Abstract
In a two-dimensional code generation device (), a white point determiner () determines a white point in an environment to output a two-dimensional code. A threshold acquirer () acquires a threshold of lightness used by a reading device for reading multiple cells in binary, the threshold being represented in a device-independent color space that is based on the white point determined by the white point determiner (). A two-dimensional code generator () generates a two-dimensional code expressing information by a distribution pattern of multiple cell dots formed by coloring the multiple cells in a color of lightness equal to or higher than the threshold acquired by the threshold acquirer () and in a color of lightness lower than the threshold.
