Abstract
To reduce a circuit scale in a solid-state image sensor that detects an address event. The solid-state image sensor includes a pixel array unit and a drive circuit. In the solid-state image sensor, in the pixel array unit, a logarithmic response pixel that outputs an analog signal proportional to a logarithmic value of an incident light amount and a detection pixel that detects whether or not a change amount of the incident light amount has exceeded a predetermined threshold and outputs a detection signal indicating a detection result are arrayed. Furthermore, in the solid-state image sensor, the drive circuit drives the logarithmic response pixel and the detection pixel to output the analog signal and the detection signal.
