摘要：
A hand-supportable automatic digital imaging-based bar code symbol reading device comprises: an automatic object presence detection subsystem; an area-type image formation and detection subsystem having a narrow-area image-capture mode of operation; a LED-based illumination subsystem having narrow-area illumination mode of operation; an image capturing and buffering subsystem; and an image-processing bar code symbol reading subsystem. The automatic object presence detection subsystem automatically detects an object, and the LED-based illumination subsystem automatically illuminates the detected object in a field of narrow-area narrow-band illumination, while the area-type image formation and detection subsystem captures a narrow-area image thereof. The image-processing bar code symbol reading subsystem automatically and directly applies decode image processing operations on the captured image, in an outwardly-directed manner, referenced from the center of the captured narrow-area image, to automatically read a 1D bar code symbol on the detected object.
