영어에서 DEFOCUS 의 뜻은 무엇인가요?

디 포커스 수차

Defocus aberration

광학에서 디 포커스는 이미지에 초점이 맞지 않는 수차입니다. 이 수차는 카메라, 비디오 카메라, 현미경, 망원경 또는 쌍안경을 사용하는 사람에게는 익숙합니다. 광학적으로, 디 포커스 (defocus)는 최적의 초점면 또는면으로부터 광축을 따라 이동하는 것을 말한다. 일반적으로 디 포커스는 이미지의 선명도와 대비를 감소시킵니다. 어떤 장면에서 선명하고 고 대비 인 가장자리가 점진적인 전환이됩니다. 장면의 세부 묘사가 흐리거나 보이지 않게됩니다. 거의 모든 이미지 - 형성 광학 장치는 디 포커스를 최소화하고 이미지 품질을 최대화하기 위해 어떤 형태의 포커스 조정을 통합합니다. 주어진 초점 이동량에 대한 이미지 흐려짐의 정도는 반대로 렌즈 F- 넘버에 좌우됩니다. f / 1.4 ~ f / 2.8과 같은 낮은 f 값은 초점 흐리게에 매우 민감하며 초점 심도가 매우 낮습니다. f / 16 ~ f / 32 범위의 높은 f 값은 초점 흐리게에 매우 강하며 초점 심도가 높습니다. F 번호의 제한적인 경우는 아마도 f / 100에서 f / 1000까지 작동하는 핀홀 카메라입니다.이 경우 모든 물체는 핀홀 구멍으로부터의 거리에 거의 관계없이 초점을 맞 춥니 다.

In optics, defocus is the aberration in which an image is simply out of focus. This aberration is familiar to anyone who has used a camera, videocamera, microscope, telescope, or binoculars. Optically, defocus refers to a translation along the optical axis away from the plane or surface of best focus. In general, defocus reduces the sharpness and contrast of the image. What should be sharp, high-contrast edges in a scene become gradual transitions. Fine detail in the scene is blurred or even becomes invisible. Nearly all image-forming optical devices incorporate some form of focus adjustment to minimize defocus and maximize image quality. The degree of image blurring for a given amount of focus shift depends inversely on the lens f-number. Low f-numbers, such as f/1.4 to f/2.8, are very sensitive to defocus and have very shallow depths of focus. High f-numbers, in the f/16 to f/32 range, are highly tolerant of defocus, and consequently have large depths of focus. The limiting case in f-number is the pinhole camera, operating at perhaps f/100 to f/1000, in which case all objects are in focus almost regardless of their distance from the pinhole aperture.
