A system and method in which a sequence of motion images including a scene of interest is zoomed up and displayed smoothly at a specified arbitrary playback speed. Pixel data of taps corresponding to each pixel of interest in each unit of pixel block of an output image signal to be generated is extracted from an input image signal.

An image processing apparatus includes the following elements. A broad-range feature extraction unit extracts broad-range features from pixels located in a predetermined area in relation to a subject pixel of a first image. A broad-range degree-of-artificiality calculator calculates, in a multidimensional space represented by the broad-range features, the broad-range degree of artificiality from the positional relationship of the broad-range features to a statistical distribution range of an artificial image of the first image. A narrow-range feature extraction unit extracts narrow-range features from pixels located in the predetermined area in relation to the subject pixel of the first image. A narrow-range degree-of-artificiality calculator calculates, in a multidimensional space represented by the narrow-range features, the narrow-range degree of artificiality from the positional relationship of the narrow-range features to a statistical distribution range of the artificial image. A degree-of-artificiality calculator calculates the degree of artificiality of the subject pixel.
