Abstract

A multi display system including a main display apparatus is provided. The main display apparatus includes: an input unit configured to receive an image signal; a processor configured to process the image signal to generate an image frame to be displayed on a multi display system including the main display apparatus and at least one sub display apparatus and to adjust a resolution of the image frame based on the number and resolutions of the at least one sub display apparatuses; an output unit configured to transmit the image frame having the adjusted resolution to the at least one sub display apparatus; and a display unit configured to display an area of the image frame having the adjusted resolution and corresponding to the main display apparatus.

First claim

What is claimed is:

1 . A main display apparatus of a multi display system comprising:
communication circuitry configured to receive an image signal; a processor configured to process the image signal to generate an image frame to be displayed on the multi display system, the multi display system comprising the main display apparatus and at least one sub display apparatus, the processor further configured to adjust a resolution of the image frame based on the number and resolution of the at least one sub apparatus, and to control the communication circuitry to transmit the image frame having the adjusted resolution to the at least one sub display apparatus; and a display configured to display an area of the image frame having the adjusted resolution and corresponding to the main display apparatus.

2 . The main display apparatus of claim 1 , wherein the processor is configured to reduce noise of the image frame having the adjusted resolution.

3 . The main display apparatus of claim 2 , wherein the processor further comprises a decoder configured to decode the image signal,
wherein the processor is configured to generate the image frame based on the decoded image signal.

4 . The main display apparatus of claim 2 , wherein the processor is configured to generate a graphic user interface (GUI) image to be displayed on the main display apparatus and the at least one sub display apparatus, and to combine the GUI image with the image frame.

5 . The main display apparatus of claim 4 , wherein the communication circuitry is configured to transmit the image frame combined with the GUI image to the at least one sub display apparatus.

6 . A sub display apparatus of a multi display system comprising:
communication circuitry configured to receive an image frame from a main display apparatus of the multi display system, the image frame having a resolution adjusted by the main display apparatus to be displayed on a multi display system, the multi display system comprising the main display apparatus and at least one sub display apparatus, the communication circuitry further configured to transmit the image frame having the adjusted resolution to another sub display apparatus of the multi display system; and a display configured to display an area of the image frame having the adjusted resolution and corresponding to the sub display apparatus.

7 . The sub display apparatus of claim 6 , further comprising:
image quality processing circuitry configured to adjust an image quality based on a characteristic of the display unit.

8 . A multi display system comprising:
a main display apparatus and a plurality of sub display apparatuses, the main display apparatus configured to process an image signal to generate an image frame to be displayed on the multi display system, to adjust a resolution of the image frame based on the number and resolutions of respective sub display apparatuses of the plurality of sub display apparatuses of the multi display system, to transmit the image frame having the adjusted resolution to at least one of the sub display apparatuses, and to display an area of the image frame having the adjusted resolution; and wherein the plurality of sub display apparatuses are configured to receive the image frame having the resolution adjusted by the main display apparatus and to display an area of the received image frame corresponding to the sub display apparatus.

9 . A method of displaying an image on a main display apparatus of a multi display system, comprising:
processing an image signal to generate an image frame to be displayed on a multi display system comprising the main display apparatus and at least one sub display apparatus; adjusting a resolution of the image frame based on the number and resolutions of respective ones of the at least one sub display apparatuses; transmitting the image frame having the adjusted resolution to the at least one sub display apparatus; and displaying an area of the image frame having the adjusted resolution and corresponding to the main display apparatus on the main display apparatus.

10 . The method of claim 9 , further comprising:
reducing noise of the image frame having the adjusted resolution.

11 . The method of claim 9 , wherein the generating of the image frame comprises:
generating a GUI image to be displayed on the main display apparatus and the at least one sub display apparatus; and combining the GUI image with the image frame.

12 . The method of claim 11 , wherein the transmitting of the image frame to the at least one sub display apparatus comprises transmitting the image frame combined with the GUI image to the at least one sub display apparatus, and the displaying of the area of the image frame on the main display apparatus comprises displaying the area of the image frame being combined with the GUI image and corresponding to the main display apparatus on a screen.

13 . A method of displaying an image on a sub display apparatus of a multi display system, comprising:
receiving an image frame having a resolution adjusted by a main display apparatus of the multi display system to enable the image frame to be displayed on the multi display system, the multi display system comprising the main display apparatus and at least one sub display apparatus; transmitting the image frame having the adjusted resolution to another sub display apparatus of the multi display system; and displaying an area of the image frame having the adjusted resolution and corresponding to the sub display apparatus on a display corresponding sub display apparatus.

14 . The method of claim 13 , further comprising:
adjusting an image quality based on a characteristic of a display of the sub display apparatus.
