through the imaging optical system is introduced into the image sensor 104. At this time, the image sensor 104 can capture a subject image formed on the imaging surface.

  The interchangeable lens 200 includes a lens control device 209 that controls each part of the interchangeable lens 200. The camera body 100 includes a body control device 109 that controls each part of the camera body 100. The lens control device 209 and the body control device 109 perform bidirectional data communication by exchanging electrical signals via a plurality of electrical contacts 102 and 202 provided on the mount portions on the camera body side and the interchangeable lens side, respectively. It can be carried out.

  The interchangeable lens 200 includes a lens driving unit 207 that drives the focusing lens 204 in a direction along the optical axis O. The lens driving unit 207 includes an actuator (not shown) (for example, a stepping motor), and drives the focusing lens 204 according to the driving speed, the driving amount, and the driving direction given from the lens control device 209.

  The camera body 100 includes an aperture driving unit 111 having an actuator (not shown). The diaphragm driving unit 111 transmits the driving force by the actuator to the diaphragm 206 in the interchangeable lens, and drives the diaphragm 206.

  On the back surface (the surface on which the viewfinder is provided) of the camera body 100, a back monitor 112 configured by, for example, a liquid crystal panel or the like is provided. The body control device 109 performs control for displaying a photographed image and various setting screens on the rear monitor 112. On the display surface of the rear monitor 112, for example, a capacitive touch panel 113 is laminated. The touch panel 113 detects the position where the user's finger or the like is in contact, and notifies the body control device 109 of the detected position.

(Description of external monitor)
FIG. 2 is a block diagram showing a connection relationship between the body control device 109 and various display devices. The body control device 109 is electrically connected to the rear monitor 112 described with reference to FIG. The body control device 109 can output a video signal to the rear monitor 112 and display various information (for example, a through image, a photographed image, and a setting menu) on the rear monitor 112.

  The body control device 109 can be connected to various external monitors 300 via the connector 121, the electrical contact group 122, and the wireless communication module 123.

  More specifically, the external monitor 300 includes a first external monitor 301 that can be connected to the camera body 100 via the connector 121 and a second external monitor 302 that can be connected to the camera body 100 via the electrical contact group 122. There are three types of the third external monitor 303 that can be connected to the camera body 100 via the wireless communication module 123. In the following description, the first external monitor 301, the second external monitor 302, and the third external monitor 303 are collectively referred to as the external monitor 300. The digital camera 1 can be used without connecting the external monitor 300, can be used with only one external monitor 300 connected, or can be used with two or more external monitors 300 connected. it can.

  The body control device 109 can perform bidirectional data communication with the external monitor 300 connected to the interface via the connector 121, the electrical contact group 122, and the wireless communication module 123. For example, the body control device 109 can transmit a video signal by this data communication and display various information (for example, a through image, a photographed image, a setting menu) on the external monitor 300.

  The connector 121 is a coaxial connector or a D-sub connector, for example, and is installed on the side surface of the camera body 100. The first external monitor 301 can be electrically connected to the connector 121 by the cable 10 having a receptacle having a shape corresponding to the connector 121. When the first external monitor 301 is connected, power supply from the camera body 100 to the first external monitor 301 via the connector 121 and the cable 10 is started.

  The electrical contact group 122 is provided on an accessory shoe located at the top of the camera body 100. When the second external monitor 302 is attached to the accessory shoe, the electrical contact group 122 is electrically connected to the electrical contact group 12 provided on the second external monitor 302. When the second external monitor 302 is connected, power supply from the camera body 100 to the second external monitor 302 via the electrical contact group 122 and the electrical contact group 12 is started.

  The wireless communication module 123 is an electronic circuit that can perform wireless communication with the wireless communication module 13 provided in the third external monitor 303 by, for example, light or radio waves. For example, when the body control device 109 outputs a video signal to the wireless communication module 123, the wireless communication module 123 modulates the video signal into light, a radio wave, or the like, and transmits it to the wireless communication module 13 of the third external monitor 303. The wireless communication module 13 receives it, demodulates it to the original video signal, and causes the third external monitor 303 to display information based on the video signal. The third external monitor 303 has a built-in power supply source such as a battery and operates without receiving power supply from the camera body 100.

