Abstract

Provided are an apparatus for processing adaptive video and a method of scaling video, which generate a graphical user interface (GUI) so that a GUI suitable for the screen size of a display device can be displayed according to the screen size of the display device. The apparatus can realize a GUI most suitable for the screen size of an external display device connected to the apparatus by enlarging or reducing the size of the GUI according to the screen size of the external display device, or by changing the arrangement of items arranged on the GUI.

Claims

1. An apparatus for processing an image, the apparatus comprising:

a display having a screen and configured to display a first image and a second image on the screen of the display;

a processor configured to determine a first scaling ratio of the first image based on a size of a screen of a target device external to the apparatus;

a video scaler configured to scale the first image according to the determined first scaling ratio of the first image; and

a transmitter configured to transmit the scaled first image to the target device,

wherein the first image is displayed in the second image, and

wherein the first scaling ratio of the first image is different from a second scaling ratio of the second image.

2. The apparatus of claim 1, wherein the first image has a first horizontal dimension and a first vertical dimension, the second image has a second horizontal dimension and a second vertical dimension, the screen of the target device has a third horizontal dimension and a third vertical dimension, and a ratio of the first horizontal dimension of the first image to the third horizontal dimension of the screen of the target device is different from a ratio of the second horizontal dimension of the second image to the third horizontal dimension of the screen of the target device or a ratio of the first vertical dimension of the first image to the third vertical dimension of the screen of the target device is different from a ratio of the second vertical dimension of the second image to the third vertical dimension of the screen of the target device.

3. The apparatus of claim 1, wherein the first scaling ratio is an enlargement ratio or a reduction ratio of at least one of horizontal and vertical image dimensions of the first image.

4. The apparatus of claim 1, wherein the first image is a graphic user interface (GUI).

5. The apparatus of claim 1, wherein the processor is configured to read information about dimensions of the screen of the target device from an external server or the target device through a network.

6. A method of scaling image data, the method comprising:

displaying a first image and a second image on a screen of a display of an apparatus;

determining a first scaling ratio of the first image based on a size of a screen of a target device external to the apparatus;

scaling the first image according to the determined first scaling ratio of the first image; and

transmitting the scaled first image to the target device,

wherein the first image is displayed in the second image; and

wherein the first scaling ratio of the first image is different from a second scaling ratio of the second image.

7. The method of claim 6, wherein the first image has a first horizontal dimension and a first vertical dimension, the second image has a second horizontal dimension and second vertical dimension, the screen of the target device has a third horizontal dimension and a third vertical dimension, and a ratio of the first horizontal dimension of the first image to the third horizontal dimension of the screen of the target device is different from a ratio of the second horizontal dimension of the second image to the third horizontal dimension of the screen of the target device or a ratio of the first vertical dimension of the first image to the third vertical dimension of the screen of the target device is different from a ratio of the second vertical dimension of the second image to the third vertical dimension of the screen of the target device.

8. The method of claim 6, wherein the first scaling ratio is an enlargement ratio or a reduction ratio of at least one of horizontal and vertical image dimensions of the first image.

9. The method of claim 6, wherein the first image is a graphic user interface (GUI).

10. The method of claim 6, further comprising reading information about dimensions of the screen of the target device from an external server or the target device through a network.
