<p><P>PROBLEM TO BE SOLVED: To divert a part of an existing algorithm to reduce costs when a color two-dimensional bar code is used instead of an existing monochrome two-dimensional bar code. <P>SOLUTION: This two-dimensional bar code reading system is provided with: a loading means 13 for loading a two-dimensional bar code 1 in which each of a plurality of cells divided like a matrix is expressed in any of predetermined 2<SP>k</SP>colors as loaded data when the two-dimensional bar code 1 is read; a restoration means 52 for restoring original information from the loaded data; and a storage means 4 in which various kinds of information are stored. The system is also provided with a multilayering means 6 for converting the two-dimensional bar code into multilayered two-dimensional bar code 3 having k layers of two-dimensional bar code 2 in which each of the plurality of cells divided like the matrix is expressed in any of two colors, based on the loaded data, and performs processing for restoring the original information to the plurality of two-dimensional bar code 2 constituting the multilayered two-dimensional bar code 3. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
