ABSTRACT:
In an image signal converting method and an image signal converting apparatus, it is possible to perform a proper classification considering various signal characteristics of input image data and convert low-resolution input image data to high-resolution image data by using not only a classifying means 56 for classifying input images in accordance with the level distribution pattern of the input images but also a classifying means 50 for classifying input images in accordance with the movement of the input images and deciding the final class D32 of input image signals by both CLASS0 and CLASS1 obtained by both classifying means 50 and 56.
