发明名称 IMAGE PICKUP APPARATUS AND FOCUSING METHOD
摘要 An image pickup apparatus includes an image pickup element that includes a plurality of image pickup pixels and a plurality of focus detecting pixels, a detector configured to detect a phase difference between two images of the object on a secondary imaging plane, and a controller configured to provide focusing based on a defocus amount obtained from a detection result of the detector for a first focus detecting point, and set a correcting value used to correct a defocus amount obtained from a next detection result of the detector so that a difference can reduce between the defocus amount obtained from the detection result of the detector for the first focus detecting point and a defocus amount obtained from the focus detecting pixels for the first focus detecting point of a captured image of the object that has been captured.
