Description

카메라 및 그를 구비한 입체 이미지 시스템Camera and stereoscopic imaging system with it
본 발명은 카메라 및 그를 구비한 입체 이미지 시스템에 관한 것이다.The present invention relates to a camera and a stereoscopic image system having the same.
일반적으로, 입체영상 카메라는 양안식과 단안식이 있으며, 양안식 카메라의 경우 주시각 제어방식 등에 따라 수평식, 폭주식 등이 있다. In general, a stereoscopic camera has a binocular type and a monocular type, and a binocular camera has a horizontal type or a congestion type according to a vergence control method.
수평식은 두 대의 카메라를 서로 평행하게 지그에 나란히 장착하고 두 카메라의 간격을 조절하는 방식이다. In the horizontal method, two cameras are mounted side by side on a jig parallel to each other and the distance between the two cameras is adjusted.
이 방식은 두 카메라 사이의 간격을 카메라의 크기보다 작게 조정할 수 없기 때문에 근접촬영시 양안 영상의 시차가 너무 크게 되어 시청자의 눈에 피로감을 준다. In this method, the distance between the two cameras cannot be adjusted smaller than the size of the camera, so the parallax of the binocular image becomes too large during close-up photography, which makes the eyes of the viewer tired.
또한, 주시각에 따라 촬영 범위를 달리하는 것이 곤란하다. In addition, it is difficult to vary the shooting range depending on the viewing angle.
폭주식의 경우 카메라의 간격은 고정하고 각각의 카메라를 회전시켜 주시각을 조절하는 방식이다. In the case of congestion, the distance between the cameras is fixed and each camera is rotated to adjust the viewing angle.
이 경우 주시각에 따른 조절은 가능하지만, 역시 피사체와의 거리가 가까우면 주시각이 커지면서 영상의 기하학적 왜곡이 심해진다. In this case, adjustment according to the viewing angle is possible, but if the distance to the subject is also close, the viewing angle becomes larger and the geometric distortion of the image becomes worse.
그외 수평축 이동방식의 경우 렌즈계에 대해 영상소자의 상대적인 위치를 조절하여 주시각을 조절한다. 이 방식의 경우 주시각의 조절이 용이한 반면 기구적인 구성이 복잡하여 제작 및 운용에 어려움이 있다. In addition, the horizontal axis shifting method adjusts the viewing angle by adjusting the relative position of the image device relative to the lens system. In this method, it is easy to adjust the visual angle, but the mechanical configuration is complicated, which makes it difficult to manufacture and operate.
최근, 입체 이미지에 대한 관심과 시장성이 폭발적으로 증가되고 있고, 이에 대한 다양한 연구가 진행되어 보다 향상된 입체 이미지를 획득하려는 시도가 이루어지고 있다.Recently, the interest and marketability of stereoscopic images have explosively increased, and various studies have been conducted to attempt to acquire more improved stereoscopic images.

이때, 상기 이미지 신호 프로세서(200)는 푸리에 변환 소프트웨어, 프로젝션 알고리즘 소프트웨어 등을 이용하여 다수의 이미지(20)를 개별 광 이미지로 분리한다.In this case, the image signal processor 200 separates the plurality of images 20 into individual optical images using Fourier transform software, projection algorithm software, and the like.
그리고, 도 4를 참조하면, 상기 이미지 신호 프로세서(200)는 개별로 분리된 이미지들(21,22,23,24,25,26,27,28,29)를 출력하게 된다.4, the image signal processor 200 outputs separately separated images 21, 22, 23, 24, 25, 26, 27, 28, and 29.
도 5는 본 발명에 따른 카메라에서 획득된 다수의 이미지로 입체감 있는 광 이미지를 표시하는 방법을 설명하기 위한 개념적인 도면이고, 도 6a 내지 도 6c는 도 5의 방법에 의해 획득된 이미지에서 피사체가 움직이는 효과를 설명하기 위한 도면이다.FIG. 5 is a conceptual view illustrating a method of displaying a stereoscopic optical image with a plurality of images acquired by a camera according to the present invention. FIGS. 6A to 6C are diagrams illustrating a subject in an image obtained by the method of FIG. 5. It is a figure for demonstrating a moving effect.
카메라에서 획득된 다수의 이미지들(21,22,23,24,25,26,27,28,29)은 포커싱된 이미지에서 피사체의 원근(遠近)에 의해 순서를 정하고, 표시부의 화면에 주사하게 되면, 도 5의 '30'과 같이 입체감 있는 이미지를 구현할 수 있게 된다.A plurality of images (21, 22, 23, 24, 25, 26, 27, 28, 29) acquired by the camera are ordered by the perspective of the subject in the focused image and scanned on the screen of the display unit. In this case, it is possible to implement a three-dimensional image as shown in '30' of FIG.
여기서, 피사체의 원근에 의해 의해 순서를 정하는 것은 획득된 이미지들 중, 가까운 곳 포커싱 이미지에서 먼곳 포커싱 이미지로, 또는 먼곳 포커싱 이미지에서 가까운 곳 포커싱 이미지로 순서를 정하는 것을 의미한다.Here, ordering by the perspective of the subject means ordering from the near focusing image to the far focusing image or the far focusing image from the near focusing image.
