Abstract

The invention relates to a method for operating a rearview camera system (2) of a motor vehicle (1), in which a sequence of images (15) of an environmental region (9) behind the motor vehicle (1) is provided by means of an image capturing device (3) of the rearview camera system (2) and the sequence of the images (15) is displayed on a display (10), wherein a headlight flasher (14) of a vehicle (13) located in the environmental region (9) is detected by the rearview camera system (2) and due to the detection of the headlight flasher (14), a warning signal (17) separate from the images (15) is generated, by which the detected headlight flasher (14) is signaled to the driver of the motor vehicle (1).

Claims

1. A method for operating a rearview camera system of a motor vehicle, comprising:

providing, by an image capturing device of the rearview camera system, a sequence of images of an environmental region behind the motor vehicle;

displaying the sequence of the images on a display;

detecting, by the rearview camera system, a headlight flasher of a vehicle located in the environmental region; and

based on the detection of the headlight flasher, generating a warning signal by which the detected headlight flasher is signaled to the driver of the motor vehicle.

2. The method according to claim 1, wherein the motor vehicle is formed free of exterior mirrors and/or free of an interior mirror and the rear view camera system is formed as a digital mirror.

3. The method according to claim 1, wherein the headlight flasher is detected by the rearview camera system based on the images.

4. The method according to claim 1, wherein saturated pixels of the images are detected by the rearview camera system, and the detection of the headlight flasher is effected based on the saturated pixels.

5. The method according to claim 4, further comprising:

determining a saturation level of the saturated pixels; and

adjusting an intensity of the warning signal depending on the determined saturation level.

6. The method according to claim 1, wherein the warning signal is output by means of an output device separate from the display.

7. The method according to claim 6, wherein the warning signal is output by an illumination device separate from the display.

8. The method according to claim 1, wherein the warning signal is output by the display.

9. The method according to claim 8, wherein the warning signal is output in at least a partial region of the display that is backlit by a background illumination device of the display.

10. The method according to claim 1, wherein a position of a headlight flasher is determined in the images based on a position of the saturated pixels, by the rearview camera system.

11. The method according to claim 10, wherein the partial region of the display is determined depending on the position of the headlight flasher in the images.

12. A rearview camera system for a motor vehicle, wherein the rearview camera system is adapted to perform a method as claimed in claim 1.

13. A motor vehicle with a rearview camera system according to claim 12.
