IMAGE PICKUP APPARATUS AND IMAGE PICKUP SYSTEM

摘要

An image pickup apparatus, comprising a point image intensity distribution generating unit configured to generate a point image intensity distribution based on lens light field data and a sensor light-receiving intensity characteristic, the lens light field data including information relating to directions of a plurality of light fluxes emitted from one point of an object position and passing through different regions of an exit pupil of an imaging optical system; and information relating to positions of points on the plurality of light fluxes, the sensor light-receiving intensity characteristic representing light-receiving intensities, which are determined on a light receiving surface of an image pickup element, of light fluxes passing through respective regions of an entrance pupil of a microlens arranged over the image pickup element.
