The YUV color model is used to analyze the relative luminance values of various LED pixels, to screen and record each LED pixel that luminance are not uniform;
采用YUV颜色模型，分析了各LED像素点的相对亮度值，对亮度不一致的像素点进行筛选与记录；
At the same time, the array of three values simplifies the complexity in the image, so even if a video is of poor quality or a different hue, the information about its relative luminance is retained.
同时，三种数值的排列简化了图片的复杂性，所以即使一个视频质量差或色相不一，关于视频的相对亮度信息还能保留。
