Abstract
An automatic digital video-imaging based code symbol reading system for use in point of sale (POS) environments, employing automatic object motion detection and illumination control, and digital video-imaging based code symbol reading techniques, which ensures the reliable reading of code symbols graphically represented in digital images, in high-throughput point-of-sale and other environments, while providing the versatility required to accommodate the different ways in which operators present objects for code symbol reading at POS environments.
