Lum (luminance key/self key):
This is for creating the key signals from the luminance component of the key fill signal.
Linear (linear key/EXT key):
This is for creating the key signals from the luminance component of the key source signal.
It is used when the key source signal and key fill signal are different.
Since the luminance key is operated as a self key, the key fill signals are used as the key source signals.
When the luminance key has been selected as the downstream key type, the key signals will remain
unchanged even when the key source signals are switched.
Furthermore, when “Lum” is selected, the DSK button in the crosspoint area changes to lighting in amber (key
fill bus selection status).
When using the linear key, use material with a black background and white characters or shape to be combined
by the key as the key source signal.
Material which is not black and white may not be combined clearly.
Material with a white background and black characters, etc. can be reversed using the key invert function for
use.
