Claim of US Patent No. 9,083,877

1. An image processing apparatus that processes an image signal from an image pickup element including a plurality of pixels
for one microlens, the image processing apparatus comprising:
a saturation detector configured to detect whether an output value of each of the plurality of pixels reaches a saturation
level; and

a saturation corrector configured to correct, when an output value of a part of the plurality of pixels reaches the saturation
level, an output value of a saturation pixel that reaches the saturation level and an output value of an adjacent pixel that
shares the same microlens with the saturation pixel and does not reach the saturation level.
