CCD Vs CMOS:
CMOS sensors are already superior to CCD sensors. The major difference between both sensors is CCD sensor create images with low noise while CMOS tend to be higher in noise. This does not mean that they are inferior to CCD in any respect. CMOS sensors are already superior to CCD sensors in terms of Power consumption. CMOS sensors have made major strides in recent years in two important parameters for area and line scan cameras, namely image rate and noise level. One of the striking feature of vision sensors is sensitivity CMOS sensors.
Advantage of CMOS Sensors
Though CCD sensors has made covered the history of vision but from last couple of years CMOS sensors become more and more popular. Not all CMOS sensors are same some have large dynamic range. CMOS sensors provide High Frame rate, High resolution, Low power consumption, Improved noise performance, Improved quantum efficiency with strong dynamic performance and good price/performance ratio. A strong advantage for CMOS technology is that it provides digital output and can be controlled at the pixel level in ways that are not possible with CCDs.
