Comparison of Healing Effect on Biomedical Signals by the Difference of Color Gamut and Dynamic Range When Viewing Nature Images

The quality of images has improved remarkably, and video standards that provide a strong sense of reality like BT.2020 and BT.2100 have been put into practical use. Because, we believe that viewers experience a healing effect when viewing high-definition images, we focused on color gamut and dynamic range, which affect image quality. We examined biomedical signals under different color gamut and dynamic range when viewing nature images, and we analyzed the healing effect induced by high-definition images.
