ABSTRACT:
A method and apparatus are disclosed for reducing the effects of bleed-through on captured images. Multiple images of a single physical medium are recorded by illuminating the physical medium with at least one light source capable of generating light having a first and a second illumination quality. By combining the recorded images, a captured image with reduced bleed-through may be formed. Reflected light, transmitted light, or a combination of reflected and transmitted light from one or more illumination sources may be used in recording the images. The present invention finds application in photocopy devices, facsimile machines, optical recognition systems, and the like.
