ABSTRACT:
An improved operational blooming control circuit for a charge coupled device image sensing array in which the "accumulated" regions of the substrate are driven into "depletion" at the end of the integration time and prior to the transfer of the contents of the A to the B registers. This is found to improve the resolution of the reproduced image.
