Abstract:
A two-dimensional code recognition processing method for recognizing a two-dimensional code made of a plurality of square cells arranged in accordance with predetermined layout rules, the method comprising the steps of:recognizing code data assigned to said two-dimensional code, from externally captured image information; andlinking said plurality of code data to generate expanded code data, if a plurality of code data are recognized successively over time in said recognizing step, or if a plurality of code data are recognized from the same image information in said recognizing step,wherein said recognizing step comprises the step of recognizing said code data assigned to said two-dimensional code as well as layout information about said two-dimensional code from said externally captured image information; andsaid linking step comprises the step of determining priorities of said plurality of code data based on said layout information recognized in said recognizing step in order to link said plurality of code data in accordance with the priorities thus determined.
