Abstract:
Erroneous detection caused by flicker is suppressed in a solid-state imaging element that detects an address event.
solid-state imaging element includes a plurality of pixels, a current detection unit, and a threshold control unit. In the solid-state imaging element, each of the plurality of pixels compares an amount of change in a voltage corresponding to a photocurrent with a predetermined threshold. Further, the current detection unit detects a sum of the photocurrents of the respective plurality of pixels as a total current. Further, the threshold control unit controls the predetermined threshold to a value corresponding to the total current detected by the current detection unit.
