I know that professional Video CCD cameras use (or at least did... I'm somewhat out of touch today) separate chips for each of the two or three colors (RGB) with some type of beam slipper (some used two and used subtractive math to "figure out" the third, I believe). That allowed for smaller chips, since each was only responsible for one color, and then they were superimposed upon each other, like color separations. Would this not work for digital stills, or is the resolution so high they couldn't get registration?
