CMOS cameras find a niche
In applications that demand high speed and high dynamic ranges, CMOS cameras can outshine their CCD counterparts.
While CCDs remain the imager of choice for high-fidelity image capture, CMOS imagers present the system developer with a number of advantages, such as digital readout, on-chip programmability, and region-of-interest (ROI) image processing. Thus, while CCD imagers remain dominant in many machine-vision systems, CMOS imagers are gradually carving niche markets in low-cost consumer cameras, as well as in applications where high speed and high dynamic ranges are required.
