3-CCD/CMOS cameras are equipped with three image sensors, one each for blue, red and green—three of the colors separated by a prism. A thicker glass block than that used in a single CCD/CMOS camera is arranged between the lens and the sensor. When the same lenses as those for single CCD/CMOS cameras are used for 3-CCD/CMOS cameras, the camera performance may not be fully achieved due to the optical effect of color separation within the camera. That is why special lenses are needed for 3-CCD/CMOS cameras.
