Fine-Tuning Autoframing Behavior
The Autoframing feature can be tuned to your specific installation. This includes adjusting the tracking
area, speed, sensitivity, and responsiveness.
How It Works: Digital Pan/Tilt/Zoom
Optical Zoom and Electronic Zoom are the names of two Autoframing adjustments, in addition to being
simple terms for the two ways that a camera can zoom. This section talks about how zooming works.
The lenses in a camera control how much of the room can be in the shot – the image area. Zooming in
optically makes the image area smaller by moving the lenses. Zooming in digitally makes the image area
smaller by using the pixels from a smaller portion of the image sensor. Either way, the effect is the same:
When the image area is smaller, everything in the shot looks bigger.
Digital pan and tilt work when the camera is zoomed in. If some image area is available outside the shot,
the camera can pan and tilt by moving the image area to use pixels outside the current shot. If the current
shot uses all the pixels, there's no room to pan or tilt.
Autoframing uses digital pan, tilt, and zoom operations to keep the subject in the frame. As the camera
zooms in, more pan and tilt is available because the image area is a smaller part of the total field of view.
Because Autoframing pans and tilts to center the source of motion, the image is almost always zoomed
in at least slightly.
The unmasked portion in each frame of the diagram represents the zoomed image while the camera
pans from the Mars globe to Dr. Sagan.
