6.8.1 The Luma Keying Feature
The luma keying feature is an easy-to-use method of compositing two video
sources into a single image. By setting up a “key” image or clip on a black
background, it can be merged
– or overlaid – onto the primary video. The key
image is transparent in the areas of its dark background, resulting in a picture which
looks as if the key image is cut out and pasted over the primary image. This useful
function of combining images from two different sources is suitable for many
applications, such as sub-titling, labeling, advertising or logo insertion.
To apply the luma keying feature, first set the PiP window to the desired size and
location and then turn luma keying On. The PiP image will show without its
background.
The lower the luminance in the PIP window, the more transparent it becomes, thus
letting the main window image show. The higher the luminance, the less
transparent it becomes, not letting the main window show through. To use this
feature it is recommended to set the PIP image as follows: use low-luminance colors
for the background (the key image portion) and high-luminance colors for the logo.
For certain displays, the screen may flicker once for about a second
after activating or changing the luma keying setting.
We recommend that you activate luma keying after completing the
setup.
When the luma keying feature is On, any change in the setup (either
by the user or by resetting due to a setup change) may cause the
screen to flicker once. The luma keying will recover automatically after
resetting.
