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.

Apparatuses and methods generating a two-dimensional code with a logo

The display unit displays a QR Code (registered trademark) (), a Data Matrix (Data Code) (), and an Aztec Code (), all presenting the same information such as flight reservation details, for example, for 1.0 second each by turns. Consequently, there is no need of installing a two-dimensional code reader for QR Code (registered trademark), a two-dimensional code reader for Data Matrix (Data Code), and a two-dimensional code reader for Aztec Code and only any one of the two-dimensional code readers is necessary to read information such as flight reservation details.
