PROBLEM TO BE SOLVED: To exactly distinguish areas of characters and photographs from an inputted image a short time. SOLUTION: This image processor is provided with a binarization part 102 to divide the inputted image into foreground and background, an integrated threshold setting part 103 to create histogram of a background run by every line (or column) from the results of the binarization part 102 and to set a first integrated threshold for each line (or column), an integration processing part 104 to perform integration processing to the foreground by each line (or column), based on the first integrated threshold, a labeling part 105 to attach the same label to continuous pixels to the foreground integrated by the integration processing part 104 and to simultaneously constitute rectangles and an attribute detecting part 106 to distinguish the characters (strings), graphics or the photographs, tables, etc., by using at least one featured value of the rectangles labeled by the labeling part 105.
