視聴者の身体に悪影響を及ぼす恐れのある画面動揺を含んだ映像について,その不快度を推定する方法をこれまで研究開発し,推定精度の改善を図ってきた.
今回,これまで対象としてきた視野サイズの2K,4Kに,より広視野の8Kを加えた上で,複数の動揺領域の目立ちやすさと位置関係を変え,知覚される動揺の大きさである「動揺認知量」と不快度を調べる評価実験を行った.
その結果,視野サイズおよび動揺領域間距離によって動揺認知量と不快度との乖離がどのように変化するのか明らかになった. |

The author has developed methods to estimate the unpleasantness degree of shaking images which should cause a certain harmful influence on viewers’ body, and improved the precision of the estimation.
This time, the author carried out a series of experiments, with which the psychological index for quantity of shakiness named "cognition degree of shakiness" and the unpleasantness degree were evaluated in various conditions; the viewing area sizes were expanded to extra wide-field 8K adding to the previous sizes of 2K and 4K, and the different saliency and locations of some shaking areas were combined.
As the result, it was revealed how the divergence between the cognition degree of shakiness and the unpleasantness degree changes by the viewing area size and the distance between shaking areas. |
