摘要 |
Method of and apparatus for processing captured images within a semi-automatic hand-supportable imaging-based bar code symbol reader in order to read 1D and/or 2D bar code symbols graphically represented therein. The semi-automatic hand-supportable digital imaging-based bar code symbol reader comprises: an automatic object presence 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 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 bar code symbol reader embodies advanced image processing methods for reading 1D and/or 2D bar code symbols graphically represented in captured digital images.
