曝光开始延迟#

Exposure Start Delay 相机功能使您可以确定从检测到触发信号到实际开始曝光之间的时间。

曝光开始延时的长短取决于相机型号、及各种相机功能的设置，例如 Exposure Mode、Exposure Time 模式或 Sensor Bit Depth。

该功能的使用#

确定 Exposure Start Delay#

To determine the exposure start delay at the current settings, get the value of the BslExposureStartDelay parameter. The exposure start delay is measured in microseconds.

示例代码#

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

// Determine the exposure start delay at the current settings
double d = camera.BslExposureStartDelay.GetValue();

INodeMap& nodemap = camera.GetNodeMap();
// Determine the exposure start delay at the current settings
double d = CFloatParameter(nodemap, "BslExposureStartDelay").GetValue();

// Determine the exposure start delay at the current settings
double d = camera.Parameters[PLCamera.BslExposureStartDelay].GetValue();

/* 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 */
double d = 0;
/* Determine the exposure start delay at the current settings */
errRes = PylonDeviceGetFloatFeature(hdev, "BslExposureStartDelay", &d);
CHECK(errRes);

# Determine the exposure start delay at the current settings
d = camera.BslExposureStartDelay.Value
