Patent ID: 7974342

Claim:
A motion-compensated image signal interpolation unit for generating an interpolated image intermediate a first image and a second image, the interpolated image being located at a first predetermined temporal distance (α) from the first image and being located at a second predetermined temporal distance (1−α) from the second image, the interpolation unit comprising: a motion estimation unit for furnishing a first motion vector and a second motion vector relating to the first image and the second image, respectively; a first sample generation unit generating a first group of samples based on the values of the pixels in the first image, the first motion vector and a first quotient wherein the first quotient is equal to a first spatial distance between a first one of the samples of the first group of samples and a second one of the samples of the first group of samples and the first predetermined temporal distance (α); a second sample generation unit generating a second group of samples based on the values of the pixels in the second image, the second motion vector and a second quotient wherein the second quotient is equal to a second spatial distance between a first one of the samples of the second group of samples and a second one of the samples of the second group of samples and the second predetermined temporal distance (1−α); and a filter that ordered statistical filters the samples of the first and the second group to produce a first value of a first pixel of the interpolated image, whereby the first quotient is substantially equal to the second quotient.
