Abstract
The aim is to reduce the influence of the filming environment of an image that represents a two-dimensional code when determining a color that has been added to a cell in the two-dimensional code. Disclosed is a two-dimensional code (100) in which a mark is added to each cell group in an information color or a combination color that is correlated with the information indicated by the cell group, and the mark for each cell (C) in the cell group is added in a specified coordinate color within a component domain from among a component model representing the distribution of color components, that is disposed in a positional relationship void of mutual interference.
