In the present embodiment, a camera system 1 will be described as an example of an imaging apparatus. The camera system 1 is a lens-interchangeable single-lens reflex camera that functions as an imaging device by combining a camera body 2 and a replaceable photographing lens 3.

  The photographic lens 3 includes a lens group 4 including a focus lens, a zoom lens, and an anti-vibration lens, an aperture 5, an angular velocity sensor 6 that detects shake of the camera system 1, a driving device (not shown) that drives the lens group 4, and the like. The angular velocity sensor 6 detects an angular velocity around at least two axes orthogonal to the optical axis. The drive device has a plurality of motors composed of, for example, a vibration wave motor and a VCM, drives the focus lens in the optical axis direction, and drives the anti-vibration lens in a direction different from the optical axis direction. The photographing lens 3 has a lens CPU 7 that controls the entire photographing lens 3 and cooperates with the camera body 2.

  The camera body 2 retreats so that the light beam from the photographic lens 3 is reflected and guided to the finder optical system 11 and the light beam from the photographic lens 3 is incident on the image sensor 12 composed of a CCD, a CMOS, or the like. A main mirror 13 that swings with respect to the retracted position is provided. A partial area of the main mirror 13 is a semi-transmissive area, and the camera body 2 includes a sub-mirror 15 that reflects the light beam transmitted through the semi-transmissive area to the focus detection sensor 14. The sub mirror 15 swings in conjunction with the main mirror 13, and when the main mirror 13 takes the retracted position, the sub mirror 15 also retracts from the light flux. The focus detection sensor 14 detects the focus state of the incident light beam by the phase difference method.

  The light beam reflected by the main mirror 13 at the reflection position is guided to the finder optical system 11 through the focusing screen 16 and the pentaprism 17. The finder optical system 11 is composed of a plurality of lenses, and the user can check the object field by the finder optical system 11.

  A part of the light beam passing through the pentaprism 17 is guided to the photometric sensor 18. The photometric sensor 18 measures the luminance distribution of the object scene by measuring the light beam incident on the photographing lens 3 for each of a plurality of regions. Further, the camera body 2 includes a microphone 31 that captures the sound of the object scene at a position that does not interfere with the photographing lens 3 in the vicinity of the mount portion of the photographing lens 3, and a speaker 32 in the vicinity of the finder optical system 11.

  When the main mirror 13 is in the retracted position, the light beam from the photographic lens 3 enters the image sensor 12 via the low-pass filter 19. A substrate 20 is provided in the vicinity of the image sensor 12, and a rear monitor 33 is provided behind the substrate 20 so as to face the outside. In the vicinity of the rear monitor 33, a distance measuring sensor 34 such as an ultrasonic sensor or an infrared sensor is provided. The distance measuring sensor 34 measures the distance between the user and the rear monitor 33.

  FIG. 2 is a rear view of the camera system 1. In particular, a state in which a menu screen is displayed on the rear monitor 33 is shown. As shown in the figure, an operation switch 35 having a cross switch is provided in the vicinity of the rear monitor 33. The user operates the operation switch 35 to move the cursor on the menu screen up / down / left / right to select a specific menu item. A determination button is provided at the center of the operation switch 35. The user instructs the execution of the menu item selected by the cursor by pressing the enter button. As described above, the distance measuring sensor 34 is provided in the vicinity of the rear monitor 33.

  FIG. 3 is a block diagram of the camera system 1 according to the present embodiment. The substrate 20 includes a camera body CPU 21, a drive circuit 22 that drives the image sensor 12, an A / D conversion circuit 23 that converts the output of the image sensor 12 into a digital signal, an image processing control circuit 24 that includes an ASIC, and the image sensor 12. A contrast AF circuit 25 for extracting a high-frequency component of the signal from the signal, a display control circuit 26, and the like. The camera body CPU 21 controls the entire camera system 1.

  The image processing control circuit 24 performs image processing such as white balance adjustment, sharpness adjustment, gamma correction, and gradation adjustment on the image signal converted into the digital signal, and also performs image compression such as JPEG to generate an image file. Generate. The generated image file is stored in the image recording medium 41. The image recording medium 41 may be a recording medium such as a flash memory that is detachable from the camera body 2, or may be a recording medium such as an SSD (Solid State Drive) built in the camera body 2. .

