Abstract

Official abstract text for this publication.

According to various embodiments, the system and method of the present invention process light-field image data so as to reduce color artifacts, reduce projection artifacts, and/or increase dynamic range. These techniques operate, for example, on image data affected by sensor saturation and/or microlens modulation. Flat-field images are captured and converted to modulation images, and then applied on a per-pixel basis, according to techniques described herein.

First claim

Opening claim text (preview).

What is claimed is: 1. In a light-field image capture device having a plurality of microlenses, a method for compensating for sensor saturation and microlens modulation, comprising: in a processor, determining a flat-field response contour for each of at least one region of an image sensor; in the processor, generating a modulation image based on the at least one flat-field response contour; in the processor, generating a demodulation image from the modulation image; in the…
