Abstract

Purpose: This study aimed to compare and assess whether there was a relation between self-reported symptom and stereopsis in viewing an anaglyph 3D and a general 2D image. Methods: Seventy subjects (38 males, 32 females) were students ranging in age from 20 to 30 years. Subjects' symptoms were investigated by a questionnaire after viewing the 2D image and the anaglyph 3D image using red-green glasses for 30 minutes. Titmus circles and TNO stereopsis tests were performed before and after the images. A correlation between symptom and stereopsis was evaluated. Results: Both ocular and nonocular symptom in viewing 3D image were higher than those in 2D image. Titmus circles stereopsises using polarized filters were not changed before and after viewing images, but TNO stereopsises using color filters such as red-green glasses were increased after viewing 3D image. Ocular symptom and TNO stereopsis were increased after viewing 3D image, and there was a good correlation between them (r=0.605). Conclusions: Better stereopsises before viewing 3D are relatively lower ocular symptoms in viewing 3D image. But symptoms are increased in viewing anaglyph 3D image for a short-time and improvement of TNO steropsis is poorly associated with the relief of ocular symptoms. This tendency seems to be related with an adaptation to anaglyph 3D image with red-green glasses.

목적: 일반 2D영상과 anaglyph 3D입체 영상을 시청했을 때 나타나는 자각 증상과 입체시 관련성을 비교 평가하고자 하였다. 방법: 20-30세의 대학생 70명(남 38명, 여 32명)을 대상으로 2D영상과 적록안경방식의 anaglyph 3D영상을 각각 30분 시청한 후 자각 증상을 설문 조사하였고, 2D영상과 3D영상 시청 전 후의 Titmus circles 및 TNO입체시를 평가하여 시각적 자각 증상과 입체시의 상관관계를 평가하였다. 결과: 2D영상과 3D영상 시청 후의 시각과 비시각적 자각 증상 모두 3D영상에서 높게 나타났다. 편광방식의 Titmus circles 입체시는 2D 및 3D영상 시청전과 후의 변화는 없는 것으로 나타났지만 적록안경방식의 TNO 입체시는 3D영상을 시청 후 더 좋은 것으로 나타났다. 3D영상 시청 후 시각적 자각 증상과 TNO 입체시는 증가하였고, 뚜렷한 상관관계(r=0.605)를 보였다. 결론: 시청 전의 입체시가 좋으면 3D영상 시청에서 상대적으로 시각적 자각 증상은 낮았다. 그러나 단시간 anaglyph 3D영상 시청에서 자각 증상이 증가되며, TNO 입체시의 향상은 시각적 자각 증상 완화와 관련성이 낮은 것으로 평가된다. 이러한 경향은 적록안경방식의 anaglyph 3D영상에 대한 적응 과정의 하나로 여겨진다.
