IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND RECORDING MEDIUM

摘要

An image processing apparatus for generating a pattern of a recording material to be overlapped on an original image for forming an image of a target region extracted from the original image, includes an arithmetic unit calculating a feature amount of an image data included in a boundary region of the target region; a determination unit determining a degree of change of color in the boundary region based on the feature amount; and a pattern generation unit determining a gradation of the pattern of the recording material for the boundary region in accordance with the degree of change of color in the boundary region.
