A sensor including an image pickup element provided with arrangement of a plurality of pixels, each including a plurality of photoelectric conversion portions in a depth direction of a semiconductor, outputs each color component from the same pixel position so that the color components are not extracted separately but extracted as a component different from an ordinary color signal, and this causes an image quality deterioration. The sensor of the present invention, however, is arranged to perform color correction of the signals of the plurality of pixels output from the image pickup element by using different color correction coefficients, respectively, thereby obtaining a high quality image, and to perform appropriate color correction corresponding to color temperature by discriminating an appropriate color correction coefficient to be used for the color correction in accordance with the color temperature detected by an external color temperature sensor at the time of photographing.
