The reason why 3 CCDs is b

The reason why 3 CCDs is better than 1 CCD is because with 3, each CCD only has to capture one of the 3 primary colors; red, green and blue. With 1 CCD, that CCD is in charge of capture all the colors at once, and as a result it’s less than great color reproduction.

CMOS sensors, on the other hand, are used in many digital SLR cameras and seem to do a pretty good job. And those DSLR cameras only have 1 CMOS. I think you would be in good shape going to a camera with 1 CMOS sensor. I would assume 3 CMOS sensors is better than 1 CMOS sensor of course.
