Abstract
The image pickup apparatus includes an image pickup element including first pixels for photoelectrically converting an object image formed by a light flux from an image taking optical system and second pixels for photoelectrically converting optical images formed by light fluxes divided form the light flux from the image taking optical system, and a controller performing focus detection based on a phase difference of the optical images, control of an aperture stop included in the image taking optical system and an image capturing operation for generating a captured image by using signals obtained from the first pixels. The controller increases, when an image capturing aperture size of the aperture stop is smaller than a focus detecting aperture size in a case of performing the focus detection between the image capturing operations in continuous image capturing, the aperture size to the focus detecting aperture size in the focus detection.
