Abstract
An image input section selects a plurality of sample points from an input image, and passes the density values of the sample points and pixels around them to a feature parameter extractor. The feature parameter extractor calculates the feature parameters of each sample point and passes them to a density modification function generator. The density modification function generator creates a density modification function for each sample point and passes the density modification function data to a density modification function modifier. The density modification function modifier determines a density modification function for all of the pixels, including those other than the sample points, and passes this density modification function data to a processor. The processor modifies image data delivered from the image input section, and passes the modified image data to a modified image output section.