  The image signal subjected to the image processing is displayed on the rear monitor 33 under the control of the display control circuit 26. If the image signal taken immediately after shooting is displayed for a predetermined time, a REC review display that allows the user to visually recognize an image corresponding to the image file recorded on the image recording medium 41 can be realized. Further, a live view display can be realized by sequentially displaying an object scene image that is continuously photoelectrically converted by the image sensor 12 on the rear monitor 33 without being recorded on the image recording medium 41. Further, an object scene image that is continuously photoelectrically converted by the image sensor 12 is converted into, for example, MPEG, H.264, or the like. If moving image compression processing such as H.264 is performed by the image processing control circuit 24 and recorded in the image recording medium 41, moving image shooting can be realized. At this time, the sound of the object scene collected by the microphone 31 is also compressed and recorded in synchronization with the moving image data. The frame rate of the generated moving image is selected and set from a plurality of frame rates such as 30 fps, for example.

  The contrast AF circuit 25 extracts a high-frequency component of the imaging signal from the imaging device 12 to generate an AF evaluation value signal, and detects a focus lens position where the AF evaluation value signal becomes maximum. Specifically, a predetermined high-frequency component is extracted from the image signal input from the image processing control circuit 24 using a bandpass filter, and detection processing such as peak hold and integration is performed to generate an AF evaluation value signal. . The generated AF evaluation value signal is output to the camera body CPU 21.

  The lens CPU 7 drives the anti-vibration lens in the photographing lens 3 in a direction different from the optical axis direction so as to cancel the camera shake detected by the angular velocity sensor 6 to realize optical camera shake correction. The camera shake correction is not limited to such optical camera shake correction, but adopts an image sensor drive type camera shake correction in which a drive mechanism is added to the image sensor 12 to drive in a direction different from the optical axis direction and cancel the camera shake. You can also. Further, an electronic camera shake that calculates a motion vector between a plurality of images output from the image processing control circuit 24 and controls image readout position so as to cancel the calculated motion vector between images and cancels camera shake. Corrections can also be employed. Optical camera shake correction and image sensor-driven camera shake correction are particularly suitable for still image shooting and are also applied to moving image shooting. Electronic camera shake correction is suitable for moving image shooting. These methods can be selectively and additionally employed.

  As described above, the photometric sensor 18 measures the luminance distribution of the object scene by measuring the light beam incident on the photographing lens 3 for each of a plurality of regions. The photometric sensor 18 outputs the measurement result to the camera body CPU 21. The camera body CPU 21 calculates an exposure value according to the selected photometry mode. As a metering mode, a split metering mode that balances bright and dark parts, a center-weighted metering mode that properly exposes the center of the screen, a spot metering mode that properly exposes a narrow area of the selected focus point, and the like can be selected. .

  The flash ROM 42 is an EEPROM (registered trademark), and is a storage device that stores various adjustment values and setting values in addition to a program for operating the camera system 1. Specifically, AF adjustment data, AE adjustment data, switch setting history, and the like are stored. In particular, various setting values set by the user are classified into a plurality of menu items of the camera system 1 according to the type, and are managed hierarchically in a tree structure in each classification. The switch setting history will be described later.

  The RAM 43 is a high-speed RAM such as a DRAM in which a program stored in the flash ROM 42 is expanded and the camera body CPU 21 can access at high speed. In particular, various adjustment values and setting values that are frequently referred to are also copied from the flash ROM 42 to facilitate access from the camera body CPU 21. The display control circuit 26 performs display control for displaying the menu screen read from the flash ROM 42 on the rear monitor 33 in addition to the image processed as described above.

  The tilt sensor 44 detects the tilt of the camera system 1. The tilt sensor 44 includes an acceleration sensor, an angular velocity sensor, and the like, and detects at least a pitch angle that is a tilt in the front-rear direction of the camera system 1. The tilt sensor 44 outputs the detection result to the camera body CPU 21.

  The distance measuring sensor 34 measures the distance between the user and the rear monitor 33 as described above. The distance measuring sensor 34 is installed adjacent to the rear monitor 33 in the rear surface of the camera system 1. Then, when the user's face approaches the rear monitor 33, the distance measuring sensor 34 measures the distance and outputs the measurement result to the camera body CPU 21.

