Plenoptic sub-aperture view shuffling with improved resolution

摘要

A system and method for generating a high resolution image using a plenoptic camera having a main lens and an image sensor in front of a microlens array, the system and method being disposed between the main lens and the microlens array Using a birefringent medium to capture a first set of images in a first non-excited state of operation, wherein the non-excited state of the birefringent medium provides an ordinary ray to each pixel. And applying a voltage across the birefringent medium to cause the first non-excited state to become the second excited state and to capture the second image set in the second excited state. The excited state of the birefringent medium divides the light from the main lens into an ordinary ray and an extraordinary ray, and the extraordinary ray is reflected in the image sensor. Shifting by a distance of half a pixel from a ray; subtracting a pixel value associated with the first image set from a pixel value associated with the second image set at least twice; Generating a final image set with high resolution from one image set.