즉, 도 5와 같이, 이미지 '25'에서 '26','21','22','23','24','29','28',27'의 순서로 표시부에 주사(화살표 방향으로)하게 되면, 볼륨이 있는 이미지 '30'이 표시부에 표시되는 것이다.That is, as shown in FIG. 5, the image is scanned on the display unit in the order of '26', '21', '22', '23', '24', '29', '28', and 27 '(arrows). Direction, the image with volume '30' is displayed on the display.
이때, 상기 표시부는 이미지의 순서대로, 1초에 30프레임 이상 이미지를 주사하게 된다.In this case, the display unit scans an image of 30 frames or more per second in the order of the images.
이와 같이, 획득된 이미지들을 표시부에서 주사하게 되면, 예를 들어 도 6a 내지 도 6c와 같이, 주사된 이미지들 '25','26','21'에서 피사체의 위치가 다르게 되여, 피사체가 미세하게 움직이는 효과가 발생하고, 이 움직이는 효과는 운동 시차를 발생시켜 입체감을 느끼게 된다.As such, when the acquired images are scanned on the display unit, for example, as shown in FIGS. 6A to 6C, the positions of the subjects are different from the scanned images 25, 26, and 21, so that the subject is fine. The moving effect is generated, and this moving effect generates a motion parallax to feel a three-dimensional feeling.
한편, 본 발명은 이미지의 순서를 정하는 방식이 피사체의 원근에 의한 것으로 한정되는 것이 아니라 다양한 방식이 적용될 수 있다.On the other hand, the present invention is not limited to the method of ordering the image by the perspective of the subject can be applied in various ways.
따라서, 본 발명은 하나의 카메라로 촬영된 피사체의 이미지에 입체감을 부여할 수 있게 된다.Therefore, the present invention can impart a three-dimensional effect to an image of a subject photographed by one camera.
도 7은 본 발명에 따른 카메라를 구비한 입체 이미지 시스템(3-Dimensional image system)의 구성을 설명하기 위한 개략적인 도면이다.FIG. 7 is a schematic view for explaining the configuration of a three-dimensional image system having a camera according to the present invention.
전술된 카메라는 하나이지만, 본 발명의 입체 이미지 시스템은 2개의 카메라 각각에, 피사체의 광 이미지를 다중 경로로 출사시키는 광학 소자를 구비할 수 있다.Although there is only one camera described above, the stereoscopic image system of the present invention may include, in each of the two cameras, an optical element that emits an optical image of a subject in multiple paths.
이경우, 도 7과 같이, 표시부(300)에 3차원 이미지(35)를 표시할 수 있으며, 3차원 안경(500)을 착용한 사용자는 상기 3차원 이미지(35)를 시각할 때, 좌, 우 눈에 표시되는 화면이 양안시차와 더불어 운동시차에 의해 3차원 입체 이미지를 시각할 수 있어, 이미지의 깊이 및 두께를 느끼게 됨으로써, 입체감은 증가될 수 있는 것이다.In this case, as shown in FIG. 7, the 3D image 35 may be displayed on the display unit 300. When the user wearing the 3D glasses 500 views the 3D image 35, left and right sides thereof are displayed. The screen displayed on the eye can visualize the 3D stereoscopic image by the motion parallax together with the binocular parallax, so that the depth and thickness of the image can be felt, thereby increasing the stereoscopic feeling.
그리고, 본 발명의 입체 이미지 시스템은 다수의 카메라 각각에 피사체의 광 이미지를 다중 경로로 출사시키는 광학 소자를 구비할 수도 있다.In addition, the stereoscopic image system of the present invention may include an optical element that emits an optical image of a subject in multiple paths in each of the plurality of cameras.
이러한 카메라는 움직이는 피사체를 고속 촬영하는 용도로 활용될 수 있다.Such a camera may be used for high speed photography of a moving subject.
상술된 바와 같이, 본 발명은 좌우 양안시차로만 표현하는 경우 발생하는 부족한 볼륨감을 강화시킬 수 있고, 하나의 카메라에서 촬상된 이미지도 입체감을 부여할 수 있는 장점이 있는 것이다.As described above, the present invention can enhance the lack of volume generated when expressed only by left and right binocular disparity, and the image captured by one camera can also give a three-dimensional effect.
이상에서 본 발명에 따른 실시예들이 설명되었으나, 이는 예시적인 것에 불과하고, 당해 분야에서 통상적 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 범위의 실시예가 가능하다는 점을 이해할 것이다. 따라서, 본 발명의 진정한 기술적 보호 범위는 다음의 특허청구범위에 의해서 정해져야 할 것이다.Although embodiments according to the present invention have been described above, these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent embodiments of the present invention are possible therefrom. Therefore, the true technical protection scope of the present invention will be defined by the following claims.
본 발명은 다중 경로로 출사된 광 이미지를 촬상할 수 있어, 표시되는 피사체의 이미지의 입체감을 증가시킬 수 있는 카메라 및 시스템을 제공할 수 있다.The present invention can provide a camera and a system capable of capturing an optical image emitted in a multi-path, thereby increasing the three-dimensional effect of the image of the subject to be displayed.
