Abstract:
1. An image signal processing apparatus for processing a first image signal including multiple items of pixel data, said first image signal being generated by decoding a motion-compensated predictive encoded-digital image signal, to allow the first image signal to be converted to a second image signal including multiple items of pixel data, said apparatus comprising: class detection means for detecting a class to which pixel data of a target position in said second image signal belongs, based on at least motion compensation vector information having sub-pixel accuracy which has been used at the time of obtaining the pixel data of said first image signal corresponding to the target position in said second image signal; and pixel data generation means for generating pixel data of the target position in said second image signal in correspondence with said class detected in said class detection means, wherein the class detection means detects a class difference based on whether the motion compensation vector has a sub-pixel component.
