In this paper, a method of estimating true motion vectors to reduce image quality deterioration such as block artifact is proposed. Three consecutive original input images are used to calculate the motion vectors. Bi-directional motion estimation, forward directional motion estimation, backward directional motion estimation is performed. The minimum SSD(Sum of Square Difference) obtained by bi-directional motion estimation compares each of the SSD values obtained by motion estimation of the forward and backward direction. And this will determine the optimal MV of forward, backward direction. Then, the estimated true motion vector is applied to frame interpolation.
