Abstract

An image display device including a display configured to display a first image is provided. The image display device includes a controller configured to generate a second image by enlarging a part of the first image displayed in a first region of the display and to control the display to display a part of the second image in the first region, and a sensor configured to sense a user input for moving the second image. In response to the user input, the controller is configured to control the display to move and display the second image, within the first region.

Claims

1. An image display device comprising:

a display configured to display a first image;

a controller configured to;

generate a second image by enlarging a part of the first image displayed in a first region of the display, and

control the display to display a part of the second image in the first region; and

a sensor configured to sense a user input for moving the second image,

wherein, in response to the user input, the controller controls the display to move and display the second image, within the first region.

2. The image display device of claim 1,

wherein the sensor is configured to sense an arrow key input, and

wherein the controller is configured to control so that the second image is moved in a direction corresponding to the sensed arrow key input and displayed.

3. The image display device of claim 1,

wherein the display is configured to display an icon representing a movable direction of the second image.

4. The image display device of claim 1,

wherein the sensor is configured to sense an input for zooming in or out the second image, and

wherein the controller is configured to:

zoom in the second image in response to the sensed zoom-in input, or

zoom out the second image in response to the sensed zoom-out input.

5. The image display device of claim 1,

wherein the controller is configured to:

detect an object of interest in the first image, and

set a region in which the detected object of interest is displayed as the first region.

6. The image display device of claim 5,

wherein the controller is configured to:

detect text in the first image, and

set a region in which the text is displayed as the first region.

7. An image display device comprising:

a display configured to display a first image including at least one object;

a sensor configured to sense a user input for selecting an object of interest from among the at least one object; and

a controller configured to;

detect the object of interest in the first image,

generate a second image by enlarging the detected object of interest, and

control the display to display the second image.

8. The image display device of claim 7,

wherein the controller is configured to:

detect the at least one object included in the first image, and

perform control so that a candidate list including the detected at least

one object is displayed on the display, and

wherein the user input is an input for selecting the object of interest from among the at least one object included in the candidate list.

9. The image display device of claim 7,

wherein the controller is configured to:

adjust a magnification of the object of interest according to a size of the object of interest displayed on the display, and

enlarge the object of interest according to the adjusted magnification.

10. The image display device of claim 7,

wherein, when a size of the object of interest displayed on the display is equal to or larger than a threshold value, the controller is configured to control the display to display the object of interest without enlarging the object of interest.

11. The image display device of claim 7,

wherein the controller is configured to control the display to display the second image to overlap a region in which the object of interest is displayed.

12. An operating method of an image display device, the operating method comprising:

displaying a first image on a display;

generating a second image by enlarging a part of the first image displayed in a first region of the display;

displaying a part of the second image in the first region;

sensing a user input for moving the second image; and

moving and displaying the second image in the first region in response to the user input.

13. The operating method of claim 12,

wherein the sensing of the user input comprises sensing an arrow key input, and

wherein the moving and displaying of the second image comprises moving the second image in a direction corresponding to the sensed arrow key input and displaying the moved second image.

14. The operating method of claim 12, further comprising displaying an icon representing a movable direction of the second image.

15. The operating method of claim 12, further comprising:

sensing an input for zooming in or out the second image; and

zooming in the second image in response to the sensed zoom-in input, or zooming out the second image in response to the sensed zoom-out input.

16. The operating method of claim 12, further comprising:

detecting an object of interest in the first image; and

setting a region in which the detected object of interest is displayed as the first region.

17. The operating method of claim 16, wherein the detecting of the object of interest in the first image and the setting of the region in which the detected object of interest is displayed as the first region comprises:

detecting text in the first image; and

setting a region in which the text is displayed as the first region.

18. A non-transitory computer readable recording medium configured to store program instructions, that when executed by at least one processor of an image display device, cause the at least one processor to control the image display device perform the operating method of claim 12.
