Abstract: The present invention relates to processing a material. The material lies on a carrier and is cut by irradiation with a laser beam, or an object of the material is catapulted from the carrier to a collection device by means of the laser beam. An image of the material on the carrier is generated. The image is evaluated automatically in order to identify structures in it. A region of the image is automatically selected on the basis of the identified structures. The selected region is then used for automatically cutting the material and/or catapulting the object, or serves as a working region in which the material is cut or from which the object is catapulted. Parallel sections through the material may in particular be employed.