  FIG. 3 is a diagram showing an example of the external appearance of the external monitor. 3A illustrates the first external monitor 301, FIG. 3B illustrates the second external monitor 302, and FIG. 3C illustrates the third external monitor 303.

  As shown in FIG. 3A, the first external monitor 301 is connected to the camera body 100 by the cable 10. When using the digital camera 1, the user installs the first external monitor 301 in an arbitrary range that the cable 10 can reach.

  As shown in FIG. 3B, the second external monitor 302 is attached to the accessory shoe 15 provided on the upper part of the camera body 100. The second external monitor 302 has a movable leg 14, and the user can freely change the orientation of the second external monitor 302 in the vertical direction and the horizontal direction. Although not shown in FIG. 3B, the second external monitor 302 is desirably provided with an accessory shoe similar to the accessory shoe 15 included in the camera body 100. By configuring the second external monitor 302 as described above, an accessory (for example, a speedlight or the like) that can be installed on the accessory shoe 15 of the camera body 100 is attached to the accessory shoe provided on the second external monitor 302, and the second The external monitor 302 and its accessories can be used simultaneously.

  As shown in FIG. 3C, the third external monitor 303 is completely separated from the camera body 100. When using the digital camera 1, the user can use the third external monitor 303 at any position where wireless communication with the digital camera 1 is possible.

  In addition, the installation method of each external monitor described above is an example, and these may be combined as appropriate. For example, the first external monitor 301 that performs data communication via the cable 10 and the third external monitor 303 that performs wireless data communication may be configured to be attachable to the accessory shoe 15. In this case, data communication may be performed by the cable 10 or wirelessly, and power may be supplied from the electrical contact group 122 to each external monitor. Alternatively, the second external monitor 302 may be separable from the camera body 100 by connecting the second external monitor 302 and the accessory shoe 15 with a cable or the like. In addition to the rear monitor 112, another monitor may be provided on the camera body 100.

(Description of how to manage each monitor)
The body control device 109 assigns a unique management number to the external monitor 300 (any one of the first external monitor 301, the second external monitor 302, and the third external monitor 303) that is connected to the rear monitor 112. The management number is an integer starting from 0, and a monitor having a smaller management number is used to display more important information. In the following description, a monitor with a management number of 0 is called a main monitor, and another monitor with a management number of 1 or more is called a sub monitor. Specific display contents on the main monitor and sub-monitor will be described in detail later.

  When the external monitor 300 is not connected, the rear monitor 112 becomes the main monitor with the management number 0. In order to simplify the description of the embodiment, the description will be continued assuming that there is no sub-monitor.

  When the first external monitor 300 is connected, the body control device 109 executes an external monitor initialization process. In the external monitor initialization process, the body control device 109 receives the display specifications of the external monitor 300 through data communication with the external monitor 300. Then, the body control device 109 compares the received display specification of the external monitor 300 and the display specification of the rear monitor 112, and determines a management number to be assigned to the external monitor 300 and the rear monitor 112.

  FIG. 4 is a flowchart of the external monitor initialization process executed by the body control device 109. First, in step S100, the body control device 109 determines whether or not the first external monitor 300 is connected. If the external monitor 300 is not connected, step S100 is repeated or this flowchart is terminated, and if the external monitor 300 is connected, the process proceeds to step S110.

  In step S <b> 110, the body control device 109 receives data related to the specifications of the external monitor 300 from the external monitor 300 through data communication with the external monitor 300. In the present embodiment, this data is data representing the number of display pixels of the external monitor 300 (for example, horizontal 640 pixels × vertical 480 pixels).

