A single imaging-chip based camera has that imaging chip processing all three primary colors (Red Green Blue).
A 3-imaging chip based camera has one chip per primary color working together.
I intentionally did not specify CCD/3CCD vs CMOS/3CMOS. There are some camcorders available that use CCD technology and some that use CMOS technology.
In each case, there's a lot to read that we do not have space to re-hash here...
In the consumer camcorder space, I *think* Panasonic has the line on -chip camcorders, but they are at the higher end of the line. In the "prosumer" space (usually Sony), their HDR-FX7 and HDR-FX1000 are great for their large 3-chip imaging systems combined with the large lenses.
Some say CMOS is not as good as CCD...
Why are 3CCD camcorders better than the single CCD ones ? Can someone explain in simple terms what each of these terms mean and why should I take one or the other.
