1. A park-aid system for a vehicle, said park-aid system comprising:

  • a forward-viewing color video camera disposed at a vehicle equipped with said park-aid system;

    wherein said forward-viewing color video camera is disposed at a front portion of the equipped vehicle and has a field of view exterior of and at least forward of the equipped vehicle;

    said forward-viewing color video camera comprising a lens and a two-dimensional array of photosensing elements arranged in rows of photosensing elements and columns of photosensing elements;

    wherein said forward-viewing color video camera is part of a multi-camera vision system of the equipped vehicle, said multi-camera vision system comprising at least three other color video cameras;

    wherein each of said three other color video cameras has a respective field of view exterior of the equipped vehicle;

    wherein a first one of said three other color video cameras is mounted at a driver-side of the equipped vehicle and a second one of said three other color video cameras is mounted at a passenger-side of the equipped vehicle and a third one of said three other color video cameras comprises a rear backup camera mounted at a rear portion of the equipped vehicle;

    wherein the first one of said three other color video cameras has a field of view at the driver-side of the equipped vehicle and the second one of said three other color video cameras has a field of view at the passenger-side of the equipped vehicle;

    wherein the field of view of the first one of said three other color video cameras overlaps the field of view of said rear backup camera;

    wherein the field of view of the second one of said three other color video cameras overlaps the field of view of said rear backup camera;

    at least one ultrasonic sensor operable to sense sensor data;

    a video display screen viewable by a driver of the equipped vehicle when the driver is normally operating the equipped vehicle;

    wherein said video display screen comprises a multi-pixel display screen that is backlit using at least one white light emitting light-emitting diode;

    wherein said at least one white light emitting light-emitting diode is electrically operable to deliver a luminous efficiency of at least 1 lumen per watt;

    wherein, during a parking maneuver of the equipped vehicle, images derived, at least in part, from image data captured by at least said forward-viewing camera are displayed by said video display screen to assist the driver in operating the equipped vehicle;

    wherein, during the parking maneuver of the equipped vehicle and responsive to sensing by said ultrasonic sensor, objects present exterior the equipped vehicle are detected;

    wherein at least one indication is provided to the driver of the equipped vehicle during the parking maneuver;

    wherein at least one of (a) said at least one indication comprises an indication provided, at least in part, responsive to detection by said ultrasonic sensor of at least one object external of the equipped vehicle and (b) said at least one indication comprises an indication provided, at least in part, responsive to image processing by an image processor of image data captured by at least said forward-viewing camera;

    wherein said lens of said forward-viewing camera utilizes wide-angle optics, and wherein distortion of images derived, at least in part, from image data captured using said wide-angle optics is electronically corrected; and

    wherein the field of view of said forward-viewing color video camera encompasses a ground area to the front of the equipped vehicle having a width at least an entire front fender width of the equipped vehicle.
