Abstract

A display system displaying an image on a basis of an image signal received from an image signal source, including: a key signal generator generating a key signal according to a user'"'"'s manipulation; a configuration controller providing a GUI for controlling a display state of the image, and outputting a control order corresponding to the user'"'"'s manipulation on the GUI, and detecting whether a user'"'"'s access to the GUI is limited; and a display controller controlling the display state of the image on a basis of the control order received from the configuration controller, recognizing the key signal as a first control signal to implement a pre-set control function according to the recognized first control signal if the key signal is input from a key signal input part while determining that the user'"'"'s access to the GUI is not limited, and recognizing the key signal as a second control signal to control the display state of the image according to the recognized second control signal if the key signal is input from the key signal input part while determining that the user'"'"'s access to the GUI is limited.

Claims

1. A display system displaying an image on a basis of an image signal received from an image signal source, comprising:

a key signal generator generating a key signal according to a user'"'"'s manipulation;

a configuration controller providing a graphical user interface (GUI) for controlling a display state of the image, and outputting a control order corresponding to the user'"'"'s manipulation on the GUI, and detecting whether a user'"'"'s access to the GUI is limited; and

a display controller controlling the display state of the image on a basis of the control order received from the configuration controller, recognizing the input key signal as a first control signal to implement a pre-set control function according to the recognized first control signal if the key signal is inputted from a key signal input part while determining through the configuration controller that the user'"'"'s access to the GUI is not limited, and recognizing the input key signal as a second control signal to control the display state of the image according to the recognized second control signal if the key signal is inputted from the key signal input part while determining through the configuration controller that the user'"'"'s access to the GUI is limited.

2. The display system according to claim 1, wherein the configuration controller comprises a display state configuration program installed in the image signal source and being driven based on an operating system of the image signal source.

3. The display system according to claim 2, further comprising an interface capable of interchangeably communicating with the image signal source, wherein the display state configuration program outputs information on whether the user'"'"'s access to the GUI is limited to the display controller through an interface part.

4. The display system according to claim 3, wherein the display state configuration program recognizes that the user'"'"'s access to the GUI is not limited when a size of the image provided by a program activated on the operating system of the image signal source is smaller than a size of a desktop screen provided by the operating system of the image signal source, and recognizes that the user'"'"'s access to the GUI is limited when the size of the image provided by the program activated the operating system of the computer is bigger than the size of the image of the desktop screen provided by the operating system of the computer.

5. The display system according to claim 4, wherein the display state configuration program reads data on the size of the image provided by the activated program and the size of the desktop screen provided by the operating system from a registry of the image signal source.

6. The display system according to claim 5, wherein the display controller implements an automatic screen adjustment function when the key signal is recognized as the second control signal.

7. The display system according to claim 5, further comprising an OSD generator displaying an OSD screen for controlling the display state of the image, wherein the display controller controls the OSD generator to display the OSD screen when the inputted key signal is recognized as the second control signal.

8. The display system according to claim 5, wherein the display controller turns power on or off according to the first control signal when the inputted key signal is recognized as the first control signal.

9. The display system according to claim 8, wherein the display controller recognizes the key signal as the first control signal to turn the power on or off according to the first control signal when the key signal is inputted from the key signal input part while the image signal is not received from the image signal source.

10. The display system according to claim 2, wherein the display controller recognizes the inputted key signal as the second control signal when the key signal is inputted from the key signal input part while the display state configuration program does not transfer information on whether the user'"'"'s access to the GUI is limited or not to the display controller.

11. The display system according to claim 10, wherein a state that the display state configuration program does not transfer the information on whether the user'"'"'s access to the GUI is limited or not comprises a state that the image signal source drives by a separate operating system other than the operating system with which the display state configuration program is compatible.

12. The display system according to claim 2, wherein the display state configuration program outputs a function preservation signal if the user'"'"'s access to the GUI is not limited.

13. The display system according to claim 2, wherein the display state configuration program outputs a function shift signal if the user'"'"'s access to the GUI is limited.

14. The display system according to claim 12, wherein the display state configuration program outputs the function preservation signal continuously if determined that the user'"'"'s access to the GUI is not limited, and blocks the output of the function preservation signal if the user'"'"'s access to the GUI is limited.

15. A method of controlling a display state of an image provided by an image producing apparatus, the method comprising:

generating a key signal according to a manipulation of a key on a display;

when the key is manipulated and if it is determined that access to a graphical user interface (GUI) provided by the image producing apparatus is not limited, recognizing the inputted key signal as a first control signal to implement a pre-set control function according to the recognized first control signal; and

when the key is manipulated and if it is determined that access to the GUI is limited, recognizing the inputted key signal as a second control signal to control the display state of the image according to the recognized second control signal.

16. The method according to claim 15, wherein a display state configuration program outputs a function preservation signal if the user'"'"'s access to the GUI is not limited.

17. The method according to claim 15, wherein a display state configuration program outputs a function shift signal if the user'"'"'s access to the GUI is limited.

18. The method according to claim 15, wherein a display state configuration program outputs a function preservation signal continuously if determined that the user'"'"'s access to the GUI is not limited, and blocks the output of the function preservation signal if the user'"'"'s access to the GUI is limited.

19. The method according to claim 15, further comprising:

receiving at the display a function preservation signal generated by the image producing apparatus if the access to the GUI is not limited; and

determining whether access to the GUI is limited according to the received function preservation signal.

20. The method according to claim 15, further comprising, when the key is not manipulated and the access to the GUI is not limited, changing the display state according to a manipulation of the GUI.

21. The method according to claim 20, further comprising, when the key is not manipulated and the access to the GUI is not limited, generating the GUI on the display using a program resident on the image producing apparatus.

22. A computer readable medium encoded with processing instructions for performing a method of controlling a display state of an image provided by an image producing apparatus performed by a computer connected to an image producing apparatus, the method comprising:

receiving a generated key signal according to a manipulation of a key on a display;
