1. An active light source operating system for a vehicle comprising:
- at least one light source generating an initial illumination beam;
a selective attenuation filter forming an emitted illumination beam having an associated light attenuation matrix, with a plurality of pixels, in response to said initial illumination beam;
a sensor detecting at least one object and generating an object detection signal; and
a controller coupled to said selective attenuation filter and said sensor and attenuating at least one of said plurality of pixels in said light attenuation matrix in response to said object detection signal.

Abstract
An active light source operating system (10,11) for a vehicle (14) includes a light source (50) that generates an initial illumination beam (54). A selective attenuation filter (27,52) forms an emitted illumination beam (56), with an associated light attenuation matrix (32,33), in response to the initial illumination beam (54). A sensor (31) detects an object and generates an object detection signal. A controller (35) is coupled to the selective attenuation filter (27,52) and said sensor (31). The controller (35) attenuates a pixel (104) in the light attenuation matrix (32,33) in response to the object detection signal.
