Abstract
A two-dimensional code having a rectangular region is provided. In the rectangular region, there are a plurality of code blocks, a first specific pattern, and error-correction code blocks. Each code block is composed of a plurality of cells aggregated together and formed to have both a specified corner in the rectangular region and the plurality of code blocks arranged in the rectangular region. The specific pattern is used to specify the positions of the cells. The error-correction code blocks are contained in the code blocks and formed to correct an error. The error-correction code blocks are arranged contiguously to part of the borders of the rectangular region. The part of the borders is displaced from the first specific pattern. Compressed data code blocks are also arranged in the same way as the error-correction code blocks.
