Abstract

An apparatus for recognizing a pupillary distance for three-dimensional (3D) display includes a display configured to output a 3D image corresponding to a reference pupillary distance, a controller configured to control a viewing cone included in the 3D image, and a user inputter configured to receive a user feedback indicating whether an artifact is viewed in the 3D image in response to the controlling of the viewing cone. The controller may move the viewing cone within a margin corresponding to the reference pupillary distance, and change the reference pupillary distance or determine the reference pupillary distance to be a desired pupillary distance of the user based on the user feedback.

Claims

1. A method of recognizing a pupillary distance, comprising:

generating a three-dimensional (3D) image associated with a reference pupillary distance; and

determining a desired pupillary distance of a user based on a user feedback on the 3D image.

2. The method of claim 1, wherein the user feedback indicates whether an artifact is viewed in the 3D image.

3. The method of claim 2, further comprising:

changing the reference pupillary distance in response to the artifact being viewed in the 3D image.

4. The method of claim 1, further comprising:

determining a viewing zone corresponding to the reference pupillary distance; and

controlling a viewing cone of the 3D image within the viewing zone.

5. The method of claim 1, further comprising:

determining a viewing zone based on the user feedback, wherein the determining comprises determining a pupillary distance corresponding to the viewing zone to be the desired pupillary distance of the user.

6. The method of claim 1, further comprising:

controlling a viewing cone of the 3D image based on a received control command, the control command being based on input from the user.

7. An apparatus for recognizing a pupillary distance, comprising:

a three-dimensional (3D) image generator configured to generate a 3D image associated with a reference pupillary distance; and

a pupillary distance determiner configured to determine a desired pupillary distance of a user based on a user feedback on the 3D image.

8. The apparatus of claim 7, wherein the user feedback indicates whether an artifact is viewed in the 3D image.

9. The apparatus of claim 7, further comprising:

a viewing cone controller configured to control a viewing cone of the 3D image, and

wherein the viewing cone controller is configured to control the viewing cone within a viewing zone corresponding to the reference pupillary distance.

10. The apparatus of claim 7, further comprising:

a viewing zone determiner configured to determine a viewing zone based on the user feedback, and

wherein the pupillary distance determiner is configured to determine a pupillary distance corresponding to the viewing zone to be the desired pupillary distance of the user.

11. The apparatus of claim 7, further comprising:

a viewing cone controller configured to control a viewing cone of the 3D image based on a control command, the control command being based on an input received from the user.

12. An apparatus for recognizing a pupillary distance, comprising:

a display configured to output a three-dimensional (3D) image corresponding to a reference pupillary distance;

a controller configured to control a viewing cone of the 3D image; and

a user inputter configured to receive a user feedback indicating whether an artifact is viewed in the 3D image in response to the controlling of the viewing cone, and

wherein the controller is configured to determine a desired pupillary distance of a user based on the user feedback.

13. The apparatus of claim 12, wherein the controller is configured to determine a viewing zone based on the reference pupillary distance and positions of eyes of the user, and control the viewing cone within the viewing zone.

14. The apparatus of claim 12, wherein the controller is configured to change the reference pupillary distance based on the user feedback.

15. The apparatus of claim 12, wherein the controller is configured to control the viewing cone based on a control command, the control command being based on an input of the user, and the controller is configured to determine a viewing zone based on the user feedback, and determine a pupillary distance corresponding to the viewing zone to be the desired pupillary distance of the user.

16. The apparatus of claim 15, wherein the controller is configured to move at least one of a left image and a right image of the viewing cone based on the control command.

17. The apparatus of claim 15, wherein the user feedback relates to a margin in which the artifact is viewable by the user when eyes of the user deviate from the viewing zone, and

wherein the controller is configured to determine the margin based on the user feedback, and determine the viewing zone based on the margin.

18. The apparatus of claim 12, wherein the controller is configured to control the viewing cone by moving a virtual eye position of the viewing cone.

19. The apparatus of claim 12, wherein the viewing cone comprises a left viewing cone to be radiated to a left eye of the user and a right viewing cone to be radiated to a right eye of the user, and

the controller is configured to control the viewing cone by sequentially controlling the left viewing cone and the right viewing cone.

20. The apparatus of claim 12, further comprising:

a storage configured to store the desired pupillary distance of the user matched to identification information of the user.
