Abstract
An image capturing apparatus includes an image sensor that controls an exposure time for each of a plurality of areas and sets an exposure time, based on luminance information for each of the plurality of areas in an image captured by the image sensor, and one or more processors that execute instructions comprising determining whether an autofocus mode for adjusting a focus position of an imaging optical system using a contrast evaluation value within an evaluation frame set for the image is enabled, wherein the exposure time is determined for each of the plurality of areas so that, within the evaluation frame, a variance of exposure times of the plurality of areas in a case where the autofocus mode is enabled is smaller than a variance of exposure times of the plurality of areas in a case where the autofocus mode is disabled.
