Image processing apparatus and method, program recording medium, and program

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. A class code is determined based on the extracted pixel data. Based on coefficient seed data of the class and spatial parameters, image quality parameters, and a frame phase of the pixel of interest, a coefficient generator generates coefficient data of the class for use in calculation of pixel data of each pixel of interest. A processing circuit calculates pixel data of the pixel of interest in accordance with a prediction equation using tap data corresponding to the pixel of interest, and the coefficient data corresponding to the class code read from a memory.
