Abstract

Provided is an audio visual environment control system capable of realizing optimal audio-visual environment illumination control in accordance with the illumination condition upon shooting of a display image. A data transmission device comprises: a data multiplexing portion for multiplexing the shooting illumination data indicating the illumination condition at the shooting of each scene of video data on the video data, and a transmitting portion for modulating and transmitting the video data on which the shooting illumination data is multiplexed. A data receiving apparatus which receives the data comprises: a data separating portion 22 for separating the shooting illumination data from the video data, a CPU 23 for controlling the illuminating light of an illuminating device 27 in accordance with the illumination data, and an illumination control data generating portion 24.

Claims

1. A data transmission device that transmits image data composed of one or more scenes, wherein the shooting illumination data of each of one or more illuminating devices used at the time of shooting of each of scenes of the image data is added to the image data and transmitted.

2. The data transmission device as defined in claim 1, wherein

the shooting illumination data is added to the image data scene by scene.

3. The data transmission device as defined in claim 1, wherein

the shooting illumination data is added to the image data shot by shot.

4. The data transmission device as defined in claim 1, wherein

the shooting illumination data is added to the image data frame by frame.

5. The data transmission device as defined in any one of claims 1 to 4, wherein

the shooting illumination data at least contains data indicating a lighting type of illumination used for shooting of each scene.

6. The data transmission device as defined in any one of claims 1 to 4, wherein

the shooting illumination data at least contains data indicating a property of illumination used for shooting of each scene.

7. The data transmission device as defined in any one of claims 1 to 4, wherein

the shooting illumination data at least contains data indicating a direction of light of illumination used for shooting of each scene.

8. The data transmission device as defined in any one of claims 1 to 4, wherein

the shooting illumination data at least contains data indicating intensity of light of illumination used for shooting of each scene.

9. The data transmission device as defined in any one of claims 1 to 4, wherein

the shooting illumination data at least contains data indicating a chromaticity of light of illumination used for shooting of each scene.

10. A data transmission device that transmits shooting illumination data of each of one or more illuminating devices used at the time of shooting of each of scenes comprising image data on the reception of a transmission request from outside, wherein the shooting illumination data is transmitted together with data indicating a timing of start of each of scenes comprising the image data.

11. The data transmission device as defined in claim 10, wherein

the shooting illumination data at least contains data indicating a lighting type of illumination used for shooting of each scene.

12. The data transmission device as defined in claim 10 or 11, wherein

the shooting illumination data at least contains data indicating a property of illumination used for shooting of each scene.

13. The data transmission device as defined in claim 10 or 11, wherein

the shooting illumination data at least contains data indicating a direction of light of illumination used for shooting of each scene.

14. The data transmission device as defined in claim 10 or 11, wherein

the shooting illumination data at least contains data indicating intensity of light of illumination used for shooting of each scene.

15. The data transmission device as defined in claim 10 or 11, wherein

the shooting illumination data at least contains data indicating a chromaticity of light of illumination used for shooting of each scene.

16. An audio-visual environment control device comprising:

a receiving portion that receives image data to be displayed on a display device and shooting illumination data of each of one or more illuminating devices used at the time of shooting of each of scenes comprising the image data; and

a control portion that controls illuminating light from an illuminating device arranged around the display device, based on the shooting illumination data.

17. The audio-visual environment control device as defined in claim 16, wherein

the control portion controls illuminating light from the illuminating device by switching illuminating light scene by scene in the image data.

18. The audio-visual environment control device as defined in claim 16 or 17, wherein

the control portion controls illuminating light from the illuminating device using also a characteristic quantity of the image data, in addition to the shooting illumination data.

19. The audio-visual environment control device as defined in claim 16 or 17, wherein

the shooting illumination data at least contains data indicating a lighting type of illumination used for shooting of each scene.

20. The audio-visual environment control device as defined in claim 16 or 17, wherein

the shooting illumination data at least contains data indicating a property of illumination used for shooting of each scene.

21. The audio-visual environment control device as defined in claim 16 or 17, wherein

the shooting illumination data at least contains data indicating a direction of light of illumination used for shooting of each scene.

22. The audio-visual environment control device as defined in claim 16 or 17, wherein

the shooting illumination data at least contains data indicating intensity of light of illumination used for shooting of each scene.

23. The audio-visual environment control device as defined in claim 16 or 17, wherein

the shooting illumination data at least contains data indicating a chromaticity of light of illumination used for shooting of each scene.

24. An audio-visual environment control system comprising the audio-visual environment control device as defined in claim 16 or 17, and an illuminating device that is controlled by the audio-visual environment control device in emission of audio-visual environment illuminating light.

25. A data transmission method for transmitting image data composed of one or more scenes, wherein shooting illumination data of each of one or more illuminating devices used at the time of shooting of each of scenes of the image data is added to the image data and transmitted.

26. A data transmission method for transmitting shooting illumination data of each of one or more illuminating devices used at the time of shooting of each of scenes comprising image data on the reception of a request from outside, wherein the shooting illumination data is transmitted together with data indicating a timing to start of each of scenes comprising the image data.

27. An audio-visual environment control method that receives image data to be displayed on a display device and shooting illumination data of each of one or more illuminating devices used at the time of shooting of each of scenes comprising the image data and controls illuminating light from an illuminating device disposed around the display device based on the shooting illumination data.
