Abstract
A night vision system that allows a video camera to continue to be operational after a power control signal, such as a headlamp switch, to the camera has been temporarily interrupted. The system is designed to avoid a camera calibration or equalization process every time the power control signal from the camera or a display unit is disrupted.
