Imaging through a display screen

1. A system, comprising:

a poriferous display screen having generally opposing front and back surfaces;

a projector positioned generally in front of the poriferous display screen and configured to project a first image on the front surface of the poriferous display screen;

a camera positioned behind the poriferous display screen and proximate to the back surface to capture a second image through the poriferous display screen;

a controller configured to alternatively activate and deactivate the projector and the camera at a combined rate of at least one hundred Hertz; and,

an image enhancement component configured to reduce artifacts in the second image caused by the poriferous display screen.

2. The system of claim 1 , wherein the projector is positioned above an intended viewing area from which a user can see the first image on the front surface.

3. The system of claim 1 , wherein the poriferous display screen comprises a mesh or a solid material having holes formed therein between the front and back surfaces or wherein the poriferous display screen comprises a black matrix having white dots screen printed thereon.

4. The system of claim 3 , wherein the holes occur only proximate the camera or the holes are formed throughout a majority of the poriferous display screen.

5. The system of claim 1 , wherein the poriferous display screen comprises about 90% to about 95% reflective material and about 5% to 10% holes.

6. The system of claim 1 , wherein the camera includes multiple lenses and wherein the multiple lenses are positioned against the back surface.

7. The system of claim 1 , wherein the camera is a video camera.

8. A system, comprising:

a poriferous display screen having generally opposing front and back surfaces, the poriferous display screen consisting of a solid material with multiple pores formed therein;

a projector positioned generally in front of the poriferous display screen and configured to project a first image on the front surface of the poriferous display screen such that the first image is visible on the solid material;

a camera positioned behind the poriferous display screen and proximate to the back surface to capture a second image through at least two of the multiple pores in the solid material;

a controller configured to alternatively activate and deactivate the projector and the camera at a combined rate of at least one hundred Hertz; and,

an image enhancement component configured to reduce artifacts in the second image caused by the solid material of the poriferous display screen.

9. The system of claim 8 , wherein the multiple pores are formed throughout a majority of the poriferous display screen.

10. The system of claim 8 , wherein about 90% to about 95% of an area of the poriferous display screen comprises the solid material and about 5% to 10% of the area comprises the multiple pores.

11. The system of claim 10 , wherein the artifacts in the second image are noise artifacts caused by the solid material of the poriferous display screen.

12. The system of claim 8 , wherein the poriferous display screen is defocused in the second image, and wherein the image enhancement component is configured to analyze a blurring diameter of the defocused poriferous display screen.

13. The system of claim 8 , wherein the artifacts in the second image are noise artifacts caused by the poriferous display screen, and the image enhancement component is configured to reduce the noise artifacts by video de-noising.

14. The system of claim 13 , wherein the video de-noising includes temporal de-noising.
