1. A scanning device comprising: a scanning mechanism to scan an image fixed on a medium to generate a digital infrared representation of the image and a digital visible light representation of the image; a processing mechanism to substantially reduce effects of noise and distortions within the digital visible light representation of the image in one pass, the processing mechanism at least decorrelating visible light aspects from the infrared representation of the image and employing a one-pass filter that uses both the infrared and the visible light representations of the image.
