Can ClearType-ish techniques be applied to 3D AA?

I'd like to see a normal digital camera using Foveon CCD. Although Sigma SD9 is not as expensive as other Pro-DSLRs, but it is still too expensive for most people (including me ).

Regarding to the alternative patterns, I think it would be good for digital cameras to use such patterns on their back LCDs.

This isn't true of all digital cameras, but close. Check out the Foveon CCD used in the Sigma SD9. While the Sigma implementation seems lacking, future products based on Foveon technology should be interesting.

Yes, and both Canon and Nikon uses (used in Canon's case) a CYGM pattern in some cameras, but 97% of all digital cameras use a variant of the Bayer RGBG pattern.

*shrugs* I have never thought FoveOn technology was that hot, at least it won't be until conventional 30Mp sensors are common and cheap. The reason is twofold: Quality and process technology. The layering of the sensors leads to lower sensitivity in the lower layers, and this has also been seen in the reviews -- the inner layer (which is R) is very very noisy. This isn't likely to be solvable. Another issue is the process -- the three megapixel FoveOn sensor contains nine million capture elements. I'd rather take a conventional nine million RGBG sensor in this case; lower color fidelity and less sharp edges, yes, but better resolution -- and I'll take detail resolution over "color trueness" any day.

When sensor resolution gets so high that the individual "cexels" ;-) gets too small to be practically useful, it is probably a good idea to switch to FoveOn technology. But that is at least two-three years away, methinks.
