Conversion from either RGB or HSL to Grayscale color spaces

[Pacsoft]

Is there an NIVision function that allows easy and fast conversion from either RGB or HSL images into grayscale images ? I know that I can directly manipulate each pixel to get a grayscale image, but want to know if there is a faster way by using NIVision-only functions. Thanks !

I would recommend extracting the Luminance plane using the IMAQ ExtractSingleColorPlane.vi - this gives the best greyscale representation from a color image.

Sorry - didn't realize you were using CVI:

The CVI function is:  imaqExtractColorPlanes

The 'IMAQ Vision for LabWindows/CVI Function Reference Help' will detail the usage of this function

Ok. I understand what you are saying, and makes a lot of sense. Thanks a lot !
