Abstract
An automatic digital imaging-based code symbol reading system supporting a presentation-type mode of system operation, a multi-tier modular software architecture, automatic 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 1D and/or 2D code symbols graphically represented in digital images captured in demanding point-of-sale and other environments.
