摘要

A pixel cell, and a method of use thereof, the pixel cell including: an output, a photosensor configured to generate a first measuring current in a first measurement cycle and a second measuring current in a second measurement cycle as a function of radiation, an output node, a power storage device configured so that in a first operating mode a current can be injected by the power storage device as a function of the first measuring current, and so that in a second operating mode the power storage device is configured to hold the injected current so that the injected current can be detected at the output node, and a switching unit configured to form a difference between the injected current and the second measuring current at the output node in a reading cycle and to couple the output node to the output.
