Image capturing apparatus and control method therefor

摘要

An image capturing apparatus includes an image sensor 104 in which at least part of pixels arranged in two dimensions are configured as focus detection pixels with divided-pupil, a memory control circuit 113 configured to read out from a memory position information for the focus detection pixels 401, 402 stored in the memory, and a correction circuit 110 configured to identify positions of the focus detection pixels 401, 402 in the image sensor 104 based on the position information for the focus detection pixels 401, 402 and to correct a defective focus detection pixel signal using defect-free focus detection pixel signals.