  In subsequent step S120, body control device 109 compares the number of display pixels of external monitor 300 (represented by the data received in step S110) with the number of display pixels of rear monitor 112. When the number of display pixels of the external monitor 300 is larger than the number of display pixels of the rear monitor 112, the process proceeds to step S130, where the body control device 109 sets the management number of the external monitor 300 to 0 and sets the management number of the rear monitor 112. Set to 1. That is, when the display capability of the external monitor 300 is superior to the display capability of the rear monitor 112, the body control device 109 treats the external monitor 300 as a main monitor and treats the rear monitor 112 as a sub monitor.

  On the other hand, if the number of display pixels of the external monitor 300 is less than or equal to the number of display pixels of the rear monitor 112, the process proceeds to step S140, where the body control device 109 sets the management number of the external monitor 300 to 1, and the management number of the rear monitor 112 Is set to 0. That is, if the display capability of the external monitor 300 is inferior to the display capability of the rear monitor 112 or if the display capability of the external monitor 300 and the display capability of the rear monitor 112 are the same, the body control device 109 300 is treated as a sub monitor, and the rear monitor 112 is treated as a main monitor.

  The monitor initialization process executed when the first external monitor 300 is connected has been described above. A plurality of external monitors 300 can be connected to the camera body 100, and the body control device 109 also executes monitor initialization processing when the second and subsequent external monitors 300 are connected. In this monitor initialization process, in step S120, the display specifications of the rear monitor 112, the display specifications of the newly connected external monitor 300, and the display specifications of the already connected external monitor 300 are compared with each other. Order display capabilities. Then, the management numbers are assigned in ascending order from the monitor having the best display capability.

(Description of contents displayed on main monitor and sub monitor)
Next, contents displayed on the main monitor and the sub monitor by the body control device 109 will be described together with the operation of the digital camera 1. The digital camera 1 is in one of the following operating states: (1) power off state, (2) shooting standby state, (3) live view state, and (4) moving image shooting state.

(1) Power-off state When the digital camera 1 is in the power-off state, power consumption by the digital camera 1 is kept low, and the user cannot perform shooting. When the user turns on a power switch (not shown), the camera body 100 transitions to a shooting standby state.

(2) Shooting standby state FIG. 5 is a diagram illustrating an example of display on the main monitor and the sub monitor in the shooting standby state. When the sub-monitor does not exist (that is, the external monitor 300 is not connected), the body control device 109 displays the screen 20 shown in FIG. 5A on the main monitor (that is, the rear monitor 112). The screen 20 displays a list of current shooting setting items 22a to 22f.

  The shooting setting item 22a is a shutter speed at the time of shooting. The shooting setting item 22b is a shooting aperture value. The shooting setting item 22c is white balance (for example, auto, fluorescent lamp, incandescent lamp, etc.). The shooting setting item 22d is ISO sensitivity. The shooting setting item 22e is an AF mode (for example, auto, single, continuous, etc.). The shooting setting item 22f is an exposure correction value. Note that each shooting setting item described here is an example, and there may be items other than these on the screen 20, or only a part of these shooting setting items may be displayed on the screen 20. Good.

  Among the shooting setting items 22a to 22f, the cursor 21 is superimposed on the shooting setting item 22d. A cursor 21 indicates that the shooting setting item 22d is in a selected state. The user moves the cursor 21 by a touch operation on the touch panel 113 or an operation member (not shown) (for example, a cursor key that can be pressed in the vertical and horizontal directions), and selects any one of the shooting setting items 22a to 22f. Can be. When the shooting setting item 22d regarding the ISO sensitivity is selected, the screen 20 displayed on the main monitor (that is, the rear monitor 112) is changed to a screen 30 shown in FIG. 5B. That is, the submenu 33 that lists the ISO sensitivity values that can be set is displayed in the vicinity of the shooting setting item 22d that was in the selected state on the screen 20 (FIG. 5A).

