More Information
Summary:A shifting amount of color compensation amount is calculated based on a shifting amount of color obtained from a shifting amount of color storage unit for each image forming unit, and shifting amount of color compensation in the pixel unit is performed by executing address conversion using the calculation result. A feature of an image to be processed is detected, and color density conversion compensation for performing shifting amount of color compensation in less than the pixel unit is performed according to the detected feature. Furthermore, half-tone processing or exceptional processing is selectively executed according to the detected feature.
