Abstract:
1. A method for multi-pass scanning a document comprising: mechanically translating a document at a first speed for a first pass within a defined path in a document scanner for a first scan; mechanically translating said document at a second speed for a second pass within said defined path in the document scanner for a second scan; mechanically translating said document at a third speed for a third pass within said defined path in the document scanner for recording an image of a surface of said document when illuminated with a first light condition; and mechanically translating said document at a fourth speed for a fourth pass within said defined path in the document scanner for recording a second image of the surface of said document when illuminated with a second light condition, wherein said document scanner utilizes higher speeds during the first and second passes as compared to the third and the fourth pass.
