1. A driver assistance system for a vehicle, said driver assistance system comprising:

  • an imager disposed at a vehicle equipped with said driver assistance system and viewing one of (i) forward of the equipped vehicle through a windshield of the equipped vehicle and (ii) rearward of the equipped vehicle;

    said imager having a field of view exterior the equipped vehicle and operable to capture color video images;

    said imager comprising (i) a lens, (ii) a spectral filter and (iii) a CMOS photosensor array of photosensor elements;

    a control comprising an image processor;

    wherein said control is operable to process captured video images for at least a first application and a second application, and wherein said first application is selected from the group consisting of (i) headlamp control, (ii) vehicle detection, (iii) rain sensing, (iv) lane departure warning, (v) ambient light sensing, (vi) collision avoidance, (vii) driving separation indication, (viii) backup assist and (ix) object detection;

    wherein said second application is another application selected from the group consisting of (i) headlamp control, (ii) vehicle detection, (iii) rain sensing, (iv) lane departure warning, (v) ambient light sensing, (vi) collision avoidance, (vii) driving separation indication, (viii) backup assist and (ix) object detection;

    wherein said control is operable to adjust a parameter of said imager;

    a display disposed in the equipped vehicle and viewable by a driver of the equipped vehicle; and

    wherein said control is operable to provide color management for display of captured color video images by said display;

    wherein said imager communicates an image signal to said display via a communication link, and wherein a display microcontroller affects the image signal in response to at least one user input, and wherein said control monitors the image signal on said communication link and adjusts a function of said imager in response to a detection of the affected image signal, and wherein said display microcontroller affects the image signal by disabling a video termination at said display.
