Enhanced vision for driving
First Claim
1. A system for imposing a filter between a vehicle driver'"'"'s eyes and a source of light, comprising:
- 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;
processor means coupled to said at least one detector and arranged to determine the location of the driver'"'"'s eyes based on analysis of the images obtained by said at least one detector and to obtain information about objects exterior of the vehicle providing sources of light from the images obtained by said at least one detector based on reflections off of the driver'"'"'s eyes; and
filter means coupled to said processor means for imposing a filter between the sources of light and the driver'"'"'s eyes based on the location of the driver'"'"'s eyes as determined by said processor means and the information about the exterior objects providing the sources of light obtained by said processor means.

Abstract
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.

16. A method for imposing a filter between a vehicle driver'"'"'s eyes and a source of light, comprising the steps of:
-
arranging at least one detector to face inward into a compartment in the vehicle toward a likely position of the head of the vehicle driver;
obtaining images of the eyes of the driver from the at least one detector;
determining the location of the driver'"'"'s eyes based on analysis of the images obtained by the at least one detector;
obtaining information about objects exterior of the vehicle providing sources of light from the images obtained by the at least one detector based on reflections off of the driver'"'"'s eyes; and
imposing a filter between the sources of light and the driver'"'"'s eyes based on the determined location of the driver'"'"'s eyes and the obtained information about the exterior objects providing the sources of lights. - View Dependent Claims (17, 18, 19, 20)
