Detect Brightness / Bright Image

[kingkong404]

I'm trying to create a smart invert feature where given an image, if that image is bright it will invert it to make it dark and if its already dark leave it alone.

Is there a way to read the current brightness of an image overall?

The images im trying to invert are typically on a off white background or a dark grey background. So differentiating them should be striaght forward.

Thanks in advance for any help.
