Solid-state imaging device, electronic device, and distance measurement system

Abstract

A solid-state imaging device, an electronic device, and a distance measurement system for miniaturization of pixels in a device that outputs a luminance signal and an event signal. A device includes: a pixel array unit in which an event pixel that detects that a luminance change exceeds a predetermined threshold and a gradation pixel that outputs a luminance signal of a gradation level according to a light amount of incident light are mixed, in which a color filter of the same color is formed in units of two or more pixels in the gradation pixel, and the event pixel is disposed with a region size in which at least two of the gradation pixels are arranged in a row direction or a column direction. The present disclosure can be applied to, for example, a distance measurement system or the like that generates image information and distance measurement information.
