MOTION PICTURE ENCODING DEVICE AND MOTION PICTURE DECODING DEVICE

摘要

PURPOSE: A motion picture encoding device and a motion picture decoding device are provided to improve coding efficiency by improving the predicative efficiency of a chrominance component. CONSTITUTION: The first to third chrominance motion vector generation units generate a chrominance motion vector using a luminance motion vector. A selection unit(230) selects one of the first to third chrominance motion vector generation units to be used to receive a reference field parity and an encoding field parity of a motion vector and generate a chrominance vector. A chrominance motion vector generation unit selected by the selection unit(230) generates a predictive chrominance vector from motion vector information of luminance information.
