Abstract: An imaging element 5 includes an imaging pixel 51 and phase difference detecting pixels 51R and 51L. When there is an instruction to start capturing a moving image, a defocus amount calculating unit 19 determines a shift amount of two output signal groups at the time of performing a correlation operation in accordance with information of an F value, a focal distance, and a focal position. The defocus amount calculating unit 19 shifts two output signal groups by a unit amount within a range of a determined shift amount to perform a correlation operation and calculates a defocus amount from the result. Thereafter, when the distance to a major subject varies, the defocus amount calculating unit changes the shift amount which has been already set to a larger value.

Abstract: According to the present invention, when restoration processing of a taken image by the use of a restoration filter corresponding to a subject distance is performed, by storing only a corresponding restoration filter in a subject distance range between the estimation variation close range and the infinity such that a restoration filter in a range on the nearer side than the estimation variation close range is not provided from the beginning, it is thereby possible to reduce the number of restoration filters held beforehand.

Abstract: One aspect of the present invention thinning-reads pixel signals from the multiple pixels according to a thinning pattern from an image pickup element, or extracts pixel signals from the multiple pixels according to the thinning pattern from a color image that is read from the image pickup element and corresponds to the color filter array, and acquires a thinned color image. Then, moving image data is generated on the basis of the thinned color image. Adoption of the thinned color image as a target image to be subjected to moving image processing can facilitate reduction in processing time per frame, and prevent the frame rate from decreasing. Furthermore, thinning-reading pixels from the image pickup element can facilitate reduction in time of reading an image from the image pickup element.
