<P>PROBLEM TO BE SOLVED: To accurately decode a two-dimensional code in a code reader. <P>SOLUTION: This code generation device is configured so that reading performance information RP showing the performance of reading two-dimensional codes TDC1 to TDC3 is acquired by an acquisition part 26, and an encoding part 28 encodes registration screen acquisition addresses GF1 to GF3 based on reading performance information RP, and generates the two-dimensional codes TDC1 to TCD3 with code resolution Cmm and code size CS corresponding to the code reading performance of the code reader 14, thereby a data acquisition device 11 displays the two-dimensional codes TDC1 to TDC3 with the code resolution Cmm and the code size CS corresponding to the code reading performance of the code reader 14, and the code reading device 14 easily reads the two-dimensional codes TDC1 to TDC3, and thus the code reader 14 accurately decodes the two-dimensional codes TDC1 to TDC3. <P>COPYRIGHT: (C)2008,JPO&INPIT |
