Claim 19:
20. A vehicular imaging system, said vehicular imaging system comprising:
a camera comprising a CMOS imaging sensor;
said imaging sensor comprising a photosensor array having a plurality of photosensor elements;
wherein said camera is disposed in a vehicle equipped with said vehicular imaging system, and wherein said camera is disposed behind a windshield of the equipped vehicle and views through a portion of the windshield;
wherein said camera views a scene forward of the equipped vehicle;
wherein the portion of the windshield comprises a portion cleaned by a windshield wiper of the equipped vehicle;
wherein said camera is operable to capture frames of image data at an image frame capture rate that is between 5 times per second and 120 times per second;
wherein image data captured by said camera is provided to a control, said control comprising an image processor;
wherein said control receives, via a communication bus of the equipped vehicle, at least one selected from the group consisting of (i) vehicle pitch information relating to pitch of the equipped vehicle, (ii) vehicle yaw information relating to yaw of the equipped vehicle and (iii) vehicle steering information relating to steering of the equipped vehicle;
wherein said vehicular imaging system automatically corrects for misalignment of said camera disposed behind the windshield of the equipped vehicle and viewing through the portion of the windshield;
wherein said vehicular imaging system automatically corrects for misalignment of said camera of up to +/−4 degrees from an aligned condition of said camera;
wherein the automatic correction for misalignment of said camera mounted at the equipped vehicle comprises image processing at said control of image data captured by said camera determining where converging road features of a road along which the equipped vehicle is traveling would converge; and
wherein image data captured by said camera is processed at said control for a lane departure warning system of the equipped vehicle and for at least one selected from the group consisting of (i) an automatic headlamp control system of the equipped vehicle, (ii) a collision avoidance system of the equipped vehicle and (iii) an adaptive front lighting system of the equipped vehicle.
