Camera Auto Exposure Gain
: This is enabled by selecting it in the dropdown menu. Choose other
settings for manual exposure and gain control.
AutoGain ROI
: Sets the region that auto gain is calculated.
AutoGain Min Range
: The system will stop changing if the mean is within this value of target. A small
non-zero value can reduce the auto gain solution from bouncing around. This value should be 10 or
less.
AutoGain Rate
:
This is the
auto gain step size. Larger values force larger auto gain steps. 32 is the
default.
Minimum/Maximum Exposure
:
Limits the exposure range.
Auto gain algorithm notes:
•
For best image quality, the system attempts to do the following in order: maximize exposure,
analog gain, digital gain.
•
To make a scene brighter first increase the exposure. If the exposure is at maximum increase the
analog gain (luma). If the analog gain is set at maximum, increase the digital red, green and blue
gains. Auto gain moves the RGB gains together, increasing or decreasing them by equal amounts.
•
To make a scene darker reduce digital gain, reduce analog gain, and then reduce exposure.
