面向超高清电视的主观评价测试图像序列研究

Materials design method for subjective evaluation of UHDTV

超高清技术的突破推动了超高清电视(UHDTV)的发展,使之逐渐具备高亮度、宽色域和高动态范围等特点。为了实现更科学、合理的主观评价测试,本文探讨超高清电视终端显示特性及影响因素,开展了面向超高清电视画质质量主观评价的测试图像序列研究,设计了覆盖画质清晰度、色彩表现力、运动效果等方面共13个测试项目的测试序列,提出测试图像素材选取建议,形成测试图像序列示例。经主观评价测试验证,本文设计的测试序列被证明具备实用性,为超高清电视主观评价技术发展和标准工作提供测试源支撑,同时有助于超高清电视画质质量提升。

The breakthrough of ultra-high-definition technology promotes the development of ultra-high-definition television(UHDTV),which gradually realizes the characteristics of high brightness,wide color gamut,and high dynamic range.To achieve a more scientific and reasonable subjective evaluation,the display characteristics and influencing factors of UHDTV has been discussed.In this paper,the research on the UHDTV test materials design method for subjective evaluation,13 test items including picture quality clarity,color expression,motion effect,etc.have been designed.Additionally,this paper provides suggestions for the selection of test image sequence materials,and formed examples of test image materials.The subjective evaluation verifies that the image sequence materials are practical,which provides test source for the subjective evaluation development and standard work of UHDTV,and helps to improve the quality of UHDTV.
