For intelligent traffic systems, VGA resolution CCD-based cameras have traditionally been the accepted technology, but with the quality of CMOS image sensors continuously improving, CMOS-based cameras are now a viable option for demanding license plate recognition applications.\u00a0 The latest system requirements are for higher resolution (HDTV) and frame rates of 30 to 60 frames per second as well as all of the following: color, NIR sensitivity, high dynamic range, and low noise at high gain.\u00a0 Imaging systems for traffic are exposed to extreme lighting and temperature conditions which affect the image quality.\u00a0 So what are the advantages and disadvantages of choosing a camera based on a CMOS image sensor versus a CCD image sensor?<\/p>\n
