Abstract
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.
