摘要

A hand-supportable semi-automatic Digital Imaging-Based Bar Code Symbol Reading Device comprises: a Multi-Mode Area-type Image Formation and Detection (IFD) Subsystem having narrow-area and wide area image capture modes of operation; a Multi-Mode LED-based Illumination Subsystem having narrow-area and wide area illumination modes of operation; an Image Capturing and Buffering Subsystem; a Multi-Mode Image-Processing Bar Code Symbol Reading Subsystem; a manually-activatable trigger switch. The LED-based illumination subsystem automatically illuminates a target object in a narrow-area field of illumination while the multi-mode IFD subsystem captures a narrow-area image of an aligned 1D bar code symbol thereon, and when manually switched into a wide-area illumination and image capture mode by the trigger switch, the LED-based illumination subsystem illuminates the target object in a wide-area field of illumination, while the multi-mode IFD subsystem captures a wide-area image of randomly-oriented 1D or 2D code symbols thereon.
