  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 is a cross-sectional view of a main part of a camera 10 according to the present embodiment. The camera 10 is used by combining the lens unit 20 and the camera body 30. A finder unit 40 is incorporated in the camera body 30. The lens unit 20 includes a lens group 21 arranged along the optical axis. The lens group 21 includes a plurality of lenses and guides incident subject light fluxes to the camera body 30. The plurality of lenses included in the lens group 21 are configured to be movable in the optical axis direction in response to instructions for focus adjustment and field angle adjustment. The lens unit 20 includes a lens mount 22 at a connection portion with the camera body 30, engages with a camera mount 31 included in the camera body 30, and is integrated with the camera body 30.

  The camera body 30 includes a main mirror 32 that reflects a subject light beam incident from the lens unit 20. The main mirror 32 rotates around the rotation axis and can take an oblique state in which the subject light beam is obliquely arranged around the optical axis and a retreat state in which the main mirror 32 is retreated from the subject light beam. When the subject luminous flux is guided to the viewfinder unit 40 side, the main mirror 32 is in an oblique state. When the subject luminous flux is guided to the image sensor 52 side, the main mirror 32 is in the retracted state.

  The finder unit 40 includes a focus plate 41, a transmissive display unit 42, an information display unit 43, a triangular prism 44, a pentaprism 45, an eyepiece optical system 46, a finder window 47, and a photometric sensor 48. The focus plate 41 is disposed at a position conjugate with the light receiving surface of the image sensor 52. The subject optical image primarily formed by the focus plate 41 is transmitted through the transmission display unit 42 and converted into an erect image by the pentaprism 45. The subject optical image converted into an erect image is observed by the user through the eyepiece optical system 46 and the finder window 47 in the first field area of the finder field area. The photometric sensor 48 disposed above the exit surface of the pentaprism 45 detects the luminance distribution of the subject from the subject optical image from the pentaprism 45.

  The transmissive display unit 42 includes a polymer dispersed liquid crystal (PN liquid crystal) or the like, and superimposes and displays information such as a focus detection area on the subject optical image formed on the focus plate 41. The information display unit 43 includes a liquid crystal panel and a backlight that illuminates the liquid crystal panel. The triangular prism 44 guides an optical image of various information displayed on the liquid crystal panel to the pentaprism 45. Optical images of various types of information are observed by the user through the eyepiece optical system 46 and the finder window 47 in the second field area of the finder field area adjacent to the first field area described above. The liquid crystal panel is configured by a dot matrix, and the display information of the information display unit 43 is configured such that the position can be changed in the range of the display area of the liquid crystal panel.

  A region near the optical axis of the main mirror 32 in the oblique state is formed as a half mirror, and a part of the incident subject light flux is transmitted therethrough. The transmitted subject luminous flux is reflected by the sub mirror 33 that rotates in conjunction with the main mirror 32 and guided to the AF optical system 34. The subject luminous flux that has passed through the AF optical system 34 enters the AF sensor 35. The AF sensor 35 is, for example, a plurality of photoelectric conversion element arrays that output phase difference signals from the received subject light flux. The sub mirror 33 retracts from the subject light beam in conjunction with the main mirror 32 when the main mirror 32 retreats from the subject light beam.

  A focal plane shutter 51 and an image sensor 52 are arranged along the optical axis behind the oblique main mirror 32. The focal plane shutter 51 opens during the exposure time, and closes so that the subject luminous flux does not enter the image sensor 52 except during the exposure time. The image sensor 52 is an element that photoelectrically converts a subject light beam that is transmitted through an optical system and uses, for example, a CCD or CMOS sensor. The electrical signal photoelectrically converted by the image sensor 52 is processed into image data by an image processing unit 54 which is a DSP mounted on the main board 53. In addition to the image processing unit 54, a camera system control unit 55, which is an MPU that integrally controls the system of the camera body 30, is mounted on the main board 53. The camera system control unit 55 manages the camera sequence and performs input / output processing of each component.

