1. A visibility-enhanced system (1) for a motor vehicle assistance system to warn a driver of a dangerous situation, comprising:

  • a first sensor device (2) comprising a camera mounted on the rear-view device of the motor vehicle, adapted to record at least one image;

    -a second sensor device (3) adapted to generate at least one position characteristic of at least one object (6) located within a critical range (7) of the first sensor device (2); and

    an image processing device (4) adapted to;

    receiving a first input signal from the first sensor device (2) comprising the at least one image and a second input signal from the second sensor device (3) comprising the at least one position characteristic of the at least one object (6) within the critical range (7), andprocessing the at least one image to generate a processed image (8) by,(i) changing a contrast of a portion of the image showing the at least one object (6) located within the critical range (7), wherein changing the contrast of the portion of the image showing the at least one object (6) located within the critical range (7) comprises increasing the contrast, and(ii) changing the contrast of the portion of the image not showing the at least one object (6) within the critical range (7), wherein changing the contrast of the portion of the image not showing the at least one object (6) within the critical range (7) comprises decreasing the contrast,wherein the critical range is a predetermined distance from the vehicle,wherein the determination of whether the object is in the critical range can be performed at the second sensor device or at the image processing device, andwherein the first sensor device (2) and the second sensor device (3) substantially face a driving scene behind a driving direction of the motor vehicle.
