Patent ID: 8097858

Claim:
An apparatus comprising: an imaging unit configured to perform imaging by using a plurality of image capture elements for accumulating electric charges; a storage unit configured to store a first image to be acquired by driving the image capture elements without causing the image capture elements to receive light, before imaging is performed by causing the image capture elements to receive light: an acquisition unit configured to acquire a second offset image to be acquired by driving a smaller number of image capture elements than a number of image capture elements to be driven when the first image is acquired without causing the smaller number of image capture elements to receive light, according to imaging by causing the plurality of image capture elements to receive light; a generation unit configured to generate an offset correction image to be used for correcting an image to be acquired by causing the plurality of image capture elements to receive light by combining the first image and the second image with a factor according to imaging information on the imaging by causing the plurality of image capture elements to receive light.
