Abstract

A continuous motion picture system for operation in conjunction with a vehicle carrying passengers along a running path is disclosed. The system has screen boxes having a screen and a projector for displaying a still picture for a duration of a display period. The screen boxes are serially disposed at intervals of a given distance provided in place along the running path of the vehicle. The system also has a device for supplying picture signals of a sequence of fames, which depict motion when viewed sequentially, to the projectors of the screen boxes such that each of the projectors receives a respective one of the frames of the sequence of frames in correspondence with the serial disposition of the screen boxes. The system further has a sensor for sequentially triggering the screen boxes to individually display the respective one of the frames as a still picture for the display period in correspondence with the vehicle passing the screen boxes. Passengers can see the pictures as motion pictures for guidance or publicity when the vehicle is in motion. It is easy for the workers to change and it takes a short time to change from the present still pictures to the next still pictures.

Claims

1. A continuous motion picture system for operation in conjunction with a vehicle carrying passengers along a running path, comprising:

screen boxes serially disposed at intervals of a given distance along the running path;

said screen boxes each including a display means with a screen for displaying a still picture for a duration of a display period;

distribution means for supplying picture signals of a sequence of frames, which depict motion when viewed sequentially, to said display means of said screen boxes such that each of said display means receives a respective one of said frames of said sequence of frames in correspondence with the serial disposition of said screen boxes; and

means for sequentially triggering said screen boxes to individually display said respective one of said frames as a still picture for said display period in correspondence with the vehicle passing said screen boxes so as to reproduce said motion when said screen boxes are sequentially viewed by the passengers of the vehicle.

2. A continuous motion picture system according to claim 1, wherein each of said screen boxes comprises:

a screen box body defining an opening in a front thereof;

said screen being mounted in the opening and having a back side upon which said still picture is projected and a front side at which said still picture is viewed;

said display means being a projector mounted inside said screen box body to project said still picture on said back side of said screen; and

said projector including means for receiving said picture signals of said respective one of said frames from the distribution means for supplying picture signals and projecting said respective one of said frames onto the screen as said still picture.

3. A continuous motion picture system according to claim 2, wherein said screen includes a polarized light screen mounted at said back side thereof for receiving a projection of said respective one of said frames.

4. A continuous motion picture system according to claim 1, wherein said screen boxes are respectively disposed on or within vending machines.

5. A continuous motion picture system according to claim 1, wherein said display means is a liquid crystal projector having a blinkable back-light for projecting said still picture for said display period.

6. A continuous motion picture system according to claim 1, wherein said distribution means for supplying picture signals includes a digital video player and a digital signal distributor for distributing signals of said respective ones of said frames to respective ones of said screen boxes.

7. A motion picture system for operation in conjunction with a vehicle carrying passengers along a running path, comprising:

screen boxes serially disposed at intervals of a given distance along the running path;

said screen boxes each including a digital display means with a screen for displaying a still picture for a duration of a display period;

distribution means for supplying digital picture signals of a sequence of frames, which depict motion when viewed sequentially, to said digital display means of said screen boxes such that each of said digital display means receives a digital picture signal representing a respective one of said frames of said sequence of frames in correspondence with the serial disposition of said screen boxes; and

triggering means for sequentially triggering said screen boxes to individually display said respective one of said frames as a still picture for said display period in correspondence with the vehicle passing said screen boxes so as to reproduce said motion when said screen boxes are sequentially viewed by the passengers of the vehicle.

8. A motion picture system according to claim 7, wherein each of said display means is a digital image projector for projecting onto said screen and said digital image projector includes means for receiving said digital picture signals of said respective one of said frames from said distribution means.

9. A motion picture system according to claim 8, wherein said digital image projector is a liquid crystal projector having a blinkable back-light for projecting said still picture for said display period responsive to said triggering means.

10. A motion picture system according to claim 8, wherein said distribution means for supplying digital picture signals includes a digital video player and a digital signal distributor for distributing signals of said respective ones of said frames to respective ones of said screen boxes.

11. A motion picture system according to claim 10, wherein said digital signal distributor is a computer receiving said digital picture signals and distributing signals of said respective ones of said frames to respective ones of said screen boxes.

12. A motion picture system according to claim 7, wherein said distribution means for supplying digital picture signals includes a digital video player and a digital signal distributor for distributing signals of said respective ones of said frames to respective ones of said screen boxes.

13. A motion picture system according to claim 12, wherein said digital signal distributor is a computer receiving said digital picture signals and distributing signals of said respective ones of said frames to respective ones of said screen boxes.

14. A motion picture system according to claim 7, wherein said screen boxes are respectively disposed on or within vending machines.

15. A motion picture system for operation in conjunction with a vehicle carrying passengers along a running path, comprising:

displays for displaying digitally encoded images for a duration of a display period, said displays being serially disposed at intervals of a given distance along the running path;

a digital video player for supplying digital picture signals of a sequence of frames which depict motion when viewed sequentially;

distribution means for distributing said digital display signals to said displays such that each of said displays receives a digital picture signal representing a respective one of said frames of said sequence of frames in correspondence with the serial disposition of said displays; and

triggering means for sequentially triggering said displays to individually display said respective one of said frames as a still picture for said display period in correspondence with the vehicle passing said displays so as to reproduce said motion when said displays are sequentially viewed by the passengers of the vehicle.

16. A motion picture system according to claim 15, wherein said distribution means is a computer receiving said digital picture signals and distributing signals of said respective ones of said frames to respective ones of said screen boxes.

17. A motion picture system according to claim 15, wherein said distribution means is incorporated into said digital video player.
