摘要:
A plurality of bar-code candidate areas are calculated from scan data that is acquired by scanning a bar code. Feature data, which represents a specific feature, is calculated for each of the bar-code candidate areas. The bar-code candidate areas are evaluated based on their feature data to thereby determine a bar-code candidate area that has the highest probability of being a bar code. The specific feature includes any one or more of length of a differential waveform, average energy, and number of peaks in the differential waveform.
