An image capturing apparatus includes: an image sensor in which multiple 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 the exit pupil of the imaging lens and the light receiving elements are in a conjugate relationship; a polarizer arranged at approximately the position of the exit pupil of the imaging lens, and having multiple areas that have different polarization directions corresponding to different areas of the exit pupil; and an image processing unit that generates multiple images corresponding to the areas of the polarizer from output of the light receiving elements.
