Abstract
A hand-supportable digital imaging-based bar code symbol reading system comprises: an automatic object presence and range detection subsystem; an image formation and detection subsystem; a multi-mode LED-based illumination subsystem having an LED illumination array; an automatic light exposure measurement and illumination control subsystem; an image capturing and buffering subsystem; a multi-mode image-processing bar code symbol reading subsystem having a first mode and a second mode of operation; an input/output subsystem; and a system control subsystem for controlling the subsystems. The multi-mode image-processing bar code symbol reading subsystem automatically switches its modes of image-processing during a single bar code symbol reading cycle, and within each mode of image-processing based bar code symbol reading a different image-processing based bar code symbol reading methodology is automatically applied.
