ABSTRACT:
An image processing apparatus in which output pixels of an output image are generated from one or more input images using motion vectors having a sub-pixel accuracy. A motion vector allocator allocates motion vectors in the pixels, and compares a current output pixel with test image areas pointed to by motion vectors in the pixels to detect a most suitable motion vector for the current output pixel. A pixel generator operates in a first mode if the output pixel is within a threshold displacement from an image region having substantially different motion characteristics to those of that output pixel, and in a second mode otherwise. The pixel generator includes a spatial filter generating an output pixel value at a required pixel position to a sub-pixel accuracy.
