이때, 본 발명에서는 카메라모듈(20)이 단말기 본체(10)의 후면에 내장된 것을 도시하였지만, 이에 한정되는 것은 아니며 단말기 본체(10)의 전면이나 일 측면 등 다양한 위치에 설치되는 것이 가능함은 물론이다. At this time, in the present invention, the camera module 20, the terminals been shown that the built-in to the back of the main body 10, and thus limited not intended to be installed in various positions such as the front and one side of the terminal body 10 are possible, as well to be.

또한, 카메라모듈(20)의 주변에는 적외선 촬영이 가능하도록 적외선 LED가 설치된다. In addition, the infrared LED is provided near the camera module 20 is provided to enable the infrared photographing.

한편, 카메라모듈(20)의 선단에는 일정부분이 함몰되는 홈 형태의 삽입부(11)가 형성되고, 삽입부(11)의 일측 내부에는 상기 삽입부(11)에 설치되는 필터부재(40)의 슬라이딩운동이 가능하도록 삽입홈(12)이 구비된다. On the other hand, the front end of the camera module 20 is formed with the insertion portion 11 of the groove form which is a portion recessed, inner side of the insertion portion 11, the filter member 40 disposed in the insertion portion 11 the insert is provided with a groove 12 to enable the sliding movement.

필터부재(40)는 단말기 본체(10)에 구비된 삽입부(11)에 결합 가능한 형태로 구성되는 판체형으로 중심을 기준으로 일측에는 적외선 영역의 파장을 제거하는 IR 코팅부(41)가 형성되고, 다른 일측에는 적외선 영역의 파장을 모아주는 AR코팅부(42)가 형성된다. Filter member 40 is formed with a terminal body 10, the insertion portion IR coating unit 41 side by 11 around the center of a plate body composed of a combinable type to have to remove the wavelength of the infrared region having the and the other one is formed with the AR coating 42 is to gather the wavelengths of the infrared region.

한편, 삽입부(11)의 주변 단말기 본체에는 삽입부(11)와 연통되는 구조로 소정의 조작홈(13)이 구비되고, 필터부재(40)에는 상기 조작홈(13)을 통해 외부로 노출되는 조작레버(43)가 구비되어 필터부재(40)의 슬라이드 이동을 원활하고 용이하게 구현할 수 있다. On the other hand, the peripheral terminal unit, the predetermined operation groove 13 to the structure to be in communication with the insertion portion 11 of the insertion portion 11 is provided, the filter member 40 is exposed to the outside through the operation groove 13 the operating lever 43, which is provided can be implemented smoothly and facilitates the sliding movement of the filter member 40.

도 2는 본 발명에 따른 무선 단말기에 설치되는 필터부재의 작동상태를 나타낸 작동상태도이다. 2 is an operational state diagram showing the operational state of the filter member is installed in the wireless terminal according to the present invention.

본 발명에 따른 무선 단말기(A)에 구비된 카메라모듈(20)을 이용한 촬영모드는 주간모드와, 야간모드로 구분된다. Recording mode using the camera module 20 with the radio terminal (A) according to the invention is divided into a day mode and a night mode.

먼저, 주간모드는 도 2a의 도시와 같이 비교적 광량이 많은 시간대에 사용되는 것이다. First, the day mode is used for a lot of time a relatively light amount as shown in Figure 2a. 이 경우에는 사람들이 눈으로 볼 수 없는 가시광선 영역(400~700nm)뿐 아니라, 근적외선 영역(~1150nm)까지도 카메라모듈(20)의 내부에 설치된 이미지센서가 감지하여 신호가 이미지센서를 포화시켜버리기 때문에 필터부재(40)의 IR필터부(41)가 카메라모듈(20)에 위치되도록 하여 적외선 영역의 파장을 제거하여 선명하고 깨끗한 이미지를 얻을 수 있게 된다. In this case, people using the visible light that can not be seen by the eye region (400 ~ 700nm), as well as the near infrared (~ 1150nm) even discard by the image sensor is detected, provided inside the camera module 20 and the signal is saturating the image sensor since the IR filter 41 of filter element 40, it is possible to obtain a sharp, clear image by removing the wavelength in the infrared region to be located in the camera module 20.

그리고, 야간모드는 도 2b의 도시와 같이 광량이 적은 저조도 시간대에 사용되는 것이다. Then, the night mode is used in low-light and low illumination time, as shown in Figure 2b. 이 경우에는 이미지센서에 입사되는 광량이 적어 FPN 노이즈, 저조도 색점 노이즈 등이 발생되어 깔끔한 사진을 촬영할 수 없지만, 카메라모듈(20)의 주변에 설치된 적외선 LED(30)와 필터부재(40)의 AR필터부(42)에 의해 해소할 수 있 기 때문에 적외선 LED(30)를 켠 상태에서 조작레버(43)를 이용하여 필터부재(40)를 이동시키게 되면 필터부재(40)의 AR코팅부(42)가 적외선 LED(30)에서 방출되는 적외선 영역의 파장을 모아주어 이미지센서로 입사시키기 때문에 깔끔하고 선명한 흑백의 이미지 촬영이 가능하게 된다. Although in this case it is this down FPN noise, low light saekjeom noise and the amount of light incident on the image sensor caused to take a clean picture, AR of the camera module 20, an infrared LED (30) and the filter element (40) provided in the vicinity of the filter unit 42 Let it moves the filter member 40 by the operation lever 43 is an infrared LED (30) is switched on, because it can be eliminated by the filter member 40, of the AR coating (42 ) are given together with the wavelength of the infrared emitted from the infrared LED (30) it is possible to shoot images of clean, sharp black and white, because it is incident to the image sensor.

이상, 본 발명을 바람직한 실시 예를 사용하여 상세히 설명하였으나, 본 발명의 범위는 특정 실시 예에 한정되는 것은 아니며, 첨부된 특허청구범위에 의하여 해석되어야 할 것이다. Above, been described in detail using a preferred embodiment of the invention, the scope of the present invention is not limited to the specific embodiments, it is to be interpreted by the appended claims. 또한, 이 기술분야에서 통상의 지식을 습득한 자라면, 본 발명의 범위에서 벗어나지 않으면서도 많은 수정과 변형이 가능함을 이해하여야 할 것이다. Further, if the acquisition of ordinary skill in the art chair, it will be understood that many modifications and variations are possible without departing from the scope of the invention.

상술한 바와 같이 본 발명에 따른 무선 단말기에 의하면, 상술한 바와 같이 본 발명에 따른 휴대단말기에 의하면, 적외선 LED와 필터부재를 이용하여 저조도 시에도 선명하고 깨끗한 이미지를 얻을 수 있게 됨은 물론, 필터부재가 카메라모듈까지 보호하는 역할을 하게 되는 등의 장점을 제공한다. According to the wireless terminal in accordance with the present invention as described above, the above-described, according to the portable terminal according to the present invention, as described, doemeun allows using an infrared LED and a filter member get sharp, clear images even in low light, of course, the filter element It provides advantages such that it serves to protect from the camera module.
