Abstract

A two-dimensional code recognition processing apparatus, and two-dimensional code recognition processing program storage medium for recognizing a two-dimensional code made of a plurality of square cells arranged in accordance with predetermined layout rules, wherein two-dimensional code recognition processing method comprises the steps of recognizing code data assigned to the two-dimensional code, from externally captured image information, and if a plurality of code data are recognized successively over time in the recognizing step, or if a plurality of code data are recognized from the same image information in the recognizing step, then linking the plurality of code data to generate expanded code data.
