To help me with doing some signal processing on an image, I'd like to model how a digital camera works.

The camera has a bunch of pixels. What is the relationship between the value of that pixel in the resulting image, compared to the intensity of the light entering that pixel sensor?

  • Is it a linear function?
  • Is there some nonlinear response function?
  • If it is nonlinear, how can I recover or model that response function?
