HRESULT put_ExposureTimeRaw( long Value );


Data Type [VB]

Parameters [C/C++]

pValue [out,retval]

Pointer to the current exposure value

Value [in]

The exposure value to be set

Return Values

S_OK

E_INVALIDARG

Example

The following VB example demonstrates the use of a scroll control for real-time adjustment of the exposure value.

Private Sub Form_Load()
HScroll1.Value = ActiveGige1.ExposureTimeRaw
HScroll1.Min = ActiveGige1.GetFeatureMin ("ExposureTimeRaw")
HScroll1.Max = ActiveGige1.GetFeatureMax ("ExposureTimeRaw")
ActiveGige1.Acquire=True
End Sub

Private Sub HScroll1_Scroll()
ActiveGige1.ExposureTimeRaw = HScroll1.Value
End Sub

Remarks

This property changes the integration time of the camera's sensor to a sub-value of the frame period. Depending on the camera model, the raw exposure value can be directly or inversely related to the integration time absolute value. The valid range of the exposure values can be obtained by the GetFeatureMin and GetFeatureMax methods.

Note that the property is available only if the currently selected camera supports the ExposureTimeRaw feature per GenICam standard.
