Abstract
An image capturing apparatus comprises a plurality of light-receiving circuits, each outputting a pulse signal in response to a photon being incident; a plurality of counter circuits that count the respective pulse signals output by the plurality of light-receiving circuits; and a correction circuit that corrects counts from the plurality of counter circuits and outputs the corrected counts as image data. The correction circuit calculates a correction coefficient on the basis of counts obtained by the plurality of counter circuits in a state where pulse widths of the pulse signals differ or under conditions where generation frequencies of the pulse signals differ, and performs the correction using the correction coefficient.
