IMAGE PROCESSING UNIT FOR AND METHOD OF PROCESSING PIXELS AND IMAGE DISPLAY APPARATUS COMPRISING SUCH AN IMAGE PROCESSING UNIT

摘要

The image processing unit (603) for processing pixels of an image to be displayed on a display panel (702) in a plurality of sub-fields is designed to perform motion compensation. The motion compensation is executed in two parts which can be divided in a number of steps. In a pre-compensation part (816) optimal sub-field combinations are determined for the pixels of the image, i.e. which sub-field pixels should be on and which should be off. Motion vectors are used for this. The pre-compensation part is essential to compensate for errors which are inherent with the second part (818): shifting sub-field pixels with a discrete number of pixel positions (322) although the actual translation (308) is unequal to the extent of that discrete number of pixel positions (322).
