Abstract

본 발명은 캠코더의 관한 것으로, 특히 포커싱을 위한CCD(Charge Coupled Device)를 추가하여 자동촛점조절(Autofocusing)속도를 향상시켜 시스템을 효율적으로 운용할 수 있는 캠코더의 자동좃점 조절장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camcorder, and more particularly, to an autofocus control apparatus of a camcorder capable of efficiently operating a system by adding a Charge Coupled Device (CCD) for focusing to improve an autofocusing speed.

상기와 같은 본 발명의 캠코더의 자동촛점 조절장치는 일직선상에 각각 분리되어 평행으로 위치하여 다른 기능을 수행하는 복수개의 렌즈와, 상기 렌즈의 후방에 평행하게 위치하여 포커싱 동작을 수행하는 마스터렌즈와, 상기 전 렌즈의 일직선상에 평행으로 위치하여 피사체의 광학적 영상을 전기적 신호로 변환하는 걸상용 CCD를 구비한 캠코더의 줌 유닛에 있어서, 상기 결상용 CCD의 전방에 마스터렌즈와 일정간격을 두고, 상기 전 렌즈의 일직선상에 45°의 각도를 갖고 위치하여 피사체 광을 분리하여, 분리된 광의 일부를 90°반사시키고 나머지의 피사체 광은 투과하는 빔 스플리터와, 상기 빔 스플리터의 일측에 빔 스플리터에 대응하여 평행되게 위치하여 피사체의 거리변화에 따라 결상 포인트가 달라지는 촛점조절용 CCD를 포함하여 이루어진다.The automatic focus control apparatus of the camcorder of the present invention as described above is separated in a straight line and positioned in parallel and a plurality of lenses to perform different functions, and the master lens to be positioned parallel to the rear of the lens to perform a focusing operation; And a zoom unit of a camcorder having a slit CCD positioned in parallel with the front lens and converting an optical image of a subject into an electrical signal, wherein the zoom unit has a predetermined distance in front of the imaging CCD. A beam splitter that is positioned at an angle of 45 ° on a straight line of the front lens to separate object light, reflects a part of the separated light 90 °, and transmits the remaining object light to a beam splitter on one side of the beam splitter; And a focusing CCD that is positioned in parallel to each other and that the imaging point is changed according to the distance change of the subject.
