Abstract:
1. A camera, comprising: a taking lens forming an image from light of a subject and including a diaphragm unit limiting luminous flux which passes through the taking lens; an image pickup unit converting the image formed by the taking lens into an electric signal; a subject brightness acquisition unit acquiring brightness information of the subject on the basis of output of the image pickup unit; a control unit controlling exposure according to the brightness information acquired by the subject brightness acquisition unit, and controlling the diaphragm unit; a position detection unit detecting a position of a focus adjustment lens group of the taking lens; and a storage unit storing the position of the focus adjustment lens group detected by the position detection unit when the subject brightness acquisition unit acquires the brightness information, wherein the control unit determines whether or not the brightness information is to be acquired again by the subject brightness acquisition unit on the basis of (i) the current position of the focus adjustment lens group detected by the position detection unit and (ii) the position of the focus adjustment lens group detected by the position detection unit when the subject brightness acquisition unit previously acquired the brightness information and stored in the storage unit, by
