Automatic digital-imaging based bar code symbol reading system supporting a pass-through mode of system operation using automatic object direction detection and illumination control, and video image capture and processing techniques

摘要

An automatic digital-imaging based code symbol reading system supporting a presentation mode of system operation, automatic object direction detection and illumination control, and video image capture and processing techniques. By virtue of the present invention, the automatic digital-imaging based code symbol reading system ensures the reliable reading of code symbols graphically represented in digital images, in high-throughput point-of-sale and other environments.
