Abstract:
An image capturing apparatus comprises: a sensor that photoelectrically converts incidence light and outputs an image signal; a focus control unit that performs focus control based on a contrast of the image signal corresponding to each of a plurality of focus control areas set within an image capturing area; a counting unit that detects and counts, from among the plurality of focus control areas, high luminance focus control areas indicating a luminance of at least a predetermined luminance; and an exposure control unit that performs exposure control, in a case where the counted number is a first number, so as to reduce an exposure amount of the sensor to less than when the counted number is a second number that is smaller than the first number, the exposure control being performed before the focus control by the focus control unit.
