FOCUS DETECTING APPARATUS, IMAGE PICKUP APPARATUS, FOCUS DETECTING METHOD, AND STORAGE MEDIUM

원문 (중국어)

Focus detecting apparatuses, imaging pickup apparatuses, focus detecting methods, and storage mediums are provided herein. One or more focus detecting apparatuses include one or more processors that operate to perform a first focus detection using a signal from a first focus detecting pixel group in an image sensor having a plurality of focus detecting pixel groups configured to receive light beams passing through different pupil regions in an imaging optical system, and a second focus detection using a signal from a second focus detecting pixel group having a pupil division direction different from that of the first focus detecting pixel group, set a selected area from an area in which a plurality of focus detections are performed, and select a first defocus amount of an object based on a result of using defocus amounts acquired by the first focus detection and the second focus detection in the selected area.
