입체 영상의 왼쪽과 오른쪽이 서로 바뀐 ‘pseudo-stereoscopic' 영상에서는 올바른 입체감을 느끼기 어려운데, 이를 해결하기 위해서는 직접 눈으로 보고 ’pseudo-stereoscopic' 영상 여부를 판단하여 두 영상을 바꿔줘야 하는 불편함이 있었다. 따라서 본 논문에서는 입체 영상 사이에 갖고 있는 특성을 이용하여, pseudo-stereoscopic 영상을 자동으로 확인하고, 이를 바꿔주는 방법을 제시하고자 한다. 이를 위해 입체 영상으로부터 카메라의 종류를 확인하여, 교차축 카메라의 경우는 교정화 과정을 수행한다. 그리고 한 쪽 영상에서 선택한 비교 영역과 다른 쪽 영상의 대응 영역 사이의 변이 값을 비교함으로써 pseudo-stereoscopic 영상을 판단하고, 올바르게 바꿔줌으로써 시청자가 올바른 입체감을 느낄 수 있도록 하였다.
