摘要
A digital scanning system for scanning a document includes a full width array having two sets of color sensitive photosites, each set of photosites being sensitive to a different color of light and a backdrop portion. The backdrop portion is colored such that the backdrop portion appears nearly black to one set of color sensitive photosites and appears nearly white to a different set of color sensitive photosites. the scanning system further includes a light source, a document edge detection circuit operatively connected to the set of color sensitive photosites which perceive the backdrop portion as being nearly black, and an image processing circuit operatively connected to the set of color sensitive photosites which perceive the backdrop portion as being nearly white.
