用于视讯解交错的先进影像处理器

本文提出一种用于视讯解交错的先进影像处理器。因为影片模式来源和一般的电视交错影像必须分开处理，因此，采用了一种新颖的使用四个场缓冲器及层次架构的影片来源侦测方法，分离影片及交错的电视影像，以提高侦测正确率。针对电视影像的解交错，提出了一种新颖的、低成本的解交错方法，使用窗口扩展法侦测低角度边缘以去除锯齿，适应三维移动。仿真结果证实，采用该方法可获得极佳的影像画质。

Advanced Video/Image Processor for Deinterlacing

An advanced video/image processor for deinterlacing is proposed in this paper. Since video sources input to the video processor can be originally from film or from interlaced video, they must be handled separately. To improve the correction rate of detection, a novel method using four fields and layered structure is proposed. Also, a novel, cost effective, 3D motion-adaptive deinterlacer which includes the window-expanding search for removing the saw-tooth occurred on low-angle moving edges, is proposed, and, from the simulation results, good visual quality images can be obtained by using the proposed approach.
