How Color Cameras Work
•1 CCD
cameras
–A Bayer pattern is placed in front of the
CCD
–A Demosaicing process reads the pixels in a
region and computes color and intensity
•3 CCD
camera use a beam splitter and 3 separate CCDs
–higher
color fidelity
–needs
lots of light
–requires careful alignment of ccds
