Abstract
An image pickup apparatus configured to output an image signal based on an optical signal photoelectrically converted by an image pickup element provided with two-dimensionally arranged pixels includes: a clipper configured to limit output voltage of the image signal based on the optical signal; a gain upper limit setter configured to set a gain upper limit to be applied to the optical signal; a determiner configured to determine whether or not a condition to cause occurrence of a smear in a shot image is satisfied; and a controller configured to limit an output voltage of the optical signal by using the clipper when the determiner determines that the condition to cause occurrence of the smear is satisfied, and to inactivate limitation of the output voltage of the optical signal by using the clipper when the determiner determines that the condition to cause occurrence of the smear is not satisfied.
