Motion compensation for plasma display panel

Dynamic false contour is a perceivable motion artifact in plasma display panel when displaying fast moving images. One of the method to remove the dynamic artifact is to compensate the subfield contend by motion estimation. But it requires accurate estimation of the motion vector for the video images. A novel motion vector extraction algorithm for MPEG video stream is evaluated. A comparison between extracted motion vectors and the vectors acquired by full search block match method is presented. The method to compensate the subfield contends by using the extracted motion vector is also discussed. The simulation results imply that using the extracted motion vector to compensate part of the subfield contents can improve the subjective image quality on plasma display panel.
