Abstract

The present disclosure relates to an image-capturing system (100) comprising: an image sensor (101) configured to capture images of a scene at a periodic rate; an illumination source (102) for illuminating the scene; measurement and control circuitry (108) configured to: continuously measure a current (200) to/from the image sensor (101); continuously detect periodically alternating high and low levels (202; 203) of the measured current (200); and control the illumination source (102) to alternate between an on state and an off state with an illumination frequency equal to a switching frequency of the detected periodically alternating high and low levels (202; 203) of the measured current (200) such that the illumination source (102) is in the on state during exposure of the image sensor (101). The disclosure further relates to a method (300) of controlling an illumination source for illuminating a scene during image sensor exposures.
