Abstract

A significant feature of electronic scanning is the ability to manipulate images. This ability is necessarily coupled with the ability to locate particular images or portions on the document as it is scanned by an imager on a platen or driven past an imager by a pair of pinch rollers with a constant velocity transport (CVT). This feature is well known, and is sometimes used for calibration of scanning devices.
