You had a good run of reasonableness there but you seem to have gone quite wrong. It gives UP TO 20MP full color images (that is unique color per pixel) which is UP TO 40MP bayer equivalent.

Because many, many of the colors can be determined uniquely they are still full color. In the end the question is the percentage of pixels that can generally be determined uniquely.

Yes, you can get "up to" 20 MP of perfect color just as you can, with a Bayer CFA (without AA filter) can get "up to" 20 MP perfect color - if you are lucky.

The Bayer sensor may get lucky guesses, but it can never KNOW the correct color values. Because the bayer sensor has to guess for many many values, it is mostly wrong. Not wrong by much, but wrong.

Maybe that's a good way of phrasing it, the Quattro can only know the "true" color on a 5mp level but never on a 19mp level. Whereas the Merrill can know true color on a 14.7mp level.

The Quattro sensor can know with absolute certainly in many cases the exact colors for every pixel in each quad. So there's a high likelihood it is mostly right.
