ABSTRACT:
The present disclosure relates to a method for automatically scaling an image, comprising initially scanning an original image at an initial scanning resolution, detecting the relative positions of lateral edges of the original image, determining the width of the original image based upon the positions of the lateral edges, making an initial size presumption of the original image based upon the determined width, making a first scanning resolution determination based upon the initial size presumption, and continuing scanning of the original image based upon the first scanning resolution determination.
