Adaptive light passage region control

A method of adapting light passage for a vehicle window, the method comprising:

• sensing a light source external to the vehicle window, the light source operable to affect viewing the external environment;
• capturing video of a forward perspective of the vehicle window;
• defining a portion of an adaptive light passage region of the vehicle window relative to a gaze direction of a vehicle occupant;
• determining a portion of the video aligned with the gaze direction of the vehicle occupant;
• and
• displaying the portion of the video aligned with the gaze direction of the vehicle occupant in the portion of the adaptive light passage region of the vehicle window when the light source exceeds an intensity threshold while one or more other portions of the adaptive light passage region of the vehicle window remain transparent, wherein the portion of the adaptive light passage region is transparent when the light source does not exceed the intensity threshold.

A vehicle control unit comprising:

• a communication interface to service communication with a vehicle network;
• a processor communicably coupled to the communication interface;
• and
• memory communicably coupled to the processor and storing:
• a light source detection module including instructions that, when executed by the processor, cause the processor to:
• sense a light source external to a vehicle window;
• capture video of a forward perspective of the vehicle window;
• determine an intensity of the light source;
• and
• compare the intensity with an intensity threshold;
• and
• a window opacity module including instructions that, when executed by the processor, cause the processor to, when the intensity of the light source exceeds the intensity threshold:
• define a portion of an adaptive light passage region of the vehicle window relative to a gaze direction of a vehicle occupant for producing an area parameter of a plurality of window opacity parameters;
• determine a portion of the video aligned with the gaze direction of the vehicle occupant;
• and
• display the portion of the video aligned with the gaze direction of the vehicle occupant in the portion of the adaptive light passage region of the vehicle window when the light source exceeds the intensity threshold while one or more other portions of the adaptive light passage region of the vehicle window remain transparent, wherein the portion of the adaptive light passage region is transparent when the light source does not exceed the intensity threshold.
