Scaling down
—The scaling down circuitry also controls the active
acquisition region. The NI 1411 can scale down a frame by reducing
the number of pixels per line, the number of lines per frame, or both.
For active pixel selection, the NI 1411 can select every pixel, every
other pixel, every fourth pixel, or every eighth pixel. For active line
selection, the NI 1411 can select every line, every other line, every
fourth line, or every eighth line. You can use the scaling down circuitry
in conjunction with the region-of-interest circuitry.
