9.6.3.3 Masking menu
Dynamic masking allows the creation of up to a
maximum of 24 masks so as to obtain the masking of
certain areas defined by the user.
Masks are defined in space and take account of the
horizontal, vertical and zoom depth position when
making the settings.
ULISSE COMPACT THERMAL automatically maintains
the position and dimension of the masking, based on
the displayed area.
It is possible to simultaneously display up to 8 masks.
If the device is used at maximum speed, video signal
updating times become critical and it is necessary to
create masks larger than the object so that it remains
masked for longer during the passage and therefore
cannot be seen.
j
To ensure full functionality, the tilt position
of the masks must always be between -70
and +70 degrees; in addition , the size of
the mask must be double the size of the
object to be masked (both height-wise and
width-wise).
From the Masking menu it is possible to set the
following parameters:
01. Mask Colour: Allows you to choose the colour
of the masks.
02. Edit Masks: Allows access to the Edit Masks
submenu and set the dynamic masking
parameters.

The default name and position of the
zones of the pan & tilt refer to the four
cardinal points. The NORTH position can
be modified by means of the Offset Pan
parameter in the movement menu ("9.6.4
Movement menu", page 33).
