Abstract

An image display system includes: a plurality of image supply devices each having an image display section, and an image transmission section adapted to generate a supply image and to externally transmit the supply image; and an image display device capable of dividing a common screen area into one or more screen areas, and of displaying the supply image supplied from each of the image supply devices in the one or more screen areas, wherein each of the image supply devices displays a common screen area operating image to operate a display state of the common screen area in the image display section, and supplies a display image of the image display section to the image display device as the supply image, and the image display device changes the display state of the common screen area in accordance with an operation in each of the image supply devices.

Claims

1. An image display system having a common screen area allowing a plurality of users to view a common image, comprising:

a plurality of image supply devices each having an image display section, and an image transmission section adapted to generate a supply image using an image displayed in the image display section and to externally transmit the supply image; and

an image display device capable of dividing the common screen area into one or more screen areas, and of displaying the supply image supplied from each of the plurality of image supply devices in the one or more screen areas,

wherein each of the image supply devices displays a common screen area operating image to operate a display state of the common screen area in the image display section, and supplies a display image of the image display section to the image display device as the supply image, and

the image display device changes the display state of the common screen area in accordance with an operation in each of the image supply devices via the common screen area operating image.

2. The image display system according to claim 1, wherein

the common screen area operating image includes a layout image having divisional layout frames showing a configuration of one or more screen areas in the common screen area,

the divisional layout frames can be changed by an operation on the common screen area operating image, and

the image display device performs display after changing a configuration of the one or more screen areas in the common screen area in accordance with the change of the divisional layout frames.

3. The image display system according to claim 2, wherein

the image display device generates new divisional layout frames in response to an operation of dragging a boundary between the divisional layout frames into an area in the layout frame on the common screen area operating image, and

the image display device deletes the divisional layout frames in response to an operation of dragging the boundary existing between the divisional layout frames out of the layout image on the common screen area operating image.

4. The image display system according to claim 2, wherein

the common screen area operating image has an identification image list area adapted to display a list of identification images for identifying the supply images supplied from the image supply devices, and

the image display device displays the supply image identified by the identification image selected in the identification image list area on the common screen area operating image.

5. The image display system according to claim 4, wherein

the image display device displays the supply image identified by the identification image in the screen area in the common screen area corresponding to the divisional layout frame in which the identification image is dragged and dropped when the user drags and drops the identification image selected from the identification image list area in the divisional layout frame.

6. The image display system according to claim 4, wherein

the image supply device generates new divisional layout frames for the supply image identified by the identification image in an area corresponding to a position inside the divisional layout frame and shifted toward a circumferential end when the identification image selected from the identification image list area is dragged and dropped into the position, and

the image display device displays the supply image identified by the identification image in the screen area corresponding to the new divisional layout frame of the common screen area.

7. The image display system according to claim 1, wherein

the common screen area operating image includes a changeover switch image adapted to switch a division number in the common screen area, and

the image display device divides the common screen area into the division number designated with the changeover switch image.

8. The image display system according to claim 1, wherein

the image supply device supplies the display image of the image display section except the common screen operating image.

9. The image display system according to claim 1, wherein

the image supply device supplies a part of the display image of the image display section.

10. An image display method in an image display system capable of displaying supply images respectively supplied from a plurality of image supply devices on a common screen area divided into one or more screen areas via an image display device, the method comprising:

(a) displaying common screen area operating image to operate a display state of the common screen area in each of image display sections of the image supply devices;

(b) generating the supply image using an image displayed in the image display section in each of the image supply devices, and supplying the image display device with the supply image; and

(c) changing the display state of the common screen area in the image display device in accordance with an operation in each of the image supply devices via the common screen area operating image.

11. An image display device capable of displaying supply images from a plurality of image supply devices each having an image display section and an image transmission section adapted to generate a supply image using an image displayed in the image display section and to externally transmit the supply image on a common screen area allowing a plurality of users to view a common image, the image display device:

changes a display state of the common screen area in response to an operation via a common screen area operating image displayed in each of the image display sections of the respective image supply devices; and

divides the common screen area into one or more screen areas to display a display image of the image display section.
