After a little more research regarding the Sigma camera referenced above I have come up with the following:
It appears that this new Sigma camera will employ an updated "Foveon" sensor which was first introduced in 2002 and then improved in '04.
With standard sensors such as the CCD and CMOS, which appear in other digital cameras, each pixel can capture only one color. The cameras logic goes through some algorithms in an attempt to interpret what is the real color. This method will come up with some amount of color artifacts and image blurring. With the Foveon sensor there are three colors per pixel: red, green and blue. It is written that this is pretty much the 'holy grail' of digital image sensors. It should mean ultra sharp, detailed images with full color single pixel resolution. At least that is the claim.