  The submenu 33 includes an item 32a corresponding to ISO 100, an item 32b corresponding to ISO 200, an item 32c corresponding to ISO 400, an item 32d corresponding to ISO 640, an item 32e corresponding to ISO 800, an item 32f corresponding to ISO 1000, and ISO 1200. The item 32g corresponding to is included. Note that the submenu 33 may include more items (settable ISO sensitivity values). If the submenu 33 does not fit on the screen 30, the submenu 33 may be configured to be scrollable in the vertical direction. Of the items 32a to 32g of the submenu 33, the cursor 31 is superimposed on the item 32b in the same manner as the shooting setting item 22d, indicating that the item 32b is in a selected state. The user can select any one of the items 32 a to 32 g of the submenu 33 by moving the cursor 31 by a touch operation on the touch panel 113 or an operation member (not shown). For example, if the item 32c corresponding to ISO400 is selected, it is updated to ISO400 (that is, a value corresponding to item 32c).

  That is, the body control device 109 first displays the first layer menu (shooting setting items 22a to 22f) on the main monitor, and when any one item is selected from the menu, the second layer is the lower layer. Menu (submenu 33) is displayed.

  On the other hand, when in the shooting standby state and the sub monitor exists, the body control device 109 displays the screen 40 shown in FIG. 5C on the main monitor, and displays the screen 50 shown in FIG. 5D on the sub monitor. . On the screen 40 displayed on the main monitor, the current shooting setting items 22a to 22f are displayed in a list as in FIG. On the other hand, the screen 50 displayed on the sub-monitor displays items 32a to 32g that can be set to the currently selected shooting setting item 22d (that is, ISO sensitivity) among the shooting setting items 22a to 22f displayed on the main monitor. Will be listed.

  Since a display device with a high pixel count is suitable for displaying a large number of shooting setting items as a list, the body control device 109 displays a list of shooting setting items on the main monitor. Further, when changing the individual shooting settings displayed in the list, it is easy to operate if values that can be set for the individual shooting settings are displayed in a list in advance. Therefore, the body control device 109 displays a list of values that can be set for each shooting setting on the sub monitor, and allows the user to select a value that is desired to be set. When a value different from the current setting is selected on the body control device 109 and the sub-monitor, the shooting setting item displayed on the main monitor is updated accordingly.

  That is, the body control device 109 displays the first layer menu (shooting setting items 22a to 22f) on the main monitor, and the second layer menu (settable values) related to the first layer menu on the sub monitor. 32a to 32g) are displayed.

  When the user performs a predetermined operation (for example, a half-press operation of the release switch) in the shooting standby state, the body control device 109 executes an automatic focus adjustment process. Specifically, after the focus detection device 106 detects the focus adjustment state of the imaging optical system, the lens control device 209 drives the focusing lens 204 based on the detection result. The body control device 109 displays no information on the main monitor and the sub-monitor during execution of the automatic focus adjustment process when the user detects that the user has used the optical viewfinder by an eye sensor or the like. This is because it does not prevent the user from looking into the optical viewfinder and confirming the focus position and composition. Note that a live view state described later may be set when the power switch of the digital camera 1 is turned on, and a shooting standby state may be set according to an operation of an operation member (not shown).

  When the user performs a predetermined operation (for example, full pressing operation of the release switch) after executing the automatic focus adjustment process, the body control device 109 executes the photographing process. In the shooting process, the body control device 109 temporarily moves the quick return mirror 103 and the sub mirror 105 to the retracted position, and then causes the image sensor 104 to capture the subject image. Then, the image signal output from the image sensor 104 is subjected to various image processes to create image data, and the image data is stored in a storage medium (not shown) (for example, a memory card).

  After execution of the photographing process, the body control device 109 displays the image data photographed by the photographing process on the main monitor for a predetermined time (for example, 5 seconds) so that the user can confirm the photographing result (so-called postview display). . At this time, the body control device 109 causes the sub-monitor to display shooting settings when shooting the image data (values of the shooting setting items shown in FIG. 5A), a histogram of the image data, and the like. Thus, if the captured image is displayed on the monitor (main monitor) having the larger number of display pixels, the captured image can be confirmed in detail. On the other hand, the shooting settings and the like are supplementary information and do not require a large number of display pixels, and therefore may be displayed on the sub monitor.

