<p><P>PROBLEM TO BE SOLVED: To more efficiently obtain a configuration capable of setting a reference area which becomes a standard of each color to be displayed on a cell, and capable of accurately separating a code area from a back ground in a two-dimensional code to be represented with colors. <P>SOLUTION: In the two-dimensional code 1, a plurality of cells "C" are two-dimensionally disposed within a rectangular area, and information encoded by color, density, or intensity of each cell is configured as a color code for color representation. The two-dimensional code 1 is provided with color reference patterns 21 to 27 which become to be standards of cell display colors to be used for each cell within the rectangular area. In the color reference patterns 21 to 27, the plurality of cells "C" are disposed with a matrix state, and at least a part of a cell string is configured as a boundary portion of the rectangular area. Moreover, the cell string configured as the boundary portion of the rectangular area in the color reference patterns 21 to 27 are configured by a predetermined color matrix for separating the rectangular area from the back ground of the rectangular area. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
