Abstract
A CCD such as a frame transfer CCD has an extended dynamic range. The image built up in the image regionin each integration period is transferred to the store regionin each frame transfer period, for example, at a TV signal rate. The dynamic range is increased by dividing the integration period into two parts, and clipping the signal in the first part, but not in the second. The signal is clipped by pulsing the clock electrodes of the image region so as to combine the charges from adjacent wells together, overspill being drained into the anti-blooming structure, consequently reducing well capacity.
