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 = ActiveGige1.ExposureTimeAbs
HScroll1.Min = ActiveGige1.GetFeatureMin ("ExposureTimeAbs")
HScroll1.Max = ActiveGige1.GetFeatureMax ("ExposureTimeAbs")
ActiveGige1.Acquire=True
End Sub

Private Sub HScroll1_Scroll()
ActiveGige1.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.
