Abstract: Original design manufacturers increasingly source standard components from a variety of suppliers. There is a need to maintain the variety of suppliers as having only a single supplier for a component runs the risk of a demand for that component not being met and the risk that the technology for the component may move on while a current supplier's technology remains unchanged. Obtaining various components from different suppliers bears the problem that not all of the components are guaranteed to operate in an identical manner. Manufacturing tolerances often result in the obtained components having different performances. In the case of a flat panel display such as, for example, an LCD panel, these manufacturing performance differences may manifest themselves in colour variations as between LCD panels. This is clearly undesirable from the perspective of the original design manufacturer.

Abstract: The present invention relates to a method of filtering edges of a picture block with an edge-smoothing filter. The selection of the edge-smoothing filter depends on the size of the movement vector associated with each picture block BV to clarify the picture image and increase image quality. Alternatively, the selection of the edge-smoothing filter depends on the picture quality or both picture quality and the movement vector.
