Claim:
1. A method of generating a logo-added two-dimensional code, the method comprising: determining a lightness of a logo image in which a logo is depicted on a background; comparing the lightness of the logo with a first lightness; generating the logo-added two-dimensional code on which a two-dimensional code representing given information by a distribution pattern of cells arranged in a matrix is superimposed by the logo image by: superimposing a part of the logo image on a first kind of cell when it is determined, based on the comparison of the lightness of the logo image to the first lightness, that the lightness of the logo image is lower than the first lightness, or superimposing a part of the logo image on both a first kind of cell and a second kind of cell when it is determined, based on the comparison of the lightness of the logo image to the first lightness, that the lightness of the logo image is equal to or greater than the first lightness; wherein the cells are different in size depending on which part of the logo image they are superimposed on; and wherein the second kind of cell has lower lightness than the first kind of cells.
