Mode of operation for the noise reduction algorithm.
The noise reduction algorithm attempts to improve image quality by removing excessive noise added by the capture process, especially in dark conditions. OFF means no noise reduction will be applied by the camera device.
FAST/HIGH_QUALITY both mean camera device determined noise filtering will be applied. HIGH_QUALITY mode indicates that the camera device will use the highest-quality noise filtering algorithms, even if it slows down capture rate. FAST means the camera device will not slow down capture rate when applying noise filtering.
Possible values:
