Embodiment Construction

[0018] It should be appreciated that the drawings and description of the present invention have been simplified to illustrate elements that are relevant to a clear understanding of the present invention, while many other elements that are present in typical digital multimedia content delivery methods and systems have been eliminated for the sake of clarity. However, since these elements are well known in the art, a detailed discussion of these elements is not provided here. The disclosure herein refers to all such changes and modifications.

[0019] figure 1 is a prior art description of a plenoptic microimage matrix using a color filter array (CFA) used in the demosaicing process. As known to those skilled in the art, demosaicing is the technique of processing digital images by reconstructing incomplete color samples output from an image sensor covered with figure 1 The filter used in the CFA. Color filter arrays for demosaicing are digital image processing techniques that...

Abstract

A system and method for generating high-resolution images using a plenoptic camera having an image sensor and a main lens in front of a microlens array, characterized by comprising: a birefringent medium between the microlens arrays, capturing a first set of images in a first inactive state of operation, the inactive state of the birefringent medium providing ordinary light to each pixel; applying a voltage across the refractive medium causes the first inactive state to change to a second activated state; a second set of images is captured in the second activated state, the activated state of the birefringent medium converting light from the main lens Separation into ordinary rays and special rays that are offset on the image sensor from the ordinary rays by a distance of half a pixel; subtracted from at least twice the pixel value associated with the second set of images pixel values ​​associated with said first set of images and generate a final set of images with high resolution from said subtraction and said first set of images.

Description

technical field [0001] The present disclosure relates generally to digital image processing, and more particularly to plenoptic imaging techniques using demosaicing. Background technique [0002] This section is intended to introduce the reader to various aspects of art, which may be related to various aspects of the present invention that are described and / or claimed below. It is believed that this discussion helps to provide the reader with background information for a better understanding. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art. [0003] Photography produces persistent images by recording light or other electromagnetic radiation. The image is captured electronically by means of an image sensor or chemically by means of a photosensitive material. In a conventional camera, during a timed exposure, a lens is used to focus the light reflected or emitted from the subject into an actual imag...
