Abstract
In an image processing apparatus, a reduced image in which an input image having a color pattern of a plurality of colors of different pixel densities is reduced is generated. A luminance signal is generated from the reduced image. A contour compensation signal is generated from weighted color signals of the reduced image. The luminance signal and the contour compensation signal are combined. If a reduction ratio of the reduced image is greater than a threshold, a weighting used for a color signal for which a pixel density is high in the input image is increased in comparison to a case where the reduction ratio is not greater to the threshold.
