Abstract:
At present, although 4K TV sets are available in the market, the provision of 4K TV content is still not
sufficient. Almost all TV content is in high-definition television (HDTV) broadcasting, and images/videos
with insufficient resolution are up-converted to the resolution of the display. Thus, almost all 4K TV sets are
equipped with super-resolution (SR) technology to improve the resolution of the content. However, the
performance of SR on TV sets has not been guaranteed. Although the capability of SR needs to be assessed,
there has been no standard method for such an assessment. In this paper, a subjective assessment method for
multiple displays is proposed. Subjective assessment experiments of displays with and without SR are
conducted to confirm the ability of an SR method. As the results of statistical analysis, the superiority of the
SR in resolution quality is proved by the significant differences indicating the reproducible results. As the
reproducible results are obtainable
, the proposed method is useful to assess multiple displays. In this paper,
the methodology of the proposed assessment method is described and the experimental results are presented.
