Abstract

A method of displaying images, which includes displaying a first image in a first display portion, receiving a first image-quality condition for setting a first image quality of the first image displayed in the first display portion, generating, via a first display controller of the first display portion, a first image-quality setting image by applying the first image-quality condition to the first image displayed in the first display portion, transmitting the generated first image-quality setting image from the first display controller to a second display controller of a second display portion, and displaying the transmitted first image-quality setting image on the second display portion.

Claims

1. A method of displaying images, the method comprising:

displaying a first image in a first display portion;

displaying, on the first display portion, a user interface for receiving image-quality condition settings for the displayed first image from a remote controller;

receiving a first image-quality condition and a second image-quality condition for setting a first image quality of the first image and a second image-quality of the first image respectively through the user interface, the first image-quality condition and the second image-quality condition being different from each other;

generating, via a first display controller of the first display portion, a first image-quality setting image by applying the first image-quality condition to the first image and a second image-quality setting image by applying the second image-quality condition to the first image;

transmitting the generated first image-quality setting image and the generated second image-quality setting image from the first display controller to a second display controller of a second display portion; and

displaying the transmitted first image-quality setting image and the transmitted second image-quality setting image together on the second display portion˜

wherein the user-interface includes a menu with an apply button for applying the first and second image-quality conditions to the first image, and a view button for displaying thumbnail images of the generated first and second image-quality setting images side-by-side on the second display portion while the first image is simultaneously displayed on the first display portion.

2. The method of claim 1, further comprising:

receiving a selection signal indicating a selection of one of the first and second image-quality setting images displayed in the second display portion; and

displaying said selected one of the first and second image-quality setting images in the first display portion.

3. The method of claim 1, further comprising:

receiving a selection signal indicating a selection of one of the first and second image-quality setting images displayed in the second display portion; and

setting the first image displayed in the first display portion, without interrupting the displaying of the first image, to have an image-quality corresponding the first or second image-quality conditions of said selected one of the first and second image-quality setting images.

4. The method of claim 1, further comprising:

receiving a selection signal indicating a selection of the first image-quality setting image displayed in the second display portion; and

displaying said selected first image-quality setting image in the first display portion.

5. The method of claim 1, further comprising:

receiving a selection signal indicating a selection of the first image-quality setting image displayed in the second display portion; and

setting the first image displayed in the first display portion, without interrupting the displaying of the first image, to have an image-quality corresponding the first image-quality condition of the first image-quality setting image.

6. The method of claim 1, wherein the first and second display portions are included in a display device and are physically separated from each other and are connected together by an interface.

7. The method of claim 1, wherein the first image-quality condition includes at least one of a contrast, a brightness, a sharpness, a color saturation and a color to be applied to the first image.

8. The method of claim 1, wherein the first image is a moving image and the first image-quality setting image is a thumbnail still image of the first image.

9. The method of claim 1, wherein the first and second display portions are disposed on the same display device and are physically connected.

10. A display device, comprising:

a first display portion configured to display a first image;

a user-interface configured to receive a first image-quality condition and a second image-quality condition for setting a first image quality of the first image and a second image-quality of the first image respectively from a remote controller, the first image-quality condition and the second image-quality condition being different from each other;

a first display controller of the first display portion configured to generate a first image-quality setting image by applying the first image-quality condition to the first image and a second image-quality setting image by applying the second image-quality condition to the first image, and to transmit the generated first image-quality setting image and the generated second image-quality setting image to a second display controller; and

a second display portion physically separated from the first display portion and configured to display the transmitted first image-quality setting image and the transmitted second image-quality setting image together;

wherein the user-interface includes a menu with an apply button for applying the first and second image-quality conditions to the first image, and a view button for displaying thumbnail images of the generated first and second image-quality setting images side-by-side on the second display portion while the first image is simultaneously displayed on the first display portion.

11. The display device of claim 10, wherein the user-interface is further configured to receive a selection signal indicating a selection of one of the first and second image-quality setting images displayed in the second display portion, and

wherein the second display controller is further configured to display said selected one of the first and second image-quality setting images in the first display portion.

12. The display device of claim 10, wherein the user-interface is further configured to receive a selection signal indicating a selection of one of the first and second image-quality setting images displayed in the second display portion, and

wherein the first display controller is further configured to set the first image displayed in the first display portion, without interrupting the displaying of the first image, to have an image-quality corresponding the first or second image-quality conditions of said selected one of the first and second image-quality setting images.

13. The display device of claim 10, wherein the user-interface is further configured to receive a selection signal indicating a selection of the first image-quality setting image displayed in the second display portion, and

wherein the first display controller is further configured to display said selected first image-quality setting image in the first display portion.

14. The display device of claim 10, wherein the user-interface is further configured to receive a selection signal indicating a selection of the first image-quality setting image displayed in the second display portion, and

wherein the first display controller is further configured to set the first image displayed in the first display portion, without interrupting the displaying of the first image, to have an image-quality corresponding the first image-quality condition of the first image-quality setting image.

15. The display device of claim 10, wherein the first and second display portions are physically separated from each other and are connected together by an interface.

16. The display device of claim 10, wherein the first image-quality condition includes at least one of a contrast, a brightness, a sharpness, a color saturation and a color to be applied to the first image.

17. The display device of claim 10, wherein the first image is a moving image and the first image-quality setting image is a thumbnail still image of the first image.

18. The display device of claim 10, wherein the first and second display portions are disposed the same display device and are physically connected.
