摘要： PROBLEM TO BE SOLVED: To objectively and concretely evaluate the identification performance of a visible camera to a noise according to numerics. SOLUTION: The arithmetic operation of noise equivalent NEXD, NEYD and NEZD is performed from tristimulus values B X , Y and Z of the reflected rays of light of a visible camera 6, tristimulus values X, Y and Z at a signal side and tristimulus values X N , Y N and Z N of a noise. The noise equivalent NEXD, NEYD and NEZD are converted into parameters ΔL * , Δa * and Δb * in an L * a * b * color system. The arithmetic operation of the numerics of noise equivalent luminance difference NEED in an Lab space is performed from the parameters ΔL * , Δa * and Δb * in the L * a * b * color system. Thus, it is possible to express the noise equivalent luminance difference in a three-dimensional color space, and to objectively and concretely evaluate the identification performance of a visible camera to a noise according to the numerics.
