Abstract (in Japanese) (See Japanese page) 
(in English) We experimentally evaluated the effect of high dynamic range on mental and physical workloads during contents viewing, including various types of content, on a 58-inch 4K TV. As the measurements items, subjectivity assessment, blinking rates, heart rate variability(the level of sympathetic nerve activity: LF/HF), near-infrared spectroscopic (NIRS) topography were adopted. The results showed that the scores for“presence”and “clear” when viewing 4K-HDR video content were significantly higher than those for 4K-SDR content. Moreover, the results indicate that NIRS(O2Hb), representing nervous system activity, when viewing 4K-HDR video content, was higher than those for 4K-SDR content, although it depended on the type of content. Moreover, HF/(LF+HF), representing parasympathetic nervous system activities, when viewing 4K-HDR video content, was significantly higher than those for 4K-SDR content.
