ABSTRACT:
An image sensor array (12) is comprised of a plurality of sensor elements (60) arranged in rows (62) and columns (64). Each element (60) is operable to modulate an output voltage signal responsive to charge accumulating in its gate region (70) responsive to incident light. Circuitry (74, 84, 78, 72) is provided to obtain and store a signal that is related to a threshold voltage differential produced by the accumulated charge, and not to the intrinsic threshold voltages or sizes of sensors (60). The array (12) has automatic blooming control, and can exhibit electronic iris, zooming and panning functions.
