Abstract

캠코더를 이용한 피사체 촬영에 있어서, 피사체의 크기 및 거리를 알수 없었던 점을 개선하여 피사체의 거리 및 크기를 알려 주도록 하는 것으로 오토 포커싱을 가능케하는 포커스 렌즈 구동용 스텝모터의 스텝 포지션을 체크하여 카메라와 피사체와의 거리를 환산해 내고 렌즈와 CCD와의 촛점거리, CCD내의 피사체 크기를 확인하여 CCD내의 피사체 크기를 촛점거리로 나눈후 이를 피사체까지의 거리로 곱해 주므로써 실제 피사체 크기(높이)를 알수 있도록 하는 것이다.When shooting a subject using a camcorder, it is possible to improve the fact that the size and distance of the subject are unknown so that the distance and size of the subject can be known so that the step position of the step motor for the focus lens driving that enables auto focusing can be checked. Calculate the distance from the lens, check the focal length between the lens and the CCD, and the subject size in the CCD. Divide the subject size in the CCD by the focal length and multiply it by the distance to the subject so that you can see the actual subject size (height). will be.
