A DPCM picture coding with adaptive prediction is discussed. The method prevents from blurring edges or contours of reconstructed images. The information on the edges is derived from the reconstructed neighboring pixels. Therefore, no additional information is required to select a suitable prediction. The effectiveness of the method compared with fixed type DPCM is shown by the simulations.
