Abstract
To record an image of the mouth area (2) of a bottle (1), a luminous surface (3) is arranged below the mouth area to be recorded. The luminous surface (3) is lighted by means of a lighting device (4) and the image of the lighted mouth area (2) is sent to a camera by a mirror arrangement (5, 6, 11). With the luminous surface, it is possible to image the mouth area in transmitted light, which yields improved detection of defects and soiling in the mouth area and thus permits easier evaluation of the image recorded by the camera.
