Perceptual Visual Quality of UHD-2/8K on Consumer Display

Description:

We performed a human-subject study on the perceptual visual quality of 8K resolution on consumer display devices. With the experimental setup simulating practical media consumption scenarios via TVs, we conducted subjective picture quality comparison tests between 8K and its predecessor, 4K. Here, we considered several factors about the user (e.g., visual acuity) and their underlying context (e.g., viewing distance). Statistical analysis of the collected experimental data confirmed that people could discern 8K against 4K after watching a short video and perceive 8K to have more clarity than 4K, even on a still image. We also found that human perception of 8K's visual quality depends on user characteristics (e.g., age) and contextual (e.g., content) factors. Last, we analyzed the test video clips to extract key features contributing to the most perceivable 8K content.
