摘要:
A motion-compensated image signal interpolation unit (200) for generating an interpolated image being located at a first predetermined temporal distance (a) from the first image and being located at a second predetermined temporal distance (1−a) from the second image is disclosed. The interpolation unit (200) comprises: motion estimation means (202) for furnishing a first and a second motion vector relating to the first and second image; furnishing means (204, 206) for furnishing a first group of samples on basis of values of pixels of the first image and the first motion vector and for furnishing a second group of samples on basis of values of pixels of the second image and the second motion vector, and filtering means (212) for ordered statistical filtering of the samples of the first and the second group to produce a first value of a first pixel of the interpolated image (102), whereby a first quotient is substantially equal to a second quotient, the first quotient being determined by a first spatial distance (x1) between a first one of the samples of the first group and a second one of the samples of the first group and the first predetermined temporal distance (α), the second quotient being determined by a second spatial distance (x2) between a first one of the samples of the second group and a second one of the samples of the second group and the second predetermined temporal distance (1−α).
