4 The image is displayed enlarged in the [100% view]
or [200% view].
You can check the noise reduction effect.
In the [50% view] or [Fit to window] display, it is difficult to check
the noise reduction effect, so noise reduction is not applied.
To check the noise reduction effect, enlarge the image and
display it
Noise reduction is applied when the image is displayed enlarged in the
[100% view] or the [200% view] in the edit window or the edit image
window. It is not applied in the [50% view] or the [Fit to window] display
or any other window as the noise reduction effect is difficult to check.
If [Chrominance noise] has been set, color bleeding may occur
along with reduction of noise.
For a list of tool palette functions, refer to p.91.
