Abstract:
1. A camera system for photographing a subject, the camera system comprising: an imaging optical system configured to form an optical image of the subject; an imaging unit configured to convert the optical image into an image signal, and obtain an image of the subject; an image recording unit configured to store the image signal into a memory; a movable reflecting mirror configured to be in a first state of being positioned in an optical path extending from the imaging optical system to the imaging unit or in a second state of being retracted from the optical path; a reflecting mirror drive unit configured to drive the reflecting mirror; an aperture adjustment unit configured to adjust an aperture value of the imaging optical system; an aperture value input unit to which an aperture value for an aperture of the imaging optical system can be input; a display unit configured to display the image; an image adjustment unit configured to adjust a brightness of the image displayed on the display unit according to the aperture value; a release button for starting the photographing of the subject; and a control unit, wherein: the imaging unit performs focusing by detecting contrast in the image of the subject, and while the reflective mirror drive unit keeps the reflecting mirror in the second state, the image adjustment unit increases the brightness of the image displayed on the display unit when the aperture adjustment unit changes the aperture value of the imaging optical system to a larger aperture value input by the aperture value input unit, and by operation of the release button, the imaging unit performs the focusing, and then the photographing of the subject is started.
