Abstract:
An image pickup apparatus, including: an image pickup element configured to photoelectrically convert an object image; a signal acquisition unit configured to acquire a first signal obtained from a light flux that has passed through a first pupil partial region, a second signal obtained from a light flux that has passed through a second pupil partial region, and a third signal obtained from one of a light flux that has passed through a region that includes the first pupil partial region and is wider than the first pupil partial region, and a light flux that has passed through a region that includes the second pupil partial region and is wider than the second pupil partial region; and a defocus state detection unit configured to detect a defocus state based on at least one of the first signal and the second signal, and the third signal.
