Abstract
Color data, originally corresponding to different colors, are converted to the same density when gray-scale conversion is performed, and no boundary is distinguished. When performing the gray-scale conversion, color data of an object adjacent to an object to be processed is referred to. As a result of such reference, even if it is detected that the object to be processed and the object adjacent to the object to be processed have different colors, but are converted to the same density by the gray-scale conversion, the gray-scale conversion is performed in such a manner that the boundary between the objects can be identified.
