Abstract

Movable image capture devices and methods for images from behind a display screen are disclosed. According to an aspect, a method includes determining a position of a displayed target image on a display screen. The method also includes using an image capture device positioned behind the display screen for capturing images positioned in front of the display screen. The method also includes moving the image capture device behind the display screen to a position near the position of the displayed target image based on the determined position of the displayed target image.

First claim

What is claimed is:

1. A method comprising:
determining a position of a displayed target image on a display screen;
using an image capture device positioned behind the display screen that captures an image positioned in front of the display screen;
moving the image capture device behind the display screen to a position near the position of the displayed target image based on the determined position of the displayed target image;
determining a rate of movement of the displayed target image on the display screen;
controlling display of video of the target image on the display screen based on the rate of movement; and
reducing a motion effect of the displayed video of the target image while the image capture device is moving in accordance with the rate of movement.

2. The method of claim 1 , further comprising receiving image data for displaying the target image on the display screen, and
wherein determining the position of the displayed target image within a display area of the display screen is based on image analysis performed on the received image data from the image capture device.

3. The method of claim 2 , wherein determining a position of the displayed target image comprises determining the position based on coordinate information in the image data.

4. The method of claim 1 , wherein determining the position of the displayed target image comprises applying an image recognition technique for determining a position of a face of a person.

5. The method of claim 1 , further comprising controlling the display screen to be substantially transparent at the position of the displayed target image.

6. The method of claim 1 , wherein determining a position of the displayed target image comprises performing audio analysis on multimedia data to determine the position of a speaking source.

7. The method of claim 6 , wherein the multimedia data includes sound data associated with a plurality of different images for display on the display screen,
wherein the method further comprises determining a primary source of sound among the different images, and
wherein moving the image capture device comprises moving the image capture device behind the display screen to a position near the primary source of sound.

8. The method of claim 1 , further comprising:
determining that the displayed target image moves to another position on the display screen; and
moving the image capture device behind the display screen to a position near the other position of the displayed target image.

9. A system comprising:
at least one processor and memory, wherein the memory includes instructions, which when executed by the processor, cause the system to:
determine a position of a displayed target image on a display screen;
use an image capture device positioned behind the display screen to capture images positioned in front of the display screen;
move the image capture device behind the display screen to a position near the position of the displayed target image based on the determined position of the displayed target image;
determine a rate of movement of the displayed target image on the display screen;
control display of video of the target image on the display screen based on the rate of movement; and
reduce a motion effect of the displayed video of the target image while the image capture device is moving in accordance with the rate of movement.

10. The system of claim 9 , further configured to receive image data for displaying the target image on the display screen, and
determine the position of the displayed target image within the display area of the display screen based on image analysis performed on the image data received from the image capture device.

11. The system of claim 10 , wherein the at least one processor and memory i-s further configured to determine the position of a displayed target object based on coordinate information in the image data.

12. The system of claim 9 , wherein the at least one processor and memory is further configured to apply an image recognition technique to determine a position of a face of a person.

13. The system of claim 9 , wherein the at least one processor and memory controls the display screen to be substantially transparent at the position of the displayed target image.

14. The system of claim 9 , wherein the at least one processor and memory is further configured to perform audio analysis on multimedia data to determine the position of a speaking source.

15. The system of claim 14 , wherein the multimedia data includes sound data associated with a plurality of different images for display on the display screen,
wherein the system is further configured to determine a primary source of sound among the different images, and
wherein the system is further configured to move the image capture device behind the display screen to a position near the primary source of sound.

16. The system of claim 9 , wherein the at least one processor and memory:
determines that the displayed target image moves to another position on the display screen; and
moves the image capture device behind the display screen to a position near the other position of the displayed target image.
