This paper proposes a motion estimation algorithm based on time-recursive motion vector to reduce calculation amount. It also presents an improved VOD matching function (IVOD) which can make accurate matching under illumination intensity change scene. The motion estimation algorithm is applied to the Frame Rate Up-conversion system and the experimental results show that the proposed algorithm maintains satisfactory visual quality and PSNR. And IVOD matching function can overcome the effects of illumination intensity change to find the best matching block.
