ABSTRACT:
Moving-map display for bringing about the precise position control of the area of the film to be displayed transversely in "x" (longitude) by purely electronic and static means and longitudinally in y (latitude) by using the lateral perforations of the film. To this end it has a computer which processes, as a function of the longitude and heading, the line-by-line scanning data of the useful area to be displayed and, as a function of the latitude, the positioning data in "y" by cyclically carrying out a lateral scan along the perforations where there are coded inscriptions in such a way as to process a signal corresponding to the variation in "y" to be cancelled out by controlling a servo-motor.
