The second coding of imaging the coded information to a single-gradation map is performed. The third coding of combining the imaged information in unit of the basic components to make a square, triangle or circular puzzle or convert the basic components into a single pixel is executed. A coding key code is inserted into the coded image. Video information image is coded and inputted to a processor. Gradient correction, size correction and coding key code of the inputted image are extracted. The security code is inputted or extracted from the coded image. The image is decoded and restored.
