Two-dimensional code recognition processing method, two-dimensional code recognition processing apparatus, and storage medium |
摘要 |
A two-dimensional code recognition processing method for recognizing a two-dimensional code lade of a plurality of square cells arranged in accordance with predetermined layout rules. The method comprises the steps of: generating binary data from image information acquired externally in accordance with a predetermined threshold value; detecting a reference cell serving as a reference in recognizing the two-dimensional code based on the binary data generated in the binary data generating step; detecting corner cells each located in a predetermined search range with respect to the reference cell detected in the reference cell detecting step, on the basis of the binary data generated in the binary data generating step; and detecting code data assigned to the two-dimensional code existing inside an area of a code part enclosed by the reference cell and by the corner cells on the basis of the binary data generated in the binary data generating step.
