Abstract
In an image processing apparatus, an extraction unit extracts a plurality of AC signals of a plurality of different frequency bands from image data input by an input unit; a generation unit generates first and second adjustment values for adjusting positive and negative components of an amplitude of each AC signal; an adjustment unit adjusts the amplitude of each AC signal using the first and second adjustment values; a detection unit detects a skin area from the image data; and a correction unit corrects image data of the skin area using the adjusted AC signals. The generation unit generates the first adjustment value such that the positive component of the amplitude of the AC signal of a first frequency band is less attenuated than that of the AC signal of a second frequency band which is lower than the first frequency band.
