ABSTRACT:
Method and apparatus for the conversion or generation of a video signal intended to be displayed on an image display with different luminance response times for rise and fall. The conversion or generation of the video signal is so that motion artefacts which are caused by the difference in luminance response times for rise and fall such as large area luminance jumps, large-area flicker and faulty temporary large-area luminance are fundamentally cancelled in the displayed image.
