Abstract:
1. A method for motion-vector-aided interpolation of a pixel in an intermediate image lying between a first image and a second image, comprising the steps of: assigning a first motion vector and a second motion vector to the pixel to be interpolated; assigning a first pixel in the first image to the first motion vector and assigning a second pixel in the second image to the second motion vector; determining a first video information value based on a video information value of the first pixel and determining a second video information value based on a video information value of the second pixel; determining a first further video information value based on a video information value of a third pixel at an initial point of the second motion vector in the first image and determining a second further video information value based on a video information value of a fourth pixel at a terminal point of the second motion vector in the second image; generating a third video information value by mixing the first and second further video information values; determining an interval having boundaries defined by the first and second video information values; determining a position of the third video information value relative to the interval boundaries; selecting the third video information value as a video information value of the interpolated pixel if the third video information value lies inside the interval boundaries; and determining a video information value of the interpolated pixel if the third video information value lies outside the interval boundaries, by
