Creates key signals from luminance components or luminance and chroma components of key fill signals.
f Since the luminance key is operated as a self key, the key fill signals are used as the key source signals.
The key signals do not change even when the key source signals are switched.
Creates key signals from luminance components of key source signals. It is used when the key source signal and key fill
signal are different.
Use source with a black background and white characters or shape to be combined by the key as the key source signal.
Source which is not black and white may not be combined clearly. Source with white background and black characters
can be used by inverting the keys with the key invert function.
Creates key signals using a specific hue of key source signals as the reference.
Creates key signals using the images on the full screen as the key source signals.
f For the full key, the images on the full screen are used as the key source signals.
The key signals do not change even when the key source signals are switched.
Generates the key signals only from the luminance components.
Generates the key signals considering the chroma components in addition to the luminance components. This item is set
when a low luminance component color is used for key signals such as when cutting blue characters.
Cuts key fill with a key signal.
Does not cut key fill with a key signal. The part of key fill not cut out with the key signal is superimposed on the
background image. This item is used when key fill source has been cut with a key signal beforehand using an external
