This function reduces the noise generated in the image. Although noise 
reduction is applied at all ISO speeds, it is particularly effective at high 
ISO speeds. At low ISO speeds, the noise in the darker parts of the 
image (shadow areas) is further reduced. Change the setting to suit the 
noise level.

High ISO Speed Noise Reduction
With [High] or [Multi Shot Noise Reduction], the maximum burst for 
continuous shooting will greatly decrease.
If you play back a 1+73 or 1 image with the camera or print an image 
directly, the effect of the high ISO speed noise reduction may look minimal. 
Check the noise reduction effect or print noise-reduced images with Digital 
Photo Professional (provided software, p.364).
