Abstract
Abstract An image processing apparatus previously stores information on particular kinds of image, determines the degree of similarity between an input full-color image signal and the information on particular kinds of image, controls conditions for addition of a particular pattern previously stored according to a result of the determination, and outputs an image by adding or not adding the particular pattern to the full-color image signal according to the addition conditions.
