  • CCD circuitry for line-sequential read out of a photosensor array
    Patent number: 4679090
    Abstract: Diagonally disposed line-selection artifacts appear in the video signal from a CCD imager using a line-transfer register, owing to differential delay in a side-loaded CCD shift register used for transferring charge packets from the image sensing array to the charge sensing output stage. The extent of these line-selection artifacts is shortened in the direction of line scan by spatial multiplexing, so they occur entirely within line retrace intervals. The line-selection artifacts are then suppressed by normal line retrace blanking.
