Photodetection element and electronic device

Abstract

Erroneous event detection caused by crosstalk is to be suppressed in a case where a pixel that detects an event and a pixel that outputs gradation information coexist. A photodetection element, which includes a plurality of pixel groups in which each of the plurality of pixel groups includes a first pixel and a first pixel circuit that output a pixel signal corresponding to a light amount of incident light, a second pixel that detects a change amount of the light amount of the incident light, and a second pixel circuit that compares the change amount detected by the second pixel with a bias signal to detect an event, includes a correction signal generation circuit that generates a correction signal for offsetting crosstalk in which the pixel signal affects the detection of the event, and a bias correction circuit that generates a bias correction signal obtained by correcting the bias signal on the basis of the correction signal, in which the second pixel circuit compares the change amount of the light amount of the incident light with the bias correction signal to detect the event.
