2D chroma NR Eliminates the noise on the color component by non-linear noise extract fi lter.
none Disables the 2D chrominance noise extract. (Factory default)
low Enables low 2D noise extract fi lter.
middle Enables medium 2D noise extract fi lter.
high Enables high 2D noise extract fi lter.
black gain Strengthens the gain in low luminance area toward luminance signal. As the setting
becomes stronger, black gain becomes more emphasized.
When set to [none], the “B adaptation level”, “black threshold” settings will be
invalid.
none Disables the black gain. (Factory default)
low Enables low black gain fi lter.
middle Enables medium black gain fi lter.
high Enables high black gain fi lter.
B adaptation level
Sets the adjustment volume for black expansion. As the adjustment volume is
larger, the black gain becomes more emphasized.
level 1 (Factory default)
level 2 to 4
black threshold Specifi es the luminance level to enhance black element. The higher the value, the
brighter the luminance level will be.
Set specifi ed numerical value between 0 and 255. (Factory default: 0)
white gain Weakens the gain in high luminance areas toward luminance signal. This option
improves reproduction of gradation in damaged area that are seen as white due to
high luminance.
When set to [none], the “W adaptation level”, “white threshold” settings will be
invalid.
none Disables the white gain. (Factory default)
low Enables low white gain fi lter.
middle Enables medium white gain fi lter.
high Enables high white gain fi lter.
