Abstract
Certainty of detecting watermarks embedded in a color image is increased. Image date acquisition means of an image processing device acquires image data on a color image having a plurality of color channels. Numerical value acquisition means acquires respective numerical values in the plurality of color channels contained in a pixel value of the color image based on the image data acquired by the image data acquisition means. Image processing means embed a watermark in each of the plurality of color channels by changing the numerical value acquired by the numerical value acquisition means.
