ABSTRACT:
A system electronically registers an image on an input document. The system includes a scanner for generating an image data stream representing an electronic image of the image on the input document and an edge detecting circuit for detecting edge data within the image data stream. A circuit calculates a skew angle of the input document based on the detected edge data and rotates the electronic image based on the calculated skew angle to register the electronic image with an output medium. The system also includes a non-image area generating circuit for generating areas in the electronic image which correspond to non-image areas based on the calculated skew and detected edge data. The skew calculation, rotation operation and the non-image area generation is based the electronic detection of the corners and center of the leading edge of the document being scanned.
