Abstract :
Results of a subjective assessment of superresolution (SR) technology for 4K TV sets are reported. 4K TV sets are currently available in the market, and some are equipped with SR functionality. Recently, SR technology that uses nonlinear signal processing (NLSP) and can work in real time has been proposed. The proposed method can enhance images without enlargement. The subjective assessment was performed by comparing 4K videos with and without NLSP on 4K TV sets. The assessment method was a combination of Scheffe´s paired comparison and ITU-R BT.500. Assessment data were statistically analyzed, and the results proved that NLSP is superior in resolution.
