Zusammenfassung:To improve image quality of image data in a solid-state image sensor that detects an address event. The solid-state image sensor includes a photodiode, a pixel signal generation unit, and a detection unit. In the solid-state image sensor, the photodiode generates electrons and holes by photoelectric conversion. The pixel signal generation unit generates a pixel signal having a voltage according to an amount of one of the electrons and the holes. The detection unit detects whether or not a change amount in the other of the electrons and the holes has exceeded a predetermined threshold and outputs a detection signal.