  A rear display unit 56 such as a liquid crystal monitor is disposed on the rear surface of the camera body 30, and a subject image processed by the image processing unit 54 on the main board 53 is displayed. The rear display unit 56 displays not only images but also various menu information. The camera body 30 accommodates a detachable secondary battery 57 and supplies power to the lens unit 20 as well as the camera body 30.

  FIG. 2 is a block diagram schematically showing the system configuration of the camera 10 according to the present embodiment. The camera 10 includes a lens control system centered on the lens system control unit 120 and a camera control system centered on the camera system control unit 55 corresponding to each of the lens unit 20 and the camera body 30. The lens control system and the camera control system exchange various data and control signals with each other via a connection portion connected by the lens mount 22 and the camera mount 31.

  The lens control system includes a lens memory 121 and a motor drive circuit 122. The lens memory 121 is an electrically erasable / recordable non-volatile memory, and is composed of, for example, an EEPROM (registered trademark). The lens memory 121 records constants, variables, programs, and the like necessary when the lens unit 20 operates so that they are not lost even when the lens unit 20 is not operating. The lens system control unit 120 controls a motor that moves the lenses included in the lens group 21 via the motor drive circuit 122.

  The image processing unit 54 included in the camera control system, in accordance with a command from the camera system control unit 55, converts the image signal photoelectrically converted by the image sensor 52 into an image according to a standardized image format such as JPEG. Process to data. The image processing unit 54 generates display image data in parallel with the image data processed for recording. The rear display control unit 133 causes the rear display unit 56 to display an image of image data for display in accordance with an instruction from the camera system control unit 55.

  Regardless of whether or not image data is recorded, if the image processing unit 54 sequentially generates image data for display according to the output of the image sensor and outputs it to the rear display unit 56, a live view function as an electronic viewfinder can be realized. Can do. The rear display control unit 133 causes the rear display unit 56 to display a live view image using sequential display image data in accordance with an instruction from the camera system control unit 55. The rear display control unit 133 may control the rear display unit 56 to display various types of information in a display area adjacent to the image display area that displays the live view image. In addition, the rear display control unit 133 also displays the reproduction image of the image data of the recording medium connected to the camera 10 and various menu items related to various settings of the camera 10 in the rear display unit 56 according to the instruction of the camera system control unit 55. Can be displayed.

  The camera memory 131 is an electrically erasable / recordable non-volatile memory, and is composed of, for example, an EEPROM (registered trademark). The camera memory 131 records constants, variables, programs, and the like necessary when the camera 10 is operating so that they are not lost even when the camera 10 is not operating. The camera memory 131 records data such as a predetermined threshold value and distance used in display control processing described later. The work memory 132 is a memory that can be accessed at high speed, such as a RAM, and has a role of temporarily storing image data being processed.

  The finder display control unit 134 is mounted on a penta substrate provided in the finder unit 40 and executes display control to display various information on the transmissive display unit 42 and the information display unit 43 in accordance with instructions from the camera system control unit 55. . Details of the display control processing of the finder display control unit 134 will be described later. The operation detection unit 135 detects that an operation member such as a cross key or a determination button provided on the camera body 30 has been operated, and outputs the detection result to the camera system control unit 55. The operation member includes a release button composed of push buttons that can be detected in two stages in the push-down direction. When the camera system control unit 55 detects that the switch SW1 is turned on, which is the first-stage depression of the release button, the camera system control unit 55 performs AF, AE, and the like as shooting preparation operations. The release button accepts an ON operation of the switch SW1 as a shooting preparation instruction. When the camera system control unit 55 detects that the switch SW2 is turned on, which is the second-stage depression of the release button, the camera element control unit 55 executes an object image acquisition operation by the image sensor 52.

