- Abstract
- The screen size and the resolution of the displays available to the consumer market have been steadily increasing. According to established vision science, there are limits to the human visual system for the perceptibility of resolution at typical viewing distances. This paper discusses a subjective evaluation that was performed to assess the perceptual difference between UHD-1/4K and UHD-2/8K for various types of content on an UHD-2/8K consumer display. It also performs a detailed frequency and visibility analysis of the content to determine the characteristics of the most perceptual content and establishes a relationship between the subjective test results and the vision science.

bio
Michael D. Smith has been a digital imaging and intellectual property consultant since 2003. He is currently the co-editor of the Joint Photographic Experts Group (JPEG) 2000 high-throughput image compression standard. In 2018, he received a screen credit for his work on Mary Poppins Returns which was related to the color science involved in integrating a traditional 2D animation workflow with a modern ACES production pipeline. From 2013 to 2015, he was the co-chair of Blu-ray Disc Association’s ultrahigh-definition task force (UHDTF) Video Subgroup, which defined the video-related requirements for the UHD Blu-ray disc format. His work on more than 35 intellectual property matters related to infringement and validity of patents has resulted in payments of approximately $1.7 billion. He was the editor of the book “3D Cinema and Television Technology: The First 100 Years” published by SMPTE in 2011. He received the BS and MS degrees in electrical engineering from the University of California at Los Angeles (UCLA), Los Angeles, CA, in 2001 and 2004, respectively.Michael Zinkbio
Michael Zink is the vice president of technology at Warner Bros. (WB), Burbank, CA, where he is responsible for exploring emerging technologies to enhance WB’s capabilities for production, post-production, and distribution. This includes assessing new technologies and assisting with the setup and integration of digital workflows. He also participates in a number of standards associations such as the Consumer Technology Association (CTA), Digital Cinema Initiatives (DCI), and SMPTE, among others, and also serves as the chairman for the Ultra High Definition Alliance (UHDA). Prior to joining WB, in 2014, he worked at Technicolor, London, U.K. and Los Angeles, CA, for more than ten years, most recently as the vice president of technology strategy, where he was responsible for launching the production efforts around various new optical disc formats. Additionally, he was responsible for the promotion and adoption of Technicolor technology solutions within industry groups. Earlier in his career, he worked for several media production facilities in Germany.Aansh Malikbio
Aansh Malik is an AI engineer with the Storytelling Technology Innovation and Content Standards Group at Warner Bros., Burbank, CA. His work focuses on leveraging advancements in AI to enable more interactive storytelling, facilitate experiences in immersive mediums such as AR/ VR, as well as augmenting current workflows in the media production lifecycle. His projects are a confluence of fields including reinforcement learning in game engines, computer vision, recurrent neural networks for audio processing, among others. He received the BS degree in electrical engineering, with a specialization in machine learning, from the University of California at San Diego (UCSD), San Diego, CA. - Keyword(s)
