Real-time Super Resolution equipment for 8K video

Abstract

Resolution is one of the most important things when assessing image quality, and image quality improves in proportion to resolution. Super Resolution (SR) is a resolution improving technology that is different from conventional image enhancement methods. SR methods, of which there are many, typically have complex algorithms that involve iterations, and it is not easy to apply them to video running in real time at 50 or 60 frames a second; i.e., each frame would have to be processed in 20 ms (50 Hz) or 16.7 ms (60 Hz). In this paper, a simple form of SR that uses non-linear signal processing is proposed to cope with the difficulties in real-time processing. Real-time hardware equipped with an FPGA (Field Programmable Gate Array) for 4K and 8K video is shown and its SR capability is discussed.
