Abstract:
A hand-supportable digital imaging-based bar code symbol reading device comprises: an IR-based object presence and range detection subsystem; a multi-mode area-type image formation and detection 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 automatic light exposure measurement and illumination control subsystem; an image capturing and buffering subsystem; a multi-mode image-processing bar code symbol reading subsystem; an input/output subsystem; a manually-activatable trigger switch; and a system control subsystem integrated with each of the above-described subsystems. The digital imaging-based bar code reading device employs a multi-mode bar code symbol reading image processor that is dynamically reconfigurable in response to real-time image analysis carried out upon captured narrow and wide area images.
