摘要： An image pickup apparatus in which, a taking lens is installable or fixed, includes an image pickup element in which, pixels having a photoelectric conversion portion are arranged two dimensionally. The pixels include focal-point detection pixels which are arranged to restrict a direction of incidence of a light beam which is incident, and image-pickup pixels which are arranged such that, the direction of incidence of the light beam which is incident is not restricted more than the direction of incidence restricted by the focal-point detection pixel.The focal-point detection pixel outputs at least a signal for ranging, and the image-pickup pixel outputs at least a signal for an image.The image pickup apparatus includes an overflow judging section which judges whether or not the photoelectric conversion portion has overflowed, and a calculating section which calculates an amount of defocus based on a judgment result of the overflow judging section and the signal for ranging.
