For improving motion portrayal and reducing undesirable artifacts, e.g., double images and 'mouse teeth' structure, each pixel of intermediate fields in a field rate up-conversion system is determined from nearby pixels in the existing fields using an adaptive linear filtering method (or apparatus) which provides: calculation of sums of differences (one or more for each pixel involved in the adaptive filter); calculation of basic coefficients (one for each pixel involved in the adaptive filter); one-dimensional median filtering of the coefficients; two-dimensional linear filtering of coefficients; normalization of coefficients; calculation of main interpolated pixel values; and correction of interpolation in the case of fast motion.
