Abstract:
1. An image capturing apparatus comprising: a moving unit configured to move a focus position within a predetermined range by changing a distance in an optical axis direction between a photographing lens and an image sensor; a detection unit configured to detect the focus state of an image obtained from an image sensor; and a defocusing correction unit configured to perform image processing to correct defocusing of the image obtained from the image sensor using the focus state of the image detected by the detection unit during said movement performed by the moving unit, wherein, in a case where the focus state detected by the detection unit indicates that a focus position for an in-focus image is within the range of the motion, the defocusing correction unit performs the image processing based on a difference between the focus position for an in-focus image and a focus position at which the image has been captured during the motion, and wherein, in a case where the focus state detected by the detection unit indicates that the focus state for an in-focus image is beyond the range of the motion, the defocusing correction unit performs the image processing based on a difference between a focus position within the range on a side close to the focus state for an in-focus image and the focus position at which the image has been captured during the motion.
