Therefore, the camera module of the embodiment of the present invention can significantly reduce the thickness of the camera module by applying a structure that reflects the optical image of the subject with the actuator by the reflector.
도 4는 본 발명의 일 실시예의 카메라 모듈이 손떨림 보정(OIS, Optical Image Stabilization) 기능을 수행하기 위한 구성 블록도이다.4 is a block diagram illustrating a camera module according to an embodiment of the present invention for performing an optical image stabilization (OIS) function.
본 발명의 일 실시예의 카메라 모듈은 반사경을 조정하는 반사경 조정부(220)와; 흔들림을 감지하는 위치정보획득 센서(200)와; 상기 위치정보획득 센서(200)에서 감지된 흔들림 정보를 인가받아, 상기 반사경 조정부(220)을 구동시키는 손떨림 보정 구동부(210)를 포함한다. 여기서, 위치정보획득 센서(200)는 자이로 센서, 중력센서, 각속도 센서, 가속도 센서 등이 될 수 있으며, 위치정보를 획득할 수 있는 센서면 어느 것이든 가능하다.Camera module of an embodiment of the present invention and the
그러므로, 상기 위치정보획득 센서(200)에서 카메라 모듈의 흔들림을 감지하게 되면, 상기 위치정보획득 센서(200)에서 감지된 흔들림 정보를 상기 손떨림 보정 기능(OIS) 구동부(210)에서 인가받고, 상기 손떨림 보정 기능(OIS) 구동부(210)에서 상기 반사경 조정부(220)을 구동시켜, 카메라 모듈의 흔들림에 대응하여 반사경을 조정함으로써, 흔들리지 않은 피사체의 광 이미지를 촬상할 수 있는 것이다.Therefore, when the position

As a result, the camera module according to an embodiment of the present invention detects a shake in the position information acquisition sensor, and adjusts a reflector in response to the shake information of the camera module detected by the position information acquisition sensor, thereby providing an optical image stabilization (OIS) function. Can be done.
도 5와 도 6은 본 발명의 일 실시예의 카메라 모듈에서 반사경이 조정되는 것을 설명하기 위한 개념적인 도면이다.5 and 6 are conceptual views for explaining that the reflector is adjusted in the camera module of one embodiment of the present invention.
전술된 반사경 조정부는 반사경을 틸트(tilt)시키거나, 또는 직선 이동시켜 흔들리는 피사체의 광 이미지의 흔들림을 보정할 수 있게 된다.The above-described reflector adjustment unit can correct the shake of the optical image of the subject to be shaken by tilting or moving the reflector in a straight line.
즉, 도 5에 도시된 바와 같이, 'A'상태의 피사체의 광 이미지가 카메라 모듈의 흔들림에 의해, 'B'상태의 피사체의 광 이미지가 반사경으로 입사되는 경우, '101'상태의 반사경은 틸트되어 '102'상태의 반사경이 된다.That is, as shown in FIG. 5, when the optical image of the subject in the 'A' state is incident on the reflector by the shaking of the camera module, the reflector in the '101' state is It is tilted to become the reflector in the '102' state.
이때, 반사경을 회전축(P)을 중심으로 회전시켜 틸트시키는 것으로, 흔들림에 의해 피사체의 광 이미지가 흔들리더라도 상기 반사경의 틸트에 의해 엑추에이터로 입사되는 경로는 변경되지 않게 된다.At this time, by rotating the reflecting mirror about the rotation axis P, the path incident to the actuator by the tilt of the reflecting mirror is not changed even if the optical image of the subject is shaken by the shaking.
그리고, 도 6을 참조하면, 카메라 모듈의 흔들림에 의해, 피사체의 광 이미지가 'A'상태에서 'B'상태로 피사체의 광 이미지의 광축이 흔들려 반사경으로 입사되는 경우, '101'상태의 반사경은 직선 이동되어 '103'상태의 반사경이 된다.6, when the optical image of the subject is shaken by the camera module and the optical axis of the subject is shaken from the 'A' state to the 'B' state, the reflector in the '101' state is incident. Is moved linearly to become a reflector in the '103' state.
그러므로, 본 발명의 일 실시예의 카메라 모듈은 반사경을 틸트시키거나, 또는 직선 이동시켜, 손떨림 보정 기능(OIS) 구동과 같은 기능을 수행하여 카메라 모듈의 흔들림에 의한 피사체 광 이미지의 흔들림을 보정할 수 있는 것이다.
Therefore, the camera module of one embodiment of the present invention can correct the shake of the subject optical image due to the shake of the camera module by performing a function such as tilting or linearly moving the reflector to drive the camera shake correction function (OIS). It is.
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.While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
