ABSTRACT:
A preprocessing device used in a video coding apparatus, comprising a motion compensation prediction estimating unit for detecting a change of an video from a current picture and a past picture to generate change data, and a filter for deforming the current picture in accordance with the change data generated by the motion compensation prediction estimating circuit such that a deformed current picture is sent to a motion compensation prediction coding section of the video coding apparatus to be coded.