  The release SW 45 is a two-stage switch. When the user half-presses the release SW 45, the camera body CPU 21 performs shooting preparation operations such as autofocus and photometry. Further, when the user fully presses the release SW 45, the camera body CPU 21 starts a still image / moving image shooting operation.

  FIG. 4 is a diagram for explaining the concept of the present embodiment. The distance measuring sensor 34 measures the distance D between the user observing the display on the rear monitor 33 and the rear monitor 33.

  When observing the information displayed on the rear monitor 33, the user adjusts the distance between the eyeball and the rear monitor 33 consciously or unconsciously according to the displayed information. For example, when a small icon is displayed or a large number of characters are displayed, the rear monitor 33 is moved away for a presbyopic user, and is moved closer for a near-sighted user. Therefore, when confirming a setting, the user must operate the operation switch 35 to instruct the display of the setting, and then perform a two-stage operation of moving the camera system 1 to be held away or closer. did not become.

  On the other hand, the camera system 1 according to the present embodiment performs control so that each display is executed at an image display observation distance and a function setting display observation distance that the user feels optimal. That is, the user can set the observation distance and the display content displayed at that time in advance, and the camera system 1 records the set content as a display change table. Then, the camera system 1 acquires the distance to the user as an observation distance by the distance measuring sensor 34 during operation, and compares the result with the display change table to change the content displayed on the rear monitor 33. By such control, the user can automatically display the contents to be displayed at a distance corresponding to the contents that can be easily observed by simply moving the camera system 1 to be gripped away or close. Hereinafter, specific control and change of the display screen will be described in detail.

  FIG. 5 is a diagram for explaining the display change table. The display change table 50 is a table that is referred to when the display control circuit 26 executes the display change process in the present embodiment. As will be described later, the display change table 50 is updated in accordance with an instruction from the user. The updated display change table 50 is stored in the flash ROM 42.

  As shown in FIG. 5, in the display change table 50, “mode” and “change contents” are defined corresponding to each “distance range”. In the “distance range”, a set distance range in the measurable range of the distance measuring sensor 34 is defined. The “mode” includes a “shooting mode” for performing the above live view display, a “playback mode” for displaying the image data recorded on the image recording medium 41, and a “function setting mode” for displaying the menu screen. Either is specified. The “change contents” defines the mode of display contents to be changed in each mode.

  According to the example of the figure, “min-50”, “50-100”, “100-150”, “150-250”, “250-300”, “300-400”, which are divided distance ranges, A first setting line 51 to a seventh setting line 57 are defined for each of “400 to max”. In the display change table 50, the distance range from the first setting line 51 to the third setting line 53 corresponds to the “playback” mode, and the fourth setting line 54 and the fifth setting line 55 correspond to the “shooting” mode. The sixth setting line 56 and the seventh setting line 57 indicate that they correspond to the “function setting” mode.

  For the “reproduction” mode, “displayed number” is defined as a change content. As a specific content in changing the number of displayed sheets, the first setting line 51 defines the display based on the “first display number”, and similarly, the second setting line 52 displays based on the “second display number”. However, the third setting line 53 defines the display based on the “third display number”. For example, if the distance measured by the distance measuring sensor 34 is 70 mm, the second setting row 52 corresponding to the distance range including the distance 70 mm is referred to, and after switching to the reproduction mode, the second display number is set. Simultaneously arranged image display is executed. The specific display mode change will be described later.

  Further, “status display” is defined as a change content for the “photographing” mode. As specific contents in the change of the status display, the fourth setting line 54 defines “no information display”, and similarly, the fifth setting line 55 defines “information display present”. Yes. For example, if the distance measured by the distance measuring sensor 34 is 280 mm, the fifth setting row 55 corresponding to the distance range including the distance 280 mm is referred to, and the information display is performed as the image display after switching to the shooting mode. Live view display is executed. The specific display mode change will be described later.

  In addition, for the “function setting” mode, “hierarchy switching” is defined as a change content. As specific contents in the change of hierarchy switching, “first hierarchy display” is defined in the sixth setting line 56, and similarly, “second hierarchy display” is defined in the seventh setting line 57. Yes. For example, if the distance measured by the distance measuring sensor 34 is 350 mm, the sixth setting row 56 corresponding to the distance range including the distance 350 mm is referred to, and the function setting display is performed after switching to the function setting mode. Menu item display in the first layer is executed. The specific display mode change will be described later.

