Note: The Image Acquisition Toolbox Preview window and the Preview window that is
built into the Image Acquisition Tool support the display of up to 16-bit image data. The
Preview window was designed to only show 8-bit data, but many cameras return 10-, 12-,
14-, or 16-bit data. The Preview window display supports these higher bit-depth cameras.
However, larger bit data is scaled to 8-bit for the purpose of displaying previewed data. If
you need the full resolution of the data, use the getsnapshot or getdata functions.
Stopping the Preview Video Stream
When you use the preview function to start previewing image data, the Video Preview
window displays a view of the live video stream coming from the device. To stop the
updating of the live video stream, call the stoppreview function.
This example creates a video input object and opens a Video Preview window. The
example then calls the stoppreview function on this video input object. The Video
Preview window stops updating the image displayed and stops updating the timestamp.
