Abstract
Noise suppression in a solid-state imaging element that detects an address event is disclosed. In one example, a solid-state imaging element includes an illuminance meter, a detection pixel, and a parameter control circuit. The illuminance meter measures illuminance. The detection pixel detects whether or not an amount of change in brightness exceeds a predetermined threshold value. The parameter control circuit controls a parameter of the detection pixel in accordance with the illuminance measured by the illuminance meter.
