Abstract
In an embodiment a method for operating a pixel arrangement includes, during an exposure period, accumulating, by a photodetector, in a first integration period, charge carriers, pulsing, at an end of the first integration period, a transfer transistor to a first voltage level for transferring a portion of the accumulated charge carriers to a diffusion node, wherein the portion is configured to be drained to a supply voltage, continuing, by the photodetector, to accumulate, in a second integration period, charge carriers, after the second integration period, pulsing the transfer transistor to a respective further voltage level with at least one additional pulse, wherein, with each additional pulse, an additional portion of the accumulated charge carriers is configured to be drained to the supply voltage, and wherein each additional pulse is followed by an additional continued accumulation of charge carriers in a respective additional integration period with the photodetector.
