Abstract
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.
Claims8
An image capturing apparatus comprising:
- an image sensor in which at least part of pixels arranged in two dimensions are configured as focus detection pixels with divided-pupil;
- memory control means configured to read out from a memory position information for the focus detection pixels stored in the memory;
- and
- correction means configured to identify positions of the focus detection pixels in the image sensor based on the position information for the focus detection pixels and to correct a defective focus detection pixel signal using defect-free focus detection pixel signals.
A control method of controlling an image capturing apparatus provided with an image sensor in which at least part of pixels arranged in two dimensions are configured as focus detection pixels with divided-pupil, the control method comprising:
- a read-out step of reading out from a memory position information for the focus detection pixels stored in the memory;
- and
- a correction step of identifying positions of the focus detection pixels in the image sensor based on the position information for the focus detection pixels and correcting a defective focus detection pixel signal using defect-free focus detection pixel signals.
