Whether the stencil is
O n
or
Off
can be determined by enabling
the
Stencil Hide/Show
selection i n Paint Menu
4.
When you
return to the image, areas where the stencil is
On
will be
displayed brighter. Areas where the stencil is
Off
will appear
normal. References to the
stencil on
a reas i n this description
always
refer to the brightened area s.
N OTE:
that the stencil
On
and stencil
Off
regions can be
reversed simply by pushing the INVERT STENCIL button.
This actually changes the status of the stencil and hence
swa ps the video displays between the
stencil on
and
stencil
off
areas.
NORMAL STENCIL
IN VERTED STENCIL
Stencil ON region brighter. Stencil regions swapped.
Old stencil OFF regions are now ON.
There are three basic image planes w h ich can be displayed in
the stencil
O n and Off
regions. These a re
live analog, live digital
and
field store.
The
live analog
video is the video input to the
Analog Path of the CVI. This is
not modified
by the CVI at all.
The
live d igital
video is the digitised video input to the D igital
Path. This may be colourized by the CVI. The
field store
is the
store in which all painting, freezing, zooming, etc. take place.
The field store can be used in a number of ways to give different
appearances. For example, live digital video can continually
update the field store to give effects such as pixelation o r live
mirrors; or the field store may .be filled, wiped or painted with
colour to create a background. See Section
1

Conceptual Model
for a full description of these three pla nes.
The name in each box gives an ind ication of what sort of
display resul ts on the screen. For example, if you select the box
called Paint, the displ a y will show the
field store
for both stencil
O f f
and stencil On. Updating o f the fie ld store b y the i ncoming
video is disabled. Hence
Paint
gives an ideal setup of the CVI for
painting or modifying images in the field store, w i thout having to
worry about your pa in ting bei n g destroyed by incoming updating
vi deo.
