PROBLEM TO BE SOLVED: To efficiently find positional information on an image of an electronic document from the positional information on a medium, when an image obtained by enlarging or reducing the image of the electronic document is printed on the medium. SOLUTION: The image processor is equipped with an image read section 21 which reads images, a dot array generating section 22 which generates a dot array from image, a block detecting section 23 which detects a block in the dot array and generates a code array, a synchronous code detecting section 24 which detects synchronous code in the code array, an identification code detecting section 30 which detects identification code from the code array, and an X coordinate code detecting section 40 which detects X coordinate code and the first half portion of the bit stream indicative of enlargement/reduction rate from the code array, and a Y coordinate code detecting section 45 which detects Y coordinate code and the second half portion of the bit stream indicative of the enlargement/reduction rate from the code array. Then, an information output section 50 converts the coordinate information, obtained by decoding the coordinate code, based on the enlargement/reduction rate obtained by decoding the bit stream, and outputs the converted coordinate information.
