[C/C++]

pValue [out,retval]  
Pointer to the current exposure value  
Value [in]  
The exposure value to be set

Example


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

Private Sub
 Form_Load()

HScroll1.Value = ActiveGeni1.ExposureTimeAbs
HScroll1.Min = ActiveGeni1.GetFeatureMin ("ExposureTimeAbs")
HScroll1.Max = ActiveGeni1.GetFeatureMax ("ExposureTimeAbs")
ActiveGeni1.Acquire=
True

End Sub


Private Sub
 HScroll1_Scroll()

ActiveGeni1.ExposureTimeAbs = HScroll1.Value

End Sub

 

Remarks


This property changes the integration time of the camera's sensor to a sub-value of the frame period. 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 ExposureTime or ExposureTimeAbs feature per GenICam standard.
