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.
