Abstract

본 발명은 안경을 사용하지 않는 편광입체영상재현 시스템에 관한 것이다.The present invention relates to a polarized stereoscopic image reproduction system that does not use glasses.

오른쪽 영상을 찍은 필름을 영사하는 오른쪽 영사기에는 종편광필터를 영사기 앞에 설치하며, 왼쪽 영상을 찍은 필름을 영사하는 왼쪽 영사기에는 횡편광필터를 영사기 앞에 설치하여 편광필터가 설치 되어진 입체영상재현 스크린에 투영하는 기술이다.On the right projector that projects the film on the right image, a longitudinal polarization filter is installed in front of the projector. On the left projector that projects the film on the left image, a transverse polarization filter is installed in front of the projector to project onto a stereoscopic image reproduction screen equipped with a polarization filter. It is a technique to do.

이때의 입체영상재현스크린은 편광필터를 포함하는 결상면과 렌티규라 스크린으로 구성되어진다.In this case, the stereoscopic image reproduction screen is composed of an imaging surface including a polarization filter and a lenticular screen.

종편광필터와 횡편광필터가 등간격으로 교대로 반복되게 결상면에 구성이 되어져 있으면. 하나의 랜티큐라렌즈의 폭안에 종편광필터와 횡편광필터가 한 쌍을 이루어서 위치되어져 있다.If the vertical polarizing filter and the horizontal polarizing filter are configured on the imaging surface in such a manner that they are alternately repeated at equal intervals. A pair of longitudinally polarized light filters and transversely polarized light filters are located in the width of one lenticular lens.

즉 렌티큐라 스크린의 결상면에는 횡,종,횡,종,횡‥‥으로 복합편광필터가 설치되어 있어서 각각에 편광필터를 설치한 두대의 영상기를 통하여 좌,우의 영상을 투영하게 되면 렌티큐라 스크린의 결상면에는 좌,우,좌,우,좌,우의 영상정보가 교대로 반복되어 입체영상정보가 형성이 되어지며 렌티큐라렌즈를 통하여 이들은 입체영상을 나타내게 되는 것이다.In other words, the image of the lenticular screen is provided with a horizontally, vertically, horizontally, vertically and horizontally. The image information of the left, right, left, right, left, and right is alternately repeated on the imaging surface of to form three-dimensional image information.

따라서 이렇게 구성이 되어진 입체영상재현 시스템은 편광을 사용하기는 하나 종래기술과는 달리 안경을 착용하지 않고 입체 영상을 관람할수 있는 장점을 지니게 된다.Therefore, the three-dimensional image reproduction system configured as described above has the advantage of viewing the three-dimensional image without wearing glasses, unlike the prior art, but using polarized light.
