Both the motion-detection and intra-field interpolation filter are important factors affect the efficiency of motion adaptive de-interlacing. New accurate motion detection (AMD) algorithm is proposed to improve the accuracy of motion detection, which reduces the possibility of error motion detection with a median filter. To improve the efficiency of intra-field interpolation deinterlacing in moving regions, an anti-aliasing interpolation filter (AAIF) is proposed, which is better than the

... l windowed sinc function. The simulation results show that peak signal noise ratio(PSNR) of our proposed deinterlacing method is 0.5-7.5 dB higher than that of previous studies and attains the best quality of subjective view 1 .
