Abstract
A light field imaging system includes a lens configured to collect light transmitted from an object; a polarizer configured to polarize the light; a polarization switching unit configured to repeatedly switch the polarization direction of the light in first and second polarization directions; first and second polarization dependent lens arrays configured to operate as a lens when the polarization direction of the light is the first and second polarization direction, respectively, and having a staggered arrangement; an image sensor configured to obtain a first image from the light collected by the first polarization dependent lens array and obtain a second image from the light collected by the second polarization dependent lens array; and an image processing unit configured to combine the first image and the second image to generate a high resolution image having higher resolution than the first image and the second image.
