Claim Text:
1. An image pickup apparatus comprising: an image pickup element including a reference region, a plurality of first image pickup pixel portions that perform a photoelectric conversion and a plurality of second pixel portions that are formed so that an opening region of a photoelectric conversion area corresponding to a microlens for the second pixel portion is smaller than an opening region of a photoelectric conversion area corresponding to a microlens for the first image pickup pixel portion; and a signal processor configured to perform a shading correction for a pixel signal from the image pickup element, wherein, in an output mode, the image pickup element generates and outputs a first pixel signal by combining signals from the plurality of first image pickup pixel portions, and generates and outputs a second pixel signal without combining a signal from the second pixel portions, and wherein, in the output mode, the signal processor performs a first correction for the first pixel signal and the second pixel signal using shading correction data based on a pixel signal from the reference region, and performs a second correction only for the second pixel signal using additional shading correction data different from the shading correction data in the first correction.
