| 집적영상 기술의 두 가지 방식은? | 집적영상 기술은 렌즈 어레이와 디스플레이 장치 사이의 거리(g)에 따라서 크게 두 가지 종류의 방식으로 구분할 수 있다. 첫 번째 방식은 거리 g가 렌즈 어레이의 기초렌즈의 초점거리 (f)와 동일한 경우이고 두 번째 방식은 g가 f와 다른 경우로 나눌 수 있다. | |
| 양안시차방식에 기반한 3차원 디스플레이 기술의 단점은? | 현재 사용하고 있는 양안시차(stereo disparity)방식에 기반한 3차원(three-dimensional: 3D) 디스플레이 기술은 Real 3D를 보여주기에는 여러가지 기술적 한계가 있고, 결과적으로 실제 사용할 경우 눈의 피로 및 어지러움을 동반하고 있다. 따라서 실질적인 Real 3D 영상의 구현을 위해서는 인간의 시각과 거의 흡사한 구조와 원리를 적용한 새로운 형태의 Real 3D 영상 센싱, 이미징, 디스플레이 알고리즘 및 시스템의 연구개발이 요구된다. | |
| 양안시차 기반 스테레오 3D 디스플레이 방식에서 수직 깊이 경사 현상은 왜 발생하는가? | - 이는 일상생활에서 먼 물건은 위쪽에 가까운 물건은 아래쪽으로 보이는 경험적 요인으로부터 생긴다고 생각되어 양안시차가 제대로 재현되지 않아 발생. |
