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 Ye and Cy. Experimental results shows that we could discriminate surround illuminants effectively by using the output voltage ratio (Ye/Cy) of photo sensor in the varying luminous intensity of surround illuminants.
