Two-dimensional code with a logo, device for generating a two-dimensional code with a logo, method for generating a two-dimensional code with a logo, and program

The disclosed device (1) for generating a two-dimensional code with a logo determines the color of a two-dimensional code, to be superimposed onto a logo image, by adjusting the L value (luminance) of said color. This makes it possible to generate a two-dimensional code with a logo wherein said code is readable regardless of post-processes after printing, ambient light, or the like. Also, in said two-dimensional code with a logo, cells superimposed on the image of a tiger character, the design of which is easily marred, are smaller than cells superimposed on a background area, thereby ensuring that the design of the logo image comes across without hampering the readability of the information.
