摘要

The invention relates to a pixel cell (100; pixel), comprising an output (102), a photosensor (110; sensor), which is configured to generate a first measuring current (I_DPh1) in a first measurement cycle (τ_c) and a second measuring current (I_DPh2) in a second measurement cycle (τ_c) as a function of radiation, an output node (104), a power storage device (120; SI-Mem), which is configured so that in a first operating mode a current (I_M1) can be injected by the power storage device (120) as a function of the first measuring current (I_DPh1), and so that in a second operating mode the power storage device (120) is configured to hold the injected current (I_M1) so that the injected current can be detected at the output node (104), and a switching unit (130; IO), which is configured to form a difference between the injected current (I_M1) and the second measuring current (I_DPh2) at the output node in a reading cycle and couple the output node (104) to the output (102).