  When the release button switch SW1 is turned on, the camera system control unit 55 cooperates with the lens system control unit 120 to execute phase difference AF corresponding to the output of the AF sensor 35. In addition, the camera system control unit 55 analyzes the photometric data of the photometric sensor 48 to calculate an appropriate exposure value, and determines the shutter speed, aperture value, and ISO sensitivity according to the appropriate exposure value and the shooting mode. Note that when the release button switch SW1 is turned on while the live view image is displayed, the image processing unit 54 generates an image for AF evaluation value calculation and acquires the luminance of the live view image. The camera system control unit 55 performs contrast AF in cooperation with the image processing unit 54. Also, the camera system control unit 55 calculates the appropriate exposure value by executing AE using the AF evaluation value calculation image, and determines the shutter speed, aperture value, and ISO sensitivity according to the appropriate exposure value and the shooting mode. To do.

  Next, a description will be given of a first embodiment for controlling display of a viewfinder field observed from the viewfinder window 47 of the viewfinder unit 40 in accordance with the luminance of the subject. In the first embodiment, the finder display control unit 134 serves as a changing unit that changes the position of the information displayed on the information display unit 43 in the finder field according to the luminance of the subject. The first embodiment will be described below separately for cases where the subject has high luminance and low luminance.

  FIG. 3 is a diagram illustrating display control processing when the subject has high brightness in the first embodiment. As shown in FIG. 3, the viewfinder field includes a first field area 200 for allowing the user to visually recognize the subject optical image formed on the focus plate 41, and an information display unit adjacent to the lower side of the first field area 200. And a second visual field area 210 that allows the user to visually recognize various information displayed on the screen 43.

  As described above, the camera system control unit 55 performs AF and AE in response to the ON operation of the release button switch SW1. The finder display control unit 134 controls the transmissive display unit 42 to display the focus detection area 201 focused by AF on the first visual field area 200. Further, the finder display control unit 134 controls the information display unit 43 to display the information object 211 indicating the shutter speed, aperture value, and ISO sensitivity obtained by AE in the second visual field area 210.

  When the subject has high brightness, if the information object 211 of the second visual field area 210 is close to the first visual field area 200, the user can display the information indicated by the information object 211 of the second visual field area 210 depending on the glare of the first visual field area 200. It becomes difficult to see. Therefore, the finder display control unit 134 moves the position of the information object 211 in the second visual field area 210 away from the first visual field area 200 when the subject has high luminance.

  In the first embodiment, the photometric sensor 48 detects the luminance distribution of the entire subject even in the photometric mode in which a specific area is metered. The camera system control unit 55 uses the luminance distribution of the entire subject to calculate the EV value of the entire first visual field area 200 indicating the luminance of the entire subject. Then, the camera system control unit 55 determines that the subject has high luminance when the EV value of the entire first visual field region 200 is equal to or greater than the first threshold value. The first threshold value is a lower limit value of the EV value of the entire first visual field region 200 when it becomes difficult for the user to visually recognize the information of the second visual field region 210, and is 12, for example.

In the example of FIG. 3, the user uses the camera 10 to photograph a house having a blue sky and a white wall as a subject. In the scene, sunlight is reflected by the white wall of the house, and the brightness of the white wall area is high. FIG. 3A shows the viewfinder field when the proportion of the blue sky is large and the subject is not bright. In this case, the finder display control unit 134 arranges the information object 211 at the center of the second visual field area 210. As shown in FIG. 3 (a), the upper end of the information object 211 is positioned a distance d ₀ apart downward from the lower end of the first field area 200, and the left end of the information object 211, right from the left end of the finder field A distance D ₀ is arranged in the direction. The distance d ₀ and the distance D ₀ are defined in advance. In the first embodiment, the position shown in FIG. 3A of the information object 211 in the second visual field area 210 is referred to as a standard position.

