10.1 RGB Color Space Definition

In this Specification, the abbreviation RGB means the nonlinear sR’G’B’ color space in 8-bit representation based on the definition of sRGB in IEC 61966.
The 8-bit representation results as RGB888. The conversion to the more commonly used RGB565 format is achieved by scaling the 8-bit values to five bits (blue and red) and six bits (green). The scaling can be done either by simply dropping the LSBs or rounding.

在本规范中，缩写RGB是指基于IEC 61966中sRGB定义的8位表示的非线性sR’ g ’ b '颜色空间。
8位表示结果为RGB888。转换到更常用的RGB565格式是通过将8位值缩放为5位(蓝色和红色)和6位(绿色)来实现的。可以通过简单地删除lsb或舍入来实现缩放。

10.2 YUV Color Space Definition

In this Specification, the abbreviation YUV refers to the 8-bit gamma corrected Y’CBCR color space defined in ITU-R BT601.4.

在本规范中，简称YUV指ITU-R BT601.4中定义的8位伽马校正Y’CBCR颜色空间。
