リアルタイム4K/8K 超解像処理装置

4K/8K systems are expected to take over HDTV. Commercial 4K broadcasting has started and the 8K test broadcasting is planned next year. However it is very difficult to adjust the accurate focus with a small view finder on 4K/8K cameras. Although accurate focus is very important, it is not an easy task to accomplish therefore some of the 4K/8K content can be blurry. Analogue NTSC content is up-converted to HDTV format that is used for HDTV broadcasting even now. The up-converted content does not have sufficient resolution and is burry. Although 4K TV sets are equipped with Super Resolution (SR) technologies to cope with the blurry issues, none of the SR is actually able to fix it. SR algorithm with non-linear signal processing (NLSR) was proposed to fix the issues. NLSR is a simple algorithm and can work in real time for 4K/8K.
