Abstract
To photograph the mouth region of a bottle, a light-emitting surface is arranged below the mouth region to be photographed. The light-emitting surface is illuminated by means of an illuminating device and the image of the illuminated mouth region is directed to a camera by a mirror arrangement (5,6,11). The light-emitting surface makes it possible to image the mouth region in transmitted light, facilitating detection of defects and soiling in the mouth region from the interpretation of the image recorded by the camera.
