In a film scanner with an automatic focusing device in which the film images are shown line by line by means of an objective on at least one line sensor, with a still film the adjusting range of the objective is passed through according to a predefined program. The then developing video signals are evaluated for their high frequency component. The objective is adjusted to the maximum of the high frequency component.
