image mean brightness value - non IMAQ

[alzyx]

I need to keep an eye on a control showing the mean brightness of the currently acquired image.

Since the camera drivers (Thorlabs) produce an 8-bit image, and since I need to acquire at the fastest frame rate, what is the fastest way to get the mean brightness?

Currently I'm converting the picture to IMAQ, but mayby there's a faster way?

thank you - visually seems to be simple to implement...

but - I'm a bit ashamed to admit it - I cannot understand what are a couple of the tools you used... could you please upload the VI?

Really, I'm just a novice in LV, but I'm finding really hard to grasp the huge amount of instruments it provides (reminds me a bit of when I discovered Mathematica)

thank you
