A document image scanner; a camera having a field of view, for sensing
differentiated information areas on each physical document as the
physical document is transported; an image processing system associated
with the camera, for producing a virtual image data file from the
differentiated information areas sensed by the camera; sensors for
determining the position of the physical document relative to the camera
field of view; of electro-mechanical devices for actuating the
transporter; and a data interface controller for receiving data from the
sensors and controlling the electro-mechanical devices. A communications
link is provided between the data interface controller and the image
processing system for synchronization by the data interface controller,
of the physical document as conveyed and the virtual document image
captured by the image processing system.
