1. A vehicular vision system, the vehicular vision system comprising:
a forward viewing camera disposed at an in-cabin side of a windshield of a vehicle equipped with the vehicular vision system, the forward viewing camera viewing through the windshield forward of the vehicle, the forward viewing camera capturing image data;
a driver viewing camera disposed in the vehicle and viewing at least the eyes of a driver of the vehicle;
a control comprising circuitry and associated software;
wherein the circuitry of the control comprises an image processor;
wherein the windshield comprises a locally dimmable windshield that is operable, responsive to the control, to locally darken windshield regions of the windshield to reduce transmission of visible light through the windshield at the locally darkened windshield regions of the windshield;
wherein image data captured by the forward viewing camera is processed to determined (i) a light source ahead of the vehicle, (ii) an intensity of the determined light source and (iii) a position of the determined light source relative to the vehicle;
wherein image data captured by the driver viewing camera is processed to determine a gaze direction of the eyes of the driver;
wherein the control, responsive to processing of image data captured by the forward viewing camera and responsive to processing of image data captured by the driver viewing camera, determines a forward view path between the eyes of the driver and the position of the determined light source and determines a location where the determined forward view path intersects the windshield; and
wherein the control, responsive to the intensity of the determined light source being greater than a threshold level, controls the windshield to locally darken a windshield region that includes the location where the determined forward view path intersects the windshield.
