ABSTRACT:
A method and system automatically determines the width (i.e., left and right edges) of a document when it is loaded for scanning or copying. When a document is staged, the scanner collects a predetermined number scanlines of the leadedge of the document. Both first order and second order statistics of the scanner and document are then calculated based on the scanned data. The auto-width detection process is adaptive to CCD sensor output variation, document variation, and scanner variation, thus making it robust against dust in the sensor path and random fluctuations of the scanner.
