Abstract: 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.

Abstract: 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.
