Abstract
A device includes a camera, which captures images of moving objects, lighting units, and a controller. The camera captures recordings of the moving objects in series during transportation on the conveyor, so that a first recording of the object in a first position and a second recording of the object in a second position are obtained. The first and second positions of the object differ by the movement of the conveyor by a corresponding offset. The illumination units are composed of a dark-field illumination unit and a bright-field illumination unit, which are controlled synchronously with the camera by the controller such that the first recording generates a first contrast by a first specific control of the dark-field illumination unit and bright-field illumination unit, and in that the second recording generates a second contrast by a second specific activation of the dark-field illumination unit and bright-field illumination unit.
