A two-dimensional code having a rectangular region is provided. In the rectangular region, there are code blocks composed of a plurality of cells, a first specific pattern specifying the positions of the cells, and a second specific pattern separating the code blocks from a background of the code. The first specific pattern is located at a specified corner of the rectangular region. The second specific pattern is located along one or more of first borders along which the first specific pattern is located, the first borders being part of the borders of the rectangular region. The code blocks include error-correction code blocks, which are located along second borders which are different from a border of the borders along which the second specific pattern is located. The second borders are part of the borders. Compressed data code blocks are also arranged in the same way as the error-correction code blocks. |
