Abstract
An imaging apparatus includes a photometric sensor, and can continuously acquire a plurality of images by a single imaging operation. A CPU for image processing and an arithmetic operation acquires image data output by a photometric sensor and performs photometric processing. The CPU determines presence or absence of a flicker light source using a plurality of pieces of acquired image data, and calculates a motion vector of an object by comparison of image data. If it is determined that there is a flicker light source in a photographing environment, gain adjustment is performed on the basis of a result of flicker detection so as to have a brightness of an image suitable for detection of a motion vector, and the motion vector is calculated using image data after gain adjustment.
