摘　　要：视频格式转换是当前数字化处理电视和新一代的全数字电视中一项重要的技术。把具有图像边缘保持特性的降噪滤波器与运动自适应的逐行插补算法相结合 ,提出一种新的视频格式转换算法 ,并进一步讨论该算法硬件实现的原理和结构。文中所提出的算法已用FPGA芯片实现 ,实验结果表明该算法十分有效。Along with the development of digital processing TV and new generation TV fully digitalized, video scan format conversion has become an important technology. In this paper, by incorporateing noise\|reduced filter with edge\|preserved into motion adaptive deinterlacing algorithm, a new algorithm for scan format conversion is proposed. The principle and structure for implementing this algorithm in hardware are discussed. Accordingly, the simulation experiment in FPGA (Field\|Programmable Gate Arrays) is designed. The experimental results show that the algorithm proposed in the paper is very efficient. [
