4 . The driver assisting system as claimed in claim 1 further comprising wherein the processing means ( 14 ) is further adapted to determine the color of the warning light ( 22 ).

5 . The driver assisting system as claimed in claim 4 , wherein the processing means ( 14 ) is further adapted to verify that the determined color corresponds to at least one pre-defined color.

6 . The driver assisting system as claimed in claim 1 further comprising wherein the processing means ( 14 ) is further adapted to verify that the warning light ( 22 ) belongs to a stationary vehicle ( 21 ) or a moving vehicle ( 21 ).

7 . The driver assisting system as claimed in claim 1 further comprising wherein the processing means ( 14 ) is further adapted to verify that the warning light ( 22 ) has a pre-defined pattern.

8 . The driver assisting system as claimed in claim 1 further comprising wherein the processing means ( 14 ) is further adapted to verify that the warning light ( 22 ) has a pre-defined positional relationship to a second motor vehicle ( 21 ).

9 . The driver assisting system as claimed in claim 1 further comprising wherein the processing means is further adapted to classify the warning light ( 22 ) as belonging to at least one category of an emergency second vehicle ( 21 ).

10 . The driver assisting system as claimed in claim 1 further comprising wherein the processing means ( 14 ) is further adapted to determine a speed or a distance of a second vehicle ( 21 ) generating the warning light ( 22 ).

11 . The driver assisting system as claimed in claim 10 , wherein the processing means ( 14 ) is further adapted to control the driver assisting means ( 18 ) depending on at least one of the determined speed and distance of the second vehicle ( 21 ) generating the warning light ( 22 ).

12 . The driver assisting system as claimed in claim 1 further comprising wherein the processing means ( 14 ) is further adapted to control the driver assisting means ( 18 ) depending on geographical position information.

13 . The driver assisting system as claimed in claim 1 further comprising wherein the processing means ( 14 ) is further adapted to obtain the geographical position information from a vehicle receiver ( 15 ) of at least one of a navigation satellite system, a cellphone network, and a wireless network, and from image processing of the acquired images.

14 . The driver assisting system as claimed in claim 1 wherein the imaging means ( 11 ) comprises a rear view camera ( 12 ).

15 . A driver assisting method for a motor vehicle, comprising acquiring images from a surrounding of the motor vehicle, applying image processing to the acquired images, and providing driver assistance information to the driver of the vehicle based on a result of the image processing, detecting, from the image processing, a periodically blinking warning light, and informing or alerting the driver in case a periodically blinking warning light is detected.

16 . The driver assisting method as claimed in claim 15 , further comprising wherein the processing means ( 14 ) further determining the blinking frequency of the warning light ( 22 ) and determining if the blinking frequency corresponds to at least one pre-defined blinking frequency.

17 . The driver assisting method as claimed in claim 15 further comprising wherein the processing means ( 14 ) further determining the color of the warning light ( 22 ) and determining that the determined color corresponds to at least one predefined color.

18 . The driver assisting method as claimed in claim 15 further comprising the processing means ( 14 ) further verifying that the warning light ( 22 ) belongs to a stationary second vehicle ( 21 ) or a moving second vehicle ( 21 ).

19 . The driver assisting method as claimed in claim 15 further comprising wherein the processing means ( 14 ) further verifying that the warning light ( 22 ) has a pre-defined pattern.

20 . The driver assisting method as claimed in claim 5 further comprising wherein the processing means ( 14 ) is further verifying that the warning light ( 22 ) has a pre-defined positional relationship to a second motor vehicle ( 21 ).

21 . The driver assisting method as claimed in claim 15 further comprising wherein the processing means further classifying the warning light ( 22 ) as belonging to at least one category of an emergency second vehicle ( 21 ).

22 . The driver assisting method as claimed in claim 15 further comprising wherein the processing means ( 14 ) further determining a speed or a distance of a second vehicle ( 21 ) generating the warning light ( 22 ).

23 . The driver assisting method as claimed in claim 15 further comprising wherein the processing means ( 14 ) further controlling the driver assisting means ( 18 ) depending on geographical position information.
