Exceptions
ExceptionDescription
Thrown if device is in wrong state.
Thrown if device does not support capability.
Thrown if the .NET debugger is used and the function evaluation requires all threads to run.
Remarks
Call this property only when device is opened (State == DeviceState.Opened).

Supported pixel types can be received by the GetSupportedNoiseFilters method.
Example
This example shows how to apply automatic noise filter to images acquired from the device.
Public Sub ScanColorImageWithNoiseFilter(ByVal device As Device)
    device.ShowUI = False
    device.DisableAfterAcquire = True
            
    device.Open()
    device.PixelType = PixelType.RGB
    device.UnitOfMeasure = UnitOfMeasure.Inches
    device.Resolution = New Resolution(300.0F, 300.0F)
    device.NoiseFilter = NoiseFilter.Auto
            
    device.Acquire()
End Sub
public void ScanColorImageWithNoiseFilter(Device device)
{
    device.ShowUI = false;
    device.DisableAfterAcquire = true;
            
    device.Open();
    device.PixelType = PixelType.RGB;
    device.UnitOfMeasure = UnitOfMeasure.Inches;
    device.Resolution = new Resolution(300f, 300f);
    device.NoiseFilter = NoiseFilter.Auto;
            
    device.Acquire();
}
