Abstract

본 발명은 캠코더에서의 주움 위치 표시 장치에 관한 것으로, 특히 캠코더의 광학 뷰우 파인더(OVF)에 액정 편광판을 추가하여 주움(Zoom) 가변시에 주움 위치에 해당하는 화각을 볼 수 있는 장치게 관한 것이며, 캠코더에서의 주움 렌즈 위치를 광학 뷰우 파인더내에 표시하는 장치에 있어서, 주움 렌즈의 위치를 판독하는 제어부, 광학 뷰우 파인더내에 장착하며, 상기 제어부에 의한 주움 렌즈 위치 정보에 따라 소정의 화각을 표시하는 액정 편광판을 포함하는 것을 특징으로 하며, 캠코더에서의 광학 뷰우 파인더내에 액정 편광판을 삽입하여 캠코더의 위치 정보를 받아 이에 해당하는 화각이 액정 편광판에 표시되도록 하여 비용을 절감하고 사용하기 편리한 잇점이 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device for displaying a zoom position in a camcorder, and more particularly, to a device capable of viewing an angle of view corresponding to a zoom position when a zoom is changed by adding a liquid crystal polarizer to an optical viewfinder (OVF) of a camcorder. A device for displaying the position of a zoom lens in a camcorder in an optical viewfinder, comprising: a control unit for reading the position of a zoom lens, mounted in the optical viewfinder, and displaying a predetermined angle of view according to the zoom lens position information by the control unit. Characterized in that it comprises a liquid crystal polarizing plate, by inserting the liquid crystal polarizing plate in the optical viewfinder in the camcorder to receive the position information of the camcorder so that the corresponding angle of view is displayed on the liquid crystal polarizing plate has the advantage of saving cost and convenience.
