Zusammenfassung:	An active pixel sensor cell array in which a partial transimpedance amplifier amplifies the output of each cell. The pixel sensor cell array comprises a plurality of pixel sensor cells and a second part of the amplifier. Each pixel sensor cell comprises a photo-sensitive element, a capacitor and a first part of an amplifier. The capacitor is coupled between a terminal of the photo-sensitive element and an output line of the cell. The capacitor is operable to provide a capacitive feedback in the pixel sensor cell. The second part of the amplifier is coupled to the output lines of a plurality of pixel sensor cells. The amplifier is configured to amplify an output signal from a cell.
