Abstract

An image display device for displaying an image based on an image signal input from a plurality of image supply devices via a network includes a storage section storing connection information used for the image supply device being connected to the image display device via the network, an encoding section encoding the connection information to generate a connection information code which can be recognized by the image supply device, a display section displaying the connection information code and the image based on the image signal input from the image supply device, and an image control section dividing an image display area of the display section into a plurality of divisional areas, and displaying the image based on the image signal input from respective one of the image supply devices in each of the divisional areas.

Claims

1. An image display device for displaying an image based on an image signal input from a plurality of image supply devices via a network, comprising:

a storage section storing connection information used for the image supply device being connected to the image display device via the network;

an encoding section encoding the connection information to generate a connection information code which can be recognized by the image supply device;

a display section displaying the connection information code and the image based on the image signal input from the image supply device; and

an image control section dividing an image display area of the display section into a plurality of divisional areas, and displaying the image based on the image signal input from respective one of the image supply devices in each of the divisional areas.

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

the encoding section adds area information used for specifying each of the divisional areas to the connection information, and encodes the connection information added with the area information to generate a plurality of connection information codes respectively corresponding to the divisional areas, and

the image control section displays the connection information codes in the respective divisional areas to allow the image supply devices to recognize the connection information and the area information, and then obtains the area information recognized by the image supply device, and further displays the image based on the image signal input from the image supply device in the divisional area indicated by the area information.

3. The image display device according to claim 1, wherein

the different connection information is assigned to each of the divisional areas,

the encoding section encodes the connection information assigned to each of the divisional areas to generate a plurality of connection information codes, and

the image control section displays the connection information codes in the respective divisional areas to allow the image supply devices to recognize the connection information, and then obtains the connection information recognized by the image supply device, and further displays the image based on the image signal input from the image supply device in the divisional area corresponding to the connection information.

4. The image display device according to claim 1, wherein

the encoding section generates the connection information code common to the divisional areas, and

the image control section displays the connection information code in the display section to allow the image supply devices to recognize the connection information, and then assigns either one of the plurality of divisional areas to the image supply device connected via the network, and displays the image based on the image signal input from the image supply device in the divisional area assigned to the image supply device.

5. The image display device according to claim 1, further comprising:

a switching section switching between a state in which a plurality of images based on the image signals input from the plurality of image supply devices are displayed in the image display area of the display section and a state in which the image based on the image signal input from either one of the plurality of image supply devices is displayed in substantially the whole area of the image display area.

6. An image display system comprising a plurality of image supply devices each outputting an image signal, and an image display device displaying an image based on the image signal input from each of the plurality of image supply devices via a network, wherein

the image display device includes

a storage section storing connection information used for the image supply device being connected to the image display device via the network,

an encoding section encoding the connection information to generate a connection information code which can be recognized by the image supply device,

a display section displaying the connection information code and the image based on the image signal input from the image supply device, and

an image control section dividing an image display area of the display section into a plurality of divisional areas, and displaying the image based on the image signal input from respective one of the image supply devices in each of the divisional areas,

the image supply device includes,

a connection information recognition section analyzing the connection information code displayed by the display section to recognize the connection information, and

a network connection section, based on the connection information recognized by the connection information recognition section, establishing a network connection with the image display device.

7. A network connecting method of an image display system including an image supply device outputting an image signal, and an image display device having a display section, and displaying an image based on the image signal input from the image supply device via a network in an image display area of the display section, comprising:

a first step in which the image display device encodes connection information for connecting the image display device itself via the network to generate a connection information code which can be recognized by the image supply device;

a second step in which the image display device displays the connection information code in the image display area;

a third step in which the image supply device analyzes the connection information code displayed in the image display area to recognize the connection information;

a fourth step in which the image supply device performs the network connection with the image display device based on the recognized connection information;

a fifth step in which the image display device coordinates one of divisional areas obtained by dividing the image display area with the image supply device connected via the network;

a sixth step in which the image display device displays the image based on the image signal input from the image supply device in the area coordinated with the image supply device.
