Auto Function Profile (dart E)#

Auto Function Profile 相机功能定义了相机进行自动调整时如何平衡增益和曝光时间。

该功能的使用#

设置自动功能配置文件#

要设置自动功能配置文件：

设置 Gain Auto auto function and the Exposure Auto auto function to Continuous.
设置 AutoFunctionProfile 参数设置为以下值：
- AntiFlicker50Hz: Enables flicker reduction for a power line frequency of 50 Hz (applies to, e.g., Europe).
- AntiFlicker60Hz: Enables flicker reduction for a power line frequency of 60 Hz (applies to, e.g., North America).
- AntiFlickerAuto: Enables flicker reduction with automatic power line frequency detection.
- MinimizeExposureTime: The exposure time is kept as low as possible during the automatic adjustment process.
- MinimizeGain (default): The gain is kept as low as possible during the automatic adjustment process.

C++ (Native)C++ (Generic)C#C (Generic)Python

// Set the auto function profile to Minimize Gain
camera.AutoFunctionProfile.SetValue(AutoFunctionProfile_MinimizeGain);
// Set the auto function profile to Minimize Exposure Time
camera.AutoFunctionProfile.SetValue(AutoFunctionProfile_MinimizeExposureTime);
// Enable Gain and Exposure Auto auto functions and set the operating mode to Continuous
camera.GainAuto.SetValue(GainAuto_Continuous);
camera.ExposureAuto.SetValue(ExposureAuto_Continuous);

INodeMap& nodemap = camera.GetNodeMap();
// Set the auto function profile to Minimize Gain
CEnumParameter(nodemap, "AutoFunctionProfile").SetValue("MinimizeGain");
// Set the auto function profile to Minimize Exposure Time
CEnumParameter(nodemap, "AutoFunctionProfile").SetValue("MinimizeExposureTime");
// Enable Gain and Exposure Auto auto functions and set the operating mode to Continuous
CEnumParameter(nodemap, "GainAuto").SetValue("Continuous");
CEnumParameter(nodemap, "ExposureAuto").SetValue("Continuous");

// Set the auto function profile to Minimize Gain
camera.Parameters[PLCamera.AutoFunctionProfile].SetValue(PLCamera.AutoFunctionProfile.MinimizeGain);
// Set the auto function profile to Minimize Exposure Time
camera.Parameters[PLCamera.AutoFunctionProfile].SetValue(PLCamera.AutoFunctionProfile.MinimizeExposureTime);
// Enable Gain and Exposure Auto auto functions and set the operating mode to Continuous
camera.Parameters[PLCamera.GainAuto].SetValue(PLCamera.GainAuto.Continuous);
camera.Parameters[PLCamera.ExposureAuto].SetValue(PLCamera.ExposureAuto.Continuous);

# Set the auto function profile to Minimize Gain
camera.AutoFunctionProfile.Value = "MinimizeGain"
# Set the auto function profile to Minimize Exposure Time
camera.AutoFunctionProfile.Value = "MinimizeExposureTime"
# Enable Gain and Exposure Auto auto functions and set the operating mode to Continuous
camera.GainAuto.Value = "Continuous"
camera.ExposureAuto.Value = "Continuous"
