摘要
本文用二维谱分析了现制式广播电视图像的缺陷，研究了用内插法实现逐行扫描或倍行扫描，以使图像得到较大改善。对自适应内插法进行了重点分析，并用硬件实现了该内插方法，得到较好的主观视觉效果。
A new method of interpolation for TV signal based on realtime motion detection are proposed and analysized by 2D spectrurn. This paper goes on to use this new method to realize progressive scanning or doubling scanning so that good picture quality can be achieved. It emphasizes on adaptive interpolation and uses hardware to perform the method. The method discussed in this paper gets good visual effect.
