Abstract
An image processing apparatus records an input image signal into another recording medium or displays the input image signal on a display device. When a digital image signal having superimposed thereupon an electronic watermark is input, an identification circuit identifies the method employed to superimpose the electronic watermark. A decode circuit decodes the electronic watermark by employing the electronic watermark superimposing method identified by the identification circuit.
