ABSTRACT:
A method of reading positional information on photographic film in which items of positional information are read during the feeding of an elongated photographic film, the positional information items being provided in a predetermined sequence and in correspondence with a plurality of image frames recorded on the film in the longitudinal direction thereof. The number of feed pulses that corresponds to the direction and the distance which the photographic film is fed is calculated. On the basis of the calculated number of feed pulses and of the corresponding item of positional information, the number of feed pulses corresponding to a predetermined reference position is calculated. On the basis of the calculated number of feed pulses corresponding to the predetermined reference position, the position at which each of the following items of positional information have been read is checked. Based on the number of feed pulses, it is therefore possible to check whether or not the read positional information items are correct.
