The Confusing Color line of the Color deficiency in Panel D-15 using CIELab Color Space

CIELab 표색계를 이용한 Panel D-15의 색각이상 혼돈색 line 연구

In order to analyze of the color perception Farnsworth Test Panel D-15 in the CIELab color space coordinates, it was measured by the reflectance spectrum of the 380~780nm wavelength regions. The Test Panel D-15 was situated in the near origin point of higher the saturation in CIELab coordinates (a, b). Normal person perceived to the similar color for the color of small color difference, and color deficiency person depended on the confusing color line and the neutral point unconcerned with the color difference. In case of Ptotanopia, Deutrnopia, r-g defect, y-b defect with the color deficiency, the neutral points position (a,b) were each (2.12,1.02), (4.25,2.05), (2.51,0.25), (1.20,-1.10).

색각 검사용 Farnsworth Test Panel D-15를 CIELab color space 좌표에서 분석하기 위해 380~780nm의 반사광 spectrum 세기를 측정하였다. Test Panel D-15는 CIELab의 좌표(a,b)상에서 채도가 앞은 원점 근방에 위치하였다. 정상인은 색 차가 작은 색을 비슷한 색으로 지각하였고, 색각 이상자는 색차와 무관한 혼돈색 line과 중성점에 의존하였다. 색각이상인 제1색각 이상, 제2색각 이상, r-g defect, y-b defect의 경우 중성점 위치(a,b)는 각각(2.12, 1.02), (4.25, 2.05), (2.51, 0.25), (1.20, -1.10)였다.
