CCD vs CMOS

I wrote in Para 3 about CCD vs CMOS cameras and somehow the industrial trend went towards CCD camera. However, it is very much possible to make economical CMOS camera with low power consumption and high resolution. Recently I came across one camera from one of our Chinese companies. I tested their 480 TV lines CMOS camera and found it to be much more effective than 420 TVL CCD camera with very little power consumption.
