HDR显示性能测量研究

Measurement methods research for HDR display performance

介绍了国际标准认可的高动态(HDR)曲线(含PQ和HLG曲线)的技术特点和原理,分析为实现HDR显示,电视产品的技术实现。在此基础上,针对性提出HDR显示性能测量的关键项目,详细介绍测试信号、测量方法,分析现有测试结果。重点讨论对比度测量,给出不同测量方法的差异性和意义。

This paper introduces the specifications of the HDR curves（ including PQ and HLG curve） which are adopted by ITU standards,and analyzes the theories of TV which can display the HDR signal. On the basis of them,puts forward some key display performance items,and introduces testing signal and methods of measurements in detail. And then analyzes the test results. Discusses the methods of measurement focus on contrast,proposes several methods of measurement,and discusses the differences and importance among them.
