Abstract: <P>PROBLEM TO BE SOLVED: To provide a simple method for embedding electronic watermark which does not select the kinds of the contents and whose watermark information can not be easily recognized, a method for detecting the electronic watermark capable of easily detecting the watermark information from the contents to which the watermark information is embedded, and a device for detecting the electronic watermark.  <P>SOLUTION: Pixel data of a second pixel w(k) constituting the watermark information w are embedded to the hue component of a first pixel P(k) constituting the contents P. The processing is applied to all the pixels constituting the contents P. And, the contents Pw are generated to which the watermark information w is embedded. Also, in addition to the contents Pw generated by the method, at least two or more base colors are provided. Photographing is executed by an image pickup device 200 in that state. The photographed base color and the base color before the photographing are compared with each other. As a result, color correction of the photographed contents is executed.
