| Outline of Final Research Achievements |
We examined the quality fo user experience measurement of 4 KTV using cerebral blood flow and muscle myoelectricity from various viewpoints. First, it was verified that objective evaluation of coding degradation can be performed by myoelectric information of the facial muscle when JPEG encoded HDTV still image is observed. Next, when presenting a still image to 4K · PC · iPhone with different pixel resolution of the display device, a significant difference was found in left and right temporal lobes (ch 2 and ch 16) with respect to "realistic feeling", and it was a correlation change between the types of display and cerebral blood flow. It was obtained that the correlation between the amount of change in cerebral blood flow and the subjective evaluation value due to the preference difference in the 4K 2 K still image was appeared the right temporal region (ch 6) of the frontal lobe.
