Since a separate affine transformation unit executing a series of transformation processing operations such as rotation, vertical or lateral movement, enlargement or contraction, or {HEAD ~ change} of perspective or {TAIL ~ orientation} may be included within the encoding device, the processing system may be simplified while transformation can be quickly carried out
