Abstract
A system and method for generating high resolution images using a plenoptic camera, is provided. In one embodiment, the comprises capturing a first set of images in a first unexcited state of operation by using a birefringent medium disposed between a main lens and an array of lenses having a plurality of apertures. Each pixel of the first set of images is then mapped to a first set of apertures. The first unexcited state is then caused to become a second excited state by applying a voltage across said birefringent medium. A second set of images are captured in the second excited state and a second set of pixels of the second image is mapped to a second set of apertures. A value is calculated for each first and second set of images and the value associated with said first set of images is subtracted from at least two times the value calculated from said second set of image.
