Claim:
1. An image pickup apparatus configured to perform a reconstruction for a first image so as to generate a plurality of second images having a plurality of focus positions different from each other, the image pickup apparatus comprising: an imaging optical system; an image pickup element including a plurality of pixels configured to obtain the first image; a pupil divider configured so that a ray from the same position of an object plane enters pixels of the image pickup element different from each other in accordance with a pupil region of the imaging optical system through which the ray passes; a focus adjusting portion configured to adjust an imaging position of the imaging optical system; and an image processing portion configured to perform the reconstruction using image pickup condition information of the first image for the first image obtained by the image pickup element so as to generate the second image, wherein the focus adjusting portion is configured to perform a first focus adjustment that adjusts an imaging position of the imaging optical system for a reference object, and a second focus adjustment that moves the imaging position of the imaging optical system for a main object so as to improve a resolution of the main object in accordance with a shift amount of pixels that are to be combined by the reconstruction, and wherein the shift amount of pixels is a shift amount of overlap pixels which are projected on a plurality of virtual imaging planes corresponding to the plurality of focus positions.
