6.5.7 WDR Function
The Wide Dynamic Range (WDR) function is for resolving high contrast or changing light
issues in order to enhance the video display. The WDR is adjustable from “Low”, “Mid” to
“Hi”. Higher level of WDR represents wider dynamic range, so that the camera can capture a
greater scale of brightness. Press <√> to confirm the new setting.
6.5.8 Noise Reduction
The camera provides multiple Noise Reduction options for delivering optimized image quality,
especially in extra low-light conditions. Level options for 3D Noise Reduction (3DNR) include
“Low”, “Mid” and “Hi”. A higher level of 3DNR generates relatively enhanced noise
reduction.
The proprietary Smart Picture Quality (SPQ) video processing method provides clear images
even in a low-light environment and can drastically minimize motion blur. The combination of
SPQ and 3DNR at different levels yields exceptional video performance in various conditions.
Noise Reduction is adjustable from “3DNR Low”, “3DNR Mid”, “3DNR Hi”, “SPQ”, “SPQ +
3DNR Low”, “SPQ + 3DNR Mid”, to “SPQ + 3DNR Hi”. Press <√> to confirm the new
setting.
