HYBRID SYSTEM AND METHOD FOR READING INDICIA

摘要

An indicia-reading system is provided that incorporates a hybrid approach to decoding indicia such as barcodes. An indicia-capturing subsystem acquires information about indicia within the indicia-capturing subsystem's field of view. An indicia-decoding module decodes indicia information acquired by the indicia-capturing subsystem. The indicia-decoding module includes a primary, basic signal processor for initially decoding indicia information, and a secondary, advanced signal processor for decoding indicia information that is not decoded by the primary, basic signal processor.

1. An indicia-reading system, comprising:
an indicia-capturing subsystem for acquiring information about an indicia within the indicia-capturing subsystem's field of view; and an indicia-decoding module configured for decoding the indicia information acquired by the indicia-capturing subsystem, the indicia-decoding module comprising (i) a primary, basic signal processor for initially processing the indicia information for decoding and (ii) a secondary, advanced signal processor for processing the indicia information for decoding if the primary, basic signal processor does not successfully decode the indicia information; wherein the secondary, advanced signal processor is configured for executing a more complex signal-processing algorithm than the primary, basic signal processor.
