ABSTRACT:
A charge-coupled device is exposed to a color portion of an image, thereby generating charge packets in the array of photosensitive storage regions. The charge packets stored in a first set of horizontal rows of photosensitive storage regions are then moved into a second set of horizontal rows of photosensitive storage regions, remaining in the array for subsequent exposures. These exposing and moving steps are repeated for each color exposure in excess of two. Charge packets from each successive exposure are combined in the array in a predetermined manner with charge packets from previous exposures. Finally, the charge-coupled device is exposed to a final color portion of the image, thereby generating final charge packets in the array. Selected ones of the final charge packets comprise charge from more than one photosensitive storage region and from more than one exposure stored in a single photosensitive storage region. A first subset of the selected final charge packets each comprises charge corresponding to different exposures in a first proportion. The first proportion is representative of a luminance signal.
