본 발명은 일반 브이씨알 카메라로 입체영상을 촬영할 수 있도록 한 아답타에 관한 것으로, 특히 넓은 각도의 카메라렌즈를 사용한 카메라에서도 시각이 유지될 수 있도록 한 입체촬영용 브이씨알 카메라의 아답타에 관한 것이다.The present invention relates to an adapter capable of capturing a stereoscopic image with a general VR camera, and more particularly, to an adapter of a stereo camera for a stereoscopic photographing camera capable of maintaining a vision even in a camera using a wide angle camera lens.

일반적으로 브이씨알 카메라의 광학계 원리는 제 1 도에 도시한 바와 같이, 카메라렌즈(1)를 통과한 비축상의 점으로부터의 광선이 이미지스캐너(2)를 통과한 후 신호처리부(3)를 통해 영상신호를 형성하였다.Generally, as shown in FIG. 1, the optical system principle of the VRC camera is an image obtained through the signal processing unit 3 after the light beam from the non-axis point passing through the camera lens 1 passes through the image scanner 2. A signal was formed.

그런데 여기에서는 한 위치에서 보는 영상만을 얻어내므로 입체촬영이 되지 않게 된다. 한편 일반적인 비데오 카메라렌즈로 줌렌즈를 채택하고 있는데, 이 렌즈가 넓은 (Wide) 각도로 동작할 경우에는 좀 더 큰 기울기를 갖는 평행광선까지도 이미지스캐너(2) 위에 결상되므로 입체촬영이 되지 못하게 되는 결함이 있었다.However, in this case, since only the image viewed from one position is obtained, stereoscopic imaging is not possible. On the other hand, the zoom lens is adopted as a general video camera lens. When the lens is operated at a wide angle, even a parallel beam having a larger slope is formed on the image scanner 2 so that stereoscopic imaging cannot be performed. there was.

본 발명은 이와 같은 종래의 결함을 감안하여, 일반 브이씨알 카메라로 입체촬영을 할 수 있게 할 뿐 아니라 넓은 각도의 렌즈를 사용한 카메라에서도 입체촬영을 가능하게 한 입체촬영용 브이씨알 카메라의 아답타를 창안한 것으로, 이를 첨부한 도면에 의하여 설명하면 다음과 같다.In view of such a conventional deficiency, the present invention not only enables stereoscopic imaging with a general V-Cal camera, but also creates an adapter for a stereoscopic V-Cal camera capable of stereoscopic imaging even with a camera using a wide-angle lens. This will be described with reference to the accompanying drawings.

The reference numerals 41 and 42 denote the interface between the polarization prisms 14 (4) and 24.

제 5 도는 본 발명 아답타를 브이씨알 카메라에 접속시킨 상태에 대한 설명도로서 이에 도시한 바와 같이, 카메라렌즈(1)를 통과한 광선이 이미지스캐너(2)를 통해 신호처리부(3)에 인가되어 영상신호를 추출하게 한 브이씨알 카메라에 있어서, 상기한 카메라렌즈(1)의 전단에 광학계(8)를 설치하고, 상기한 신호처리부(3)로 부터 추출된 수직동기신호가 콘트롤부(7)에 인가되어, 그 콘트롤부(7)에 의해 상기 좌, 우측 편광체판(23)(13)을 제어하게 구성한 것이다.5 is an explanatory diagram of a state in which an adapter of the present invention is connected to a VRC camera. As shown in FIG. 5, light beams passing through the camera lens 1 are applied to the signal processor 3 through the image scanner 2. In the VR camera which extracts the video signal, the optical system 8 is provided in front of the camera lens 1, and the vertical synchronization signal extracted from the signal processing unit 3 is controlled by the control unit 7. Is applied to the left and right polarizer plates 23 and 13 by the control unit 7.

이와 같이 구성된 본 발명의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above in detail.

일반적인 브이씨알 카메라에 제 5 도에 도시한 바와 같이 입체촬용용 아답타를 접속시키게 되면, 대물렌즈(11)(21)를 통과한 빛이 필드렌즈(12)(22)를 통해 모든 방향으로 입사되어 우, 좌측 편광체판(13)(23)에 전달되며, 이때, 우, 좌측 편광체판(13)(23)은 콘트롤부(7)로부터 저전위가 입력될때 빛을 차단하고, 고전위가 입력될때 TM, TE 편광빛을 통과시켜 각각의 편광프리즘(14)(24)에 전달한다.When the stereoscopic adapter is connected to a general VR camera as shown in FIG. 5, light passing through the objective lenses 11 and 21 is incident in all directions through the field lenses 12 and 22. The right and left polarizer plates 13 and 23 are transferred to the right polarizer plates 13 and 23. In this case, the right and left polarizer plates 13 and 23 block light when a low potential is input from the controller 7, and a high potential is input. TM and TE polarized light is passed through each polarizing prism (14, 24).

여기서, 그 편광프리즘(14)(24)에 전달되어 통과한 빛은 제 3 (a)도에 도시한 바와 같이, 편광프리즘(24)(5)(14)(4)를 통해 B→C→D→E의 경로로 반사되어 옮겨진다.Here, the light transmitted to and passed through the polarizing prisms 14 and 24 passes through the polarizing prisms 24, 5, 14 and 4 as shown in FIG. It is reflected and moved in the path of D → E.

그런데, 여기서 편광프리즘(14)(4)의 경계면(41)은 TM 편광은 투과하고, TE 편광은 반사하도록 코팅되어 있으며, 편광프리즘(24)(4)의 경계면(42)은 TM 편광을 반사하고, TE 편광은 투과하도록 코팅되어 있다.By the way, here the interface 41 of the polarization prism 14 (4) is coated so that TM polarization is transmitted, and TE polarization is reflected, and the interface 42 of the polarization prism 24 (4) reflects TM polarization TE polarized light is coated to transmit.

