ABSTRACT:
A system for scanning and digitizing printed documents for subsequent storage, retrieval and manipulation. Documents are continuously transported across the focal plane of a stationary scanner, and are repetitively scanned in a single axis. In a preferred embodiment, two scanners are employed to permit scanning and digitization of both sides of a particular document in a single pass through the transport mechanism. Circuitry is included in the scanner which permits the presence or absence of a document to be detected and allows dynamic adjustment of threshold levels, thereby accomodating documents which utilize shaded backgrounds.
