Noise reduction
When shooting in dark places, shutter speeds become slower as there is 
less light focused on the CCD. During long exposures, signals are 
generated by parts of the CCD where no light is focused and are recorded 
on the image as noise. When [NOISE REDUCTION] is set to [ON], the 
camera automatically reduces the noise to produce clearer images.
ON
Noise is reduced. Shooting time is twice as 
long as usual. Noise reduction can only be 
used when the shutter speed is slower than 
1/2 sec.
OFF
Noise is not reduced. Noise may be 
conspicuous with slow shutter speeds.
The purpose of these pictures is to illustrate the effects of noise reduction. They are 
not actual pictures.

Note
• [NOISE REDUCTION] is always set to [ON] when the 
f mode is set to [R 
NIGHT SCENE].
• When [NOISE REDUCTION] is set to [ON], the camera implements noise-
reducing processes after each shot to produce clearer images. However, 
shooting time is approximately twice as long as usual. During this time, the next 
shot cannot be taken.
• When [NOISE REDUCTION] is set to [ON], sequential shooting ([j], [i], 
[7]) is not possible.
• This function may not work effectively with some shooting conditions or 
subjects.
