FF vs the roughly 4/3" of the DP-1.

More on the Foveon sensor. Here's what Dave Coffin, the author of dcraw, 
the conversion engine underneath many RAW converters has to say:

"The Foveon X3 Capture chip requires a different kind of interpolation. 
Unlike CCD arrays, it captures three colors at every pixel location. But 
the colors are not well separated, so the raw data looks very gray. Much 
processing is needed to enhance color while suppressing noise."
