4.
Hue
: To adjust the hue (tint) of the video output.
5.
Saturation
: To adjust the saturation (Colour intensity level) of the video output.
6.
Sharpness
: To set the sharpness of video output. Sharpness (also called Detail/Edge
Enhancement in previous OPPO players) is a video processing function that can control the image
sharpness but at the same time may cause unwanted artifacts.
For
HDMI 1
, the sharpness level can be set between -16 and +16. The default is level 0, which
turns off sharpness enhancement. The negative levels may be used to reduce or eliminate overly
sharpened video. However, the picture may appear soft. The positive levels increase the
sharpness.
•
At level 1, the player applies low level Detail Enhancement, during which the video processor
isolates the detailed parts from the original image, processes them separately and integrates
back before the final output.
•
At level 2, the player increases Detail Enhancement to a higher level. Generally, to make an
image “sharper”, we recommend using level 1 and 2.
•
At level 3 and above, the player adds Luminance Transition Improvement (LTI) and Chroma
Transition Improvement (CTI), which further sharpen the luminance transition and chroma
transition. However, we do not recommend using level 3 and above unless the source content
is poorly produced and blurry.
For
HDMI 2 & Analog
, the sharpness level can be set between 0 and +2. The default is level 0.
The higher the level, the sharper the video details are. However, too high a sharpness level may
cause while line etching around objects.
7.
Noise Reduction
: To select whether the player shall apply video noise reduction processing.
For
HDMI 1
, the noise reduction level can be set between 0 and 8. The default is level 0, which
turns off noise reduction.
•
When set to level 1, the player adjusts the picture quality by reducing the “mosquito noise”
(artifacts around the outlines of objects) and “block noise” (mosaic-like patterns caused by
video compression). These two noise reduction are also called Compression Artifacts
Reduction (CAR) and have several levels of aggressiveness.
•
When set to level 2, the player applies the Motion Adaptive Video Noise Reduction (VNR),
which handles the random noise and the film-grain noise (natural variation of picture intensity
caused by film grain). Its level is automatic because there is a noise estimator circuitry in the
video processor that calculates how much noise presents and adjusts the level of VNR
accordingly.
•
When set to 3 or 4, the player applies both CAR and Motion Adaptive VNR, with more
aggressive “block noise” reduction at level 4.
•
At level 5, the player applies aggressive CAR for low quality video content, and adds Motion
Adaptive VNR at level 6.
•
At level 7, the player applies the most aggressive CAR for very low quality video, and adds
Motion Adaptive VNR at level 8.
Remember that excessive noise reduction may cause a loss of details. We recommend using the
noise reduction function only when you encounter poorly encoded or compressed video that has
apparent noise artifacts.
