1. Key Type
As the chroma key, a key signal is created using a specific
hue as a reference.
For instance, the key signal is created by detecting the
colour of the background from the image of a person
standing in front of a specific background colour, and
another background is combined.
This unit uses an area system whose area is designated
by a rectangular frame. The result of averaging the colours
of the pixels inside that area is used as the chroma key
reference colour (key reference), and the maximum
deviation from the average value is used as the radius of the
chroma key oval.
Chroma keys faithful to the chroma space sample (area 
in the figure) can be generated.
