focal ratio oor Koreaans

focal ratio

naamwoord

In photography, the diameter of the aperture expressed in terms of the focal length of the camera lens. The greater the f-number, the less light reaches the film and the more in focus the objects in the foreground and the background will be. For example, with an f-number = 16 the objects in the far background will be in focus. Whereas, with an f-number = 2 the background will be blurry (while foreground objects are in focus).

voorbeelde

Maximum magnification ratio at respective focal lengths is indicated on the lens barrel, thus it is easy to see what the object size will be at the sensor.
각 초점거리에서의 최대 확대 배율을 렌즈배럴에서 확인이 가능하며 따라서 센서에 맺히는 피사체의 사이즈를 쉽게 확인할 수 있습니다.

The present invention relates to an actuator for a camera module and, more specifically, to an actuator for a camera module which moves one or more movers on which lenses are stacked to be displaced along an optical axis and fixes the positions of the displaced movers so as to implement an auto focus for adjusting a focal length between the lenses and an image sensor according to the position of a subject, or an optical zoom function for adjusting a zoom ratio by adjusting the distance between the lenses.
본 발명은 카메라 모듈용 엑츄에이터에 관한 것으로, 더욱 상세하게는 렌즈를 탑재한 하나 이상의 이동자를 광축을 따라 변위 이동하고 변위 이동된 이동자를 위치 고정시켜, 피사체의 위치에 따른 렌즈와 이미지 센서 사이의 초점거리를 조절하는 자동 초점(Auto Focus, AF) 기능, 또는 렌즈와 렌즈 사이의 간격을 조절하여 줌 배율을 조절하는 광학 줌(Optical Zoom) 기능을 구현하도록 한 카메라 모듈용 엑츄에이터에 관한 것이다.
