[4] KEY Setup Menu
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 color
of the background from the image of a person standing in
front of a specific background color, and another background
is combined.
This unit uses an area system whose area is designated by
a rectangular frame. The result of averaging the colors of the
pixels inside that area is used as the chroma key reference
color (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.
