摘要

PPROBLEM TO BE SOLVED: To embed an image that a person can recognize in an original image in an easy manner. PSOLUTION: Two kinds of output profiles (color separation conditions) of the same color reproduction and different ink combinations are used and while a first output profile is allocated to one area of the original image Ia, a second output profile is allocated to the other area of the original image Ia. Namely, the output profiles are changed according to pixel positions in the image to perform image processing, thereby embedding the buried image Ii in the original image Ia.
