Abstract: A projection image pickup device includes a pulsed-light emitter, an optical sensor, a reference timing generator that generates a signal indicating an operation reference timing, a controller, and a signal processor. The signal processor sets a differential signal between an output signal from the optical sensor in the second exposure period and an output signal from the optical sensor in the first exposure period as a first differential signal, sets a differential signal between an output signal from the optical sensor in the third exposure period and the output signal from the optical sensor in the first exposure period as a second differential signal, and outputs the sum total of at least two differential signals including the first differential signal and the second differential signal.

Abstract: 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.

Abstract: A distance measurement device includes: a pulse light emitter that emits pulse light to a measurement target; an optical sensor that receives reflected light which is the pulse light reflected by the measurement target; and a controller that controls a light emission timing of the pulse light emitted by the pulse light emitter, and determines a distance to the measurement target, from a light reception timing of the reflected light detected by the optical sensor. The controller sets the light emission timing in each of N periods (N being a natural number less than K) selected randomly from continuous K periods (K being a natural number greater than or equal to 2) to a timing that is delayed by a random first time from a start time of the period.
