    摘要: A method for detecting a video signal that represents an image sequence and exhibits linewise repeated video data comprises selecting a plurality of line groups each having a first, a second and a third line, which originate from two consecutive fields in the case of a field sequence and from one field in the case of a frame sequence. The method determines for each line group a first line-distance measure for a difference between video contents of the first and second lines and a second line-distance measure for a difference between video contents of the second and third lines. The method then interprets the first and second line-distance measures with regard to the presence of a significant difference between these line-distance measures.

    摘要: Virtually complete freedom from flicker is achieved by converting a line-interlaced 50/60 Hz video signal to a progressive 100/120 Hz video signal. For this purpose, the video signal on the input side is first converted to a 100/120 Hz signal with line-interlaced fields, and the progressive video signal is then produced from the first converted signal taken together with the non-converted input signal.

    摘要: In a method and device for determining motion vectors that are each coordinated with individual regions of an image, the image is divided into a number of first main blocks, making use of a first block raster, and a first estimation process is performed to provide each first block with a motion vector. The image is also divided into a number of second main blocks, making use of a second block raster, whose position is displaced relative to or offset from the first block raster, for example in the horizontal and vertical directions, and a second estimation process is performed to provide each second main block with a motion vector. A number of subblocks are formed, each subblock being formed by an overlap region between one of the main blocks of the first raster and certain ones of the second main blocks of the second raster. A motion vector for each subblock is generated, this motion vector depending on the motion vectors of the main blocks and being coordinated with the particular subblock.

    摘要: An image sequence includes consecutive video images each exhibiting at least one image region having a number of pixels, where each pixel includes at least one intensity value. For each image a motion measure value is determined indicative of temporal change of a video content of the image region and varying the intensity values of the pixels of the image region relative to the associated intensity values from video image to video image, a measure for the variation of the intensity values being dependent on the motion measure value determined and the change in the intensity values relative to the associated intensity values being greater the larger the motion represented by the motion measure value.
