1. A method of interpolating the pixel value of a selected pixel between temporally adjacent frames in a video sequence, comprising: determining a motion vector for the selected pixel in a frame a which is a time a ahead of F(t−1), wherein at least one of the endpoint pixels of the motion vector in F(t), pixel D, and F(t−1), pixel E, is detected to be a still pixel; assigning a still level, S, which ranges between a first value and a second value, different than the first, to characterize the degree of stillness of the at least one still pixel, wherein the first value represents a substantially non-still pixel and the second value represents a substantially still pixel; and adjusting the pixel value of the at least one still pixel as a function of its still level; wherein the pixel value of the selected pixel is calculated, at least in part, as a weighted average in a, of the pixel values of the endpoint pixels D and E.
