A system for imposing a filter between a vehicle driver's eyes and a
source of light including at least one detector facing inward into a
compartment in the vehicle toward a likely position of the head of the
vehicle driver and arranged to obtain images of the eyes of the driver
and a processor coupled to the detector(s) and arranged to determine the
location of the driver's eyes based on analysis of the images obtained by
the detector(s) and to obtain information about objects exterior of the
vehicle providing sources of light from the images obtained by the
detector(s) based on reflections off of the driver's eyes, i.e., the
position of such objects. A filter, such as a pixelated screen, is
imposed between the sources of light and the driver's eyes based on the
location of the driver's eyes and the information about the exterior
objects providing the sources of light.
