Spatial
The spatial noise reduction filter operates on luminance only and uses nearby samples to
average out noise. Picture objects and edges are detected and the filtering disabled.
You can set sensitivity of edge detection either automatically with Auto mode, or manually
with the Threshold slider.
•
Level:
Adjusts the level of noise reduction applied to the signal. The adjustment range
is 0 to 7. The preset value is 0.
•
Mode:
Choose between automatic and manual filtering.
In Auto mode, the background noise level is measured and the threshold set to give a
good compromise between noise reduction and picture softness. In Manual mode,
increasing the Threshold value allows for pictures with higher background noise.
Note: For best results in Manual mode, always set the threshold to the lowest value
for the desired noise reduction.
•
Threshold:
Adjusts the noise reduction threshold. The adjustment range is 1 to 4.
The preset value is 1.

screen shows the image with noise reduction, and the other side of the screen shows the
image without noise reduction.
