ABSTRACT:
An image processing apparatus corrects color-difference amounts of main image information by a plurality of color-difference amount correction processes and performs a plurality of color-difference modulation processes based on the processing results of the plurality of color-difference amount correction processes and a plurality of key information items. Further, it subjects the processing results of the plurality of color-difference modulation processes to the selecting/synthesizing process based on sub-information and superposing the processing result of the selecting/synthesizing process on the main image information to form synthesized image information having sub-information embedded in an invisible state in the main image information.
