摘要： An input image signal 101 is divided into MC block units and, when coding processing is performed in these divided units, a motion compensation section 107 generates a motion-compensated prediction image 106a by detecting movement amounts in predetermined MC block units, a smoothing filter section 124 performs, with respect to the prediction image 106a, smoothing of pixels located at the boundaries of adjoining MC blocks on the basis of predetermined evaluation criteria, and a prediction residual signal 108, which is obtained from the difference between the prediction image 106b obtained by the smoothing, and the input image (input image signal 101), is encoded. Accordingly, it is possible to use relatively straightforward computation to perform processing, with respect to a prediction frame image generated by block-unit motion-compensated interframe prediction (MC), to adaptively smooth a discontinuous waveform generated between MC blocks of the prediction frame image, whereby the efficiency of low bit rate coding that employs interframe MC is improved.

摘要： As an embodiment of a moving picture encoding apparatus, a moving picture type judgment section judges whether an input moving picture is a stereoscopic picture and, when the moving picture is a stereoscopic picture, a stereoscopic picture identifier is set to “1” and a moving picture rotation section rotates the moving picture clockwise by +90 degrees or −90 degrees. On the other hand, when the moving picture is not a stereoscopic picture, the stereoscopic picture identifier is set to “0” and the moving picture is not rotated. Then, a moving picture interlaced encoding section produces an encoded bit stream by performing interlaced encoding of the moving picture and a stereoscopic picture identifier encoding section produces encoded information by encoding the stereoscopic picture identifier. Further, a multiplexing section produces a multiplexed encoded bit stream by multiplexing the above-mentioned encoded bit stream and encoded information.

摘要： A prediction mode is selected in accordance with a type of a moving picture. When an interframe prediction mode is selected as the prediction mode, a motion vector for the moving picture is detected. Motion compensation for the moving picture is performed based on the type of the moving picture, the prediction mode, and the motion vector. A spatial prediction section performs a spatial prediction for the moving picture based on the type of the moving picture and the prediction mode. An orthogonal transformation for a predictive residue signal obtained as a difference between the picture signal obtained by the motion compensation or the spatial prediction and the input picture signal is performed, based on the type of the moving picture and the prediction mode. Variable length encoding for the picture data after the orthogonal transformation is performed, based on the type of the moving picture and the prediction mode.
