TWO-DIMENSIONAL CODE, ENCODING DEVICE, ENCODING PROGRAM AND TWO-DIMENSIONAL CODE READER

摘要

PROBLEM TO BE SOLVED: To provide a preferred technique to inhibit degradation of a recognition rate of colors added to each cell of a two-dimensional code composed of array of multiple cells.

SOLUTION: Encoding information using colors whose recognition rate is relatively high among colors that can be added to a cell is generated through; acquisition of encoding object information including information about amount and a type of information to be encoded, structure of a two-dimensional code, types of colors that can be added to a cell and a recognition rate of each color (S13); setting of configuration of a cell group and the number of colors required for encoding based on the information (S15); decision of a color to be used based on a recognition rate of each color for combination of a color of a separator (110) and a color of a cell (S17); setting of a color of a cell group corresponding to each type of information using the decided color to be used (S19); and generation of encoding information based on the set information (S21). Then, an inputted information group is encoded using the generated encoding information.