FIG. 3B shows the viewfinder field when the white wall of the house is large and the subject has high brightness. In this case, the finder display control unit 134 arranges the information object 211 below the second visual field area 210. As shown in FIG. 3 (b), the upper end of the information object 211 is positioned a distance d ₁ apart downward from the lower end of the first field area 200, and the left end of the information object 211, right from the left end of the finder field A distance D ₀ is arranged in the direction. The distance d ₁ is larger than the distance d ₀ and is defined in advance. In the first embodiment, the position shown in FIG. 3B of the information object 211 in the second visual field area 210 is referred to as a far position.

As described above, the finder display control unit 134 moves the information object 211 away from the first visual field region 200 by a distance (d ₁ -d ₀ ) when the subject has high brightness, compared to when the subject does not have high brightness. Therefore, the user can visually recognize the information indicated by the information object 211 even if the first visual field region 200 is dazzling. On the other hand, when the subject is not bright, that is, when the first visual field area 200 is not dazzling, the information object 211 approaches the first visual field area 200. Therefore, the user can easily confirm both the subject in the first visual field area 200 and the information indicated by the information object 211 in the second visual field area 210.

  In the example of FIG. 3B, the finder display control unit 134 performs display control for the luminance of the subject in the entire first visual field region 200. However, even if the luminance of the subject in the entire first visual field region 200 is not high, when the subject in a part of the first visual field region 200 has high luminance, the user can select the second visual field region 210 in the vicinity of the first visual field region 200. May be difficult to see. Therefore, the finder display control unit 134 may execute display control for the luminance of the subject in a specific divided region among the plurality of divided regions into which the first visual field region 200 is divided.

  For example, the camera system control unit 55 uses the luminance distribution of the subject in the adjacent segment area adjacent to the second visual field area 210 among the plurality of segment areas into which the first visual field area 200 is segmented. The EV value of the adjacent segment area indicating the luminance is calculated. Then, the camera system control unit 55 determines that the subject in the adjacent segment area has high brightness when the EV value of the adjacent segment area is equal to or greater than the second threshold value. The second threshold value is a lower limit value of the EV value of the adjacent segment area when it is difficult for the user to visually recognize the information in the second visual field area 210, and is, for example, 12 that is the same as the first threshold value. Note that the second threshold value may be larger than the first threshold value. The finder display control unit 134 moves the position of the information object 211 in the second visual field area 210 away from the adjacent segment area when the subject in the adjacent segment area has high luminance.

FIG. 3C shows the viewfinder field when the ratio of the blue sky and the white wall of the house is the same and the entire subject is not high-luminance, but the area of the white wall of the house is high-luminance. Of the three segmented regions in which the first visual field region 200 is equally divided into three in the vertical direction, the subject in the lower segmental region 202 adjacent to the second visual field region 210 has high brightness. In this case, the finder display control unit 134 arranges the information object 211 below the second visual field area 210 as in the case of FIG. As shown in FIG. 3 (c), the upper end of the information object 211 is positioned a distance d ₁ apart downward from the lower end of the first field area 200, and the left end of the information object 211, right from the left end of the finder field A distance D ₀ is arranged in the direction.

As described above, the viewfinder display control unit 134 moves the information object 211 from the first visual field area 200 when the subject in the adjacent divided area has high luminance, even if the luminance of the subject in the entire first visual field area 200 is not high. (D ₁ -d ₀ ) Keep away. Therefore, the user can visually recognize the information indicated by the information object 211 even if a part of the first visual field area 200 near the second visual field area 210 is dazzling.

  FIG. 4 is a diagram for explaining display control processing when the subject has low luminance in the first embodiment. As the information object 211 in the second visual field area 210 is closer to the first visual field area 200, the user can easily confirm both the subject in the first visual field area 200 and the information indicated by the information object 211 in the second visual field area 210. Therefore, the finder display control unit 134 brings the position of the information object 211 in the second visual field area 210 closer to the first visual field area 200 when the subject has low luminance.

