Abstract
A detection circuit configured to detect whether an event has occurred based on whether an amount of change in an amount of incident light exceeds a predetermined threshold and a counting circuit configured to count the number of incident photons within a predetermined exposure period are included. A mode control circuit controls a first switch configured to switch between a first mode in which a photodiode and the detection circuit are connected to each other and a second mode in which the photodiode and the counting circuit are connected to each other.
