What does ae_exposure_period do?
-
Hello, I am testing the ar0144 camera with the ae_mode set to "lme_msv" and I don't see the "ae_exposure_period" making any signifigant change. I set it to "1.0" then "1.5" and the images look exactly the same, and it seems like there is no different between the "recovery" time when going from dark to light. I'm wondering what this setting does because I believe it works different then what I am assuming.

@mkriesel , the exposure and gain period parameters should be set to 1. They were used a long time ago for Auto Exposure control for ov7251 camera, which would have weird image flicker issues if you updated gain every frame, so we would use ae_gain_period set to 2. The issue with ov7251 was also resolved a while ago and it supports gain period of 1.
These parameters specify the update period (in frames) for sending out the new gain and exposure from the AE algo. So these parameters should be set to 1, which is the default for AR0144.
There is no practical reason to use any value other than 1.
