    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： A method for reducing image artifacts in an image that includes a number of pixels each of which includes at least one video information value, includes generating a plurality of filter coefficients for at least some of the pixels of the image, on the basis of which the video information values of the pixels can be reconstructed. Artifact detection is performed to detect artifact regions within the image. At least some filter coefficients of those pixels that lie within the artifact regions are modified to generate modified filter coefficients. The video information values are synthesized using the filter coefficients, the modified filter coefficients being employed for the synthesis for pixels lying within the artifact regions.

    摘要： A method for encoding first and second data words, which may represent differential data values (e.g., luminance and chrominance difference data values), onto an encoded data word includes: assigning a first code word to a first approximation value for a first data value, and assigning a second code word to second approximation value for a second data value; mapping the first and the second code words onto respective first and second data segments of the encoded data word; determining a first difference value between the first data value and the first approximation value and determining a second difference value between the second data value and the second approximation value; and at least partial mapping a first difference data word representing the first difference value and/or a second difference data word representing the second difference value onto at least one additional data segment of the encoded data word.

    摘要： An image to be interpolated is subdivided into a number of image blocks and a motion estimation technique is implemented to provide at least one initial motion vector for each of the image blocks. A modified motion vector is generated for each image block based on the initial motion vectors assigned to the individual image blocks. At least one additional image block is determined through which the motion vector assigned to the given image block passes at least partially, and the modified motion vector is generated as a function of the initial motion vector that is assigned to this at least one additional image block.

    摘要： A method for processing a video image sequence with a number of successive images and an image processing device for processing a video image sequence are described. The method comprises: generation of at least one scaled image sequence (F11, F12) from the video image sequence (F); generation of a motion-compensated scaled image sequence (F40) from the scaled image sequence (F50); generation of a motion-compensated output image sequence (F′) from the scaled image sequence (F40); wherein the generation of the motion-compensated scaled image sequence (F40) comprises the determination of a motion vector field based on at least two images (F11n−1; F11n) of the scaled image sequence (F11, F12) and the interpolation of an image using the at least two images and the motion vector field, and wherein the at least one input scaling factor (S11, S12) is dependent on motion information that is represented by at least one motion vector field that was determined for the temporally preceding images of the at least one scaled image sequence (F11, F12).
