Here's my take on this technology.
First, the technology is very simple. It simply makes the camera act more like the human eye and less like a simple grid. Instead of filtering everything into RGB, this technology filters things into RGBL where L is basically just a clear filter. Now luminance data is provided which is combined with the other data to arrive at your final pixel. Since the clear filter is 200% brighter than a colored filter, more energy is collected and more energy is like a bigger sampling size and due to the law of averages, that produces less signal noise.
But's that approach is not without it's problems.
The signal would only be more accurate in the Luminance domain. It would be less accurate in the color domain. So you're trading color accuracy for luminance accuracy. In low light situations, this is a worthwhile trade.
Also, since you would have to spend die area on clear subpixels, you would lose resolution.
The problem with press releases like this is that they only tell you the positives but none of the negatives.
Foveon's X3 technology is ultimately superior but fabricating a 3d cell structure is hard on semiconductor processes that were made for 2d structures. This Kodak technology is at least easy to implement (although that's only because it is not really a technological advance at all).