  The camera system control unit 55 calculates the EV value of the entire first visual field region 200 as described above, and determines that the subject has low brightness when the EV value of the entire first visual field region 200 is less than the third threshold value. To do. The third threshold value is an upper limit value of the EV value of the entire first visual field area 200 when the user can visually recognize the information of the second visual field area 210 in the vicinity of the first visual field area 200, for example, 2. The third threshold value is smaller than the above-described first threshold value and second threshold value described with reference to FIG.

  In the example of FIG. 4, the user uses the camera 10 to photograph a house having a blue sky and a black wall as a subject. In this scene, the black wall of the house is shaded, and the brightness of the black wall area is low. FIG. 4A shows the viewfinder field when the proportion of the blue sky is large and the subject is not low-luminance. In this case, the finder display control unit 134 arranges the information object 211 at the same position as in the case of FIG.

FIG. 4B shows the viewfinder field when the ratio of the black wall of the house is large and the subject has low luminance. In this case, the finder display control unit 134 arranges the information object 211 in the upper part of the second visual field area 210. As shown in FIG. 4 (b), the upper end of the information object 211 is positioned a distance d ₂ apart downward from the lower end of the first field area 200, and the left end of the information object 211, right from the left end of the finder field A distance D ₀ is arranged in the direction. The distance d ₂ is the distance d ₀ is a value less than is defined in advance. In the first embodiment, the position shown in FIG. 4B of the information object 211 in the second visual field area 210 is referred to as a vicinity position.

In this way, the finder display control unit 134 moves the information object 211 closer to the distance (d ₀ −d ₂ ) from the first visual field region 200 when the subject has low luminance than when the subject does not have low luminance. Therefore, the user can easily confirm both the subject of the first visual field region 200 and the information indicated by the information object 211 of the second visual field region 210 within the substantially same visual field without a large movement of the line of sight.

  In the example of FIG. 4B, the finder display control unit 134 performs display control for the luminance of the subject in the entire first visual field region 200. However, even if the luminance of the subject in the entire first visual field region 200 is not low, when the subject in a part of the first visual field region 200 has low luminance, the user can select the second visual field region 210 in the vicinity of the first visual field region 200. May be visible. Therefore, the finder display control unit 134 may execute display control for the luminance of the subject in a specific divided region among the plurality of divided regions into which the first visual field region 200 is divided.

  The camera system control unit 55 calculates the EV value of the adjacent segment area as described above, and determines that the subject in the adjacent segment area has low luminance when the EV value of the adjacent segment area is less than the fourth threshold value. The fourth threshold value is an upper limit value of the EV value of the adjacent segment area when the user can visually recognize the information of the second visual field area 210, and is, for example, 2 that is the same as the third threshold value. Note that the fourth threshold value may be smaller than the third threshold value. Then, the finder display control unit 134 brings the position of the information object 211 in the second visual field area 210 closer to the adjacent segment area when the subject in the adjacent segment area has low luminance.

FIG. 4C shows the viewfinder field when the ratio of the blue sky and the black wall of the house is about the same and the entire subject is not low-luminance, but the area of the black wall of the house is low-luminance. Of the three divided areas obtained by dividing the first visual field area 200 into three equal parts in the vertical direction, the subject in the lower divided area 202 adjacent to the second visual field area 210 has low brightness. In this case, the finder display control unit 134 arranges the information object 211 in the upper part of the second visual field area 210 as in the case of FIG. As shown in FIG. 4 (c), the upper end of the information object 211 is positioned a distance d ₂ apart downward from the lower end of the first field area 200, and the left end of the information object 211, right from the left end of the finder field A distance D ₀ is arranged in the direction.

As described above, the viewfinder display control unit 134 moves the information object 211 from the first visual field area 200 when the subject in the adjacent segment area has low luminance even though the luminance of the subject in the first visual field area 200 is not low. (D ₀ -d ₂ ) Therefore, the user can easily confirm both the subject of the first visual field region 200 and the information indicated by the information object 211 of the second visual field region 210 within the substantially same visual field without a large movement of the line of sight.

