Figure 2: Frame average: Functional principle

This method is well known and is used in the same or a similar way in all flat screen televisions. The

amount of de-noising can be set with the slope factor: the smaller the value, the greater the

feedback and therefore the de-noising but also the motion blur in the image:

Slope: 256 = 100 % pixel_difference = 100 % signal_in

Figure 3: Frame average: Slope

There are no delays with this option because de-noising is recursive and the Signal

OUT

is extracted

before the frame memory.

Using wxPropView

Using the frame average mode "mvDynamic", you have to do the following step:

Start wxPropView and1.

connect to the camera.2.

Then specify in "Setting -> Base -> Camera -> GenICam -> Device Control" which

processing unit of the camera should do the frame averaging, e.g. unit 0 should do the frame

averaging

"mv Device Processing Unit Selector = 0"

"mv Device Processing Unit = mvFrameAverage".

Afterwards, "mv Frame Average Control" is available.

Now open "Setting -> Base -> Camera -> GenICam -> mv Frame Average Control" and4.

select "mv Frame Average Mode = mvDynamic".5.

Set the slope, e.g. 5000: "mv Frame Average Slope = 5000".6.

Activate frame averaging by setting "mv Frame Average Enable = 1".7.
