摘要： An image pickup device, wherein a part of the carriers overflowing from the photoelectric conversion unit for a period of photoelectrically generating and accumulating the carriers may be flowed into the floating diffusion region, and a pixel signal generating unit generating a pixel signal according to the carriers stored in the photoelectric conversion unit and the carriers having overflowed into the floating diffusion region, is provided. The expansion of a dynamic range and the improvement of an image quality can be provided by controlling a ratio of the carriers flowing into the floating diffusion region to the carriers overflowing from such a photoelectric conversion unit at high accuracy.

摘要： 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.

摘要： A solid state image pickup device that can properly widen a dynamic range is provided. Carriers that have overflowed from photodiodes (1003a to 1003c) to lateral overflow regions (1010a to 1010c) and carriers accumulated in the photodiodes (1003a and 1003b) are transferred to FD regions (1005a to 1005c). Signals based on those carriers are added and held in a signal level holding capacitor (Cs) and read out therefrom, thereby widening the dynamic range.
