Gain Auto

Gain Auto is the "automatic" counterpart to manually setting the GainRaw parameter. When the
gain auto function is operational, the camera will automatically adjust the GainRaw parameter value
within set limits until a target average gray value for the pixel data from the auto function AOI is
reached.
The gain auto function can be operated in the "once" and continuous" modes of operation.
If the auto function AOI does not overlap the image AOI (see Section 8.5.3.1 on
data from the auto function AOI will not be used to control the gain. Instead, the current manual
setting for the GainRaw parameter value will control the gain.
The gain auto function and the exposure auto function can be used at the same time. In this case,
however, you must also set the auto function profile feature.
For more information about
setting the gain "manually", see Section 8.2 on

the auto function profile feature, see Section 8.5.7 on

The limits within which the camera will adjust the GainRaw parameter are defined by the
AutoGainRawUpperLimit and the AutoGainRawLowerLimit parameters. The minimum and
maximum allowed settings for the AutoGainRawUpperLimit and AutoGainRawLowerLimit
parameters depend on the current pixel format, on the current settings for binning, and on whether
or not the parameter limits for manually setting the gain feature are disabled.
The AutoTargetValue parameter defines the target average gray value that the gain auto function
will attempt to achieve when it is automatically adjusting the GainRaw value. The target average
gray value can range from 50 (near-black) to 205 (near-white) when the camera is set for an 8-bit
pixel format or from 800 (near-black) to 3280 (near-white) when the camera is set for a 12-bit pixel
format.
To set the gain auto functionality:
1. Set the value of the AutoFunctionAOIOffsetX, AutoFunctionAOIWidth, and
AutoFunctionAOIHeight parameters.
2. Set the GainSelector parameter to DigitalAll.
3. Set the value of the AutoGainRawLowerLimit and AutoGainRawUpperLimit parameters.
4. Set the value of the AutoTargetValue parameter.
5. Set the value of the GainAuto parameter for the "once" or the "continuous" mode of operation.
