Compression/decompression system for image data. |
摘要 |
<p>A compression/decompression system for an image data performs a motion compensated prediction and an orthogonal transformation in a time-direction with respect to a plurality of picture planes by combining one pair of an A-frame and a B-frame. The system has a motion estimation element (24) for obtaining a motion vector signal (24a) with respect to the A-frame from a first block signal, a motion prediction element (25) for outputting a third block signal obtained by performing a motion compensated predic- tion with respect to the A-frame on the basis of the motion vector signal, and an orthogonal transformation element (TT) for outputting a first and second transformed informa- tion obtained by performing an orthogonal transformation in the time-direction with respect to a plurality of picture planes on the basis of the first and third block signals. <IMAGE></p> |
