Fig.1
shows a profile move for Pan, Tilt., Zoom and Focus. In the move illustrated, pan has
further to move than tilt, therefore pan moves at a faster speed than tilt so that it stops at
position 2 at the same instant as tilt.
The
default setting is that zoom also moves in the same time but the zoom start and stop times
can be adjusted. The Zoom Start can be adjusted to be before or after the main move. The
Zoom End can also be adjusted to be before or after the main move. Focus moves during the
centre portion of the move so that objects of interest are not de-focused during the start or
end of the move.
The
Profile of each move is stored with each position.
Fig.2
illustrates that each move
TO
a pre-
set position will take the time associated with that end position. Understanding this enables
efficient use of the same start position.
