SOLID-STATE IMAGE PICKUP DEVICE AND CONTROL METHOD THEREOF, AND CAMERA |
摘要 |
An object of the invention is to cause a part of charge spilling from a photoelectric conversion unit to flow into a charge holding unit and thereby extend dynamic range and at the same time improve image quality. There is provided a solid-state image pickup device having a pixel including: a photoelectric conversion unit generating and accumulating charge by means of photoelectric conversion; a first 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.
