ABSTRACT:
Radiation illuminating the A register of a charge-coupled device (CCD) imager of the field transfer type during the transfer of a field from A to the B register results in smear in the reproduced image. Such smear is reduced by removing any charge which may be present in the A register, during a period which begins just after the transfer of a field from the A to the B register, and which terminates when the integration of the next field begins.
