4.4.2.6 DNR (Dynamic Noise Reduction)
Dynamic Noise Reduction in video images has the following effects.
1. Images are brighter and sharper.
2. When the level of noise is reduced, the performance of a camera can apparently be
improved.
3. When it is recorded digitally, reduced noise can reduce image file size.
As the level of gain changes, the background noise in the low light level automatically
decreases.
1. Please direct the arrow to point to “DNR” on the SETUP menu by using the UP
and DOWN buttons.
2. Select the mode you would like to operate by pressing the LEFT or RIGHT
button.
