Symbol scanning system and method having adaptive pattern generation

摘要

A system for scanning a symbol that has a plurality of modes including a learning mode and an adaptive mode. When the scanner is in a learning mode, a plurality of scans are generated using a plurality of sets of operating parameters. A decoder decodes the plurality of scans generated by the scanner. A data collector collects readability data indicating whether the generated scan decodes successfully or unsuccessfully for each of the sets of operating parameters. A processor determines whether the readability data is acceptable for each of the sets of operating parameters. An optimal set of operating parameters is selected from the acceptable sets of operating parameters. The optimal set of operating parameters is stored along with data identifying the symbol so that the optimal set of operating parameters may be recalled for use in scanning symbols of a similar type or in a similar environment.
