Abstract:
An image pickup apparatus corrects defocusing caused by an aperture difference to prevent degradation in AF focusing accuracy. In the image pickup apparatus, an image shift amount is detected based on a pair of picture signals by a phase difference AF method. When a first aperture at a time of a focus detection operation for detecting an image shift amount by a focus detection unit differs from a second aperture at a time of an image shooting operation for recording an image signal acquired from an image pickup device, a correction amount of a position of a focus lens due to a difference between a first aperture and a second aperture is calculated, by using a correction amount acquired from a first storage unit and a difference in the position of the focus lens between the first aperture and the second aperture acquired from a second storage unit.

Claim (Index 3):
The image pickup apparatus according to  claim 1 , wherein the first storage unit stores the correction amount according to at least one of a zoom lens position, an image height of an image pickup surface, and a distance to a subject.
