摘要

PROBLEM TO BE SOLVED: To generate an analyzable color two-dimensional barcode from a plurality of two-dimensional barcodes in the case of employing an image processing method for overcoating a color of an upper cell on a color of a lower cell.;SOLUTION: A color two-dimensional barcode generating method includes the steps of: providing a first two-dimensional barcode and a second two-dimensional barcode having colored cells in different colors; changing the shape of the cell of the first two-dimensional barcode in such a way that a part of the cell of the second two-dimensional barcode (see Figure 8(B)) can be seen when the cells are overlapped as shown in Figure 8(A); and generating a color two-dimensional barcode by overlapping the first two-dimensional barcode on the second two-dimensional barcode, and outputting the generated barcode.;COPYRIGHT: (C)2013,JPO&INPIT
