<p>Hitherto, in order to encode digital image signals, a rather large amount of data is applied to an edge part. There is inevitably a limit to the reduction of data, and the efficiency of encoding the image signals is low. In the encoding apparatus, the image signals provided in units of frames, each having a plurality of pixel data items, are divided into macro groups, and the pixel data items in each macro group are combined, forming a group. The pixel data items of the group are encoded on the basis of the level data representing the signal level of the representative pixel data item in the group, the position data concerning all pixel data items of the group and the data representing the number of the pixel data items existing in the group. <IMAGE></p> |
