Take a picture of the background and compute the standard deviation of it. How about that? Or do the same to a smooth part of the image. Should work if you have additive Gaussian noise, but there are lots of different kinds of noise. Can you post an image and say what you want to do with this information?

There's additive Gaussian noise, Poisson noise, 1/f noise, shot noise, and other kind of stochastic noise. In addition there are systematic noises like fixed pattern noise, quantization noise, etc. The Internet is a better source of education for you than I am, so I encourage you to learn more about noise. I'm not able to give you a course on noise here in the Answers forum for many reasons.
