This paper proposes a new motion estimation method for video format conversion. The algorithm uses improved three- step block-matching （TSS） algorithm, and corrects the motion vector by using zero detection and vector filter. In addition, the hardware implement architecture is based on DDA algorithm. Finally, it is validated by FPGA.
