Abstract:
1. An image capturing apparatus comprising: an image capturing unit configured to capture an image by driving a plurality of image sensor pixels; a generation unit configured to generate an exposure period map by assigning, to each of the plurality of image sensor pixels, exposure control information to control a charge accumulation time, based on preliminary captured image data obtained by preliminary image capturing using said image capturing unit, the exposure control information including first exposure control information corresponding to a first accumulation time and second exposure control information corresponding to an accumulation time longer than the first exposure control information; a correction unit configured to expand a first region having the first exposure control information on the exposure period map; and a control unit configured to control the accumulation time for each of the plurality of image sensor pixels in accordance with the exposure period map corrected by said correction unit, wherein said image capturing unit performs main capturing in accordance with the accumulation time controlled by said control unit.
