In the October 2015 issue of CGWORLD, the second special feature on video production under the BT.2020 standard, I wrote about the reality of video based on cognition in the section “Reality of Video Based on Cognition.
“High-reality Video Production in BT.2020: Cognition-based Visual Reality”
Abstract：
Next generation formats such as high resolution (4K and 8K), high frame rate (HFR) and high brightness (HDR) bring a high level of reality to video expression. In this talk, we will explain various visual effects and artifacts recognized in high quality video production, such as Hyper Acuity, which is an example of vernier vision, smearing caused by gaze movement after moving objects, and the trade-off relationship between image quality degradation and jerkiness, with reference to the relationship between video and human perception revealed by leading Japanese researchers. We then propose a psychophysical workflow based on those visual characteristics.
・Introduction：Broadcast and cinema video standards
・Resolution：Spatial resolution research and human cognition
・ High Frame Rate：High frame rate effects and possibilities
・ Color Gamut & HDR：Color gamut and high dynamic range
・ Conclusion：Toward High-Reality Video Production under the BT.2020 Standard
