1.3.7 2D & 3D Digital Noise Reduction
The camera features 2 types of noise reduction: 2D temporal noise reduction (NR in the
OSD menu) and 3D spatial noise reduction (CAMERA 3D NR). 2D noise reduction helps
to limit the appearance of noise (graininess in the camera image) around stationary ob-
jects. 3D noise reduction accomplishes the same process for moving objects as well, pro-
viding clearer images in low light conditions. Removing noise from the camera image
reduces your recording file size and makes videos clearer and more detailed.
To configure noise reduction:
1. Use the on-screen arrow keys to navigate to CAMERA SETTING and click Enter.
2. Select EXPOSURE SETTING and click Enter.
3. Select NEXT PAGE and click Enter.
