A variably responsive photosensor comprising a plurality of photosensitive regions, a first one of the photosensitive regions being connectable to a first potential source and a signal collection means characterised in that the variably responsive photosensor further comprises a switching means adapted for switching the remaining photosensitive regions between the first potential and a second potential being lower than the first potential; and further adapted for reversibly connecting the remaining photosensitive regions to the signal collection means. |
