1. Integral Photography A Method for Implementing 3D Video Systems

2. Outline What is Integral Photography? Problems and Solutions An experimental System Remaining Drawbacks

3. What is Integral Photography? Proposed by Lippman in 1908 Similar to Holography Autostereoscopic

4. Elemental Images Miniature images of the view through each lens

5. Problems Depth Inversion Image Inversion Optical Crosstalk Depth Error

6. Depth Inversion Convex objects appear concave Can be solved via a second image capture or via orthoscopic viewing

7. Image Inversion The image capture on film appears inverted Can be solved by rotating the film 180* before viewing

8. Optical Crosstalk Caused when light rays from multiple sources strike same pixel of film Solved via GRIN (gradient-index) lense array

9. Depth Error Objects far from the lens array have their depths poorly estimated Solved via a secondary depth control lense

10. An Experimental Real-time System

11. Remaining Drawbacks Requires extremely high resolution –~Ne² times more than 2D imaging –Ne is the number of pixels per elemental image

12. Conclusion Theoretically a very good approach Current Implementations limited by resolution of image capture and display devices
