Auto-exposure regions of interest: Clarification about region weights

Hello,

I’m looking at the setAeRegions Argus::IAutoControlSettings::setAeRegions( const std::vector< AcRegion > & regions ) API method.

For each AcRegion we can specify a certain weight. I would like some help understanding the function of these weights.

Specifically:

  1. What’s the numerical range of the the weights?
  2. In case of multiple regions, should the weights be normalized to sum to 1? For example if I want two regions with equally high priority, should I set to the weights to (0.5, 0.5) or (1.0 1.0)?
  3. When setting auto-exposure regions, will the auto-exposure exclusively look at these regions or still look at the rest of the frame to some extent?

Thank you,
David

  1. It’s 0 -1
  2. No need to sum to 1
  3. Still looking at whole frame.
