摘要： According to an embodiment, a video compression apparatus includes a first compressor, a second compressor, a partitioner and a communicator. The first compressor compresses a first video to generate a first bitstream. The second compressor sets regions in a second video and compresses the regions so as to enable each region to be independently decoded, to generate a second bitstream. The partitioner partitions the second bitstream according to the set regions to obtain a partitioned second bitstream. The communicator receives region information indicating a specific region that corresponds to one or more regions and selects and transmits a bitstream corresponding to the specific region from the partitioned second bitstream.

摘要： According to an embodiment, a multi-view image encoding device encodes a multi-view image including a plurality of viewpoint images. The device includes an assignor, a predictor, a subtractor, and an encoder. The assignor assigns reference image numbers to the reference images according to a number of reference images used in predicting already-encoded blocks obtained by dividing the viewpoint images. The predictor generates a prediction image with respect to an encoding target block obtained by dividing the viewpoint images by referring to the reference images. The subtractor calculates a residual error between an encoding target image and the prediction image. The encoder encodes: a coefficient of transformation which is obtained by performing orthogonal transformation and quantization with respect to the residual error; and the reference image numbers of the reference images used in generating the prediction image.
