본 발명은 필름식 광학필터 장치에 관한것으로서, 더욱 상세하게는 카메라나 캠코더의 렌즈부에 필름식으로 된 광학필터를 설치하여 사용자가 다양한 광학필터를 선택하여 효과적으로 사용할 수 있도록 한 것이다.The present invention relates to a film type optical filter device, and more particularly, a film type optical filter is installed in a lens portion of a camera or a camcorder so that a user can effectively select and use various optical filters.
종래 카메라에서 사용되는 광학필터는 제1도에 나타낸 바와같이, 카메라의 렌즈부(1)에 필터홀더(2a)를 고정시키고, 필터홀더(2a)에 카드형태로 된 광학필터(4a)를 삽입하여 사용했으며. 캠코더에 회로적인 수퍼 임포우즈(Super Impose) 기능은 있으나 광학적인 필터가 사용되지 않았다.In the optical filter used in the conventional camera, as shown in FIG. 1, the filter holder 2a is fixed to the lens portion 1 of the camera, and the optical filter 4a in the form of a card is inserted into the filter holder 2a. I used it. The camcorder has a circuital super impose function, but no optical filter.
그러므로, 사용자가 카메라에서 카드형태의 광학필터(4a)를 사용할때에는 매번 카드형의 광학필터(4a)를 바꿔끼워야 하므로 인한 불편함이 있을 뿐만 아니라, 캠코더에 수퍼임포우즈 기능을 구형하기 위해 광학적 인 필터가 아닌 회로적인 방식으로 설치하여 사용하므로 제작단가가 상승하게 되는 등이 문제점이 있었다.Therefore, when the user uses the card-type optical filter 4a in the camera, the card-type optical filter 4a must be replaced every time, and not only is it inconvenient, but also the optical for the superimpose function of the camcorder. There is a problem that the manufacturing cost increases because it is installed and used in a circuit manner rather than a filter.
본 발명은 상기한 제반 문제점을 해결하기 위한것으로서, 본 발명은 카메라나 캠코더의 렌즈부에 필름식으로 된, 광학필터를 설치하므로써, 사용자가 다양한 광학필터를 선택해서 효과적으로 사용할 수 있어서 카메라나 캠코더의 효율성 및 신뢰성을 향상시킬 수 있는 필름식 광학필터 장치를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. The present invention provides a film-type optical filter in the lens portion of a camera or camcorder, whereby the user can effectively select and use various optical filters, so that It is an object of the present invention to provide a film type optical filter device that can improve efficiency and reliability.
상기한 목적을 달성하기 위해 본 발명은 렌즈부에 고정되는 필터홀더와, 상기 필터 홀더에 설치되어 회전하는 릴과, 상기 릴에 감겨진 필름형의 광학필터로 구성된 필름식 광학필터 장치이다.In order to achieve the above object, the present invention is a film-type optical filter device consisting of a filter holder fixed to the lens unit, a reel installed on the filter holder to rotate, and a film-type optical filter wound on the reel.
이하, 본 발명의 일실시예를 첨부된 도면 제2도 내지 제5도를 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 2 to 5.
제2도는 본 발명의 설치상태를 나타낸 종단면도이고, 제3도는 본 발명의 정면도이며, 제4도는 본 발명에 따른 필름식 광학필터의 정면도이고, 제5도는 본 발명이 캠코더에 설치된 상태를 나타낸 종단면도로서, 카메라나 캠코더의 렌즈부(1) 선단에 필터홀더(2)가 고정되고, 필터홀더(2)내의 상, 하부에는 각각 필름 형태로된 광학필터(3)를 감기 위한 릴(4)이 설치되며, 릴(4)의 일측에는 상기 광학필터(3)를 회전시켜 원하는 장면을 선택하기 위한 손잡이(5)가 상기 필터홀더(2)의 외부로 돌출되어 구성된다.2 is a longitudinal sectional view showing an installation state of the present invention, FIG. 3 is a front view of the present invention, FIG. 4 is a front view of a film optical filter according to the present invention, and FIG. 5 is a view showing a state where the present invention is installed in a camcorder. As a longitudinal sectional view, the filter holder 2 is fixed to the tip of the lens unit 1 of the camera or camcorder, and the reel 4 for winding the optical filter 3 in the form of a film on the upper and lower portions of the filter holder 2 respectively. ) Is installed, and one side of the reel (4) is configured to protrude to the outside of the filter holder (2) for rotating the optical filter (3) to select a desired scene.
이와같이 구성된 본 발명은 제2도 내지 제5도에 나타낸 바와같이, 카메라의 렌즈부(1) 선단에 필터홀더(2)를 고정시킨 후, 필터홀더(2)내의 상, 하부에 설치된 릴(4)에 필름 형태로된 광학필터 (3)가 감겨있는 상태에서 상기 릴(4) 일측의 상기 필터홀더(2)의 외부로 돌출되어 형성된 손잡이 (5)를 돌리면, 상기 필름 형태로 된 광학필터(3)가 한쪽릴(4)에서 다른쪽릴(4)로 감기게 된다.According to the present invention configured as described above with reference to FIGS. 2 to 5, the filter holder 2 is fixed to the tip of the lens unit 1 of the camera, and then the reels 4 provided on the upper and lower portions of the filter holder 2 are mounted. In the state in which the optical filter 3 in the form of a film is wound, the knob 5 formed to protrude out of the filter holder 2 on one side of the reel 4 is turned, and the optical filter in the form of film 3) is wound from one reel (4) to the other reel (4).
따라서, 사용자는 필름 형태로된 광학필터(3)를 손잡이(5)로 돌리면서 원하는 장면에 상기 광학필터(3)를 고정시켜서 촬영하게 된다.Accordingly, the user is photographed by fixing the optical filter 3 to a desired scene while rotating the optical filter 3 in the form of a film with the knob 5.
또한, 본 발명을 캠코더에 장착한 후, 포커스 스위치를 수동의 위치에 놓고 촬영하므로써 현재 회로적으로 구현하고 있는 수퍼임포우즈 기능을 필름식의 광학필터(3)로 대체할 수 있어서 제작단가를 절감시킬 수 있을 뿐만 아니라, 수퍼임포우즈 기능이 없는 캠코더에서는 수퍼임포우즈 기능과 유사한 효과를 얻을 수 있게 된다.In addition, after the present invention is mounted on a camcorder, the focus switch can be set to a manual position and the film can be replaced by a film-type optical filter 3 to superimpose the current circuit. In addition to this, camcorders without the superimpose function will have an effect similar to that of the superimpose function.
이상에서와 같이 본 발명은 카메라나 캠코더의 렌즈부(1) 선단에 고정되는 필터홀더(2)내에 필름 형태로 된 광학필터(3)를 릴(4)에 감아 릴(4)과 일체로 형성되어 필름홀더(2)의 외부로 돌출된 손잡이(5)를 회전시켜 사용자가 원하는 장면을 선택하여 사용할 수 있으므로써, 사용자에게 편리함 및 만족감을 제공하여 카메라나 캠코더의 효율성 및 신뢰성을 대폭향상시킴 매우 유용한 발명이다.As described above, in the present invention, the optical filter 3 in the form of a film is wound around the reel 4 and integrally formed with the reel 4 in the filter holder 2 fixed to the tip of the lens 1 of the camera or camcorder. The user can select and use the desired scene by rotating the handle 5 protruding from the outside of the film holder 2, which greatly improves the efficiency and reliability of the camera or camcorder by providing convenience and satisfaction to the user. It is a useful invention.
