N2 - This paper presents an efficient motion adaptive de-interlacing technique that consists of two main steps, i.e. 4-field extended Gaussian filtering motion detection and adjustable window ELA de-interlacing. Four consecutive interlaced fields are used to detect motion accurately. With a Gaussian filter, the motion detection can eliminate the influence of noise. An adjustable window ELA de-interlacing is adopt to process motion pixels, which can reconstruct image with high quality even in areas with horizontal edge and texture. Experimental results show that the proposed algorithm outperforms previous methods both objectively and subjectively. Based on our method, the high speed VLSI architecture has been designed and implemented. The operating frequency of the chip is 126MHz that it could process format conversion in real-time for both SDTV and HDTV applications.
