Noise Reduction - Olympus D630 - CAMEDIA D 630 Zoom Digital Camera Advanced Manual

Glossary of terms

Noise reduction

When shooting in a dark place, the shutter speed will be slow due to less exposure
of the CCD. When shooting in long exposure, a signal is generated even from the
unexposed part of the CCD, and will be recorded as noise. When the noise reduction
activates, the camera automatically reduces the noise and makes clear shooting
possible.
