In order to obtain a reference output from which density nonuniformity and fixed pattern noise are removed using OB pixels in a solid-state image pickup device, a solid-state image pickup device which has a plurality of storage units for storing pixel signals output from a plurality of photoelectric conversion elements, which are formed on a single semiconductor substrate and at least two of which are shielded from light, in correspondence with the photoelectric conversion elements. Pixel signal outputs from the shielded photoelectric conversion elements are subjected to averaging processing on the storage units. Also, in the solid-state image pickup device, the storage units are formed of capacitances, which are electrically and temporarily connected to each other to attain the averaging processing.
