Abstract
A cinematographic film system which employs film having a motion picture sequence recorded thereon with at least one intervening frame between recorded frames. A second motion picture sequence is recorded on uniformly spaced intervening frames. The film is projected using a film transport operating to advance the film in multiple frame steps equal to the spacing of the frames in said motion picture sequences. The film transport is adjustable to permit, on signal, a single one-frame advance and thus shift the film from one to the other of said motion picture sequences. In a vehicle simulator, the film and projector coact to impart considerable flexibility to film-based visual display systems.
Claims5
A visual simulation system for vehicle trainers comprising, in combination:
- a student station having simulated controls appropriate to the vehicle for providing output signals representative of the actuation of said simulated controls;
- a cine film strip carrying a first motion picture sequence recorded on selected frames uniformly spaced from each other by at least one intermediate frame and a second motion picture sequence recorded on intermediate frames spaced from one another by the same number of frames as said selected frames;
- a cine projector for displaying said cine film strip including film transport means adjustable to advance said cine film in increments of a single or multiple frames at a time;
- and
- means responsive to selected ones of said output signals for selectively adjusting the film transport means to change momentarily between single and multiple frame film advance during operation of the projector so that a selection can be made as to which of the motion picture sequences is displayed.
A visual simulation system for vehicle trainers comprising, in combination:
- a student station having simulated controls appropriate to the vehicle;
- a cine film strip carrying a first motion picture sequence recorded on selected frames uniformly spaced from each other by at least one intermediate frame and a second motion picture sequence recorded on intermediate frames spaced from one another by the same number of frames as said selected frames;
- a visual display including a cine projector for presenting to an occupant of the student station a cinematographic visual representation of an environment appropriate to the vehicle, said projector including film transport means adjustable to advance said cine film in single or multiple frame increments and normally advancing the film in uniform multiple frame increments;
- computational means responsive to input signals provided by said simulated controls for providing output signals representative of particular manipulations of said controls by a trainee;
- and
- means responsive to said output signals to adjust said transport means momentarily to effect an odd number of single-frame film advance increments while the film transport is operating and thereafter to return said transport means to its normal, multiple-frame advance mode so that a selection can be made as to which of the motion picture sequences is displayed.
