The invention relates to a method for detecting a rolling shutter effect in images of an environmental region () of a motor vehicle () captured by an image sensor of at least one camera () of the motor vehicle () comprising a plurality of sensor lines (), including the following steps: a) determining a first position (P) on a sensor plane () of the image sensor corresponding to a feature () when capturing a first image and identifying a second position (P) on the sensor plane () corresponding to the feature () when capturing a second image, b) determining a motion vector (v) characterizing a displacement of the feature () on the sensor plane () between the first position (P) and the second position (P), c) determining a vertical span (&#x394;y) of the motion vector (v) characterizing a number of sensor lines () at least partially covered by the motion vector (v), d) detecting the rolling shutter effect based on the vertical span (&#x394;y). I addition, the invention relates to a computing device (), a driver assistance system () as well as a motor vehicle ().

The invention relates to a method for motion estimation between two images of an environmental region () of a motor vehicle () captured by a camera () of the motor vehicle (), 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 () for each first blocks (B) and its respective search region; d) determining an averaged cost surface () for one of the at least two first blocks (B) based on the cost surfaces (); 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 (), a driver assistance system () as well as a motor vehicle ().
