Abstract
A document imaging system detects skew and/or size of a document. In one embodiment, a document imaging system generates scanning signals representing the documents, analyxes the scanning signals to detect one more edges of the document before the entire lenght of the document is scanned, establishes a skew angle between the detected edges and a reference orientation, and modifies the scanning signals to compensate for skew while the document is being scanned. In another embodiment, a document imaging system detects one or more edges of a document, defines a polygon having sides substantially congruent with the detected edges, and establishes the size of the document in response to the polygon.
