Abstract
A pixel addition processing unit 35 adds pupil division pixel signals with a plurality of different addition patterns in pupil units to generate a pixel addition image for each addition pattern. Further, the pixel addition processing unit 35 may use a pupil division pixel signal in which a sensitivity difference between pupil division pixels has been corrected, and the addition pattern may be set on the basis of image characteristic information calculated by using the pupil division pixel signal. A super-resolution processing unit 36 performs super-resolution processing using a pixel addition image signal generated for each addition pattern by the pixel addition processing unit 35 to generate an image signal with a higher resolution than that of the pixel addition image signal. A high-resolution image can be generated using pupil division.
