Solid-state imaging element and imaging device

The signal quality of a solid-state imaging element configured to detect address events is enhanced. The solid-state imaging element has open pixels and light-blocked pixels arrayed therein. In the solid-state imaging element, the open pixels each detect whether or not an amount of change in incident light amount exceeds a predetermined threshold, and output a detection signal indicating a result of the detection. On the other hand, in the solid-state imaging element, the light-blocked pixels each output a correction signal based on an amount of noise generated in the open pixels each configured to detect whether or not an amount of change in incident light amount exceeds the predetermined threshold and to output a detection signal indicating a result of the detection.
