Automatically adjust brightness for the L5
This applies to both L5 cameras.
It needs an "IPU" module.
There are 3 knobs in the sensor:
- exposure time
- analog gain
- digital gain
Exposure time should probably be the first choice up to sth like 1/20 s for taking still photos, 1/5 s for preview. Anything higher than that will often be blurry. Then adjust analog gain, and finally, digital gain.
If we had access to the accelerometer, we could measure the steadiness of the camera, and adjust the exposure time to that.
The modules are not compiled in, so they probably don't need to have a strong upstream push.
