Two-Dimensional Code Generation Method, Two-Dimensional Code, Two-Dimensional Code Recognition Method, and Image Recognition Device

摘要

A two-dimensional code in which given data is encoded as a two-dimensional image. The two-dimensional code includes as image elements: points each of which is placed at point placement reserved position in a two-dimensional region based on a binary data string uniquely associated with the given data according to a preset binary data string placement condition; and a line connecting each of the points and a connection target point according to a preset connection condition. The two-dimensional code is formed as a two-dimensional image by causing the line connecting the points to have a given width.
