摄像头说明
摘要:YUV(亦称YCrCb)是被欧洲电视系统所采用的一种颜色编码方法(属于PAL)。YUV主要用于优化彩色视频信号的传输,使其向后兼容老式黑白电视。与R GB视频信号传输相比,它最大的优点在于只需占用极少的带宽(RGB要求三个独立的视频信号同时传输)。其中“Y”表示明亮度(Lumina nce或Luma),也就是灰阶值;而“U”和“V”表示的则是色度(Chrominance或Chroma),作用是描述影像色彩及饱和度,用于指定像素的颜色。“亮度”是通过R GB输入信号来创建的,方法是将RGB信号的特定部分叠加到一起。“色度”则定义了颜色的两个方面—色调与饱和度,分别用Cr和CB来表示。其中,C r
