ABSTRACT:
A highly efficient coding system includes a blocking device for dividing input signals representing sampled values into a plurality of blocks and outputting first output signals representing the plurality of blocks. An orthogonal transformation device effects an orthogonal transformation of the first output signals of the blocking device corresponding to the blocks, to divide the results of the orthogonal transformation into a mean component and variation components thereof, and to output the mean component and the variation components. A first normalizing device is provided for effecting interblock normalization of the mean component and the variation components outputted from the orthogonal transformation device and for outputting second output signals representing results of the interblock normalization, and a second normalizing device normalizes variation components of the second output signals of the first normalizing device in each of the blocks.
