Abstract

In this paper, We implemented discriminating system for various surround illuminants using photo sensor. To discriminate surround illuminants of display device we implemented discriminating system using photo sensor which has output of Ye and Cy. Experimental results shows that we could discriminate surround illuminants by output voltage ratio (Ye/Cy) of photo sensor in the variable luminous intensity of surround illuminants.

본 논문에서는 광센서를 이용하여 컬러 디스플레이 장치를 사용하는 다양한 주위 조명광을 판별할 수 있는 시스템을 구현하였다. 디스플레이를 사용하는 외부 조명광을 판별하기 위해서 Ye와 Cy 두 출력을 갖는 광센서를 사용하여 조명광 판별 시스템을 구현하였고, 구현한 실제 시스템에 대한 실험 결과 조도가 변하는 다양한 조명광에 대해서 광센서의 출력 전압비(Ye/Cy)로 조명광의 판별이 가능한 것을 확인하였다.
