CCD cameras are the most common type of camera found in industrial
applications. This is due to a number of factors including the length of
time CCD technology has been available (over 25years) and some technical
advantages over CMOS. Generally speaking, CCD sensors result in very high
quality images due to the low noise, high fill factor and good
signal-to-noise ratio. However, CMOS sensor technology has improved
dramatically over recent years which means there is a 'real' choice now
between CCD cameras and CMOS cameras. Which technology you should use
depends on your application.

'Applications' comparisons guide:
High-Speed/High-Resolution (ie 1megapixel at 500fps) - CMOS
Highest Image Quality - CCD
Imaging highly reflective objects - CMOS
Multiple regions of interest (on sensor) - CMOS
Lowlight or very short exposure times - CCD |
