CCD sensors, by and large, have better image quality and noise characteristics: http://www.dalsa.com/corp/markets/CCD_vs_CMOS.aspx http://www.circuitstoday.com/charge-coupled-devices-ccd-vs-cmos-active-pixel-sensor-aps http://www.electronicsweekly.com/Articles/2005/12/01/37062/cmos-vs.-ccd-and-the-winner-is.htm CMOS sensors have other advantages, though, so the decision to use one technology or the other in a camera sensor is not very clear cut.
