I found out that Luminance, Value and Intensity are from HSL, HSV and HSI color space, but surely Luminance should be replaced with lightness.

My task is to convert an image from RBG to CIE Lab. I found two ways to do it. One was discussed in http://lavag.org/topic/13885-how-to-convert-rgb-to-cie-lab/ and the other possibility is to use a function IMAQ ExtractSingleColorPlane VI. With this function is possible to directly get Luminance. What is Luminance? Is this L* in CIE Lab? And what is Intensity? http://zone.ni.com/reference/en-XX/help/370281M-01/imaqvision/imaq_extractsinglecolorplane/ thanks matej
