Image capture apparatus capable of shifting electrical signal when center of gravity is shifted due to an eclipse of pupil area

摘要

An image capture apparatus comprises an imaging optical system, an image sensor, a pupil division unit which limits a light beam entering each pixel on the image sensor to a specific pupil area of the imaging optical system, an incident angle determination unit which determines an incident angle to each pixel on the image sensor, an image shift unit which shifts an electric signal obtained from the image sensor, based on the incident angle determined by the incident angle determination unit and a position of a plane on which image generation is performed, and an image generation unit which synthesizes electric signals obtained from the image shift unit.
