摘要：A motion-compensated image signal interpolation unit (200) 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) fromthe second image is disclosed. The interpolation unit (200) comprises: motion estimationmeans (202) for furnishing a first and a second motion vector relating to the first andsecond image; furnishing means (204, 206) for furnishing a first group of samples on basisof values of pixels of the first image and the first motion vector and for furnishing asecond group of samples on basis of values of pixels of the second image and the secondmotion vector; and filtering means (212) for ordered statistical filtering of the samples ofthe first and the second group to produce a first value of a first pixel of the interpolatedimage (102), whereby a first quotient is substantially equal to a second quotient, the firstquotient being determined by a first spatial distance (x,) between a first one of thesamples of the first group and a second one of the samples of the first group and thefirst predetermined temporal distance (a), the second quotient being determined by asecond spatial distance (x2) between a first one of the samples of the second group and asecond one of the samples of the second group and the second predetermined

temporal distance (1-α).