  Note that the body control device 109 may display the previous captured image instead of the shooting setting, histogram, or the like as the display on the sub monitor. In other words, the body control device 109 may display the captured image on the main monitor and the sub monitor according to the time axis. In addition, when there are a plurality of sub-monitors, the body control device 109 displays the previous captured image on one of the sub-monitors, and displays the captured images captured so far on the other sub-monitor as thumbnails. The contents of not only the immediately preceding captured image but also the previously captured image can be confirmed as appropriate, and the usability is further improved.

(3) Live View State When the digital camera 1 is in the shooting standby state, if the user performs a predetermined operation (for example, pressing a live view button), the digital camera 1 transitions to the live view state. When transitioning to the live view state, the body control device 109 moves the quick return mirror 103 and the sub mirror 105 to the retracted position.

  While the digital camera 1 is in the live view state, the body control device 109 causes the image sensor 104 to capture a subject image every predetermined cycle (for example, 1/60 second), creates a through image, and displays it on the main monitor. On the main monitor, a rectangular cursor representing the focus area is displayed so as to be superimposed on the through image. The user can move the rectangular cursor using an operation member (not shown) (for example, a cursor key).

  During the live view state, the body control device 109 enlarges and displays a certain area centered on the cursor in the entire through image displayed on the main monitor on the sub monitor, and assists the user in adjusting the focus. The body control device 109 moves the area to be enlarged and displayed on the sub monitor following the movement of the cursor.

  When the user performs a predetermined operation (for example, a half-press operation of the release switch) when the camera body 100 is in the live view state, the body control device 109 executes the automatic focus adjustment process by the focus detection device 106 described above.

  When the user performs a predetermined operation (for example, full pressing operation of the release switch) after executing the automatic focus adjustment process, the body control device 109 executes the photographing process. In the photographing process, the body control device 109 causes the image sensor 104 to capture a subject image. Then, the image signal output from the image sensor 104 is subjected to various image processes to create image data, and the image data is stored in a storage medium (not shown) (for example, a memory card). After execution of the photographing process, the body control device 109 performs a postview display on the main monitor. Since the contents of the postview display are as described above, a description thereof will be omitted.

(4) Moving Image Shooting State When the digital camera 1 is in the shooting standby state or live view state, when the user performs a predetermined operation (for example, pressing the moving image shooting button), the digital camera 1 transitions to the moving image shooting state. At this time, when the quick return mirror 103 and the sub mirror 105 are not in the retracted position, the body control device 109 moves them to the retracted position. Thereafter, the body control device 109 starts moving image shooting by the image sensor 104. That is, a subject image is picked up by the image pickup device 104 every predetermined cycle (for example, 1/60 second), and various image processing is performed on the image pickup signal output from the image pickup device 104 to create one frame of a moving image. The created frame is temporarily stored in a storage medium (not shown) (for example, a DRAM or a memory card).

  The body control device 109 displays each frame of the captured moving image on the main monitor during moving image shooting and displays a thumbnail of some frames of the captured moving image on the sub-monitor. This part of the frame is, for example, a frame selected at intervals of 1 second, a frame in which a scene change is performed (a frame that has changed significantly from the previous frame), or the like. The body control device 109 superimposes each frame being shot on the main monitor during movie shooting, and displays information indicating that the movie is being shot (for example, a frame surrounding the through image and an icon indicating that the movie is being shot). indicate.

  When a user performs a predetermined operation during moving image shooting (for example, when a moving image shooting button is pressed), the body control device 109 ends moving image shooting, and temporarily stores the moving image data composed of each frame as a storage medium (not shown, for example, a memory). Card). The digital camera 1 transitions to a state before starting moving image shooting (that is, a shooting standby state or a live view state).

