cd/m2 – The candela (cd) is the base unit of luminous intensity in the International System of Units (SI); that is, luminous power per unit solid angle emitted by a point light source in a particular direction. A common wax candle emits light with a luminous intensity of roughly one candela.
cd / m2 –坎德拉（cd）是国际单位制（SI）中的发光强度基本单位；也就是说，点光源沿特定方向发射的每单位立体角的发光功率。一根普通的蜡烛发出的光的发光强度约为一个坎德拉。
Nits – A non-SI unit used to describe the luminance. 1 Nit = 1 cd/m2.
Nits –用于描述亮度的非SI单位。 1 Nit = 1 cd / m2。
HDR – High Dynamic range. It is a technology that improves the brightness & contrast range in an image (up to 10,000 cd/m2)
HDR –高动态范围。这项技术可改善图像的亮度和对比度范围（最高10,000 cd / m2）
SDR – Standard Dynamic range. It refers to the brightness/contrast range that is usually available in regular, non-HDR televisions usually with range of up to 100 cd/m2. This term came into existence after HDR was introduced
SDR-标准动态范围它指的是通常在非HDR电视中通常可达到的最大cd / m2范围内的亮度/对比度范围。引入HDR后，这个术语就存在了
WCG – Wide Color Gamut. Color gamut that offer a wider range of colors than BT.709. DCI-P3 and BT.2020 are examples of WCG offering more realistic representation of images on display devices.
WCG –宽色域。色域比BT.709提供更广泛的颜色。 DCI-P3和BT.2020是WCG的示例，可在显示设备上提供更逼真的图像表示。
EOTF – electro-optical transfer function. A mathematical transfer function that describes how digital values will be converted to light on a display device.
EOTF-电光传递函数，数学传递函数，描述如何将数字值转换为显示设备上的光。
OETF – optical-electro transfer function. A mathematical transfer function that describes how the light values will be converted to digital values typically within cameras.
OETF –光电传递函数。数学传递函数，描述通常在相机内如何将光值转换为数字值。
OOTF – opto-optical transfer function. This transfer function compensates for the difference in tonal perception between the environment of the camera and that of the display.
OOTF –光学传递函数。该传递函数补偿了照相机环境和显示器环境之间的色调感知差异。
PQ – PQ (or Perceptual Quantizer) is a transfer function devised to represent the wide brightness range (up to 10,000 Nits) in HDR devices.
PQ – PQ（或感知量化器）是一种传递函数，旨在表示HDR设备中的宽亮度范围（高达10,000 Nits）。
HLG – HLG (or Hybrid Log Gamma) is a transfer function devised to represent the wide brightness range in HDR devices. HLG is quite compatible with existing SDR devices in the SDR range.
HLG – HLG（或混合对数伽马）是一种传递函数，旨在代表HDR设备的宽亮度范围。 HLG与SDR范围内的现有SDR设备完全兼容。
