Luma/Chroma Mode Pop-Up Menu
• Luma/Chroma Mode Pop-Up Menu : Choose one of the presets in this pop-up menu to
decide the maximum allowable chroma saturation. The normal setting of 120 should
work in most situations; however, more conservative settings are available.
Note: The number in the preset refers to the value of the combined luma and chroma
signals, mostly weighted toward the luma signal.
Options in the
Luma/Chroma Mode
pop-up menu
If you choose Custom from the Luma/Chroma Mode pop-up menu, you can use the
sliders in the Custom Luminance Limiting and Custom Saturation Limiting areas to
manually fine-tune clamping of luma and chroma levels. If any mode other than Custom
is chosen, the Custom Luminance Limiting and Custom Saturation Limiting sliders have
no effect.
Custom Luminance Limiting Controls
• Enable: Select or deselect the checkbox to turn on or turn off the Custom Luminance
Limiting controls.
