Abstract
In a night vision arrangement for a motor vehicle in which a camera captures an infra-red image of the roadway in front of the vehicle, a video signal generated by the camera is processed by a signal processor so that the field of view of the image displayed by a display unit is selected in accordance with a control signal. The control signal is generated by a signal generator which is responsive to one or more parameters of the movement of the vehicle. The width of the field of view may be decreased with increasing speed. The axial direction of the field of view may be adjusted depending upon the nature of a turning movement of the vehicle.
