Abstract
The horizontal transfer register of a CCD image sensor has a final stage electrode which is independent of other electrodes of the horizontal transfer register. To eliminate flickering in a video picture, the operation of the horizontal transfer register is stopped for a given period of time during which field shifting is effected. The final stage electrode is driven by continuous pulses even when the operation of the horizontal transfer register is stopped during field shifting, thereby eliminating black level variations from an image sensor output.
