Abstract

A multi-view image display apparatus is provided. The apparatus includes a crosstalk compensator configured to compensate for crosstalk with respect to multi-view images by using a crosstalk matrix defining the crosstalk that occurs between the multi-view images; a tracker configured to track a position of a user's face as a user's position is moved; a controller configured to determine at least two views to be provided as images for user's left and right eyes from among the multi-view images based on the tracked position of the user's face, and to control the crosstalk compensator to compensate for the crosstalk by applying a predetermined weight to the at least two determined views; and a display configured to display the multi-view images of which the crosstalk is compensated.

First claim

What is claimed is:

1. A multi-view image display apparatus comprising:
a tracker configured to track a position of a user's face according to a movement of the user; and
a processor configured to compensate for crosstalk with respect to multi-view image comprising a plurality of views using a crosstalk matrix defining the crosstalk that occurs between different views,
wherein the processor determines at least two views from among the plurality of views to be provided to the user's left and right eyes, based on the tracked position of the user's face and compensates for the crosstalk by applying a weight matrix that applies a predetermined weight to the at least two views to an inverse matrix of the crosstalk matrix, and
wherein the predetermined weight applied to the at least two views is higher than a weight which is applied to at least one remaining view among the plurality of views; and
a display configured to display the compensated multi-view image.

2. The multi-view image display apparatus of claim 1 , wherein
the processor determines the at least two views to be provided as the images for the user's left and right eyes, based on the tracked position of the user's face and a viewing distance.

3. The multi-view image display apparatus of claim 1 , wherein
the processor compensates for the crosstalk that occurs between the multi-view images by multiplying the inverse matrix of the crosstalk matrix to a pixel matrix comprising pixel values of the multi-view images.

4. The multi-view image display apparatus of claim 1 , wherein
the processor compensates for the crosstalk using the weight matrix that is configured to apply a predetermined weight to a different number of views depending on a viewing distance to the inverse matrix of the crosstalk matrix.

5. The multi-view image display apparatus of claim 1 , wherein
the processor compensates for the crosstalk by applying a weight matrix to the inverse matrix of the crosstalk matrix, that is configured to apply a predetermined weight to at least four views to be provided as images for left and right eyes of each of a plurality of users in response to there being the plurality of users.

6. The multi-view image display apparatus of claim 1 , wherein
the crosstalk matrix comprises a matrix that is predefined by considering characteristics of the display.

7. A method of controlling a multi-view image display apparatus, the control method comprising:
tracking a position of a user's face according to a movement of the user;
determining at least two views from among a plurality of views to be provided to left and right eyes of the user based on the tracked position of the user's face;
compensating for crosstalk by applying a weight matrix that applies a predetermined weight to the at least two views to an inverse matrix of a crosstalk matrix which defines the crosstalk with respect to multi-view images,
wherein the predetermined weight applied to the at least two views is higher than a weight which is applied to at least one remaining view among the plurality of views; and
displaying the compensated multi-view image.

8. The control method of claim 7 , wherein
the compensating for the crosstalk comprises determining the at least two views that will be provided as the images for the left and right eyes of the user based on the tracked position of the user's face and a viewing distance, and compensating for the crosstalk by applying the predetermined weight to the at least two determined views.

9. The control method of claim 7 , wherein
the compensating for the crosstalk comprises compensating for the crosstalk that occurs between the multi-view images by multiplying the inverse matrix of the crosstalk matrix to a pixel matrix which comprises pixel values of the multi-view images.

10. The control method of claim 7 , wherein
the compensating for the crosstalk comprises compensating for the crosstalk by applying a weight matrix that applies a predetermined weight to a different number of views, depending on a viewing distance to the inverse matrix of the crosstalk matrix.

11. The control method of claim 7 , wherein
the compensating for the crosstalk comprises compensating for the crosstalk by in response to there being a plurality of users, using a weight matrix that applies a predetermined weight to at least four views to be provided as images for left and right eyes of each of the plurality of users to the inverse matrix of the crosstalk matrix.

12. The control method of claim 7 , wherein
the crosstalk matrix comprises a matrix that is predefined by considering characteristics of a display on which the multi-view images are displayed.

13. A multi-view image display apparatus comprising:
a crosstalk compensator configured to compensate for crosstalk with respect to multi-view images by using a crosstalk matrix which defines the crosstalk that occurs between the multi-view images;
a tracker configured to track a position of a user's face according to a movement of the user; and
a controller configured to determine at least two views from among multi-views to be provided as images for a user's left and right eyes, based on the tracked position of the user's face, and to control the crosstalk compensator to compensate for the crosstalk by applying a weight matrix which applies a predetermined weight to the at least two views to an inverse matrix of the crosstalk matrix,
wherein the predetermined weight applied to the at least two views is higher than a weight which is applied to at least one remaining view among the multi-views.

14. The multi-view image display apparatus of claim 13 , wherein the crosstalk compensator compensates for the crosstalk that occurs between the multi-view images by multiplying the inverse matrix of the crosstalk matrix to a pixel matrix comprising pixel values of the multi-view images.
