A positioning system for a vehicle includes a camera, a processor unit and a data storage device. A length relating to a feature of the vehicle is stored in the data storage device. The vehicle is positioned for an inductive charging process in that the vehicle is recorded by a camera and a feature of the vehicle is detected. The position relating to a feature is calculated.

Positioning system and method for positioning a vehicle

Plasma Display Panels (PDP) are becoming more and more interesting for TV technology. Due to the larger size of PDPs, with larger viewing angle the large area flicker effect will become more serious in the future, in particular when handling 50 Hz video standards. This invention proposes a different sub-field organisation, with different coding, which reduces large area flicker artefact, and which is characterised by:

Method and apparatus for processing video pictures, in particular for large area flicker effect reduction

Plasma Display Panels (PDP) are becoming more and more interesting for TV technology. Due to the larger size of PDPs, with larger viewing angle the large area flicker effect will become more serious in the future, in particular when handling 50 Hz video standards. This invention proposes a different sub-field organisation, with different coding, which reduces large area flicker artefact, and which includes grouping of sub-fields in two sub-field groups wherein the two sub-field groups are identical in terms of the most significant sub-fields and different in terms of the least significant sub-fields, and a sub-field coding process that distributes luminance weight symmetrically over the two sub-field groups so as to minimize the large area flicker luminance component.

Method and apparatus for processing video pictures, especially for false contour effect compensation

With the new plasma display panel technology new kinds of artefacts can occur in video pictures. These artefacts are commonly described as &ldquo;dynamic false contour effect&rdquo;, since they correspond to disturbances of gray levels and colors in the form of an apparition of colored edges in the picture when the observation point on the PDP screen moves. According to the invention, such an artefact is compensated by analyzing the motion in the pictures, assigning to each block of a picture a corresponding motion vector and performing a re-coding step in which the different sub-fields of a pixel are shifted to distribute the sub-fields of a pixel more closely on the eye trajectory.
