Abstract:
1. A method for reading barcode information comprising: a first step of reading barcode information recorded on a medium by using a reading means, and converting the read information into binarized information with a predetermined binarization threshold; a second step of measuring each element width of a plurality of black elements and white elements constituting the barcode information in due order on the basis of the binarized information, and creating an element width matrix through placing the element width values in order of the measurement; a third step of judging each element width to be either thin or thick according to a prescribed rule, and converting the element width matrix into a bit pattern according to the judgment result; a fourth step of determining a character corresponding to the bit pattern; a fifth step of re-judging each element width to be either thin or thick according to the number of thick elements constituting a character, in a case where there exists no character corresponding to the bit pattern in the fourth step, and re-converting the element width matrix into a bit pattern according to a result of the re-judgment; and sixth step of determining a character corresponding to the bit pattern as a result of the re-conversion.
