Basic principles of image sensors
Comparison of CCDs and CMOSs
The main comparison criteria are listed below, and are in constant evolution...
Fill factor
Saturation exposure
Dark current
-
CMOS is not suitable for a long exposition time.
Pattern Noise
-
With CMOSs, correcting a mistake after having shaded the pixels is possible.
Linear defect
-
CMOS non-linear with a receipted flow.
