Exposure Auto - Basler DART BCON SERIES User Manual

AW00136902000
To set the gain auto function:
1. Set the value of the AutoGainLowerLimit and AutoGainUpperLimit parameters.
2. Set the value of the AutoTargetBrightness parameter.
3. Set the value of the GainAuto parameter for the Once or the Continuous mode of operation.
You can set the gain auto function from within your application software by using the pylon API. The
following code snippets illustrate using the API to set the gain auto function:
// Set the lowest possible lower limit and the highest possible
// upper limit for the gain auto function
camera.AutoGainLowerLimit.SetValue(camera.AutoGainLowerLimit.GetMin());
camera.AutoGainUpperLimit.SetValue(camera.AutoGainUpperLimit.GetMax());
// Set the target average gray value to 60% of the maximum gray value
camera.AutoTargetBrightness.SetValue(0.6);
// Enable Gain Auto by setting the operation mode to Continuous
camera.GainAuto.SetValue(GainAuto_Continuous);

11.11.4 Exposure Auto

The exposure auto function will not work if the camera's exposure mode is set to
trigger width. For more information about the trigger width exposure mode, see
Section 9.2.3 on
Exposure Auto is the automatic counterpart to manually setting the ExposureTime parameter. The
exposure auto function automatically adjusts the ExposureTime parameter value within set limits
until a target brightness value for the pixel data is reached.
The exposure auto function can be operated in the Once and Continuous modes of operation.
The exposure auto function and the gain 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 exposure time manually, see Section 9.3 on
For more information about the Auto Function Profile feature, see Section 11.11.6 on
