我是非计算机专业的大学生，现在正在做关于机器人视觉的项目，需要从图象采集卡的数据中识辨目标，现有几个关于YUV的问题想请教，不知哪

Question

我用的是大恒产的图像采集卡DH-CG400.、我现在从一个CVIEW继承的类中使用

         COLORREF m_RGB;
         CDC* pDC=GetDC();
m_RGB=pDC->GetPixel(point);
      
        得到RGB，但如何用语句直接得到YUV的数值？上次有人告述我YUV的值可以直接从卡中得到，但是没有算法，能否给出具体步骤我现在很急，请高人相助，小弟感激不禁！

Answer 2

YUV和RGB不有转化关系吗？用这个转化关系不就ok了
