Abstract:
A bar code image processing apparatus comprising:scanning means for scanning all patterns involved in a document image which includes at least one bar code;labeling means for labeling all of the scanned patterns of said document image and for detecting a plurality of feature quantities of each labeled region, including a center position of each labeled region;region detecting means for making a group of labeled regions spaced at a predetermined positional relationship based on feature quantities of said labeled regions and for detecting a bar code candidate region; anddecoding means for identifying a type of each bar involved in said bar code candidate region and for decoding the bar code, wherein a combination of said center position of said each bar code and another feature quantity of said each bar code is considered in identifying the type of each bar,wherein by scanning all the patterns involved in the document image and by labeling all of the scanned patterns, said scanning means obtains scanned patterns without using expansion and contraction processing.
