Abstract
Miniaturization of pixels is facilitated in a solid-state imaging element that detects presence or absence of an address event. The solid-state imaging element includes a plurality of detection pixels and a detection circuit. In the solid-state imaging element including the plurality of detection pixels and the detection circuit, each of the plurality of detection pixels generates a voltage signal according to a logarithmic value of a photocurrent. Furthermore, in the solid-state imaging element including the plurality of detection pixels and the detection circuit, the detection circuit detects whether or not a change amount of a voltage signal of a detection pixel indicated by an input selection signal among the plurality of detection pixels exceeds a predetermined threshold value.
