Abstract
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.
Claims15
1-20. (canceled)
An indicia-reading method, comprising:
- acquiring information about indicia;
- and
- decoding the indicia information, wherein decoding the indicia comprises:
- attempting to decode the indicia using a first program;
- determining that the attempt to decode the indicia fails;
- transmitting pre-processed indicia information, determined during the processing of the indicia using the first program, to a second program;
- and
- decoding the indicia using at least the pre-processed indicia information by the second program.
An indica-reading system comprising:
- an indicia-capturing subsystem for acquiring information about indicia within the indicia-capturing subsystem's field of view;
- and
- an indicia decoder configured for decoding indicia information acquired by the indicia-capturing subsystem, the indicia decoder configured to:
- attempt to decode the indicia using a first program;
- determine that the first program failed to decode the indica;
- transmit a pre-processed indica information from the first program to a second program;
- and
- decode the indica using at least pre-processed indica information by the second program.
A computer program product comprising a non-transitory computer usable medium having control logic stored therein for causing a computer to facilitate reading of an indica, the computer program product is configured to:
- acquire information about an indica;
- and
- decode indica information, wherein the computer program product configured to decode the indica decoding comprises:
- attempting to decode the indicia using a first program;
- determining that the attempt to decode the indicia fails;
- in response to determining that the attempt to decode the indica has failed, transmitting pre-processed indicia information, determined during the processing of the indicia using the first program code, to a second program code;
- and
- decoding the indicia using at least the pre-processed indicia information by the second program code.