In the above description, the external monitor 300 has been described as an example. However, an additional monitor may be incorporated in the camera system 1.
FIG. 6 is a diagram showing an example in which the built-in monitor 114 is provided below the rear monitor 112. In this case as well, the specifications (including the layout) of the built-in monitor 114 and the rear monitor 112 are compared, and one is used as the main monitor and the other is used as the sub monitor. In FIG. 6, the display areas of the built-in monitor 114 and the rear monitor 112 are the same, but different display areas may be used. In FIG. 6, the built-in monitor 114 is provided below the rear monitor 112, but it may be provided on the upper side, the right side, and the left side, or may be provided obliquely, and the number thereof is not limited to one. Further, the built-in monitor 114 may be detachable from the camera system 1.

According to the camera system according to the first embodiment described above, the following operational effects can be obtained.

  The following modifications are also within the scope of the present invention, and one or a plurality of modifications can be combined with the above-described embodiment.

(Modification 1)
In the above-described embodiment, the management number is determined by comparing the number of display pixels as the specification between monitors, but specifications other than the number of display pixels may be compared. For example, data representing the area of the display screen (for example, horizontal 101.6 mm × vertical 76.2 mm) may be received as the specification data described above, and a monitor with a large area may be handled as a main monitor and a small monitor as a sub monitor. . In addition, various specifications such as aspect ratio, refresh rate, which is the screen drawing speed of the monitor, response speed, which is the response time to the electric field of the liquid crystal molecules, power consumption, presence of built-in battery, etc. can be used to determine the management number. it can. For example, live view display may be performed using a monitor with a faster refresh rate or response speed, or live view display may be performed using a monitor with less power consumption.

(Modification 2)
The content displayed on the external monitor 300 may be switched according to the specification data described above. For example, when the number of display pixels of the external monitor 300 or the area of the display screen is greater than a certain value, the body control device 109 displays a plurality of captured images that have been captured so far as thumbnails on the external monitor 300, When the area of the display screen is less than a certain value, a new one of the plurality of photographed images with the latest photographing date / time may be displayed on the external monitor 300 with priority.

  As another example, data indicating whether or not the external monitor 300 includes a touch panel is received as specification data. When the external monitor 300 includes a touch panel, a UI (user interface) suitable for touch operation is displayed on the touch panel. If not provided, UIs suitable for operations using cursor keys or the like may be displayed on the external monitor 300, respectively. For example, when displaying a software keyboard, if each key is too small, the touch operation becomes difficult. Therefore, the body control device 109 displays a software keyboard with a large key pitch when the external monitor 300 has a touch panel, and displays a software keyboard with a small key pitch when the external monitor 300 does not have a touch panel. Similarly, in an example in which a software keyboard is displayed, the key pitch can be changed depending on whether the number of display pixels is large or small. That is, when the number of display pixels is large, a larger number of keys are displayed, and when the number of display pixels is small, the number of keys displayed simultaneously is decreased. In this way, by changing the configuration of the screen displayed on the external monitor 300 according to the specifications of the external monitor 300, it is possible to provide an imaging device that is easier to use.

(Modification 3)
In the embodiment described above, the external monitor 300 is a single-function display device having only a monitor function. However, for example, an imaging device having a rear monitor similar to the digital camera 1 can be used as an external monitor. A tablet type (slate type) portable information terminal can also be used as an external monitor.

(Modification 4)
The information displayed on the main monitor and the sub monitor may be different from the above-described embodiments. As long as a plurality of pieces of information having different priorities are used, any information can be arranged and displayed in the order of monitor management numbers.

(Modification 5)
In the first embodiment described above, a so-called single-lens reflex digital camera capable of exchanging lenses has been described as an example. The present invention is not limited to such an embodiment. For example, the present invention can be applied to portable electronic devices such as a lens-integrated digital camera, a lens interchangeable digital camera (mirrorless camera) that does not have the quick return mirror 103, and a tablet computer. Note that such various portable electronic devices may be in a live view state after being turned on or in an imaging mode. In addition, a part of the configuration of the above-described camera system (for example, an optical viewfinder) can be omitted.

  As long as the characteristics of the present invention are not impaired, the present invention is not limited to the above-described embodiments, and other forms conceivable within the scope of the technical idea of the present invention are also included in the scope of the present invention. .
