Abstract
An image capturing apparatus comprising: an optical element that changes a transmittance of light; an image sensor; an acquisition unit that acquires information regarding a temperature of the optical element; a first control unit that controls a transmittance of the optical element; and a second control unit that controls exposure when a subject is captured using the image sensor and an image signal is output. The first control unit performs control so as to increase a target transmittance of the optical element in a first condition under which a temperature of the optical element exceeds a predetermined temperature, based on the information regarding the temperature, and the second control unit controls exposure excluding the transmittance according to a change in the transmittance of the optical element in the first condition.
