Example

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

Private Sub Form_Load()
ActiveDcam1.Acquire=True
HScroll1.Value = ActiveDcam1.Sharpness
HScroll1.Min = ActiveDcam1.GetSharpnessMin
HScroll1.Max = ActiveDcam1.GetSharpnessMax
End Sub

Private Sub HScroll1_Scroll()
ActiveDcam1.Sharpness = HScroll1.Value
End Sub

Remarks

This property changes the sharpness of the video by modifying parameters of the camera's differential circuitry. The valid property range is reported by the GetSharpnessMin and GetSharpnessMax methods. Note that the property is available only if the currently selected camera supports software sharpness control.