따라서, 편광프리즘(14)을 통과한 TM 편광광선은 경계면(41)의 존재와 무관하게 경계면(42)에 의해 반사된 후 편광프리즘(5)을 거쳐 아포칼라이즈레즈(6)로 입력되고, 편광프리즘(24)을 통과한 TE 편광광선은 경계면(42)의 존재와 무관하게 경계면(41), 편광프리즘(5)을 거쳐 아포칼라이즈렌즈(6)로 입력된다.Accordingly, TM polarized light passing through the polarization prism 14 is reflected by the interface 42 irrespective of the presence of the interface 41 and then input to the apocalase reds 6 through the polarization prism 5, The TE polarized light passing through the polarizing prism 24 is input to the apocalize lens 6 via the boundary 41 and the polarizing prism 5 regardless of the existence of the boundary 42.

이때, 아포칼라이즈렌즈(6)는 대물렌즈(11)(21)로, 입사되는 평행광을 다시 평행광으로 만들어줌으로써 뒷단에 있는 카메라렌즈(1)가 정상적으로 이미지스캐너(2) 위에 상을 맺을 수 있도록 해주며, 이의 광학계 기능을 간단하게 도시하면 제 6 도에 도시한 바와 같이 된다.At this time, the apocalypse lens 6 is the objective lens (11) (21), by making the incident parallel light back to parallel light so that the camera lens (1) at the rear end normally forms an image on the image scanner (2). A simple illustration of its optical system function is shown in FIG.

즉, 대물렌즈(11)(21)와 아포칼라이즈렌즈(6)의 두 촛점거리를 같게 함에 따라 입사되는 평행광선이 대물렌즈(11)(21)를 통해 내부 이미지로 결상되고, 내부 이미지는 다시 아포칼라이즈렌즈(6)를 통해 평행광선으로 변화되어 카메라렌즈(1)에 입사된다.That is, as the two focal lengths of the objective lenses 11 and 21 and the apocalypse lens 6 are the same, the incident parallel rays are formed into the internal image through the objective lenses 11 and 21, and the internal image is The light is converted into parallel light through the apocalase lens 6 and is incident on the camera lens 1.

여기서 광선(a)(b)는 대물렌즈(11)(21) 및 아포칼라이즈렌즈(6)를 거친 후 뒤집어지게 되는데, 이때 뒤집어짐은 편광프리즘(4)(5)(14)(24)에서의 뒤집어짐으로 인하여 보상된다.Here, the light beams (a) and (b) pass through the objective lenses 11 and 21 and the apocalase lens 6, and are then flipped over, where the flip is the polarization prism (4) (5) (14) (24). Compensated by flipping over at

즉,

It turns into a ray of direction.

한편 콘트롤부(7)는 우, 좌측 편광체판(13)(23)을 제어하여, 한필드씩 번갈아가며, 우, 좌측에서 본 영상이 얻어지도록 하는 것으로, 전하결합소자(CCD)와 같은 촬상소자의 경우 포토센서에서 발생한 광전자들은 수직동기신호가 인가될때 동시에 전송되므로 우, 좌측으로 입사하는 빛이 수직동기신호의 앞단에서 스위칭된다.On the other hand, the control unit 7 controls the right and left polarizer plates 13 and 23 so as to alternate between fields one by one, and to obtain images viewed from the right and left sides of the imaging device such as a charge coupled device (CCD). In this case, since the photoelectrons generated in the photosensor are transmitted simultaneously when the vertical synchronous signal is applied, the light incident to the right side is switched at the front end of the vertical synchronous signal.

따라서 신호처리부(3)로부터 추출된 수직동기신호가 미분회로(71)를 통해 미분되고, 다이오드(72)와 파형정형부(73)를 통해 펄스로 변화된 후 플립플롭(74)에 클럭신호로 공급된다.Accordingly, the vertical synchronization signal extracted from the signal processing unit 3 is differentiated through the differential circuit 71, is converted into a pulse through the diode 72 and the waveform shaping unit 73, and then supplied to the flip-flop 74 as a clock signal. do.

이때 플립플롭(74)의 출력단자(Q)(

Figure kpo00004
) 신호가 각각의 편광체판 드라이버(76)(75)를 통해 우, 좌측 편광체판(13)(23)의 온/오프기능을 제어함으로써 좌, 우측에서 본 입체영상이 얻어지는 것이다.At this time, the output terminal Q of the flip-flop 74 (
Figure kpo00004
) Is obtained by controlling the on / off function of the right and left polarizer plates 13 and 23 through the respective polarizer plate drivers 76 and 75.

여기서 대물렌즈(11)(12)와 아포칼라이즈렌즈(6)는 넓은 각도의 촬영시에도 빛이 흩어지지 않도록 하는 역할을 한다.Here, the objective lenses 11 and 12 and the apocalypse lens 6 serve to prevent light from being scattered even when shooting at a wide angle.

이상에서 상세히 설명한 바와 같이 본 발명은 좌, 우측 편광체판의 스위칭작용으, 로 입체영상신호를 얻도록 한 아답타를 형성함에 따라 일반 브이씨알 카메라로 입체영상을 촬영할 수 있을뿐 아니라 넓은 각도의 카메라렌즈를 사용한 카메라에서도 입체촬영이 가능하게 되는 효과가 있다.As described in detail above, the present invention forms an adapter for obtaining a stereoscopic image signal by switching the left and right polarizer plates, so that the stereoscopic image can be photographed with a general VR camera as well as a wide angle camera lens. In the camera using the three-dimensional shooting effect is possible.
