Abstract
An image processing apparatus has an image analyzer including a feature detector, a feature combiner, and a resolution discrimination signal generator. For each pixel in a prescribed area of an input image, the feature detector outputs a representative difference value obtained from the pixel values of pixels positioned, with reference to that pixel, at prescribed intervals. The feature combiner outputs a combined feature value obtained from the representative difference values obtained for each pixel in the described area. The resolution discrimination signal generator outputs a resolution discrimination signal obtained from the combined feature value. The resolution discrimination signal has a monotonic non-decreasing relationship to the combined feature value. The resolution discrimination signal indicates an extent to which the input image includes signal components with frequencies equal to or greater than a particular frequency determined by the prescribed intervals.
