<p><P>PROBLEM TO BE SOLVED: To achieve multi-coloring and reduction of a cell for recording electronic data with a two-dimensional color code with high density. <P>SOLUTION: A two-dimensional color code is configured of a guide code part, having a code system for easily reading and decoding data and a data recording code part having a code system for recording data with high density, and numerical information, such as, the number of cells necessary for the determination of the position and decoding of the data recording code part, and the shortening of the processing time is obtained by the reading and decoding of the guide code part by an image-receiving device, so that it is possible to determine the position of a measurement pixel to be used for the determination of the color of each cell of the data recording code part with high accuracy and in a short period of time. Also, when there is any decoding error, the error is corrected by shifting the position of the measurement pixel, and the determination to which use color the color of each cell belongs is performed, not by the contrast of the color with a reference color displayed in the periphery of a two-dimensional code but rather by the quantization of the color of the pixel in the cell into the use color so that it is possible to increase the recording density, while maintaining accuracy of the determination of the color of the cell. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
