Abstract: A method for operating a driver assistance system of a motor vehicle is provided. A first image sequence of a first rear environmental region of the motor vehicle is provided by a first camera system of an electronic rearview mirror and the first image sequence is displayed on a display device of the electronic rearview mirror disposed in an interior of the motor vehicle. Furthermore, a second image sequence of a second environmental region of the motor vehicle, which overlaps with the first environmental region at least in certain areas, is provided by a second camera system of an environmental capturing device. The electronic rearview mirror is then checked for presence of a malfunction by a computing device of the driver assistance system and the second image sequence is displayed on the display device of the electronic rearview mirror when the malfunction is present.

Abstract: The invention relates to a method for motion estimation between two images of an environmental region (9) of a motor vehicle (1) captured by a camera (4) of the motor vehicle (1), wherein the following steps are performed: a) determining at least two image areas of a first image as at least two first blocks (B) in the first image, b) for each first block (B), defining a respective search region in a second image for searching the respective search region in the second image for a second block (B) corresponding to the respective first block (B); c) determining a cost surface (18) for each first blocks (B) and its respective search region; d) determining an averaged cost surface (19) for one of the at least two first blocks (B) based on the cost surfaces (18); d) identifying a motion vector (v) for the one of the first blocks (B) describing a motion of a location of the first block (B) in the first image and the corresponding second block (B) in the second image. The invention also relates to a computing device (3), a driver assistance system (2) as well as a motor vehicle (1).

Abstract: The invention relates to a method for detecting a rolling shutter effect in images of an environmental region (9) of a motor vehicle (1) captured by an image sensor of at least one camera (4) of the motor vehicle (1) comprising a plurality of sensor lines (15), including the following steps: a) determining a first position (P1) on a sensor plane (13) of the image sensor corresponding to a feature (14) when capturing a first image and identifying a second position (P2) on the sensor plane (13) corresponding to the feature (14) when capturing a second image, b) determining a motion vector (v) characterizing a displacement of the feature (14) on the sensor plane (13) between the first position (P1) and the second position (P2), c) determining a vertical span (Δy) of the motion vector (v) characterizing a number of sensor lines (15) at least partially covered by the motion vector (v), d) detecting the rolling shutter effect based on the vertical span (Δy). I addition, the invention relates to a computing device (3), a driver assistance system (2) as well as a motor vehicle (1).
