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： A method for testing a motion vector is described, which has: provision of at least one item of motion information assigned to the image sequence; storing a first image section of the first image in a first buffer memory and storing a second image section of the second image in a second intermediate memory, whereby a position of the first image section in the first image and a position of the second image section in the second image have reciprocal offset, which is dependent on the at least one item of motion information; determining a first image block in the first image section and a second image block in a second image section using the motion vector; comparing the contents of the first and of the second image block.

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： Method for motion-vector-aided interpolation of a pixel of an intermediate image lying between two input images includes a first pixel being selected from a first field and a second pixel being selected from a second field using a first motion vector, and a third pixel being selected from the first field and a fourth pixel being selected from the second field using a second motion vector. Next, an interval specified by video information values of the first pixel and the second pixel or an interval specified by video information values of the third pixel and the fourth pixel is determined and the video information values are mixed such that the video information value of the pixel to be interpolated lies within this interval.
