Problem – 2D
Problem – 2.5D
Problem – 3D u s Conventional display are view-independent - Pixel intensity/color does not vary as a function of viewing angle
Problem – 3D pinhole u s Light Field display are view-dependent (automultiscopic) - Achieved with pinhole/lenslet array placed close to the display - Trades decreased spatial resolution for increased angular resolution
Problem – 3D lenslet u s Light Field display are view-dependent (automultiscopic) - Achieved with pinhole/lenslet array placed close to the display - Trades decreased spatial resolution for increased angular resolution
Solution Light field camera Light field display
Parallax Barrier Front Mask
Parallax Barrier Rear Mask
Light Field Analysis of Barriers
Time-Multiplexing using Shifted Pinholes
