Title: Solid-state image pickup device and control method thereof, and camera

Abstract: A solid-state image pickup device having a pixel includes a photoelectric conversion unit generating and accumulating charge by photoelectric conversion; a charge holding unit being shielded from light, and being adaptable to accumulate a part of charge spilling from the photoelectric conversion unit in a period during which the photoelectric conversion unit generates and accumulates charge; an amplifying unit (SF-MOS) amplifying charge; a first transfer unit (Tx-MOS) transferring the charge accumulated in the photoelectric conversion unit to the amplifying unit; and a second transfer unit (Ty-MOS) transferring the charge accumulated in the first charge holding unit to the amplifying unit. A part of charge spilling from the photoelectric conversion unit is caused to flow into the charge holding unit and thereby extend the dynamic range, and at the same time, improve image quality.
