ABSTRACT:
A method and apparatus for multi-threaded operation of an image-based symbology reader is provided. In the method of the invention, acquired images of an encoded symbol are attempted to be decoded using a plurality of decoding engines asynchronously and substantially simultaneously in a multi-threaded processing environment. Each of the decoding engines can be directed to a specific symbology type to achieve an improved response time when reading multiple symbol types.
