色彩空间分为：RGB、YUV、HSV

RGB中分为：RGB24（888）、RGB16(565)

YUV中分为：YUV444、YUV422、YUV420、YUV411、NV12、NV21、YVU420

另外还有一种以FOURCC规范命名的方式：

• UYVY (YUV422, U-Y-V-Y, progressive, packed)
• UYNV (same as UYVY )
• Y422 (same as UYVY )
• IUYV ( YUV422, U-Y-V-Y, interlaced, packed)
• YUYV (YUV422, Y-U-Y-V, progressive, packed)
• YUNV (same as YUYV)
• V422 (same as YUYV)
• YUY2 (same as YUYV)
• YVYU (YUV422, Y-V-Y-U, progressive, packed)
• IYU2 ( YUV444, U-Y-V, progressive, packed)
• YV16 (YUV422, Y-U-V, progressive, planar)
• YV12 (YUV420, Y-V-U, progressive, planar)
• IYUV (YUV420, Y-U-V, progressive, planar)
• I420 (same as IYUV)
