Abstract

An image sensor includes a plurality of image elements configured to provide associated image element signals which are dependent on light intensities incident on the image elements. The image sensor includes an accumulation circuit with a plurality of charge storage elements, wherein the accumulation circuit is configured to change charges on the charge storage elements during a phase in dependence on image element signals of respectively associated image elements. The accumulation circuit is further configured to change an association between charge storage elements and associated image elements in successive phases, so that in operation, a charge on one of the charge storage elements depends on image element signals of plural image elements in a plurality of phases.
