Abstract

본 발명은 광학계의 촬영렌즈에 관한 것으로, 일측면이 원통형으로 구성된 실린드리컬 렌즈(Cylindrical Lens)를 이용하여 그 각각의 촛점거리를 다르게 하므로써 좌우 상하 배율을 변화 가능하도록 하고 피사체의 영상이 맺히는 상점의 위치 즉, 결상되는 위치만 같아지도록 광학시스템(예컨데, 물상의 물점/제1렌즈/제1실린드리컬 렌즈/제2실린드리컬 렌즈/제2렌즈/상점이 3차원 공간 좌표 상의 일직선 상에 배치된 형태)을 형성하므로써 피사체의 가로 및 세로 비율을 서로 다르게 결상시킬 수 있게 되어 뚱뚱한 사람을 날씬하게 하거나 혹은 야윈 사람을 통통하게 촬영하는 것이 가능하게 되어 필름을 사용하는 카메라 뿐 아니라 CCD카메라 등 모든 광응용기기에 활용이 가능한 고신뢰성이 촬영렌즈를 이용한 광학시스템을 실현할 수 있게 된다.The present invention relates to a photographing lens of the optical system, by using a cylindrical lens (Cylindrical Lens) consisting of one side of the cylinder by varying the respective focal lengths to be able to change the left and right vertical magnification and store the image of the subject The optical system (e.g., water point / first lens / first cylindrical lens / second cylindrical lens / second lens / spot) on a three-dimensional spatial coordinate Formed in the shape of the shape), it is possible to image the aspect ratio of the subject differently, so that it is possible to thin a fat person or to shoot a lean person plumply, and not only a camera using a film but also a CCD camera, etc. High reliability, which can be used in all optical applications, enables optical systems using photographing lenses.
