ABSTRACT:
A CCD imager has a line-transfer register the contents of which are transferred at pixel scan rate, one or two lines at a time, through a side-loaded CCD shift register forward clocked at a multiple of pixel scan rate, to an electrometer. Forward clocking the CCD shift register at higher rate than pixel scan rate reduces the differential delay between the various points of side-loading the CCD shift register, so line selection artifacts are confined to the line retrace interval. Line selection artifacts are then suppressed by normal line-retrace-interval blanking.
