Abstract

An automatic programming and video camera control system is disclosed in which while the camera operator is operating the video camera system, the control signals generated by the operator are converted to a unique plurality of signals for recordation on a mass storage media, such as a video tape recorder. On playback of the mass storage medium, the recorded signals are reproduced, decoded and used to provide automatic control of the video camera system. A modified video tape recorder may be used in which, during playback of the programmed signals, the video images viewed by the video camera are recorded on the video track portion of the magnetic tape.

Claims

1. An automatic control system for a video camera, comprising:

an input circuit for generating control signals for operating at least one video camera;

a converter for converting said control signals to data signals suitable for recording on an audio track of a storage medium;

a recording and reproducing apparatus for recording and reproducing said data signals on said storage medium;

a decoder for decoding said reproduced data signals such that said recording/reproducing apparatus uses said data signals to directly control said at least one video camera;

wherein said recording and reproducing apparatus comprises a video tape recorder comprised of;

a recording and reproducing apparatus for recording said data signals and

for reproducing said data signals from said audio track while simultaneously recording a video signal from said at least one video camera on a video track of said video tape recorder.

2. The system of claim 1, wherein said recorded video signal corresponds to the images viewed by said video camera system while under control of said data signals recorded on said video tape recorder.

3. The system of claim 1, wherein said data signals comprise audio frequency representations of a plurality of control signals.

4. The system of claim 1, wherein said recorder for recording said data signals comprises an audio recording head.

5. A control system for automatically providing a plurality of control signals in which each signal serves to control a function of a video camera system capable of a plurality of different functions, said control system comprising:

an input circuit for generating a plurality of different control signals;

a converter for converting each of said plurality of different control signals to data signals;

a recorder for recording each of said data signals and for reproducing said recorded data signals while simultaneously recording video signals generated by said video camera system using said same recorder; and

a decoder for decoding each of said data signals reproduced by said recorder to generate said plurality of control signals for operating said plurality of different control functions of said video camera system.

12. The system of claim 5, further including a positioning device for positioning said video camera system in a predetermined configuration prior to beginning the automatic control of said video camera system.

6. The system of claim 6, wherein said recorder comprises a magnetic tape recorder.

7. The system of claim 6, wherein said converter converts said control signals to dual tone multifrequency signals.

8. The system of claim 6, wherein said recorder comprises a video tape recorder.

9. The system of claim 6, wherein said video tape recorder is comprised:

a recording and reproducing apparatus for recording said data signals and

for reproducing said data signals from said audio track while simultaneously recording a video signal from said at least one video camera on a video track of said video tape recorder.

10. The system of claim 9, wherein said recorded video signal corresponds to the images viewed by said video camera system while under control of said data signals recorded on said video tape recorder.

11. The system of claim 9, wherein the control of said video camera system and the recording of said video signal from said video camera occurs in real-time.

13. A camera control system comprising:

an input device for generating camera movement in a plurality of directions;

a converter connected to said input device for generating a data signal in response to signals received from said input device such that said data signal represents the movement of said input device;

a video tape recorder for recording said data signal on an audio track of a video tape such that said data signal is reproduced simultaneously while recording a video signal on a video track of said video tape recorder;

a decoder for decoding said data signal to a predetermined voltage level; and

a sensor for sensing said predetermined voltage level and controlling particular camera functions based upon said sensed predetermined voltage level.

14. The system of claim 13, wherein said mass storage medium is magnetic tape.

15. The system of claim 13, wherein said means for converting converts said control signals to dual tone multifrequency signals.

16. The system of claim 13, wherein said recorded video signal corresponds to the images viewed by said video camera system while under control of said control signals recorded on said video tape recorder.

17. The system of claim 16, wherein the control of said video camera system and the recording of said video signal from said video camera occurs in real-time.

18. A method for automatically controlling at least one video camera using a recorder, comprising the steps of:

generating camera control signals for controlling said at least one video camera;

converting said camera control signals to data signals for recording on a storage medium;

recording said data signals simultaneously with controlling said at least one video camera;

reproducing said data signals simultaneously with recording a video signal;

decoding said data signals; and

controlling said at least one video camera through said decoded data signals directly from said recorder to said at least one video camera.
