Abstract
An automatic code symbol reading system for use in point of sale (POS) environments, employing automatic object motion detection and illumination control, and digital video image capturing and processing 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 versatility required to accommodate the different ways in which human operators present objects for code symbol reading at POS environments.
