Abstract
A photoelectric conversion apparatus includes a plurality of pixels including an effective pixel configured to receive light and an optical black pixel shielded from light, determination means for determining a correction value for correcting a signal value of the effective pixel based on a signal acquired from the optical black pixel, and output means for outputting an image using the correction value. The determination means determines the correction value based on a difference between a first signal value indicating a signal value of the optical black pixel in a state where a light-shielding portion is inserted in an optical path of an imaging optical system and a second signal value indicating a signal value of the effective pixel and a third signal value indicating a signal value of the optical black pixel in a state where the light-shielding portion is removed from the optical path of the imaging optical system.
