A method for recognizing defects on a homogeneous surface of an object during a movement of the object is provided, wherein an image of the homogeneous surface is recorded and the image is evaluated as to whether it has defects. In this respect, the image is recorded by an event-based image sensor that detects events of a changing intensity with a plurality of pixel elements; the recording takes place over a time interval within which the homogeneous surface moves on over at least some pixel elements of the image sensor; the events are corrected in accordance with a time that has elapsed since a reference point in time and the movement that has taken place during the elapsed time; and the corrected events are collected in an image that is then evaluated with respect to the defects.
