Patent attributes
A solid-state imaging device including a plurality of two-dimensionally arranged pixels is provided. The pixels each include a light receiving circuit that senses incident light having arrived at the light receiving element in a light exposure period, a counter circuit that counts the number of arrivals of the incident light based on the light reception signal from the light receiving circuit, a comparison circuit that outputs a comparison signal according to the count from the counter circuit, and a storage circuit that stores a time signal as a distance signal when the comparison signal from the comparison circuit is ON. Transistors included in the light receiving circuit, the counter circuit, the comparison circuit, and the storage circuit have the same conductivity type.
