In a high efficiency encoding system according to the invention, a picture is divided in many three-dimensional blocks, or blocks consisting of n areas belonging to each of n frames continuous in terms of time. The movement of the picture is decided in each block to develop movement information. The picture element number of each block is sub-sampled into (1/m), and the phases are sequentially shifted with respect to m blocks. Data of picture elements thinned by sub-sampling (i.e., not transmitted) are decoded, while picture data of a still portion is decoded excellently by the combination of sub-sampling patterns. |
