1. An automatic vehicle exterior light control, comprising:
- an image sensor; and
a controller in communication with said image sensor, said controller configured to generate at least one parameter selected from the group comprising sensitivity, image window size, field of view, image window center, rate of change of exterior light brightness, image analysis, exterior light automatic operation inhibit, image sensor aim, exterior light control transition delay, operator indicator, and variable spectral filter;
wherein, said at least one parameter is a function of a vehicle speed signal.

4. A method of generating an exterior light control signal in a system comprising an image sensor generating a plurality of pixel levels from a scene being imaged and a controller to generate at least one exterior light control signal, the method comprising the steps of:
-
receiving pixel levels from the image sensor;
determining at least one vehicle speed criterion; and
analyzing at least one image as a function of said at least one speed criterion. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)
