A charge-coupled device (64) is exposed to color portions of an image (61), thereby generating charge packets in the array (64) of photosensitive storage regions. The charge packets stored in a first set of horizontal rows of photosensitive regions are then moved into a second set of horizontal rows, remaining in the array for subsequent exposures. These exposing and moving steps are then repeated. 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 exposure stored in a single photosensitive storage region in a first proportion representative of a luminance signal.
