Abstract
The objective of the invention is to make high-efficiency compressed coding for images. In coding of video signals in this application example, the edge is extracted in a frame of the input image in block . In block , classification is made into blocks where edge is present and blocks free of edge. In block , for the block where edge is present, based on the correlation between the edge direction and the distribution of the DCT coefficients, the optimum scanning order is determined and coding is performed by the scanning order.
