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 4 conspicuous with slow shutter speeds.

Advanced shooting functions
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.

•
[NOISE REDUCTION] is always set to [ON] when the
f
mode is set to [

•
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 ([

•
This function may not work effectively with some shooting conditions or
subjects.
