摘要：A motion-compensated image signal interpolation unit () for generating aninterpolated image being located at a first predetermined temporal distance (a) from thefirst image and being located at a second predetermined temporal distance (1−a) from
the second image is disclosed. The interpolation unit () comprises: motion estimationmeans () for furnishing a first and a second motion vector relating to the first and secondimage; furnishing means () for furnishing a first group of samples on basis of values ofpixels of the first image and the first motion vector and for furnishing a second group ofsamples on basis of values of pixels of the second image and the second motion vector,and filtering means () for ordered statistical filtering of the samples of the first and thesecond group to produce a first value of a first pixel of the interpolated image (),whereby a first quotient is substantially equal to a second quotient, the first quotientbeing determined by a first spatial distance (x) between a first one of the samples of thefirst 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 secondspatial distance (x) between a first one of the samples of the second group and a secondone of the samples of the second group and the second predetermined temporaldistance (1−α).
