Abstract
A solid-state image pickup device includes a pixel unit in which a plurality of photoelectric conversion elements having different sensitivities are arranged; and a pixel reading unit configured to read and add output signals from the plurality of photoelectric conversion elements in the pixel unit, and to obtain an output signal seemingly from one pixel. The pixel unit includes an absorbing unit configured to absorb overflowing electric charge from a photoelectric conversion element with a high sensitivity.
