Abstract:
High-quality video is provided using a small amount of coded bits. The moving picture decoding method performs inter-frame prediction processing. With the aforementioned inter-frame prediction processing, blocks with similar motion vectors from among the motion vectors in multiple blocks that have already been decoded are combined and a combined area is computed. A predicted vector for a target block to be decoded is computed using the motion vector of the aforementioned combined area, and a motion vector for the aforementioned target block is computed based on the aforementioned predicted vector and a difference vector which is included in a coded stream that is input. A predicted image is generated using the aforementioned motion vector, and a difference image which is included in the aforementioned coded stream and the aforementioned predicted image are added to generate a decoded image.

Claim (Index 1):
A moving picture decoding method comprising:\n a first step to receive encoded information of a target block to be decoded by an inter prediction process, the encoded information being encoded without a frequency transform process; a second step to decode prediction difference data of the target block from the encoded information without the frequency transform process; a third step to determine by which prediction mode the target block is encoded; a fourth step to generate a prediction image by the prediction mode determined by the third step, wherein if the target block is encoded by an intra prediction mode, a prediction image is generated by the intra prediction mode, wherein if the target block is encoded by a motion vector combined area mode, the prediction image is generated by using a motion vector determined so as to be in common with a motion vector of an adjacent block adjacent to the target block without adding a difference vector, based on a status of motion vectors of a plurality of adjacent blocks adjacent to the target block; and wherein a status of a motion vector of a previous frame is considered in the determination of the motion vector to be used for the generation of the prediction image in the fourth step, and a fifth step to generate a decoded image of the target block based on the prediction image generated in the fourth step and the prediction difference data decoded in the second step.
