TIP
Gain
The Gain controls the way digital values are assigned to
the analog signal from the camera. Lower Gain values will
increase the contrast of the image and may help to
differentiate the fiducial from the background. However, a
low Gain value may also amplify “noise” in the image.
Therefore, it is recommended that you first adjust the light
level, then adjust the Gain only if necessary.
The default value of the Gain is 255.
