Claim One:
1. A method for the optical detection of a linear barcode pattern and for determining a symbol sequence which is coded by the linear barcode pattern, wherein the method proceeds from a blurred raw picture and comprises the following steps: taking a raw picture of the linear barcode pattern; pre-processing the raw picture of the linear barcode pattern for producing a single output linear barcode pattern or a sequence of output linear barcode patterns, wherein each output linear barcode pattern corresponds to a brightness course along the linear barcode pattern and division of the complete output linear barcode pattern into sequence of output linear barcode patterns; comparing the output linear barcode patterns or the single output linear barcode pattern with stored reference linear barcode patterns of linear barcode patterns, wherein the reference linear barcode patterns in each case correspond to a brightness course and division of the complete output linear barcode pattern into sequence of output linear barcode patterns of blurred images of non-blurred nominal linear barcode patterns, and at least one symbol is assigned to each reference linear barcode pattern; determining, for the single output linear barcode pattern or for each of the sequence of output linear barcode patterns, in each case the reference linear barcode pattern which has the greatest similarity to the output linear barcode pattern; outputting, transmitting or storing the symbols which correspond to the determined linear barcode reference patterns, according to the single output linear barcode pattern or the sequence of output linear barcode patterns, as a symbol sequence.
