摘　　要：为了解决视频格式上的差异,格式转换芯片已经成为显示器系统中不可或缺的关键器件.通过加权将具有边缘保持特性的中值滤波算法和时域上场间均值滤波算法相结合,同时考虑了硬件的可实现性和硬件资源的利用率,提出了一种运动自适应去隔行算法.该算法已经通过C模型和Xilinx FPGA验证,并应用于视频格式转换SOC芯片中,给出了该算法的硬件实现框图和系统性能.Due to the versatility of real-world video formats, format conversion has become indispensable in modern video display systems. A new motion adaptive de-interlacing algorithm is proposed which integrates edge-preserving median filtering algorithm and average fihering algorithm together by weight. It has advantages of easy implementation and high hardware utilization. This algorithm has been verified by C model and Xilinx FPGA and is applied in real-time video processing SOC. Morever, the hardware implementation block diagram and system performance are provided as well.
