Description

마이크로프리즘 어레이를 이용한 스테레오스코픽 이미징 장치Stereoscopic Imaging Device Using Microprism Array
본 발명은 3차원 입체 영상 투영 장치에 관한 것으로, 보다 상세하게는 3차원 입체영상을 관측하는 편광 액정판 안경을 착용하지 않고도 3차원의 입체영상을 얻을수 있도록 한 스테레오스코픽 이미징 장치에 관한 것이다.The present invention relates to a three-dimensional stereoscopic image projection apparatus, and more particularly to a stereoscopic imaging apparatus to obtain a three-dimensional stereoscopic image without wearing a polarizing liquid crystal plate glasses for observing the three-dimensional stereoscopic image.
최근 3D 입체 영화의 성공, 3D TV의 대중화와 함께 본격적인 3D 콘텐츠 서비스 시대가 열리게 될 것이라는 기대가 커지고 있다. 영화와 방송 산업의 3D 진입 가속화는 3D 디스플레이 기술, 3D 콘텐츠 제작, 3D 전송 인프라 등 3D 콘텐츠 산업 활성화와 함께 3D 입체 영상 관련 제반 기술 발전의 토대가 되고 있다. 또한 3D 디스플레이 기술의 발전과 대중의 3D 콘텐츠에 대한 관심의 증가는 3D 방송, 영화, 게임 등과 같이 다양한 경로로 사용자들에게 3D 콘텐츠를 보급할 수 있는 여건을 마련하는 초석이 되고 있다.Recently, with the success of 3D stereoscopic movies and the popularization of 3D TVs, there is growing expectation that the era of full-scale 3D contents service will be opened. The acceleration of 3D entry into the film and broadcasting industry is laying the foundation for the development of 3D stereoscopic technology along with the activation of the 3D contents industry such as 3D display technology, 3D contents production, and 3D transmission infrastructure. In addition, the development of 3D display technology and the increasing interest in 3D content by the public has become a cornerstone for preparing the conditions for distributing 3D content to users through various channels such as 3D broadcasting, movies, and games.
하지만, 이와 같은 본격적인 3D 영상 시대에 대한 기대감에도 불구하고 3D 영상 콘텐츠의 부족과 시청 안전성 이슈는 향후 3D 시장 성장을 저해하는 요인으로 작용할 것이라는 우려도 또한 커지고 있다. 예를 들어, 인체의 입체 영상 인식 구조를 이용하여 양안의 시차를 입체 영상 구현에 활용하는 스테레오스코픽 방식의 경우, 3D 입체 영상의 구현을 위하여 많이 사용되는 방식임에도 불구하고 시청 안전성에 대한 이슈가 끊임없이 제기 되고 있기도 하다. 스테레오스코픽 방식의 3D 입체 영상의 경우 특히 시각적 불편감(visual discomfort)과 시각피로(visual fatigue) 등의 증상이 발생할 수 있는 것으로 알려져 있다.However, despite such expectations for the full-fledged 3D video era, there is also a growing concern that the lack of 3D video content and viewing safety issues will hinder future 3D market growth. For example, the stereoscopic method that uses the parallax of both eyes to implement stereoscopic image using the stereoscopic image recognition structure of the human body, despite the many methods used to implement 3D stereoscopic image, the issue of viewing safety is constantly It is being raised. In the case of stereoscopic 3D stereoscopic images, symptoms such as visual discomfort and visual fatigue are known to occur.
또한, 현재 3D 콘텐츠 제작 워크플로우에서는 기술적 지원의 부족으로 인해 많은 시간과 비용이 소요되는 것으로 알려져 있다. 이러한 높은 비용은 주로 시각적 불편감 없는 영상 제작을 위해 촬영 시에 들어가는 고비용의 수작업 모니터링과 재편집 및 재촬영의 과정에 기인한다. 이러한 높은 제작 비용으로 인한 3D 콘텐츠의 부족은 3D영상 산업의 활성화에 걸림돌이 되고 있다. 따라서 적은 비용으로 보다 쉽게 시각적 불편감 없는 3D 콘텐츠의 제작을 가능하게 하는 방법 및 시스템이 필요하며, 이는 3D 콘텐츠 및 제반 시장을 본격적으로 활성화하는데 크게 기여할 수 있을 것이다.In addition, current 3D content creation workflows are known to be time consuming and costly due to the lack of technical support. This high cost is mainly due to the high cost of manual monitoring, re-editing and re-shooting, which takes place during filming to produce visually uncomfortable images. The lack of 3D content due to such high production costs has been an obstacle to revitalization of the 3D video industry. Therefore, there is a need for a method and system that enables the production of 3D content without visual discomfort more easily at a lower cost, which will greatly contribute to full-fledged activation of 3D content and the overall market.
