摘要
在视频显示系统中,定标器(scaler)起着匹配视频输出设备和视频显示设备之间的显示分辨率的作用,它直接影响了图像缩放之后的显示效果。本文采用双线性插值(bilinear interpolation)算法,在FPGA上实现了定标器,最后给出了验证平台和方法,结果表明所设计的定标器有效并且显示效果良好。
The scaler plays the role of matching the display resolution between video output devices and video display devices in the video display system. It affects the display quality after the image scaling directly.This paper introduces the bilinear interpo- lation algorithm and realizes the scaler with the FPGA.A verification platform and method are showed at the end. The results show that the scaler is effective and with good display quality.
