An interpolation unit (800) for computing an output pixel value of an output pixel of an output image on basis of input pixel values of a set of input pixels (101-114) being selected from an input image is disclosed. The interpolation unit (800) comprises: input pixel selection means (802) for selecting the input pixels, comprising a first group of pixels (101-107) and a second group of pixels (108-114); and order statistical filtering means (804) for determining the output pixel value on basis of the set of input pixels (101-114). The set of input pixels is characterized in that lines (115, 116) connecting pairs of input pixels (103, 113) being formed by respective input pixels of the first group of pixels (101-107) and the second group of pixels (108-114) intersect at a position (100) in the particular input image corresponding to a position in the output image where the output pixel is located. ® KIPO & WIPO 2007
