1. A method for improved barcode decoding, comprising the steps of: sending a command to create a captured image of a target region; obtaining a copy of said captured image; scaling said captured image by a predetermined value to form a scaled image; locating at least two coordinates defining a region of interest in said scaled image; calculating a corresponding region of interest in said captured image based on the region of interest in said scaled image; and sending a command to decode just said corresponding region of interest.
