Abstract
Image capturing apparatuses having an exposure control unit configured to execute exposure control by changing at least one of parameters of an aperture value, an accumulation period of a charge in an image sensor, and an amplification amount of a signal output by the image sensor; and a generation unit configured to generate aperture control information related to a change in the aperture value in the exposure control are included. In a case where an aperture value is changed in accordance with a luminance change of an object, the generation unit generates the aperture control information with which, with respect to a specific aperture value which is settable, an actual aperture value discretely changes. In the case where an aperture value is changed in accordance with the luminance change of the object, on the basis of the aperture control information, the exposure control unit discretely changes the aperture value.
