Abstract

본 발명은 입체영상 표시장치에 관한 것으로, 종래 입체영상장치는 오른쪽 카메라와 왼쪽 카메라를 이용하여 투명부와 불투명부가 교대로 배열되는 자중슬리트격자로 이용하고, 두 대의 투영기를 이용함으로써 휴대가 불가능한 단점이 있었다. 본 발명은 이러한 단점을 해결하기 위하여 하나의 투영기와 디지탈처리장치만으로 오른쪽과 왼쪽으로 분리된 각 입체영상정보를 디지탈적으로 처리하여 등 주기로 이웃하게 교대로 합성시켜 각 입체 영상정보를 광각이 다르게디스플레이시켜 입체영상을 감상할 수 있도록 하는 입체영상 표시장치를 제공하는 것이다.The present invention relates to a three-dimensional image display device, a conventional three-dimensional image device is used as a self-weighted slit lattice in which the transparent portion and the opaque portion are alternately arranged using a right camera and a left camera, it is impossible to carry by using two projectors There was a downside. In order to solve this problem, the present invention digitally processes each stereoscopic image information divided into right and left by using only one projector and a digital processing device, and alternately synthesizes the stereoscopic image information at regular intervals so that each stereoscopic image information is displayed at a wide angle. It is to provide a three-dimensional image display device that allows to enjoy a three-dimensional image.
