Title: PLENOPTIC SUB APERTURE VIEW SHUFFLING FOR A RICHER COLOR SAMPLING
Abstract:
A system and method for generating multiple images with rich color acquisition using a plenoptic camera having a main lens disposed in front of a micro array of lenses, a mosaic color filter array and an image sensor, characterized in that it comprises: capturing a first set of images using an ordinary state of an electrically controllable birefringent medium being disposed between said main lens and said micro array of lenses, said ordinary state providing an ordinary ray to each pixel; capturing a second set of images using an extraordinary state of said electrically controllable birefringent medium, said extraordinary state splitting the light from said main lens into an ordinary ray and a extraordinary ray respectively impinging on two adjacent pixels of different colors, said extraordinary ray being shifted by distance of one pixel on said image sensor; performing a weighted subtraction of information about said second set of images from information about said first set of images; and generating a final set of images with rich color information from said weighted subtraction and said first set of images.
