Claim:
1. An image capturing apparatus comprising: an image sensor in which a plurality of light receiving elements are arrayed with respect to one lens on an image sensing plane on which an object image is formed by an imaging lens, the lens being arranged such that an exit pupil of the imaging lens and the light receiving elements are in a conjugate relationship; a polarizer arranged at approximately a position of the exit pupil of the imaging lens, and having a plurality of areas that have different polarization directions corresponding to a plurality of different areas of the exit pupil; and at least one processor or circuit configured to perform the operations of the following units: an image processing unit that generates a plurality of images corresponding to the plurality of areas of the polarized from output of the in plurality of light receiving elements; and a compositing unit that divides each of the plurality of images into a plurality of block areas, obtains polarization information for each block area by comparing images of corresponding block areas in the plurality of images, and composites the plurality of mages based on the obtained polarization information for each block area.
