Abstract

A technique for presenting display screens of a plurality terminals connected to a network on a multi-window screen of a display screen of a display device. A communication unit receives image data captured and then sent by each terminal having a screen capture function. A display control unit controls an image synthesizer to synthesize the captured image data into single screen multi-window format data. A multi-window screen is thus presented.

Claims

1. A display method of a projector connected to a plurality of terminals via a network to project image data transmitted from all of the plurality of terminals connected to the projector in a multi-window screen, comprising:

assigning one of a plurality of window areas to each of the image data transmitted from each of the terminals;

assigning, to each of the plurality of window areas, respective images which each have been converted in a display size of the corresponding image data transmitted from each of the terminals; and

after an image is inserted or erased, in the multi-window screen, displaying all the images in the multi-window screen without overlapping each other, the plurality of window areas are sized based on priority order for each terminal of the plurality of terminals;

when no priority order is set to all of the plurality of terminals and screen sizes of the plurality of terminals are the same, the plurality of window areas are automatically divided equivalently.

2. The display method of claim 1, wherein a specific window in the multi-window screen can be expanded by a predetermined operation of a remote controller to the projector.

3. The display method of claim 1, wherein the multi-window screen can be switched to a single window screen only for a specific window in the multi-window screen by a predetermined operation of a remote controller to the projector.

4. The display method of claim 3, wherein the single window screen can be returned to the multi-window screen by a predetermined operation of a remote controller to the projector.

5. The display method of claim 1, wherein a new window can be inserted into the multi-window screen by a predetermined operation of a remote controller to the projector.

6. The display method of claim 1, wherein a specific window in the multi-window screen can be erased by a predetermined operation of a remote controller to the projector.

7. The display method of claim 6, wherein the multi-window screen is reorganized into a plurality of windows according to the number of windows after erasing the specific window, and is displayed.

8. The display method of claim 6, wherein the multi-window screen after erasing the specific window is displayed, without reorganizing the screen.

17. The display method of claim 1, wherein:

the conversion of each display size of the images has been performed while maintaining an aspect ratio of the corresponding image data before the conversion.

9. A projector connected to a plurality of terminals via a network to project image data transmitted from all of the plurality of terminals connected to the projector in a multi-window screen, wherein:

one of a plurality of window areas is assigned to each of the image data transmitted from each of the terminals;

images which each have been converted in a display size of the corresponding image data transmitted from each of the terminals are assigned to the respective window areas;

after an image is inserted or erased, in the multi-window screen, all the images are displayed in the multi-window screen without overlapping each other, the plurality of window areas are sized based on priority order for each terminal of the plurality of terminals;

when no priority order is set to all of the plurality of terminals and screen sizes of the plurality of terminals are the same, the plurality of window areas are automatically divided equivalently.

10. The projector of claim 9, wherein a specific window in the multi-window screen can be expanded by a predetermined operation of a remote controller to the projector.

11. The projector of claim 9, wherein the multi-window screen can be switched to a single window screen only for a specific window in the multi-window screen by a predetermined operation of a remote controller to the projector.

12. The display method of claim 11, wherein the single window screen can be returned to the multi-window screen by a predetermined operation of a remote controller to the projector.

13. The projector of claim 9, wherein a new window can be inserted into the multi-window screen by a predetermined operation of a remote controller to the projector.

14. The projector of claim 9, wherein a specific window in the multi-window screen can be erased by a predetermined operation of a remote controller to the projector.

15. The projector of claim 14, wherein the multi-window screen is reorganized into a plurality of windows according to the number of windows after erasing the specific window, and is displayed.

16. The projector of claim 14, wherein the multi-window screen after erasing the specific window is displayed, without reorganizing the screen.

18. The projector of claim 9, wherein:

the conversion of each display size of the images has been performed while maintaining an aspect ratio of the corresponding image data before the conversion.

19. An image display apparatus connected to a plurality of terminals via a network to project image data transmitted from each of the terminals in a multi-window screen, wherein:

one of a plurality of window areas is assigned to each of the image data transmitted from each of the terminals;

images which each have been converted in a display size of the corresponding image data transmitted from each of the terminals are assigned to the respective window areas; and

after an image is inserted or erased, in the multi-window screen, all the images are displayed in the multi-window screen without overlapping each other, the plurality of window areas are sized based on priority order for each terminal of the plurality of terminals; and

when no priority order is set to all of the plurality of terminals and screen sizes of the plurality of terminals are the same, the plurality of window areas are automatically divided equivalently.

20. The image display apparatus of claim 19, wherein:

the conversion of each display size of the images is performed while maintaining an aspect ratio of the corresponding image data before the conversion.
