Hi Robert
I think that when you see the term Bayer, it usually translates to INFERIOR resolution compared to black & white.
If I understand correctly, all ccds are B&W and to obtain one-shot colour, 4 pixels are "grouped" together to capture R, G & B (via micro-lenses) to then form the final colour image.
I think that CMOS may be different, although still suffers from inferior resolution due to the chip or circuit design in an attempt to obtain one shot colour.
That's about all I recall on the topic.
