Abstract
A pixel cell comprises a plurality of pixels, each pixel comprising a photodiode, a readout circuit comprising a first readout component and a second readout component, wherein a first group of the pixels is configured to detect electromagnetic radiation in a first wavelength range, a second group of the pixels is configured to detect electromagnetic radiation in a second wavelength range, the first readout component is connected with the first group of pixels, the second readout component is connected with the second group of pixels, the first wavelength range is different from the second wavelength range, and the second readout component comprises a plurality of storage capacitors, wherein each pixel of the second group of pixels is assigned to at least one of the storage capacitors, or the second readout component comprises a memory element. Furthermore, a method for operating a pixel cell is provided.
