Abstract: Currently, various television standards use different aspect ratios. For example, a wide screen aspect ratio of 16:9 is gaining popularity over the existing TV broadcasts that use 4:3 aspect ratio. A method of scaling an image horizontally with a uniform or non-uniform scaling ratio is referred to as “panoramic scaling”. A device 100 and method 800 of scaling an image 102 by means of a scaling function 121 that is generated on the basis of a motion vector 101 of at least a part of the image 102 is disclosed. The device 100 can be used in an image processing apparatus or in an image display apparatus for converting a first image with a first aspect ratio to a second image of a second aspect ratio. The disclosed device 100 is useful in reducing the visual distortion introduced by the panoramic scaling especially in case of moving objects in a scene.

Abstract: The invention relates to electronic equipment (2) capable of presenting a demonstration routine. The electronic equipment comprises a processing unit for receiving and processing a synchronization signal and a memory for storing a demonstration routine. The processing unit is adapted for presentation of the demonstration routine in accordance with the synchronization signal. A synchronous presentation of the demonstration routine may thereby be achieved on an ensemble of electronic equipment. In an embodiment the electronic equipment is an ensemble of TV-sets synchronously presenting an electronic sticker (3) overlaid on the display.

Abstract: The quality of recorded images with for example a high speed camera can be detoriated by light modulation which is a consequence of for example gas-discharge lamps running at a lower frequency with respect to the camera. A camera according to the invention provides light modulation removal by handling fields of the image different depending on the light modulation.

Abstract: Method and apparatus for dithering and undithering data words in a data stream. The method comprises the steps of processing a data word in a data stream to obtain an output data word by calculating (14) a first difference, calculating (16) a second difference, comparing (14, 16) the first difference and the second difference with a comparator value S, shifting left (12) the first data word with a first number of bits, the first number being equal to a shift value G minus one, and adding (18) an offset value D to the first data word only when both the first difference and the second difference are equal to the comparator value S. The apparatus comprises elements to perform the steps of the present method. The present method and apparatus allow using common steps, respectively elements to perform both dither and undither operations.

Abstract: The invention provides detecting a static area in video images wherein frame difference information (6) and displaced frame difference information (4) are calculated, and the static area is detected using the frame difference information (6) and the displaced frame difference information (4) in combination.
