Abstract
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.
