摘要： 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.

摘要翻译： 提供具有矩形区域的二维码。 在矩形区域中，存在多个码块，第一特定图案和纠错码块。 每个代码块由聚合在一起的多个单元组成，并且形成为具有矩形区域中的特定角部和布置在矩形区域中的多个代码块。 特定模式用于指定单元格的位置。 纠错码块包含在码块中并形成用于纠正错误。 错误校正码块与矩形区域的部分边界连续排列。 边界的一部分从第一种特定模式中移除。 压缩数据码块也以与纠错码块相同的方式排列。

摘要： 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.

摘要： An information code is provided as a light transmissive object in which an information code is formed. When visible light is radiated to the object, the object maintains its light transmissive state, with no presentation from an information code in the object. Light of a first wavelength band, which differs from the visible light, is radiated to the object, the information code produces an image on light of a second wavelength band which differs from the first wavelength band. From an information code reader, the light of the first wavelength band is radiated to the information code medium, during which the light of the second wavelength band from the code is received by the reader. Based on reception results of the light of the second wavelength band, the information code is decoded. By way of example, decoded results are used to determine if the information code is authentic.
