4. A video conference system according to claim 1, wherein said display means is disposed at a selected one of said stations and separately displays an image obtained from the selected one station and images obtained from others of said stations.

5. A video conference system according to claim 1 or 4, wherein said station selecting means includes a pointing device for selecting the window on the screen of said display means.

6. A video conference system arranged to conduct a video conference among multiple interconnected stations having cameras by communicating at least images and sounds among the stations, comprising:

(a) display means for displaying images respectively obtained from said stations on individual screens;

(b) station selecting means for selecting one station from among said stations mode selecting means for selecting a system operating mode from among a first mode in which moving images respectively transmitted from said stations are displayed by said display means in a time-division manner, a second mode in which only an image transmitted from a station in which speaking is occurring is displayed as a moving image, while images transmitted from the others of said stations are respectively displayed by said display means as still images, and a third mode in which only an image transmitted from a station selected by said station selecting means is displayed by said display means as a moving image.

7. A video conference system according to claim 6, further comprising control means for executing operating control of a camera to obtain an image.

8. A video conference system according to claim 7, wherein when the third mode is selected by said mode selecting means, a camera disposed in a station other than a station in which said display means is disposed is controllable by said control means.

9. A video conference system according to claim 7, wherein when the first or second mode is selected by said mode selecting means, a camera disposed in a station in which said display means is disposed is controllable by said control means.

10. A control device for a plurality of image input devices, comprising:

(a) display means for displaying moving images respectively obtained from said image input devices on individual windows on a screen of said display means;

(b) selecting means for selecting one image input device from among said image input devices by selecting one window from said windows on the screen of said display means; and

(c) control means for controlling the image input device selected by said selecting means.

11. A control device according to claim 10, wherein said display means displays identification of the selected image input device.

12. A control device according to claim 10, wherein said control means includes a control window displayed on the screen of said display means.

13. A control device according to claim 10, wherein said selecting means includes a pointing device for selecting the window on the screen of said display means.

14. A control device for a plurality of image input devices, comprising:

(a) display means for displaying moving images respectively obtained from said image input devices on individual screens;

(b) selecting means for selecting one image input device from among said image input devices; and

(c) mode selecting means for selecting a device operating mode from among a first mode in which moving images respectively transmitted from said image input devices are displayed by said display means in a time-division manner, a second mode in which an image transmitted from a particular image input device is displayed by said display means as a moving image, while images transmitted from others of said image input devices are respectively displayed by said display means as still images, and a third mode in which an image transmitted from an image input device selected by said selecting means is displayed as a moving image.

15. A control device according to claim 14, further comprising control means for executing operating control of the image input devices to obtain the images.

16. A control device for a plurality of image input devices, comprising:

(a) display means for displaying moving images respectively obtained from said image input devices on individual screens;

(b) selecting means for selecting one image input device from among said image input devices; and

(c) mode selecting means for selecting as a device operating mode one mode from a first mode in which moving images respectively transmitted from the plurality of image input devices are displayed by said display means in a time-division manner and a second mode in which an image transmitted from an image input device selected by said selecting means is displayed as a moving image, while images corresponding to the others of said image input devices are respectively displayed as still images.

17. A control device according to claim 16, further comprising control means for executing operating control of the image input devices to obtain the images.

18. A video conference system arranged to be capable of conducting a video conference among multiple interconnected stations having cameras by communicating images among the stations, comprising:

(a) display means at one of said stations for displaying images obtained from said one station and others of said stations on windows on a screen of said display means, said windows corresponding individually with said stations; and

(b) control means for selectively controlling said display means to cause said windows to display images obtained from said one station and said other stations as moving images or still images.

19. A system according to claim 18, wherein said control means selectively controls said display means to cause one of said screens to display the image obtained from said one station as a moving image and to display the images obtained from said other stations as still images.

20. A system according to claim 18, wherein said control means selectively controls said display means to cause one of said screens to display an image obtained from a station other than said one station as a moving image and to display the images obtained from said one station as a still image.

21. A system according to claim 18, wherein said display means further provides a display of a control window for said control means.

22. A system according to claim 18 further communicating sound among said stations, said control means being operably responsive to sound issuing from a station to cause said display means to display the image obtained from said station as a moving image.
