| Abstract(in English) | The aspect ratios suitable for appreciating the ultra high-definition and wide-screen images were examined. First, the preferences for the images with four aspect ratios were compared with that for the 9:16 image. It was found that the preferred aspect ratio depended on the screen size but not on the viewing angles. For approximately 60-in.size, the 9:16 or 1:2 aspect ratio was preferred most and for 90-120-in.size, the 1:2 was preferred most. Then, the degrees of "Potency" and "Comfortableness" from the images with four aspect ratios were compared with those from the 9:16 image. It was found that the degree of "Potency" for the images shot with narrow camera angles increased as the aspect ratio got smaller. The results for "Comfortableness" had high positive correlation with those for preference. |
