Abstract
If additional data is embedded in electronic image data with a low embedding strength such that images based on the image data are displayed without degradation of image quality, the additional data could not be extracted from printed images. An image processing apparatus that processes electronic image data to which additional data representing additional information such as copyright ID information is appended is provided with an additional data recognition unit for recognizing that first additional data representing additional information is appended to image data from which to form images, and an additional data embedding unit, when it is recognized by the additional data recognition unit that the first additional data is appended, for embedding second additional data representing additional information in the image data, wherein the additional information is extractable from formed images.
