Adjust the position and size of the sample selector, to specify the color to 
be used as the basis of chroma keying (typically a blue background).

a) The setting ranges depend on the signal format, screen aspect ratio, and size settings.

Select [Auto Start] in the <Auto> group.

This executes an auto chroma key based on the color specified by the 
sample selector, and displays the composite image on the monitor.

When the key active function is on, the composite image is output to the 
monitor, and you can watch the monitor while manually adjusting the keying. 
When the key active function is off, only the foreground image appears. Set 
this off when manually adjusting color cancel (see the next section).
Use the following procedure.

In the Chroma Adjust menu, set [Key Active] on.

Adjust the following parameters.

If the background color is leaking into the foreground video, turning the color 
cancel function on allows you to eliminate this leakage.
Use the following procedure.

In the Chroma Adjust menu, turn [Key Active] off.

Only the foreground image appears on the monitor.

In the <Color Cancel> group, set [Color Cancel] on.