  FIG. 6 is a diagram for explaining a display change table update process. The display control circuit 26 cooperates with the camera body CPU 21 to update the display change table 50 described above in response to a user input.

  As shown in FIG. 6A, the display control circuit 26 is provided with a playback tab 61, a shooting tab 62, a setup tab 63, and a help tab 64, each of which is classified as a tab, at the left end of the menu screen. Menu items related to reproduction are grouped in a reproduction tab 61. Similarly, menu items related to shooting are grouped in the shooting tab 62, and menu items related to the use environment of the camera system 1 are grouped in a setup tab 63. The help tab 64 is a group of explanatory items that can be selected when there is a help display related to the displayed item. The menu item group collected in the setup tab 63 includes an item “display change table setting”. When the user designates the setup tab 63 and designates the item “display change table setting”, the display control circuit 26 displays the menu screen shown in FIG.

  As shown in FIG. 6A, the title column 65 at the top of the menu screen displays the name of the item “display change table setting”. A change process execution input field 66 is provided below the title field 65. The user selects “YES” in the change process execution input field 66 when he wants to execute the display change process according to the distance. On the other hand, when the user does not want to execute the display change process according to the distance, the user selects “NO” in the change process execution input field 66. Note that the input information in the change process execution input field 66 is stored in the flash ROM 42.

  The display control circuit 26 includes a distance range input field 67, a mode input field 68, and a change content input field 69 below the change process execution input field 66. In the menu screen of FIG. 6A, the first input line 70, the second input line 71, and the third input line 72 are the first setting line 51, the second setting line 52, and the third setting line of the display change table 50, respectively. 53 shows the setting contents of each item. A scroll operation mark 73 is provided below the third input line 72. In response to the user's operation of the scroll operation mark 73, the display control circuit 26 changes the setting lines after the fourth setting line 54 of the display change table 50 to the first input line 70, the second input line 71, and the third input line 72.

And a second insertion mark 75 for instructing the insertion of the input line. When the user designates the first insertion mark 74 or the second insertion mark 75 with the cursor, the display control circuit 26 inserts a new input line at a location corresponding to the designated insertion mark.

  The user changes each numerical value in the distance range input field 67 to change the distance range in the setting line displayed in each input line. In addition, the user selects one mode from the mode input field 68 and designates the mode of the setting line displayed on each input line. Further, the user selects the presence / absence of the change content input field 69 and designates the presence / absence of the change content of the setting line displayed in each input line.

  When the user designates “Yes” in the change content input field 69, the display control circuit 26 causes the rear monitor 33 to display a menu screen for inputting the change content. FIG. 6B is a menu screen when “Yes” is designated in the change content input field 69 of the first input line 70 in FIG. As shown in FIG. 6B, a first item column 76, a second item column 77, and a third item column 78 are provided in the center of the screen. In the first item column 76, the second item column 77, and the third item column 78, "status display", "view angle change", and "moving image playback speed" are displayed, respectively. The items of “status display”, “view angle change”, and “moving image playback speed” are items of content change processing in the “playback” mode image display specified in the mode input field 68 of the first input line 70. . Details will be described later.

  When the user designates a menu item to be displayed in the first item column 76, the second item column 77, and the third item column 78, the display control circuit 26 is a menu screen for inputting detailed change contents of the item. Is displayed on the rear monitor 33. FIG. 6C is a menu screen when “status display” in FIG. 6B is designated. As shown in FIG. 6C, a number input field 79 for inputting the number of displayed sheets is provided at the center of the screen. When the user inputs the number in the number input field 79, the camera body CPU 21 displays the display change table in accordance with the input information on the menu screens of FIGS. 6 (a), 6 (b) and 6 (c). 50 is updated.

  Here, the display change process of this embodiment will be described with reference to a screen example. In the present embodiment, the rear monitor 33 and the distance measuring sensor 34 function as a display unit and a distance measuring unit, respectively. The lens CPU 7, the image sensor 12, the drive circuit 22, the A / D conversion circuit 23, and the image processing control circuit 24 function as an imaging unit that captures an image of a subject and acquires image data. The display control circuit 26 functions as a display control unit that executes the display change process of the present embodiment in cooperation with the camera body CPU 21. In the present embodiment, the display control circuit 26 executes the display change process with reference to the display change table shown in FIG.

