Abstract

To improve a decay time of an image sensor that has a plurality of light sensor elements and to permit higher image repetition rates, where a first signal level representative of a light intensity is picked up by the light sensor element, the light sensor element is reset and then a resulting second signal level is picked up, an output of the light sensor element is initialized at a signal level, which is selected as a function of the first signal level picked up, before picking up the first signal level again.
