摘要

PPROBLEM TO BE SOLVED: To objectively and concretely evaluate the identification performance of a visible camera to a noise according to numerics. PSOLUTION: The arithmetic operation of noise equivalent NEXD, NEYD and NEZD is performed from tristimulus values BSBX/SB, 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 XSBN/SB, YSBN/SBand ZSBN/SBof a noise. The noise equivalent NEXD, NEYD and NEZD are converted into parameters ΔLSP*/SP, ΔaSP*/SPand ΔbSP*/SPin an LSP*/SPaSP*/SPbSP*/SPcolor system. The arithmetic operation of the numerics of noise equivalent luminance difference NEED in an Lab space is performed from the parameters ΔLSP*/SP, ΔaSP*/SPand ΔbSP*/SPin the LSP*/SPaSP*/SPbSP*/SPcolor 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.

要解决的问题：根据数字客观，具体地评估可见摄像机对噪声的识别性能。

解决方案：噪声当量NEXD，NEYD和NEZD的算术运算是根据可见相机6的反射光的三刺激值B X ，Y和Z执行的，信号侧的Y和Z以及噪声的三刺激值X N ，Y N 和Z N 。等效噪声NEXD，NEYD和NEZD在L中转换为参数ΔL * ，Δa * 和Δb * * a * b * 颜色系统。 Lab空间中的噪声等效亮度差NEED的数值的算术运算是根据参数＆ L * ，＆ a * 和＆ b * a * b * 颜色系统中的> * 。因此，可以在三维色彩空间中表达噪声等效亮度差，并且可以根据数值客观地，具体地评估可见摄像机对噪声的识别性能。
