This invention is a solid-state image pickup device that solves the problem of limited dynamic range in the high luminance region in an image sensor having white pixels. White pixels or yellow pixels and at least red pixels, green pixels or blue pixels are arranged in array form on the light receiving surface of a semiconductor substrate. White pixels or yellow pixels have an additional capacitance CS connected to the photodiode via the floating diffusion, a capacitance coupling transistor S that can couple or separate the floating diffusion and the additional capacitance. The proportion of white or yellow pixels to the total number of pixels is higher in a central portion of the light receiving surface than a peripheral portion. The white or yellow pixel may share a floating diffusion with a red, green or blue pixel.
