The brightness of the surrounding environment is detected by a brightness detection unit provided in a camera. The contents of settings of the camera are displayed on a sub-display 18 in a situation in which the surrounding environment is bright. The contents of settings of the camera and an image representing the set state of a shutter speed dial 33 are displayed on the sub-display 18 in a case in which the surrounding environment is dark. ## Claims ### Claim 1 A camera comprising: a camera body including a first surface, a second surface facing the first surface, and a third surface crossing the first surface and the second surface; a lens mount configured to have a lens mounted thereon, the lens mount being disposed on the first surface side; a rotary dial operable to set a value of imaging; a first display configured to display a live view image, the first display being disposed on the second surface side; a second display configured to display the value that is set by the rotary dial, the second display being disposed on the third surface side, the second display including a display surface having a normal that is perpendicular to the display surface of the second display and is nonparallel to an optical axis of the camera; and a system controller configured to control a display of the second display, wherein in a case in which a lens is mounted on the lens mount, the system controller changes a brightness of the second display in accordance with a brightness of an imaging light incident on the camera through the lens. ### Claim 2 (depends on 1) The camera according to claim 1, wherein the rotary dial is disposed on the third surface side, and wherein the second display and the rotary dial are disposed on a same side with respect to the optical axis of the camera, in a view from the third surface side. ### Claim 3 (depends on 1) The camera according to claim 1, wherein the system controller changes only the brightness of the second display in accordance with the brightness of the imaging light to raise a visibility of the second display. ### Claim 4 (depends on 1) The camera according to claim 1, wherein the value of imaging is a shutter speed, and wherein the system controller raises a visibility of the value of the shutter speed on the second display after the rotary dial is operated. ### Claim 5 (depends on 1) The camera according to claim 1, wherein the system controller changes the brightness of the second display in stages based on a plurality of threshold values with respect to the brightness of the imaging light. ### Claim 6 (depends on 1) The camera according to claim 1, wherein the system controller is a microcomputer. ### Claim 7 (depends on 1) The camera according to claim 1, wherein the brightness of the imaging light is detected based on a brightness of image data obtained by imaging of the imaging light. ### Claim 8 (depends on 7) The camera according to claim 7, further comprising: a lens mounted on the lens mount. ### Claim 9 (depends on 1) The camera according to claim 1, wherein the camera is a non-reflex digital camera. ### Claim 10 (depends on 1) The camera according to claim 1, wherein the first display is a variable-angle display, and wherein the first display is movable with respect the second surface side in a direction toward and away from the third surface side. ### Claim 11 (depends on 2) The camera according to claim 2, further comprising: a lens mounted on the lens mount. ### Claim 12 (depends on 1) The camera according to claim 1, further comprising: a lens mounted on the lens mount. ### Claim 13 (depends on 3) The camera according to claim 3, further comprising: a lens mounted on the lens mount. ### Claim 14 (depends on 4) The camera according to claim 4, further comprising: a lens mounted on the lens mount. ### Claim 15 (depends on 1) The camera according to claim 1, wherein the system controller changes only the brightness of the second display in stages based on a plurality of threshold values with respect to the brightness of the imaging light. ### Claim 16 (depends on 15) The camera according to claim 15 further comprising: a lens mounted on the lens mount. ### Claim 17 (depends on 16) The camera according to claim 16, wherein the camera is a non-reflex digital camera. ### Claim 18 (depends on 1) The camera according to claim 1, wherein a brightness of the third surface is presumed in accordance with the brightness of the imaging light. ### Claim 19 (depends on 1) The camera according to claim 1, wherein the normal of the display surface of the second display is perpendicular to the optical axis of the camera. ### Claim 20 (depends on 1) The camera according to claim 1, wherein the second display is configured not to display the live view image.
