ABSTRACT:
A system for performing short wavelength imaging with a broadband illumination source includes an image processor that receives signals from a color image sensor. The image processor reduces the contribution of red illumination light to an image by computing blue, green, and blue-green (cyan) color components of display pixels from the signals received from the image sensor. The blue, green, and cyan color component values are coupled to inputs of a color monitor for display to produce a false color image of the tissue.