  FIG. 7 is a diagram illustrating a first example of the present embodiment. The first embodiment is a display change process when the distance between the user and the rear monitor 33 is changed from the distance range of the sixth setting row 56 to the distance range of the fifth setting row 55 in the display change table 50 described above.

  First, when the distance measured by the distance measuring sensor 34 belongs to the distance range defined by the sixth setting line 56, for example, 350 mm, the display control circuit 26 determines the function setting mode according to the information of the sixth setting line. The menu screen of the first hierarchy in is displayed on the rear monitor 33. In the present embodiment, as shown in FIG. 7A, the first layer of the shooting menu is displayed.

Here, the user brings the camera system 1 close to himself / herself in order to photograph the subject. The display of the first layer of the shooting menu is continued until the distance measured by the distance measuring sensor 34 becomes 300 mm. When the distance measured by the distance measuring sensor 34 is less than 300 mm, the display control circuit 26 responds to the information in the fifth setting row 55 as shown in FIG. Change to the live view display in which 80 is superimposed.
The state information column 80 includes information such as a charging state of the camera system 1, an image size, a shutter speed, an F value, and an ISO sensitivity setting value. The second icon from the left in the status information column 80 indicates that “auto shake correction” in which the above-described shake correction is automatically executed is set. The third icon from the left in the state information column 80 is set to “spot metering mode” in the above-described metering modes.

  According to the first embodiment, the user can switch from the function setting display in the function setting mode to the image display in the shooting mode without operating the operation button or the like only by moving the camera system 1 to the shooting position. The change to the display in the different mode is not limited to the change between the function setting display in the function setting mode and the image display in the shooting mode. Depending on the setting of the display change table 50, a change between the function setting display in the function setting mode and the image display in the reproduction mode and a display change between the image display in the shooting mode and the image display in the reproduction mode can be performed.

  FIG. 8 is a diagram illustrating a second example of the present embodiment. The second embodiment is a display change process when the distance between the user and the rear monitor 33 is changed from the distance range of the fourth setting row 54 to the distance range of the fifth setting row 55 in the display change table 50 described above.

  First, when the distance measured by the distance measuring sensor 34 belongs to the distance range defined by the fourth setting row 54, for example, 200 mm, the display control circuit 26 in the shooting mode according to the information of the fourth setting row. An image display without information display is displayed on the rear monitor 33. In the present embodiment, as shown in FIG. 8A, a live view display without state information display in the shooting mode is displayed.

  Here, the user moves the camera system 1 away from himself / herself in order to check the status information of the camera system 1. The display of the first layer of the shooting menu is continued until the distance measured by the distance measuring sensor 34 becomes 250 mm. When the distance measured by the distance measuring sensor 34 is 250 mm or more, the display control circuit 26, according to the information in the fifth setting row 55, as shown in FIG. Change to the live view display in which 80 is superimposed.

  According to the second embodiment, the user can confirm the state of the imaging unit in the shooting mode without operating the operation button or the like only by moving the camera system 1 away from the shooting position. Note that the image display content changing process in the shooting mode is not limited to the state display process. As an example, a process of changing the angle of view of the live view display in accordance with the movement of the zoom lens of the lens group 4 executed by the lens CPU 7 according to the distance measured by the distance measuring sensor 34 is given.

  FIG. 9 is a diagram illustrating a third example of the present embodiment. The third embodiment is a display change process when the distance between the user and the rear monitor 33 is changed from the distance range of the third setting row 53 to the distance range of the first setting row 51 in the display change table 50 described above.

  First, when the distance measured by the distance measuring sensor 34 belongs to the distance range defined by the third setting row 53, for example, 120 mm, the display control circuit 26 in the reproduction mode according to the information of the third setting row. Twenty-five images are simultaneously displayed on the rear monitor 33. In this embodiment, as shown in FIG. 9A, 25 images in the reproduction mode are displayed in a 5 × 5 arrangement.

  Here, the user brings the camera system 1 closer to himself / herself in order to confirm the details of the image. Simultaneous display of 25 images in the playback mode is continued until the distance measured by the distance measuring sensor 34 reaches 100 mm. When the distance measured by the distance measuring sensor 34 is less than 100 mm, the display control circuit 26 responds to the information in the second setting row 52 as shown in FIG. The image display is changed to nine images based on the image of the center of the image.

