Abstract

본 발명은 가정자동화시스템(HOME AUTOMATION SYSTEM), 도어비젼(DOOR VISION)등에 사용되는 CCD카메를 상하로 자동조절하는 장치 및 방법에 관한 것으로, 특히 방문객이 CCD카메라에 적절하게 포착되도록 CCD카메라의 촬영높이를 자동적으로 상하로 조절하는 CCD카메라 상하 자동조절장치 및 자동조절방법에 관한 것이다.The present invention relates to an apparatus and a method for automatically adjusting a CCD camera used in a home automation system, a door vision, and the like, up and down, and in particular, to photograph a CCD camera so that a visitor is properly captured by a CCD camera. It relates to a CCD camera up and down automatic adjustment device for automatically adjusting the height up and down and an automatic adjustment method.

본 발명은 방문객의 상이 없는 화면을 저장하여 기준으로하여, 방문객이 방문하는 경우의 화면과 상기 기준화면을 1라인씩 비교하여 방문객의 얼굴의 윗부분 또는 아랫부분이 잘리거나해서 방문객의 얼굴식별이 어려운 경우에 스핀들전동기로 카메라프레임을 상하방으로 이동시켜서 방문객의 얼굴을 정확하게 포착하도록 하는 것이다.The present invention stores a screen without a visitor's image as a reference, and compares the screen when the visitor visits with the reference screen by one line, so that the upper part or the lower part of the visitor's face is cut off or difficult to identify the visitor's face. In this case, the spindle motor is used to move the camera frame up and down to accurately capture the visitor's face.
