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.

This disclosure describes an aerial vehicle that includes a light alteration assembly that may be used to alter light entering a lens of a camera of the aerial vehicle. The light alteration assembly may include an adjustable visor and/or filters that may be selectively positioned over the lens of the camera. By altering light entering the lens of a camera of the aerial vehicle, the camera is able to obtain higher quality images of the area surrounding the aerial vehicle. The higher quality images may then be processed to accurately detect objects within a vicinity of the aerial vehicle.
