Abstract

A display device for providing a virtual reality service is provided. The display device includes: a display configured to display a stereoscopic image; a user interface configured to receive a user command for enlarging or shrinking the stereoscopic image; and a processor configured to adjust a three-dimensional effect for the stereoscopic image to correspond to the user command when the user command is input, and control the display to display an enlarged image or a shrunk image in which the three-dimensional effect is adjusted.

First claim

The invention claimed is:

1. A display device for providing a virtual reality service, the display device comprising:
a display;
a user interface; and
a processor configured to:
based on a user command being input through the user interface, adjust a three-dimensional effect for a stereoscopic image to correspond to the user command,
control the display to display an enlarged image or a shrunk image in which the three-dimensional effect is adjusted, and
based on the user command being a command for enlarging the stereoscopic image, move a left-eye image of the stereoscopic image leftward, move a right-eye image of the stereoscopic image rightward, generate a left-eye stereoscopic space image and a right-eye stereoscopic space image based on the left-eye image moved leftward and the right-eye image moved rightward, and obtain images corresponding to the user command from each of the left-eye stereoscopic space image and the right-eye stereoscopic space image.

2. The display device of claim 1 , wherein the processor is further configured to:
control to project each of the left-eye image moved leftward and the right-eye image moved rightward into a virtual stereoscopic space to obtain the left-eye stereoscopic space image and the right-eye stereoscopic space image, and
control the display to display the images corresponding to the user command.

3. The display device of claim 2 , wherein the processor, when an entirety shrinking command to shrink an entirety of the stereoscopic image is input, is further configured to:
move the left-eye image rightward,
move the right-eye image leftward,
obtain the left-eye stereoscopic space image and the right-eye stereoscopic space image using each of the left-eye image moved rightward and the right-eye image moved leftward,
obtain images corresponding to the entirety shrinking command from each of the left-eye stereoscopic space image and the right-eye stereoscopic space image, and
control the display to display the images corresponding to the entirety shrinking command.

4. The display device of claim 1 , wherein the processor is further configured to:
control to project each of the left-eye image and the right-eye image of the stereoscopic image into a virtual stereoscopic space to obtain the left-eye stereoscopic space image and the right-eye stereoscopic space image,
control to rotate virtual cameras existing in the left-eye stereoscopic space image and the right-eye stereoscopic space image,
obtain images corresponding to the user command from each of the left-eye stereoscopic space image and the right-eye stereoscopic space image using the virtual cameras as rotated, and
control the display to display the images corresponding to the user command.

5. The display device of claim 4 , wherein the processor, when a portion enlarging command to enlarge a portion of the stereoscopic image is input, is further configured to:
control to rotate a virtual camera existing in the left-eye stereoscopic space image rightward,
control to rotate a virtual camera existing in the right-eye stereoscopic space image leftward,
obtain images corresponding to the portion enlarging command from each of the left-eye stereoscopic space image and the right-eye stereoscopic space image using the virtual cameras as rotated, and
control the display to display the images corresponding to the portion enlarging command to be overlaid on the left-eye image and the right-eye image, respectively.

6. The display device of claim 4 , wherein the processor, when a portion shrinking command to shrink a portion of the stereoscopic image is input, is further configured to:
control to rotate a virtual camera existing in the left-eye stereoscopic space image leftward,
control to rotate a virtual camera existing in the right-eye stereoscopic space image rightward,
obtain images corresponding to the portion shrinking command from each of the left-eye stereoscopic space image and the right-eye stereoscopic space image using the virtual cameras as rotated, and
control the display to display the images corresponding to the portion shrinking command to be overlaid on the left-eye image and the right-eye image, respectively.

7. A control method of a display device for providing a virtual reality service, the control method comprising:
displaying a stereoscopic image;
based on a user command for enlarging or shrinking the stereoscopic image being input, adjusting a three-dimensional effect for the stereoscopic image to correspond to the user command; and
displaying an enlarged image or a shrunk image in which the three-dimensional effect is adjusted,
wherein, if the user command corresponds to a command to enlarge the stereoscopic image, the displaying of the enlarged image comprises moving a left-eye image of the stereoscopic image leftward, moving a right-eye image of the stereoscopic image rightward, generating a left-eye stereoscopic space image and a right-eye stereoscopic space image based on the left-eye image moved leftward and the right-eye image moved rightward, and obtaining images corresponding to the user command from each of the left-eye stereoscopic space image and the right-eye stereoscopic space image.

8. The control method of claim 7 , wherein the displaying of the enlarged image or the shrunk image further comprises:
projecting each of the left-eye image moved leftward and the right-eye image moved rightward into a virtual stereoscopic space to obtain the left-eye stereoscopic space image and the right-eye stereoscopic space image;
obtaining the images corresponding to the user command from each of the left-eye stereoscopic space image and the right-eye stereoscopic space image; and
displaying the images corresponding to the user command.

9. The control method of claim 8 , wherein, when an entirety shrinking command to shrink an entirety of the stereoscopic image is input, the displaying of the enlarged image or the shrunk image further comprises:
moving the left-eye image rightward;
moving the right-eye image leftward;
obtaining the left-eye stereoscopic space image and the right-eye stereoscopic space image using each of the left-eye image moved rightward and the right-eye image moved leftward;
obtaining images corresponding to the entirety shrinking command from each of the left-eye stereoscopic space image and the right-eye stereoscopic space image; and
displaying the images corresponding to the entirety shrinking command.

10. The control method of claim 7 , wherein the displaying of the enlarged image or the shrunk image further comprises:
projecting each of the left-eye image and the right-eye image of the stereoscopic image into a virtual stereoscopic space to obtain the left-eye stereoscopic space image and the right-eye stereoscopic space image;
rotating virtual cameras existing in the left-eye stereoscopic space image and the right-eye stereoscopic space image;
obtaining images corresponding to the user command from each of the left-eye stereoscopic space image and the right-eye stereoscopic space image using the virtual cameras as rotated; and
displaying the images corresponding to the user command.

11. The control method of claim 10 , wherein, when a portion enlarging command to enlarge a portion of the stereoscopic image is input, the displaying of the enlarged image or the shrunk image further comprises:
rotating a virtual camera existing in the left-eye stereoscopic space image rightward;
rotating a virtual camera existing in the right-eye stereoscopic space image leftward;
obtaining images corresponding to the portion enlarging command from each of the left-eye stereoscopic space image and the right-eye stereoscop
