Auto Function Profile (dart E)#

Auto Function Profile camera feature 定義了攝影機在進行自動調整時如何平衡增益與 Exposure Time。

使用此功能#

設定 Auto Function Profile#

若要設定 auto function profile：

將 Gain Auto auto function 與 Exposure Auto auto function to Continuous.
將 AutoFunctionProfile 參數設為下列其中一個值：
- AntiFlicker50Hz：啟用針對 50 Hz 電源線頻率的閃爍抑制（適用於例如歐洲）。
- AntiFlicker60Hz：啟用針對 60 Hz 電源線頻率的閃爍抑制（適用於例如北美）。
- AntiFlickerAuto：啟用具備自動電源線頻率偵測的閃爍抑制。
- MinimizeExposureTime：在自動調整過程中，盡可能保持較低的 Exposure Time。
- MinimizeGain （預設）：在自動調整過程中，盡可能保持較低的增益。

範例程式碼#

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);

/* Macro to check for errors */
#define CHECK(errc) if (GENAPI_E_OK != errc) printErrorAndExit(errc)
GENAPIC_RESULT errRes = GENAPI_E_OK;  /* Return value of pylon methods */
/* Set the auto function profile to Minimize Gain */
errRes = PylonDeviceFeatureFromString(hdev, "AutoFunctionProfile", "MinimizeGain");
CHECK(errRes);
/* Set the auto function profile to Minimize Exposure Time */
errRes = PylonDeviceFeatureFromString(hdev, "AutoFunctionProfile", "MinimizeExposureTime");
CHECK(errRes);
/* Enable Gain and Exposure Auto auto functions and set the operating mode to Continuous */
errRes = PylonDeviceFeatureFromString(hdev, "GainAuto", "Continuous");
CHECK(errRes);
errRes = PylonDeviceFeatureFromString(hdev, "ExposureAuto", "Continuous");
CHECK(errRes);

# 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"
