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 each of the terminals in a multi-window screen, comprising:

assigning a window area sequentially to each of the image data transmitted from each of the terminals;

assigning, to the window area, an image which has been converted in size while maintaining an aspect ratio of the image data transmitted from each of the terminals; and

displaying all images at the same time in a multi-window screen without overlapping each other.

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.

9. A projector 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:

a window area is assigned sequentially to each of the image data transmitted from each of the terminals;

an image which has been converted in size while maintaining an aspect ratio of the image data transmitted from each of the terminals is assigned to the window area; and

all images are displayed at the same time in a multi-window screen without overlapping each other.

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.
