摘要：
An image processing method, and corresponding apparatus, includes the steps of discriminating the color type of an input color image from an input color image signal, generating a pattern signal indicating a predetermined graphic pattern corresponding to the color type in response to the color discrimination, generating a density signal in accord with the input color image signal, and supplying a reproduction signal in accord with the pattern signal and the density signal to an image reproduction unit.
