Abstract
A light measurement processing unit controls the driving of a light measurement sensor in a plurality of drive modes. The light measurement processing unit performs light measurement calculation of obtaining the brightness of a subject when a first drive mode is set and calculation of detecting flicker of a photographed scene when a second drive mode is set. Furthermore, the light measurement processing unit performs calculation of detecting a motion vector of the subject between images of continuous frames in the first drive mode. A camera control unit determines a shutter speed by limiting a speed on a high speed side as compared to when flicker is not detected at the time of panning in light exposure control, when flicker is detected at the time of panning on the basis of the calculation result of the light measurement processing unit.
