Abstract

An image processing apparatus for joining a shadow to, masking, or otherwise processing a color image. When an original color image is processed to have a shadow or to be masked, for example, the processed image is adequately colored. A shadow whose color components are consistent with those of an original color image is formed in a predetermined direction. An image produced by masking is also consistent in color with an original color image. Such mask processing and shadow processing may even be executed in combination without any contradiction in color.
