Abstract:
Method for processing video pictures for display on a display device (39) having a plurality of luminous elements corresponding to the pixels of a picture, wherein the time duration for a video frame or video field is divided into a plurality of sub-fields (SF) during which the luminous elements can be activated for a light emission in small pulses corresponding to a sub-field code word which is used for brightness control, wherein for corresponding pixels of two or more pixel lines sub-field code words are determined which have identical entries for a number of sub-fields called common sub-fields (CSF), characterized in that, in cases where with the common (CSF) and remaining normal sub-fields (SF) no exact luminance representation of a given pixel value can be achieved, the unavoidable coding error is systematically shifted to the pixel or pixels with the highest pixel value.
