发明名称 TWO-DIMENSIONAL CODE, IMAGE READER, IMAGE READING METHOD, PROGRAM, AND STORAGE MEDIUM
摘要 PROBLEM TO BE SOLVED: To easily read information when a two-dimensional code is distorted.SOLUTION: The two-dimensional code including a plurality of cells constituted of white and black is provided with a control point or line for, when the two-dimensional code image is photographed to generate a two-dimensional code image with a distorted shape, specifying a position of reading information from the two-dimensional code image with distorted shape. When the two-dimensional code is photographed in the distorted state, the distortion is corrected by using a shape deformation method represented by an FDD method and a DDM method with the control point or the like in the two-dimensional code image used as an original point so as to read the information from the two-dimensional code image.
