초점 흐림 현상을 이용해 영상을 분할하거나 깊이를 추정하는 것은 성능이 떨어진다는 평가를 받아왔다. 그런데 최근에 다수의 카메라를 하나의 거대한 카메라로 해석하는 합성 조리개 시스템으로 새롭게 주목을 받고 있다. 이를 통해, 초점 면과 심도를 조절할 수 있는 합성 사진을 만들어 낼 수 있었지만, 이때 카메라의 간격에 따른 왜곡현상이 결과의 질을 저하시켰으며, 또 한편으로 흐림을 판단하는 척도로서의 분산 값은 배경과 조명 상황에 따라 오차의 폭이 큰 문제가 있었다. 따라서 본 논문은 EPI 공간에서 합성 픽셀을 보간하여 향상된 합성 사진을 얻는 방법을 소개하였고, 또 변화율 기반의 분산 측정을 제안하여 배경과 조명 영향에 보다 강인하게 전/배경을 분리한다. 또 카메라 폭과 합성 조리개의 초점 심도, 그리고 사물의 위치관계를 분석하여 본 연구의 적용범위를 제한하였다.
