Abstract
A method for expediting the barcode interpretation process implemented on conventional optical imaging barcode readers. The method involves interrupting the mainline processing of the conventional barcode detection, obtaining a copy of the captured image, scaling the image, locating the barcode in the scaled image, scaling the image back to normal proportions, calculating the location of the barcode in the scaled up image, and reporting the barcode location back to the mainline processing for decoding of only the region of interest. The mainline processing of the optical imager may then proceed with barcode interpretation in the area identified by the method of the present invention without wasting time applying complicated decoding algorithms to areas within the image that do not contain any barcode information.
