Abstract
In a method and apparatus for motion-vector-aided interpolation of a pixel in an intermediate image lying temporally or spatially between first and second images, motion vectors are assigned to the pixel to be interpolated, one pixel in each image being assigned to each vector. Video information values (e.g., luminance or chrominance values) are determined based on the video information values of pixels assigned to the motion vectors. A further video information value is generated by mixing certain of the video information values, and other video information values form a value interval, the mathematical position of the further video information value being determined relative to the interval boundaries. The video information value to be interpolated is determined depending on the position of the further video information value relative to the interval boundaries.
