CCD image sensor vs CMOS sensor

i noticed on the canon camera has cmos platform and the nikon has the ccd platform.is there any disadvantage or advantage on have the cmos sensor.or is the ccd sensor better the the cmos.

Its about cost of manufacture and power consumption. Have you seen a full frame digital (35mm) slr w/ ccd yet. Nikon's D2X is a CMOS sensor. All Canon's DSLR are CMOS.

Not exactly true...the 1D is a CCD.

That's why pictures out of camera are so awesome without processing, but then it sucks in high ISO's.

Ok all Canon DSLR that is still in production are CMOS.

Well if we really want to be picky so is DCS1&3 and D2000 &D6000

I guess maybe we're getting off topic here...I think the op (nd I) would like to know some of the technical advantages instead of which cameras they're used in..

The CMOS chip has 2 mongo advantages. 1) You can Fab them on an old memory of logic line. 2) Point defects are less likley to wipe out a full colum or the chip.

Against, is that every pixel has its own noise, bias and gain that you need to calibrate for. The other problem is reset noise, but Canon have that one pretty well licked.

CCDs are quite flexible in how they are operated, and can be extremly acurate and stable. If you want high speed and high acuracy, that can cost in power, plus the clocking of the 3 phase clock arrays is a power pig. But it is a trade off by the designer. The Australia Telescope CCD package runs on under 1W. The CHFT in its original form sank about 1KW into the CCD package.

If you have a semi fab in place, 1 kills the rest stone cold dead. It means that you get you chips for less than free, as you can continue using the fab and don't have to spend many millions pulling it apart and getting rid of it.
