ABSTRACT:
A video coding apparatus ensuring a high coding efficiency even at a low bit rate includes a moving object analyzer 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. The apparatus further includes a residual coding device for coding the residual signal, a reconstruction device for reconstructing a picture using the motion parameters, and a device that performs a variable length coding of the motion parameters and residual coded information.
