摘　　要：随着高动态范围(HDR)显示技术的发展,人们越来越关注观看HDR影像的视觉舒适度问题。此前有研究指出,如果在黑暗环境中观看高亮度HDR影像容易引发观众视觉不适的症状,在观看环境中提供适当的环境光照明,可以缓解这种视觉不适症状。本文通过视觉舒适度量化评价方法,研究HDR影像画面平均亮度、画面亮度分布和镜头间亮度跳跃等因素对视觉舒适度的影响,以及HDR影像亮度与环境光照度的关系,给出适宜的环境光照度范围,为HDR影像制作和播放环境配置提供参考。With the development of HDR display technology,people are paying more attention to the issue of visual com⁃fort when watching HDR images.Previous studies have pointed out that viewing high brightness HDR images in a dark en⁃vironment can cause visual discomfort symptoms in viewers.Providing appropriate ambient lighting in the viewing environ⁃ment can alleviate these visual discomfort symptoms.In this paper we use a visual comfort quantification evaluation method to study the effects of factors such as average brightness of HDR image frames,brightness distribution of frames,and brightness difference between shots on visual comfort,as well as the relationship between HDR image brightness and ambient lighting levels.It provides a suitable range of ambient lighting levels as a reference for HDR image production and playback environment configuration.
