Zusammenfassung:A method is used for analyzing scenes. The scene or objects in the scene and an optical sensor perform a relative movement and the scene information obtained is evaluated. Visual information of the scene is detected by the individual pixels of the optical sensor and pixel co-ordinates of established variations in intensity are determined. A temporization of the established variations in intensity is determined and a local accumulation of the variations in intensity is determined by statistical methods. The local accumulations are evaluated in terms of the number and/or position thereof by statistical methods and data area clearing methods. The determined values are used as parameters of a detected scene region. A parameter is compared with a pre-determined parameter considered characteristic of an object, and when the pre-determined comparison criteria are fulfilled, the evaluated local amassment associated with the respective scene region is seen as an image of the object.
