Abstract
Described is a system and method for bar code decoding. The system comprises first and second digitizers and a processor. The first digitizer outputs a first digitized representation of a bar code. The second digitizer outputs a second digitized representation of the bar code. The processor compares the first and second digitized representations to yield a set of parameters. The processor selects one of the first and second digitized representations to be decoded as a function of the set of parameters.

A method, comprising:
- generating first and second digitized representations of a bar code;
- comparing the representations to yield a set of parameters before decoding the first or second digitized representations;
- selecting one of the representations for decoding as a function of the set of parameters;
- and
- wherein the set of parameters includes at least one of (i) a first number of one or more sequences of elements in the second digitized representation corresponding to a single element in the first digitized representation, (ii) a first width of a narrow element in the one or more sequences, (iii) a second width of a narrow element between margins of the bar code in the first digitized representation and (iv) a third width of a narrow element between margins of the bar code in the second digitized representation.
A computer-readable storage medium storing a set of instructions, the set of instructions capable of being executed by a processor, the set of instructions performing the steps of:
- generating first and second digitized representations of a bar code;
- comparing the representations to yield a set of parameters before decoding the first or second digitized representations;
- selecting one of the representations for decoding as a function of the set;
- and
- wherein the set of parameters includes at least one of (i) a first number of one or more sequences of elements in the second digitized representation corresponding to a single element in the first digitized representation, (ii) a first width of a narrow element in the one or more sequences, (iii) a second width of a narrow element between margins of the bar code in the first digitized representation and (iv) a third width of a narrow element between margins of the bar code in the second digitized representation.
