Abstract
A video decoding and display system uses temporal post-processing to smooth motion in a displayed moving image. The temporal post-processing uses motion vectors each of which indicates visually similar areas, in first and second frames to generate interpolated motion vectors which match areas in an interpolated frame to visually similar areas in the first and second frames. In one embodiment, each component of each motion vector is divided by two and used to generate an interpolated frame half way between the first and second frames. Display of the first and second frames are delayed so that the interpolated frame is displayed at a time half way between the display times of the first and second frames.