  Furthermore, the user brings the camera system 1 closer to himself / herself in order to confirm the details of the image. Simultaneous display of nine images in the playback mode is continued until the distance measured by the distance measuring sensor 34 reaches 50 mm. When the distance measured by the distance measuring sensor 34 is less than 50 mm, the display control circuit 26, according to the information in the first setting row 51, as shown in FIG. The image display is changed to one image at the center of the image.

  According to the third display change example, the user can reduce the number of images simultaneously displayed on the rear monitor 33 without operating the operation buttons or the like simply by bringing the camera system 1 closer to confirm the details. Note that the image display content change process in the playback mode is not limited to the display number change process. An example is an image enlargement process or reduction process according to the distance measured by the distance measuring sensor 34. In addition, in the moving image reproduction mode, a moving image reproduction speed changing process corresponding to the distance measured by the distance measuring sensor 34 is also given as an example.

  FIG. 10 is a diagram illustrating a fourth example of the present embodiment. The fourth embodiment is a display change process when the distance between the user and the rear monitor 33 is changed from the distance range of the sixth setting row 56 to the distance range of the seventh setting row 57 in the display change table 50 described above.

  First, when the distance measured by the distance measuring sensor 34 belongs to the distance range defined by the sixth setting line 56, for example, 350 mm, the display control circuit 26 determines the function setting mode according to the information of the sixth setting line. The menu screen of the first hierarchy in is displayed on the rear monitor 33. In the present embodiment, as shown in FIG. 10A, the first layer of the shooting menu is displayed.

  Here, the user moves the camera system 1 away from the user in order to move to the next layer. The display of the first layer of the shooting menu is continued until the distance measured by the distance measuring sensor 34 becomes 400 mm. When the distance measured by the distance measuring sensor 34 is 400 mm or more, the display control circuit 26 corresponds to the information in the seventh setting row 57, as shown in FIG. Change to the display.

  According to the third display change example, the user can move to the next layer of the menu item group without operating the operation button or the like. Note that the image display content change processing in the function setting mode is not limited to hierarchical movement. An example of the cursor position changing process according to the distance measured by the distance measuring sensor 34 is given. An example of the process for changing the number of menu items on the menu screen according to the distance measured by the distance measuring sensor 34 is also given.

  FIG. 11 is a flowchart showing the display change process. In the present embodiment, the display control circuit 26 executes display change processing in cooperation with the camera body CPU 21. The display control circuit 26 starts a flow of display change processing when the power of the camera system 1 is turned on.

  In step S <b> 101, the display control circuit 26 determines whether to execute display change processing according to the distance between the user and the rear monitor 33. Specifically, the display control circuit 26 determines whether or not the user has set to execute the display change process on the display change setting screen described above. Note that user setting information is stored in the flash ROM 42, and the display control circuit 26 makes a determination with reference to the flash ROM 42. If the display control circuit 26 determines to execute the display change process, the process proceeds to step S102. If the display control circuit 26 determines not to execute the display change process, the display control circuit 26 proceeds to step S109.

  In step S <b> 102, the camera body CPU 21 controls the distance measuring sensor 34 to measure the distance between the user and the rear monitor 33. Then, the camera body CPU 21 transmits information on the measurement result of the distance measuring sensor 34 to the display control circuit 26.

  In step S <b> 103, the display control circuit 26 determines whether or not to maintain the current display state of the rear monitor 33 using information on the measurement result of the distance measuring sensor acquired from the camera body CPU 21. For example, the display control circuit 26 refers to the display change table 50, and when the distance indicated by the measurement result belongs to the distance range associated with the current display mode and there is no change content, the rear monitor 33 It is determined that the current display state of is maintained. The maintenance of the display-like body is that the display mode and display contents of the rear monitor are not changed according to the measurement result of the distance measuring sensor 34. Even if it is determined that the current display state of the rear monitor 33 is maintained in step S103, the display control circuit 26 changes the display on the rear monitor 33 according to the operation of the operation switch 35 by the user.

  Further, the display control circuit 26 may determine to maintain the current display state of the rear monitor 33 when the measurement result in step S102 indicates an error. When the user wants to maintain the display state temporarily, the distance measuring sensor 34 can be made to detect an error by closing the distance measuring sensor 34 with a finger. When it is determined that the current display state of the rear monitor 33 is to be maintained, the display control circuit 26 proceeds to step S113, and when it is determined that the current display state of the rear monitor 33 is not to be maintained, the display control circuit 26 proceeds to step S104. .

