PROBLEM TO BE SOLVED: To reduce labor when extracting information from an information embedded image about an information processing system. SOLUTION: When prescribed information is supperposed and embedded in an image to generate the information embedded image, additional information acting as a judgment criterion when information is extracted from the information embedded image is supperposed and embedded in a pixel at a predetermined position among images after information is generated by embedding the image in the information. When information from the information embedded image is extracted, the labor when extracting the information from the information embedded image can be reduced by reading additional information from the pixel at the predetermined position among the information embedded images, and extracting information from the information embedded image on the basis of the read additional information.
