Abstract
A method and apparatus employs a weighted order stored in a weight table for automatically discriminating optical symbols which may be encoded in any one of at least two symbologies. The weighted order may be dynamically updated to reflect the distribution of symbologies as the symbols are acquired and decoded.
Claims4
A symbol reader for reading and decoding symbols, reader comprising:
- an optical source configured to illuminate a symbol with an optical beam;
- an optical receiver configured to receive the optical beam after the optical beam is reflected from the symbol and to produce a set of data corresponding to the reflected optical beam;
- a memory including a set of weighted average information related to a weighted order for attempting to decode the symbols;
- and
- a microprocessor in operational communication with the optical receiver and the memory, the microprocessor responsive to the weighted average information to apply a series of translations to the set of data in the weighted order which corresponds to the weighted average information.
