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 2):
The image pickup apparatus according to  claim 1 , further comprising a conversion unit configured to convert the image shift amount into a defocus amount, and a control unit configured to control movement of the focus lens,\n wherein after correcting the defocus amount obtained in the focus detection operation based on the correction amount for the first aperture acquired from the first storage unit and moving the focus lens, the control unit moves the focus lens based on the correction amount of the position of the focus lens by the difference between the first aperture and the second aperture in the image shooting operation.
