Abstract
The invention relates to a method for processing data of video pictures for displaying the pictures on a display device like a Plasma Display Panel. The existing false contour effect compensation methods which make a false contour compensation based on shifting sub-field code word entries along the direction of the motion vector of a current pixel, produce an artifact in the pictures, in case of object crossings. In the appearing area there is a lack of light generation.The invention solves this problem by checking whether an area exists in the picture which is currently hidden but will appear in a next frame and providing an adapted compensation method for “hole filling”. The invention also gives a solution for an improved compensation method which is based on a dragging of sub-field code word entries along a motion vector direction to a current pixel.
