BT2020画质好。1、色域：BT2020是HDR（高动态范围）色域，目前顶级的OLED电视大概能覆盖个80%，BT709是SDR（标准动态范围）色域，色域超过100%BT709即为广色域电视。在色彩范围上，BT2020的色域范围比BT709更广。BT2020的色域可以达到100%的Rec.2020，而BT709的色域则是Rec.709的98%。因此，BT2020的...
这是佳能专业监视器的色域空间范围,可以看出,BT.2020/BT.709/Cinema Gamut三种不同的色域有着不同的色彩丰富程度,覆盖范围越大,色彩越丰富,但是,这是在专业监视器上才能实现的视觉感受,一般情况下没有专业参考级监视器,因而,我们制作的画面要根据影片的最终播放平台进行针对性选择不同的色域,加上前面提到的伽马曲线...

摘要: This paper describes our original BT. 709-to-BT. 2020 conversion technology, that enables color space conversion and gamut expansion. The technology has been evaluated using ITE's Ultra-high definition/wide-color-gamut standard test images.关键词:...
個人理解:HLG的色彩空間是BT2020的,slog2默認的是S-Gamut的,在HLG拍的視頻,視頻屬性是有標記BT2020的,但Slog2拍的就沒有,因此,在後期的時候,HLG並不需要手動把BT2020映射到BT709 普通色域(若要製作HDR,就要手動設定不改映射)。而Slog2 就需要通過套LUT slog2 to BT709。 不套LUT直接調slog2 之類的,會造...
这里的面积对比是基于native Gamut-原生色域,原生色域在测量rgb三种颜色的坐标并求得面积,对比某个基准得出来的就是色域范围,但中文翻译可能有很多种(色域容积、色彩量),我也不能确定哪个是正确的,有些叫法还代表有亮度坐标轴。广色域显示器应该具备切换到不同色域(色彩空间)的能力,不然会得到错误的颜色。
ITU-R BT.2020ARIB STD-B58We have successfully developed an 8K display with 120Hz frame rate, 12bit each RGB. The wide gamut has been expanded over 85% coverage ratio of ITU-R BT2020. Furthermore, the input interface has been upgraded to single optical fiber cable of 256Gbps which is ...
If they work in cinema, instead of buying a monitor, they will buy a DCI-P3 projector to further mimic how the video will be consumed and at the correct color gamut. 专业的调色师将购买专门为其工作的色彩空间设计的显示器。如果广播他们的所有作品,他们将购买专为100%与Rec.709色彩空间匹配的高...
