8.7 Fixed Pattern Noise Artifact
With FL3-U3-13Y3, an internal sensor artifact may cause fixed pattern noise (FPN) at high saturation points on an
image. FPN most commonly manifests as vertical stripes or lines. To reduce this issue, Point Grey applies flat field
correction to the camera. Adjusting image parameters to avoid over saturation also minimizes this effect.
The mechanism to correct FPN is hard-coded into the camera firmware. It is on by default but can be turned off by
the user.
