<p>An image processing apparatus and method, a program storage medium, and a program are provided to process a region including components of a natural image and a region including components of an artificial image respectively to improve the picture quality of each region. An image processing apparatus includes a broad-range feature quantity extractor(911), a broad-range artificiality calculator(912), a narrow-range feature quantity extractor(914), a narrow-range artificiality calculator(915), and an artificiality calculator(913). The broad-range feature quantity extractor extracts a broad-range feature quantity for a noted pixel of a first image. The broad-range artificiality calculator calculates degrees of artificiality according to position relation of the extracted broad-range feature quantity with respect to a statistical distribution range of an artificial image of the first image. The narrow-range feature quantity extractor extracts a narrow-range feature quantity from pixels located in a predetermined region for the noted pixel of the first image. The narrow-range artificiality calculator calculates degrees of artificiality according to position relation of the extracted narrow-range feature quantity with respect to the statistical distribution range of the artificial image. The artificiality calculator combines the broad-range degrees of artificiality and the narrow-range degrees of artificiality to generate degree of artificiality of the noted pixel.</p> |
