摘　　要：对于不同显示面板,当输入同一视频源且不对视频源进行预处理时,无法做到视频的高质量、不失真显示,为解决同一视频在不同显示面板显示效果不一致的问题,本文设计了一种通过对显示面板底层的各种物理参数进行调整,使得用户可以自定义实现对显示画面的补偿、矫正和增强的图像处理方法。该方法运用Xilinx Spartan 6芯片,通过Gamma校正、对比度和亮度调整、显示屏几何校正,对分辨率为1280*800的显示屏实现刷新率为60 Hz的24位真彩色的图像进行实时处理。经测试,本系统各功能均能正常实现,并且最多可满足分辨率FHD1920*1080@60Hz的显示要求。For different display panels,when the same video source is input and the video source is not preprocessed,the high quality and undistorted display of the video cannot be achieved.To solve the problem that the same video is inconsistent display effect in different display panels,this paper designs a kind of By adjusting various physical parameters of the underlying layer of the display panel,the user can customize the image processing method for compensating,correcting and enhancing the display screen.The method uses the Xilinx Spartan 6 chip to perform real-time processing of 24-bit true-color images with a refresh rate of 60 Hz on a display with a resolution of 1280*800 through Gamma correction,contrast and brightness adjustment,and display geometry correction.After testing,all functions of the system can be realized normally,and can meet the display requirements of resolution FHD1920*1080@60 Hz.
