Image processing question [message #30771]

How do I convert a color image(.jpg) to grayscale?

I am using PV-Wave's Image_Read function to read the image,
which stores all the image info in an associative array.
Do I simply take the maximum RGB intensity value at each
pixel in the 'pixels' array (xdim,ydim,3)? This gives me
a grayscale image, but I'm not sure this is the "correct"
one.
