An apparatus (), in particular a code reader, for the taking of undistorted images of a surface of objects () moved on a conveying device () is set forth, wherein the apparatus () has a geometry detection sensor () which is made for the detection of the geometry of the objects () with reference to spacing data and/or to the remission behavior of the objects () as well as a line sensor (), in particular a line camera, which can scan the objects () linewise for the generation of image data of the surface in a linear reading window () which forms an angle with the conveying direction. In this connection, a control () is provided which is made to generate, on the basis of geometrical data of the geometry detection sensor (), a respective spacing profile of the surface over the reading window () from the perspective of the line sensor () and to generate an associated zoom factor and/or a taking frequency for the line sensor () from each spacing profile; to set the line sensor () to the associated zoom factor and/or to the taking frequency for the respective line of the objects () to be scanned; and to compose the image data thus taken linewise in an undistorted manner to form a uniformly resolved total image of the surface.
