PROBLEM TO BE SOLVED: To prevent an image representing a two-dimensional code from being influenced by an imaging environment, in specifying a color assigned to a cell in the two-dimensional code.

SOLUTION: In the two-dimensional code 100, each cell group is marked with an information color or combination color associated with information to be represented by the cell group, and each cell C in the cell group is marked with the color of a specific coordinate in a component area arranged in a positional relation without mutual interference in a component model showing a distribution of color components.
