摘要：In the field of VR systems, the AR technology is a topic. And so, beyond the conventional understanding that “high resolution” is equal to “high quality” of images desplayed on a CRT display, we are conducting basic research on technologies needed to develop an extra-high-quality imaging system, one that can convey high-order sensations, which convey deep artistic and emotional information. We designed an objective test for assessing extra-high-quality images that focuses more on high-order sensations than do subjective tests. An extra-high-quality imaging system is characterized by 4096 quantization levels for each R, G, and B. We assessed image quality by changing the quantization levels. The objective test was administered using electroencephalography (EEG). We found that the power of alpha-EEG was higher in images with a higher quantization level, meaning that EEG should create a good index for assessing the high-order sensations in extra-high-quality images.
