Video encoder, video decoder, and video motion estimation apparatus.

摘要

A video coding apparatus insuring a high coding efficiency even at a low bit rate is provided. The apparatus comprises a moving object analyzer 2 which extracts a moving part from an input picture signal, analyzes its motion and outputs a residual signal relative to a reconstruction image and motion parameters, a residue coding means 4 for coding the residual signal, a reconstruction means 3 for reconstructing a picture using the motion parameters and residual coded information and a variable length coding means 5 which performs a variable length coding of the motion parameters and residual coded information.
