Key Window
A powerful facility exists in PREFIX to control which
areas of the picture are processed. This can be
found in the
Key Window
sub-menu. The key
window can be set up as a basic split or a user
definable area. The options available are:-
H-Split
V-Split
Box
User
The user defined key window could be used to
apply processing to a specific area of the picture.
The coordinates are set in the
Set User
sub-menu.
The coordinate pairs are specified as top-left and
bottom right, ( X1,Y1 ) and ( X2,Y2 ). The range of
values for X is 0 to 719 pixels . The range of values
for Y is 0 to 285 lines in 625 line standards and 0 to
242 lines in 525 line standards.
H-Repeat
H-Repeat performs a horizontal repeat so that the
left half of the picture is repeated on the right half of
the picture.
When key window is selected the signal processing
is applied to the shaded area. It is possible to invert
the sense of the key window so that processing is
applied to the other part of the picture instead.
