adapted via this configuration.
• min, max contrast gain: range between 0.5 – 2.0. Default max contrast gain 0.0,
meaning no adaptation. If max contrast gain between 0.5 – 2.0, adaptation based on
average of latest (at least 7) license plate areas; maximum adaptation of +/- 0.0625
every 5 seconds. The adaptation is targetting on an average luminance of 152 on the
license plate area and a maximum of 20% over-saturation.
