AGC feedback circuitry optimizes the gain, or level of NVIS intensification. A sudden increase in radiance reduces or shuts down intensification so that the phosphor image dims and loses contrast.

AGC also increases intensification when ambient irradiation is low.

Automatic gain control. When the light falling onto an imaging device reduces to a certain level, there is insufficient light to create a full level video signal. AGC acts to increase the amount of amplification in these conditions to bring the signal up to the required level. As well as amplifying the video signal, additional noise can be introduced, and the signal to noise ratio reduced. The result is frequently a very much degraded signal and poor picture on the monitor.
