10. The system for collecting image information of claim 7 , further comprising:

collecting means for collecting sound information of sound generated at at least one of the subject and surroundings thereof while the subject is shot by the shooting devices; and

extracting means, connected to the collecting means and the storage device, for extracting, from the image information stored in the storage device, image information acquired during particular time spans including times, at which an intensity of sound represented by the sound information has exceeded a predetermined level.

11. The system for collecting image information of claim 10 , wherein the storage device stores, together with the image information, time information representing a shooting time at which an image has been shot.

12. The system for collecting image information of claim 11 , wherein the storage device stores time information corresponding to the times at which the intensity of sound represented by the sound information has exceeded the predetermined level.

13. The system for collecting image information of claim 12 , wherein, on the basis of time information corresponding to the times at which the intensity of sound has exceeded the predetermined level, the extracting means extracts, from the storage device, the image information acquired during the particular time spans including the times.

14. A method for collecting image information of a subject using shooting devices and a storage device for storing the image information, comprising the steps of:

providing the subject with a transmission device for transmitting a radio signal representing a location of the subject;

shooting the subject using the shooting devices in such a manner that at least one of the shooting devices can shoot the subject to generate image information including images of the subject;

storing the image information in the storage device; and

extracting, from the image information stored in the storage device, image information including images representing at least the subject on the basis of the received location information of the subject.

15. The method for collecting image information of claim 14 , wherein the shooting devices are placed in mutually different positions around an area to be shot and substantially all of the area to be shot can be shot by combining shooting areas of the shooting devices.

16. The method for collecting image information of claim 15 , further comprising the step of synthesizing the extracted image information such that image information shot by the shooting devices whose shooting areas are adjacent to each other become successive in order of time.

17. The method for collecting image information of claim 14 , wherein sound information of sound generated at at least one of the subject and surroundings thereof is collected while the subject is shot by the shooting devices, and image information acquired during particular time spans including times, at which an intensity of sound represented by the sound information has exceeded a predetermined level, is extracted from the image information stored in the storage device.

18. The method for collecting image information of claim 17 , wherein the storage device stores, together with the image information, time information representing a shooting time at which an image has been shot.

19. The method for collecting image information of claim 18 , wherein the storage device stores time information corresponding to the times at which the intensity of sound represented by the sound information has exceeded the predetermined level.
