ABSTRACT:
An apparatus for interpolating pixels using correlated dual sample-hold processing for detecting and removing dark current occurring during the feed through period to thereby improve the resolution of a 3-panel type video camera includes first and second composite delay elements for selectively delaying respective ones of signals corresponding to R, G and B channels to permit selected delay of a pair of the signals by 1/2 pitch delays of 1/3 pitch delays during interlacing for interpolating pixels. A method for signal processing using selected pitch delay values is also disclosed.
