PROBLEM TO BE SOLVED: To easily correct distortion of a read image read by photographing a printing medium.SOLUTION: An information processor 1 deforms the entire shape of a two-dimensional code (code pattern) 5 in accordance with a photographing state of an image reader 2 for photographing a printing medium 4 to read an image, and performs control for printing the deformed two-dimensional code 5 together with print data on the printing medium 4. The image reader 2 acquires a correction parameter for correcting distortion of the read image by extracting and decoding the two-dimensional code 5, the entire shape of which is deformed in accordance with the photographing state from the read image photographed by an imaging part 26, and corrects the distortion of the read image on the basis of the correction parameter. |
