摘要
在超高清的技术参数中,HDR是其中尤其重要的组成部分,它提供了更多的画面细节和层次,能够同时展现极亮和极暗的亮度范围,提供更好的"沉浸感";可在不同亮度级上提供更好的局部对比度,提升边缘锐度;搭配宽色域的扩展,可以提供丰富的色彩数量和更鲜亮的颜色。
HDR is a particularly important component of UHD technical parameters. It provides more details and layers of the image, as well as the extreme brightness and extreme darkness at the same time for better immersion. It also provides a better local contrast at different brightness levels, and enhances the edge sharpness. With a wide color gamut expansion, it presents a larger number of vivid colors.
