The Advanced Tab:
The Advanced Control tab (see Figure 26) contains additional controls that can help tune a TrackVIEW system for an
excellent performance of the auto-tracking functions.
•
Minimum Move
setting defines the number of horizontal cells that are required to be identified as movement. These
cells correspond to the motion mask cells which are 84 cells wide. The suggested value is 2.
•
Noise Filter
determines the performance of noise reduction. The recommended setting for the Noise Filter is 3.
Note:
The Noise Filter interacts with the Contrast control on the Room Set-up tab. As the noise level is increased, the
Contrast must be decreased. Also, lower values increase response while higher values decrease response time.
•
Minimum Target Height
defines the minimum height that can be identified as a target. This is dependent on the
distance the reference camera is away from the presenter. In a small room, the presenter may be 15 cells tall and in a
large room only 7 cells tall. Set the Minimum Target Height slightly higher than the height of the target or presenter.
The heights of the cells in the motion mask are 56-NTSC and 68-PAL.
•
Minimum Target Width
is the same type of control as the Target Height. This parameter defines the minimum width of
a subject that can be defined as a target. The width of the cells in the motion mask is 84.
•
Active Target Width
defines the number of tracking blocks in width required to continue to be recognized as a target.
The minimum Active Target Width will be always equal to or larger that the Minimum Target Width.
•
Tracking Duration
is the time in seconds that the target acquisition is maintained after movement stops. A lower value
will allow for quicker acquisition and a larger value will maintain acquisition longer. Suggested value is 4.
•
Tracking Positions
is the number of tracking cells in the field of view. Max is 84. Reducing the value will group the
cells reducing the number of camera movements. This reduces jitter when a subject stops moving. The Green meter
line will show the relative area of tracking as the Tracking Position parameter is reduced. The Red area indicates the
area outside the active tracking area. Maximize the Green meter length when setting this control. Set this parameter to
42 to start with any set-up.
•
Video System Indicator
shows the user which video format is being used - NTSC or PAL (see Figure 27).
Important Note: This parameter can be changed but hardware is required to change a NTSC unit into a PAL unit and
vice-versa. Order the unit required to operate in the country in which it is to be operated.
•
Back-up/Restore
allows a configuration to be saved and later restored in the case the system is “tinkered” with, is
partially disassembled or cameras moved. There are also some factory defaults built-in in cases where too many
parameters have been tweaked excessively and the system is not acting properly.
