摘要： PROBLEM TO BE SOLVED: To provide a matrix type two-dimensional code including a hidden code, and a formation method and identification method of the hidden code.SOLUTION: This matrix type two-dimensional code presents a square shape, is recognized by a computer and is formed by arraying unit message color blocks without a clearance by a fixed rule. The hidden code is installed in the unit message color blocks and has a chromaticity different from that of the unit message color blocks. For the formation method of the hidden code, a small amount of high contrast hidden code is installed in the unit message color blocks and copy protection and a hidden function are realized. In association with this, this invention provides an identification method of the hidden code, and achieves the purpose of identifying the hidden code of the matrix type two-dimensional code by the changeover of high and low resolutions that a camera has and setting of an appropriate threshold.

摘要： PROBLEM TO BE SOLVED: To provide a matrix type two-dimensional code and a manufacturing method of the same.SOLUTION: This matrix type two-dimensional code has a regular square shape and formed by arranging unit message blocks without space by a fixed rule. The colors of the unit message blocks are black or white. The white unit message block of the matrix type two-dimensional code is expressed by a bright plane formed by die casting on a metal surface, and the bright plane of each white unit message block forms a tilt angle matching a horizontal plane. The black unit message block of the matrix type two-dimensional code is formed on a metal surface and expressed as a scattering surface located on the same plane parallel to the horizontal plane. The matrix type two-dimensional code has high stability and legibility and it is easy to determine. This invention also provides a manufacturing method of the matrix type two-dimensional code.
摘要翻译：要解决的问题：提供矩阵型二维码及其制造方法。解决方案：该矩阵型二维码具有规则的正方形形状，并且通过固定规则排列没有空格的单元消息块而形成。单位信息块的颜色为黑色或白色。矩阵型二维码的白色单元消息块由在金属表面上压铸形成的亮平面表示，并且每个白色单元消息块的亮平面形成与水平面匹配的倾斜角。矩阵型二维码的黑色单位消息块形成在金属表面上，并表示为位于与水平面平行的同一平面上的散射面。矩阵型二维码具有很高的稳定性和易读性，易于确定。本发明还提供了矩阵型二维码的制造方法。版权所有（C）2012，JPO＆INPIT
