Abstract: The present invention provides a method for automatically cropping a scanned image having irregular boundaries. A pattern sheet is provided on the bottom surface side of the cover of the optical scanner. The pattern sheet is defined by multiple pattern units for serving as referential coordinates.

Then, compare each document block with its correspondent pattern unit to determine if the document block contains AOI data.
