Abstract
Method of motion-compensated video processing such as standards conversion, uses motion vectors assigned on a pixel-by-pixel basis. The pixels of an input video signal are written to locations in a video store determined by the motion vector assigned to that pixel. Multiple vectors can address a single written pixel to enable mixing of backward and forward vectors. A confidence value governs the accumulation of pixels and the later interpolation between motion compensated fields.
