Claim:
1. A display control apparatus that controls a display image displayed on a display device, provided in an image capturing device, for visually identifying a subject, the apparatus comprising: an input unit to which an output of a captured image obtained by shooting is input; a brightness detection unit for detecting brightness of a shot subject on the basis of an input of the output of the captured image; a stability brightness calculation unit for calculating stability brightness obtained by modifying a temporal change in the brightness of the subject to a slower temporal change on the basis of a change in the brightness of the subject detected by the brightness detection unit; and a display brightness control unit for controlling a following speed of a change in the brightness of the display image with respect to the change in the brightness of the subject on the basis of the calculated stability brightness so that an amount of time of the change in the brightness related to the display image becomes longer than an amount of time of the change in the brightness of the subject, wherein the display brightness control unit defines, as a brightness adjustment value, an amount of change in the stability brightness until the stability brightness catches up with the change in the brightness of the subject, and performs a control such that the stability brightness catches up with the change in the brightness of the subject while decreasing the brightness adjustment value.
