Yes, Bruce. But did you read the imaging-resource article? "Unlike Olympus' approach, which grabs 8 frames and uses a half-pixel shift between two groups of four to interpolate additional pixels, Ricoh's method uses just four shots, to bring the four pixels of each Bayer color filter array cell into alignment with each other. The resulting file has the same number of pixels as conventional shots, but each pixel contains full, uninterpolated RGB data. (Reminiscent in that sense of Sigma's Foveon sensors.)"
