Key; Selecting The Key Type - Panasonic AV-HS410N Operating Instructions Manual

1. Basic operations

1-3. Key

This operation combines the background image with another
image. The key definition can be adjusted, and an edge can
be added to the combined image.
Also available as materials besides KEY for combining with
the background image are PinP (picture in picture) and DSK
(downstream key).
The default settings for priority (image positioning) are as
shown in the figure below.

1-3-1. Selecting the key type

1 Press the k button to light its indicator, and display the
Key menu.
2 Use [F1] to display the Key sub menu.
3 Use [F2] to select the Type item.
Lum
(luminance key/
self key)
Linear
(linear key/
EXT key)
Chroma
(chroma key/
self key)
Full
(full key/self key)
Since the luminance and chroma keys are operated as
self keys, the key fill signals are used as the key source
signals. For the full key, the images on the full screen
are used as the key source signals.
When the luminance key, chroma key or full key has
been selected as the key type, the key signals will
remain unchanged even when the key source signals
are switched.
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.
4 When the luminance key has been selected, the chroma
component can be included in the generation of the key
signals in view of the self key application. (This does not
apply to the linear key.)
Use [F3], and select the setting using the Lum Key item.
Chroma On In addition to the luminance component, the
chroma component is also taken into account
in the generation of the key signals.
This is the setting for using a color with a low
luminance component for the key signals
(such as when defining blue characters).
Chroma Off
The key signals are generated from only the
luminance component.
5 Use [F4] to select the fill type using the Fill item.
Bus
The bus signal is used for the key fill signal.
Matte The internal fill matte is used for the key fill
signal.
14
This is for creating the key signals from
the luminance component or luminance
and chroma component of the key fill
signal.
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.
This is for creating the key signals using
a specific hue of the key fill signal as the
reference.
This is for creating the key signals using
the images on the full screen as the key
source signals.
PinP combinations are possible in
conjunction with the flying key.
