Decoder learning function

This function is to automatically change parameters for criteria and threshold level used to judge

on decoding bar code data so that scanning a bar code printed in poor quality can be improved.

However, after changing the relevant parameters for the decoder learning function, the individual

scanning characteristics of each terminal may be degraded. To avoid such degrade, the integrated

decoding system starts decoding with the standard decoder and then changes with the customized

decoder if decoding at the first stage fails. If the decoding at the end of the process does not

succeed, the decoder learning function is used to ensure it to be succeeded. Setting either “Enable”

or “Disable” for the function to be effect can be set. See the decoding process flow in Fig. 3.3.
