发明名称 Image Pickup apparatus and focus control method
摘要 An image pickup apparatus includes an imaging element having a group of AF pixel pairs that realizes a pupil-dividing function and a group of normal pixels without such a pupil-dividing function. The image pickup apparatus performs focus control for driving a focus lens toward an in-focus position detected by phase different AF based on a pixel signal generated from the group of AF pixel pairs when it is determined that the reliability of the phase difference AF is high based on the pixel signal. The image pickup apparatus performs focus control for driving a focus lens in an in-focus direction detected by contrast AF based on a pixel signal generated from the group of normal pixels when it is determined that the reliability of the phase difference AF is low.
