3.4.5 Noise Reduction
The camera provides multiple Noise Reduction options for delivering optimized image quality, especially in extra low
light conditions.
3DNR
With the 3D Noise Reduction function, the processor analyzes the differences between successive frames to adjust
pixels and improve image quality. 3DNR generates better de-noising effects than 2DNR, but might create motion blur
on moving objects in the field of view.
Different levels of 3DNR are provided, including Low, Mid and High. A higher level of 3DNR generates relatively
enhanced noise reduction.
2DNR
With the 2D Noise Reduction function, the processor analyzes individual frames of video to eliminate environmental
noise signals so that the highest quality image can be produced even in low light conditions.
Select On to turn on the 2DNR function. Select Off to turn off the 2DNR function.
ColorNR
In a dark environment or an environment with insufficient light and if the camera is in color mode, ColorNR (Color
Noise Reduction) can eliminate color noise.
Three levels of ColorNR, including Low, Mid and High, are provided. A higher level of ColorNR generates relatively
enhanced noise reduction.
3.4.6 WDR Function
The Wide Dynamic Range (WDR) function serves to solve high contrast or changing light issues to allow for enhanced
video display.
Level options for the WDR function include Low, Mid and Hi. The higher the level, the wider the dynamic range. In
this way, the camera can catch a greater scale of brightness.
3.4.7 Digital Zoom
Select On to enable the Digital Zoom function. Select Off to turn the function off.
3.4.8 Backlight
The Backlight function is available when the video format is set to 60fps or 50fps under TV System (see section
3.4.11).
Backlight Compensation prevents the center object from being too dark in surroundings where excessive light is
behind the center object.
Select On to enable the Backlight function. Select Off to turn the function off.
3.4.9 Image Stabilizer
The Image Stabilizer function is only available when the video format is set as “WDR 2 Shutter” under TV System (see
section 3.4.11). With the Image Stabilizer function, the camera can keep the image steady and suppress vibrating
effects on images caused by external vibration. Follow these steps to activate the function:
IR Heating
With the IR Heating function, the IR LED will be turned on to heat up the camera under 14 degree Celsisus.
IR heating and IR function work independently.
