Abstract (en)
[origin: WO9207441A1] A large area scanning system (10) for use in scanning very large documents includes a table (12) and scanning mechanism (16) on which is located a scanner head (14). The scanner head includes an illumination mechanism and a camera for receiving light reflected from a document on the table. The scanning system (10) is characterized by a controller (18) which initially scans the document in a series of strips (106) and generates therefrom reformatted data in the form of a sequence of scan lines. To increase operating speed, the controller (18) provides for data compression with bilevel data.
