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

摘要

A logo-added two-dimensional code creation device determines the color of a two-dimensional code to be superimposed on a logo image by adjusting the L value indicating the color lightness, whereby a logo-added two-dimensional code readable regardless of influence of post-printing processing and/or ambient light can be created. The logo-added two-dimensional code has smaller cells superimposed on the tiger character that can easily lose the design integrity than the cells superimposed on the background part, ensuring the design integrity of the logo image without impairing the readability of information.
