Convert IEEE 1394 Cameras color image into greyscale

[Metron]

How can I directly convert a color image (RGB32, live image from IEEE 1394 cameras) into greyscale image (U8) ?

Because the find object function cannot used at color image (RGB32)

At that moment, I can only save the color image into file, then open this file as U8 format. 

my camera is PROSILICA EC1380C

interface : IEEE 1394

driver : NI-IMAQ IEEE1394 for cameras

Thanks !

Hi Metron,

If you have Vision, you can convert a RGB image to grayscale by using the IMAQ ExtractSingleColorPlane and extracting intensity or luminance.
