Switchable format film projection system |
摘要 |
The present invention relates to film transport systems for motion picture projectors and, more particularly, to a film projector movement that is capable of transporting film prints having frames spanning a predetermined number of perforations per frame at a specified projection frame-rate and then automatically switching to another film format having frames spanning a different number of perforations per frame as well as a different projection frame-rate, based on the detection of an encoded trigger strip on the film which carries the format characteristics of the incoming film. A controller enables the system to automatically switch between a variety of different film formats and frame-rates, on the same projector and on the same platter of film, without substantially interrupting or delaying operation of the projector.
