1. A device for monitoring surroundings of a vehicle, comprising: at least one camera; an image processing unit operatively configured to receive an output of the camera; an image display unit operatively configured to receive an output of the image processing unit; and at least one sensor that captures driving dynamic data and is coupled to the image processing unit; wherein the image processing unit is operatively configured to perform image grading for reducing noise components in images recorded by the camera, said image grading averaging a number of images recorded by the camera; wherein the number of images averaged during the image grading is variable; and wherein the image processing unit performs the image grading by carrying out an adaptive adaptation of the number of images as a function of at least one driving dynamic parameter of the vehicle that is determined based on the driving dynamic data captured by the at least one sensor.