  FIG. 5 is a flowchart showing the display control process in the first embodiment. This flow starts when the camera system control unit 55 detects a power-on operation of the camera 10. In step S101, the camera system control unit 55 determines whether or not the release button switch SW1 is turned on. The camera system control unit 55 proceeds to step S114 when the switch SW1 is not turned on, and proceeds to step S102 when the switch SW1 is turned on. In step S102, the camera system control unit 55 initializes a built-in timer t to 0 and starts measuring the timer t.

  In step S103, the photometric sensor 48 detects the luminance of the subject as described above and outputs photometric data to the camera system control unit 55. In step S104, as described with reference to FIG. 3, the camera system control unit 55 uses the photometry data to determine whether the luminance of the subject in the entire first visual field area where the subject optical image is observed is high. Judge whether or not. When the camera system control unit 55 determines that the luminance of the subject in the entire first visual field region is high, the process proceeds to step S109, and determines that the luminance of the subject in the entire first visual field region is not high. If so, the process proceeds to step S105.

  In step S105, as described with reference to FIG. 3, the camera system control unit 55 uses the photometric data to increase the luminance of the subject in the adjacent segment area in the first visual field area where the subject optical image is observed. It is determined whether or not the brightness. If the camera system control unit 55 determines that the luminance of the subject in the adjacent segment area is high, the process proceeds to step S109. If the camera system control unit 55 determines that the luminance of the subject in the adjacent segment region is not high, step S106. Migrate to

  In step S106, as described with reference to FIG. 3, the camera system control unit 55 uses the photometric data to determine whether the luminance of the subject in the entire first visual field area where the subject optical image is observed is low. Judge whether or not. If the camera system control unit 55 determines that the luminance of the subject in the entire first visual field region is low, the process proceeds to step S110, and determines that the luminance of the subject in the entire first visual field region is not low. If so, the process proceeds to step S107.

  In step S107, as described with reference to FIG. 3, the camera system control unit 55 uses the photometric data to reduce the luminance of the subject in the adjacent segment area in the first field area where the subject optical image is observed. It is determined whether or not the brightness. When the camera system control unit 55 determines that the luminance of the subject in the adjacent segment area is low, the process proceeds to step S110, and when it determines that the luminance of the subject in the adjacent segment area is not low, step S108.

FIG. 6 is a diagram illustrating a first modification and a second modification of the display control process in the first embodiment. FIG. 6 shows a modification of the far position of the information object 211. In FIG. 6, the standard position of the information object 211 is the position shown in FIG.

FIG. 6A shows a first modification of the display control process in the first embodiment. In the first modification, the finder display control unit 134 changes the display size of the information object 211 in the second visual field area 210 according to the luminance of the subject. Specifically, when the subject has high brightness, the finder display control unit 134 arranges the information object 211 below the second visual field area 210 and reduces the information object 211. As shown in FIG. 6 (a), the upper end of the information object 211 is positioned a distance d ₃ away downward from the lower end of the first field area 200, and the left end of the information object 211, right from the left end of the finder field It is arranged a distance D ₁ apart in the direction.

By making the information object 211 smaller, the distance d ₃ becomes larger than the distance d ₀ and the distance d ₁ described above, and the distance D ₁ becomes larger than the distance D ₀ . The distance _{d 3} and the distance _{D 1} is defined in advance. Note that the display size of the information object 211 in the case of FIG. 6A is the lower limit size when the user can visually recognize the information indicated by the information object 211, and is a value calculated in advance experimentally. As described above, the finder display control unit 134 reduces the display size of the information object 211 when the subject has high brightness, compared to when the subject does not have high brightness. Therefore, when the subject has high luminance, the information object 211 can be further away from the first visual field region 200 than when the display size of the information object 211 is not changed.

