摘要 |
A device and method to read bar-codes in which a ratio of a number of modules is compared to a reference module width character included in a bar-code. The number of modules is rounded up and off based upon the number of modules that includes the error component. When the error amount in the ratio exceeds a permissible value, the character in question is demodulated based on the resulting rounding up or off.
