Patent ID: 7609906

Claim:
A computer implemented method for acquiring and displaying light fields, comprising, the steps of: reconstructing, according to an acquisition parameterization, a continuous light field from input samples of an input light field of a three dimensional scene acquired by a plurality of cameras; reparameterizing, according to a display parameterization, the continuous light field; and prefiltering the reparameterized light field and sampling the prefiltered light field to produce output samples having the display parametrization, and displaying the output samples as an output light field using a three dimensional display device, wherein the display parameterization is defined in part by a t-plane plane of the parallax-barrier defining t coordinates, and a v-plane of the lenticular screen defining v coordinates, and a pixel spacing of the lenticular screen is Δv, a spacing of the gaps in the parallax-barrier is Δt, a separation between the lenticular screen and parallax-barrier is f, and depth is z, and wherein a display bandwidth is limited according to H ⁡ ( ϕ , θ ) = { 1 for ⁢ ⁢  ϕ  ≤ π / Δ ⁢ ⁢ v and ⁢ ⁢  θ  ≤ π / Δ ⁢ ⁢ t 0 otherwise , where H is a display prefilter, and angular and spatial frequencies are, respectively, φ and θ.
