ABSTRACT:
As CCD circuit for restoring to a common DC level, data received from a plurality of detector channels of a scanned array so as to overcome the effect of variations in detector parameters and other non-uniformities in the circuit. The DC correction value is established during retrace time by storing a representative time integrated data charge packet when energy from a cold reference surface is being applied to the detectors. During the scan time of the field of view by the detectors the representative charge packet is utilized to provide a DC restoration or correction charge to each data charge packet received from the detectors. The system thus standardizes to a common DC level, the output data from a plurality of channels.
