A system for visibility enhancement for a motor vehicle assistant system for warning the driver of hazardous situations comprising: first sensor means comprising a camera installed in a rear view equipment of the motor vehicle, and adapted to record at least one image; second sensor means adapted to generate at least one position profile of at least one object located by object detection to be within a critical range of the first sensor means, where the critical range extends up to a predetermined distance from the motor vehicle, and where the first and second means are arranged to essentially face a driving scheme behind the driving direction of the motor vehicle; and image processing means adapted to: receive a first input signal from the first sensor means containing the at least one image and a second input signal from the second sensor means containing the at least one position profile of the at least one object located within the critical range, and manipulate the at least one image to generate a manipulated image by (i) altering the contrast of that part of the image that shows the at least one object located within the critical range, wherein altering the contrast of that part of the image that shows the at least one object located within the critical range comprises increasing the contrast of the entire area of the image that shows the object but not the area around the object, and (ii) altering the contrast of that part of the image that does not show the at least one object located within the critical range, wherein altering the contrast of that part of the image that does not show the at least one object located within the critical range comprises decreasing the contrast of the entire area of the image that does not show the object. first sensor means comprising a camera installed in a rear view equipment of the motor vehicle, and adapted to record at least one image; second sensor means adapted to generate at least one position profile of at least one object located by object detection to be within a critical range of the first sensor means, where the critical range extends up to a predetermined distance from the motor vehicle, and where the first and second means are arranged to essentially face a driving scheme behind the driving direction of the motor vehicle; and image processing means adapted to: receive a first input signal from the first sensor means containing the at least one image and a second input signal from the second sensor means containing the at least one position profile of the at least one object located within the critical range, and manipulate the at least one image to generate a manipulated image by (i) altering the contrast of that part of the image that shows the at least one object located within the critical range, wherein altering the contrast of that part of the image that shows the at least one object located within the critical range comprises increasing the contrast of the entire area of the image that shows the object but not the area around the object, and (ii) altering the contrast of that part of the image that does not show the at least one object located within the critical range, wherein altering the contrast of that part of the image that does not show the at least one object located within the critical range comprises decreasing the contrast of the entire area of the image that does not show the object.
