Abstract
A high-quality image is taken by a solid-state imaging element that detects an address event. The solid-state imaging element is provided with a pixel array unit and an analog-to-digital conversion unit. In the pixel array unit in the solid-state imaging element, a normal pixel that generates an analog signal by photoelectric conversion of incident light and outputs the analog signal and a detection pixel that detects that an amount of change in incident light becomes larger than a predetermined threshold and outputs a detection result are arranged. Furthermore, the analog-to-digital conversion unit converts the analog signal into a digital signal.
