Abstract

A display system displays a received image on a display device based on image information transmitted from at least one image supply device via a network. An image generating unit generates a segmented image segmented into plural individual areas, the segmented image contains an individual connection image representing connection information for the image supply device to connect to the display device in an area correlated to one individual area of the plural individual areas. A determining unit determines whether connection is permitted or not based on the connection request information. When connection to the image supply device is permitted by the determining unit, the image generating unit generates the segmented image containing the received image based on the image information from the image supply device in the individual area.

Claims

1. A display device configured to display a received image based on image information transmitted from at least one image supply device, the display device comprising:

a display unit configured to display a segmented image that includes plural individual display areas, at least one of the plural individual display areas being configured to display an individual connection image, the individual connection image including;

a connection information for the at least one image supply device to connect to the display device, and

an area information identifying a corresponding individual display area of the segmented image; and

a receiving unit configured to receive the image information and a connection request information from the at least one image supply device.

2. The display device according to claim 1, wherein the individual connection image contains a coded connection information and a coded area information identifying the individual display area.

3. The display device according to claim 1, wherein the display unit displays the received image according to the image information from the at least one image supply device which sent the connection request information in the individual display area based on information identifying the individual display area contained in the connection request information generated based on the connection information and the area information by the at least one image supply device.

4. The display device according to claim 1, further comprising a determining unit configured to determine whether a connection is permitted based on the connection request information.

5. The display device according to claim 4, further comprising an updating unit configured to update an area management data representing whether the individual display area is in use, wherein the determining unit permits the connection to the at least one image supply device which sent the connection request information when the individual display area indicated by the connection request information is not in use and refuses the connection to the at least one image supply device when the individual display area is in use based on the connection request information and the area management data.

6. The display device according to claim 1, wherein the segmented image contains a plurality of the individual connection images correlated to different individual display areas, respectively, and the display unit displays an image showing a desired individual connection image of the plurality of the individual connection images in a different display format from those of the other individual connection images as the segmented image.

7. The display device according to claim 1, wherein the image information contains a resolution information representing a resolution of the image and a contents information representing a contents of the image, and the display unit displays the received image adjusted to a resolution adapted to a resolution of the individual display area based on the resolution information and the contents information in the individual display area.

8. The display device according to claim 1, wherein the individual connection image comprises a barcode that encodes the coded connection information and the coded area information.

9. A display system comprising:

a display device configured to display a received image based on an image information transmitted from at least one image supply device, the display device including;

a display unit configured to display a segmented image that includes plural individual display areas, at least one of the plural individual display areas being configured to display an individual connection image, the individual connection image including;

a connection information for the at least one image supply device to connect to the display device, and

an area information identifying the corresponding individual display area of the segmented image;

a receiving unit configured to receive the image information and a connection request information from the at least one image supply device; and

the at least one image supply device configured to transmit the image information, the image supply device including;

an imaging unit configured to take an image of an area including the individual display area in the segmented image and to generate imaging information,

an information generating unit configured to generate a connection request information representing a connection request based on the connection information contained in the imaging information, and

a transmitting unit configured to transmit the connection request information and the image information.

10. A display method, comprising:

displaying a segmented image that includes plural individual display areas by a display device, at least one of the plural individual display areas being configured to display an individual connection image, the individual connection image including;

a connection information for at least one image supply device to connect to the display device, and

an area information identifying a corresponding individual display area of the segmented image;

imaging an area using the at least one image supply device, the area including an individual display area of the segmented image;

generating an image information using the at least one image supply device;

generating a connection request information representing a connection request toward the display device using the at least one image supply device based on the connection information contained in the imaging information;

transmitting the connection request information using the at least one image supply device to the display device;

receiving the connection request information at the display device and establishing a connection to the at least one image supply device which sent the connection request information; and

receiving the image information and displaying the segmented image containing a received image using the display device based on the image information, the received image being displayed in one of the plural individual display areas identified by the area information.