  FIG. 6B shows a second modification of the display control process in the first embodiment. In the second modification, the finder display control unit 134 changes the position of the information object 211 in the left-right direction in the second visual field area 210 according to the luminance of the subject. In FIG. 6B, the ratio of the blue sky and the white wall of the house is about the same and the entire subject is not high-intensity, but sunlight reflects off the white wall of the house on the lower left side of the first visual field area 200, and the white The viewfinder field when the wall area is high-intensity is shown. In this case, the subject in the lower left segmented region 203 has high brightness among the nine segmented regions in which the first visual field region 200 is equally divided into three in the vertical direction and three in the horizontal direction. Note that whether or not the subject in the adjacent segment area has high luminance is determined using the second threshold as in the case of FIG.

The finder display control unit 134 moves the position of the information object 211 in the second visual field area 210 away from the adjacent segment area when the subject in the adjacent segment area has high luminance. In the case of FIG. 6B, the finder display control unit 134 arranges the information object 211 in the lower right part of the second visual field area 210. As shown in FIG. 6 (b), the upper end of the information object 211 is positioned a distance d ₁ apart downward from the lower end of the first field area 200, and the left end of the information object 211, right from the left end of the finder field It is located a distance D ₂ away direction. The distance D ₂ is a distance D ₀ value greater than the above are defined in advance.

  As described above, the viewfinder display control unit 134 changes the position of the information object 211 in the left-right direction when the luminance of the subject changes significantly in the left-right direction. Therefore, the information object 211 can be further away from the high brightness area in the first visual field area 200.

  FIG. 7 is a diagram illustrating a third modification of the display control process in the first embodiment. In the third modification, another information display unit having the same configuration as the information display unit 43 is provided in the finder unit 40, and two regions for allowing the user to visually recognize information are formed in the finder field of view.

And a third visual field region 220 that allows the user to visually recognize various types of information. In the third modification, the second visual field area 210 is set larger than the third visual field area 220.

  In the third modification, the finder display control unit 134 switches the display content of the second visual field area 210 and the display content of the third visual field area 220 according to the luminance of the subject. When the subject is not bright, the finder display control unit 134 displays the focus detection area 201 and the information object 211 described above in the first visual field area 200 and the second visual field area 210, respectively, as shown in FIG. . Further, the finder display control unit 134 displays an information object 221 indicating an exposure correction value for correcting an appropriate exposure value in the third visual field region 220.

  In the third modification, the finder display control unit 134 gives priority to the information indicated by the information object 211 over the information indicated by the information object 221. The finder display control unit 134 arranges information indicated by the information object 211 to be prioritized over the second visual field area 210 that is larger than the third visual field area 220 when the subject is not bright. Therefore, the information object 211 can be displayed larger than the information object 221, and the user can easily view the information indicated by the information object 211.

  FIG. 7B corresponds to the scene of FIG. That is, FIG. 7B shows the viewfinder field when the subject in the lower section area 202 has high luminance. In this case, the finder display control unit 134 exchanges the information object 211 and the information object 221. That is, the finder display control unit 134 displays the information object 211 in the third visual field area 220 and displays the information object 221 in the second visual field area 210. Thus, the information object 211 is arranged farther from the lower segment area 202 than when displayed in the second visual field area 210. Therefore, it becomes easy for the user to visually recognize the information of the information object 211 to be prioritized.

  In the third modification, the finder display control unit 134 may change the display sizes of the information object 211 and the information object 221 according to the sizes of the second visual field area 210 and the third visual field area 220. For example, the finder display control unit 134 makes the information object 211 in the third visual field area 220 smaller than when displayed in the second visual field area 210.

  In the third modification, the third visual field region 220 is disposed adjacent to the right side of the first visual field region 200, but the arrangement position is not limited thereto. The third visual field region 220 may be disposed adjacent to the first visual field region 200 at a location different from the second visual field region 210. Further, in the third modification, the camera system control unit 55 may accept a setting from the user as to whether or not to execute the process of switching the display content of the second visual field area 210 and the display content of the third visual field area 220.
