1. A vision system of a vehicle, said vision system comprising:

  • a camera module configured to be disposed at and behind a vehicle windshield;

    wherein said camera module comprises a first camera and a second camera;

    wherein, with said camera module disposed at and behind the vehicle windshield, said first camera views through the vehicle windshield and forward of the vehicle and said second camera views through the vehicle windshield and forward of the vehicle;

    wherein said first camera comprises a first lens and a first imager, and wherein said first camera has a wide angle field of view through the vehicle windshield greater than 100 degrees;

    wherein said first camera is operable to capture image data;

    a control comprising a first processor for image processing image data captured by said first camera;

    wherein said second camera comprises a second lens and a second imager, and wherein said second camera has a narrow angle field of view through the vehicle windshield less than 40 degrees;

    wherein said second camera is operable to capture color image data;

    wherein said control comprises a second processor for video processing color image data captured by said second camera;

    wherein an output of said second processor comprises color video images derived from video processing of color image data captured by said second camera;

    wherein the output of said second processor is provided to a display;

    wherein said display displays at a display screen color video images output by said second processor, and wherein said display screen is disposed in the vehicle and is viewable by a driver of the vehicle;

    wherein image data captured by said first camera is processed via said first processor to detect objects present in the field of view of said first camera, and wherein image data captured by said first camera is not video processed for display of video images derived from image data captured by said first camera;

    wherein, responsive to determination of a nighttime driving condition, said vision system operates in nighttime mode, and wherein, responsive to determination of a daytime driving condition, said vision system operates in daytime mode, and wherein, with said vision system operating in daytime mode, said vision system, via processing by said first processor of image data captured by said first camera, and via processing by said second processor of color image data captured by said second camera, is operable to (i) detect objects present in the wide angle field of view of said first camera and (ii) detect objects present in the narrow angle field of view of said second camera; and

    wherein said vision system, responsive to ambient light, switches from nighttime mode, where color video images derived from color image data captured by said second camera are displayed at said display screen, to daytime mode, where color image data captured by said second camera is processed by said second processor to detect objects present in the narrow angle field of view of said second camera.
