Abstract
An image capture apparatus comprising a plurality of pixels, each pixel having a light-receiving circuit that outputs a pulse signal in response to incidence of a photon and a counting circuit configured to count the pulse signal, is disclosed. The image capture apparatus further comprises a detection circuit that detects whether or not a flickering light source is present in a field of view, based on an output frequency of the pulse signal.
