8.12.6 Auto Function Profile
If you want to use the gain auto function and the exposure auto function at the same time, the auto
function profile feature also takes effect. The auto function profile specifies whether the gain or the
exposure time will be kept as low as possible when the camera is making automatic adjustments to
achieve a target average gray value for the pixel data from the Auto Function ROI that was related
to the gain auto function and the exposure auto function. By default, the auto function profile feature
minimizes gain.
If you want to use the gain auto and the exposure auto functions at the same time, you should set
both functions for the continuous mode of operation.
Setting the camera with Basler pylon to use the gain auto function and the exposure auto function
at the same time is a several step process:
1. Set the value of the Auto Function Profile parameter to specify whether gain or exposure time
will be minimized during automatic adjustments.
2. Set the value of the Gain Auto parameter to the "continuous" mode of operation.
3. Set the value of the Exposure Auto parameter to the "continuous" mode of operation.
You can set the auto function profile from within your application software by using the pylon API.
The following code snippet illustrates using the API to set the auto function profile. As an example,
Gain Auto is set to be minimized during adjustments:
// Use Gain Auto and Exposure Auto simultaneously
camera.AutoFunctionProfile.SetValue(AutoFunctionProfile_MinimizeGain);
camera.GainAuto.SetValue(GainAuto_Continuous);
camera.ExposureAuto.SetValue(ExposureAuto_Continuous);
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon API and the pylon Viewer, see Section 3.1 on page 43 .
