抄録

映像はただ映せばよいというものではない.映像から受ける印象は,撮影対象だけでなく,映像の表現方法にも影響される.テレビ会議システムにおいても,映像の表現方法を考えるべきであり,またその効果的な利用が望まれる.そこでいくつかの映像要素の組合せによる複数の映像を比較評価する実験を行い,映像表現がテレビ会議映像の印象に与える影響を調べた.10種類の映像についての,207人の大学生による質問紙評価の結果を,各映像の特徴,映像要素と各質問項目の評価の関係,質問項目の妥当性と映像の評価基準の観点から分析した.そして,会議の種類に応じた映像表現の利用について検討した.The impression of video varies depending on its expression.Thus expression of video should be taken into account when designing a videoconferencing system.Effects of video expression can possibly be used to improve videoconferencing if applied appropriately.An experiment to examine the effects of visual elements to videoconferencing was conducted.10 videos were shown to 207 college students and were evaluated by questionnaires.Then analyses were made to examine the characteristics of each video,the relation between the visual elements and the ratings of the questions,the validity of the questions,and the criteria of evaluating the video.As a result,principles to use appropriate video expression according to a type of meeting were suggested.

The impression of video varies depending on its expression. Thus expression of video should be taken into account when designing a videoconferencing system. Effects of video expression can possibly be used to improve videoconferencing if applied appropriately. An experiment to examine the effects of visual elements to videoconferencing was conducted. 10 videos were shown to 207 college students and were evaluated by questionnaires. Then analyses were made to examine the characteristics of each video, the relation between the visual elements and the ratings of the questions, the validity of the questions, and the criteria of evaluating the video. As a result, principles to use appropriate video expression according to a type of meeting were suggested.
