Abstract
It was made of a chart by new method to be measured the contrast sensitivity for a spatial frequency, and the mean luminance of a lattice frequency was made to three forms of 25, 50, 75% and let it to be ready a CS value from 0 to
공간주파수에 따른 contrast sensitivity를 측정할 수 있는 새로운 방법으로 차트를 제작하기 위해 차트 화면 최대 luminance값을 100%로 하여, 격자주파수의 mean luminance를 25, 50, 75%의 3개형태로 만들어 CS값 0 에서