  In step S104, the display control circuit 26 refers to the display change table and determines whether or not to execute display change processing by mode switching. For example, when the function setting display is performed, the display control circuit 26 determines to execute the display change process by mode switching when the distance measured in step S102 belongs to the distance range associated with the image display. . The display control circuit 26 proceeds to step S106 if it is determined to execute the display change process by mode switching, and proceeds to step S105 if it is determined not to execute the display change process by mode switching.

  In step S105, the display control circuit 26 refers to the display change table and determines whether or not to change the content of the image display. For example, the display control circuit 26 determines that the display change process by the mode switching is to be executed when the change is set in the display change table 50 when the image is displayed. If the display control circuit 26 determines that the content of the image display is to be changed, the process proceeds to step S107. If the display control circuit 26 determines not to change the content of the image display, the process proceeds to step S108.

  In step S106, the display control circuit 26 executes display change processing by mode switching. A specific processing method is as described above in the first display change example.

  In step S107, the display control circuit 26 executes image display content change processing. The specific processing method is as described above in the second display change example and the third display change example.

  In step S108, the display control circuit 26 executes a function setting display content change process. The specific processing method is as described above in the fourth display change example.

  In step S113, the display control circuit 26 determines whether or not to end this flow. For example, the display control circuit 26 determines to end this flow when the power of the camera system 1 is turned off or when the camera system 1 shifts to a mode different from the shooting mode, playback mode, and function setting mode. If the display control circuit 26 determines not to end this flow, it returns to step S101.

  When the display control circuit 26 determines that the display change process is not executed in step S101, the display control circuit 26 cooperates with the camera body CPU 21 to display according to the user's operation and the distance between the user and the rear monitor 33 during the operation. Acquire history information indicating relevance. First, in step S <b> 109, the camera body CPU 21 acquires operation information from the operation switch 35. Next, in step S110, the display control circuit 26 determines the display state of the rear monitor 33 according to the operation indicated by the operation information. In step S <b> 111, the camera body CPU 21 controls the distance measuring sensor 34 in conjunction with the operation of the operation switch 35 to measure the distance between the user and the rear monitor 33.

  In step S112, the camera body CPU 21 causes the flash ROM 42 to store history information that associates the display state determined in step S110 with the distance measured in step S111. The display control circuit 26 may execute the display change process described above with reference to the history information. Specifically, the display control circuit 26 calculates a distance range for displaying an image of a shooting menu, a distance range for displaying an image of a reproduction menu, and a distance range for displaying a function setting by a user operation. And the display control circuit 26 performs the display change process by the above-mentioned mode switching based on the calculation result. The camera body CPU 21 may update the display change table 50 using history information.

  In the above embodiment, the display control circuit 26 may execute the display change process described above in consideration of the amount of change per unit time of the distance measured by the distance measuring sensor 34. For example, when the function setting display is displayed on the rear monitor 33, the display control circuit 26 performs a process of changing the hierarchy of the hierarchy menu according to the distance if the change amount of the distance per unit time is equal to or greater than the threshold value. If the amount of change per unit time of the distance is less than the threshold, the cursor position is changed according to the distance. In the display change table 50 described above, information on the amount of change per unit time of the distance, the mode, and the change content information may also be associated.

  In the above embodiment, the display control circuit 26 may change the luminance of the rear monitor 33 according to the measurement result of the distance measuring sensor 34. For example, the display control circuit 26 decreases the luminance of the rear monitor 33 as the rear monitor 33 approaches the user.

  Further, in the above embodiment, the display control circuit 26 may execute the above-described display change process in consideration of the tilt of the camera system 1 detected by the tilt sensor 44. Specifically, the display control circuit 26 tilts the camera system 1 forward when the pitch angle of the camera system 1 detected by the tilt sensor 44 is not less than a predetermined angle, for example, 45 degrees or more. It is determined that the function is set. Then, the display control circuit 26 displays the function setting display on the rear monitor 33, and executes the above-described function setting display content changing process. Thereafter, when the pitch angle of the camera system 1 returns to less than a predetermined angle, the display control circuit 26 determines that the function setting has been completed, and stops the function setting display content changing process.
