Publication number: 20230228875Abstract: In a solid-state imaging element that measures a distance, a circuit scale is reduced. The solid-state imaging element includes a pulse signal generation section and an up-down counter. The pulse signal generation section is provided with an avalanche photodiode that converts incident light including reflected light of irradiation light radiated during a predetermined light-on period into a photocurrent and multiplies the photocurrent and a quench circuit that generates a pulse signal on the basis of the multiplied photocurrent. The up-down counter performs one of up counting and down counting each time the pulse signal is generated during the light-on period, and performs another of the up counting and the down counting each time the pulse signal is generated during a light-off period that does not correspond to the light-on period.Type: ApplicationFiled: February 26, 2021Publication date: July 20, 2023Inventors: KEI NAKAGAWA, KATSUHIKO HANZAWA, TAKAO TANIKAME
