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.

Abstract: According to the present invention, the first and second phase difference pixels are arranged on the pixel lines in the first direction in the color image that is thinned during imaging of a moving image including that for live view display. Therefore, even during moving image taking, phase difference AF can be accurately performed. Furthermore, the pixel values at the pixel positions of the first and second phase difference pixels in the thinned color image can be accurately acquired on the basis of the pixel values of the surrounding pixels. Accordingly, reduction in the image quality of the taken image (still image or moving image) due to the phase difference pixels can be prevented or alleviated. Furthermore, the pixel values can be accurately acquired on the basis of the pixel values of the surrounding pixels during simultaneous processing.
