VEHICULAR IMAGE SENSING SYSTEM
First Claim
1. A vehicle headlamp control, comprising:
- an imaging sensor that senses light in spatially separated regions of a field of view forward of a vehicle; and
a control circuit that is responsive to said imaging sensor in order to determine if individual regions of the field of view include light levels having a particular intensity level in order to identify light sources of interest and provide a control output to said vehicle that is a function of the identification of light sources of interest.

Abstract
A vehicle headlamp control method and apparatus includes providing an imaging sensor that senses light in spatially separated regions of a field of view forward of the vehicle. Light levels sensed in individual regions of the field of view are evaluated in order to identify light sources of interest, such as oncoming headlights and leading taillights. The vehicle'"'"'s headlights are controlled in response to identifying such particular light sources or absence of such light sources. Spectral signatures of light sources may be examined in order to determine if the spectral signature matches that of particular light sources such as the spectral signatures of headlights or taillights. Sensed light levels may also be evaluated for their spatial distribution in order to identify light sources of interest.
