ABSTRACT OF THE DISCLOSURE A process for reading a chain of code characters which is arranged annularly on a transparent bottle in the bottom area of the same, by photographing at least the bottom area of the bottle through the bottle neck by means of a camera and simultaneously illuminating the bottom area of the bottle from below. With a zero relative speed of rotation between camera, bottle and illumination source, a snapshot of the bottom area of the bottle with the complete code character chain is taken from the inside of the bottle with the camera and is stored as an image for the later decoding of the code character chain. The code-reading process is a very rapid process, because the fraction of a second in which the bottle is in a line with the camera and the illumination source is adequate for reading the code. The evaluation of the image of the code character chain which is photographed occurs using a histogram technique by comparison with a stored annular pattern which is divided into sectors.
