Abstract
To suppress occurrence of a delay in detection of a valid address event to be originally detected. An image pickup element includes a plurality of pixels (), a pixel address event detection unit (), a region address event detection unit (), and a pixel selection unit (). The pixel () includes a photoelectric conversion unit () that performs photoelectric conversion of incident light. The pixel address event detection unit () is arranged in each pixel and detects a pixel address event that is an address event of a pixel itself. The pixel address event is detected based on a change amount of charge generated by the photoelectric conversion. The region address event detection unit () detects a region address event that is an address event in a predetermined region. The region address event is detected based on a change in a charge amount generated by the photoelectric conversion in a plurality of pixels in the predetermined region among the plurality of pixels. The pixel selection unit () selects the pixel () based on the detected pixel address event and region address event, and causes the selected pixel to output a detection result of the pixel address event.
