Abstract
A method of determining a value for a particular pixel of a particular image being temporarily located intermediate a first image and a second image is disclosed. The method comprises: computing a first motion vector difference on basis of a first (Dp) and second (Dpp) motion vector of a first motion vector field (D3(x, n−1)) corresponding to the first image; computing a second motion vector difference on basis of a third (Dn) and fourth (Dnn) motion vector of a second motion vector field (D3(x, n)) corresponding to the second image; and establishing the value of the particular pixel on basis of a first value of a first pixel of the first image if the first motion vector difference is smaller than the second motion vector difference and establishing the value of the particular pixel on basis of a second value of a second pixel of the second image if the second motion vector difference is smaller than the first motion vector difference.
