According to an image processing method for performing color processing in accordance with a plurality of image objects, image data representing the plurality of image objects is input. The relationship between the plurality of image objects is analyzed. The plurality of image objects are grouped based on the result of analysis. The same color processing condition is set for the plurality of image objects belonging to the same group. Thus, the same color processing condition is set for the plurality of image objects divided from a single original image, thereby obtaining a high-quality output image.
