Claim One:
1. A method for blurring an image projected from light field data, comprising: retrieving an image projected from light field data, wherein the image comprises a plurality of pixels, each of which encodes a color value and a depth value; and at a processor, calculating a blurred color value of a subject pixel of the image by: calculating a first circle of confusion proximate coordinates of the subject pixel for a first depth; calculating a second circle of confusion proximate coordinates of the subject pixel for a second depth greater than the first depth; retrieving the color values for a first set of pixels, wherein each pixel in the first set lies within the first circle of confusion and has a depth value proximate the first depth; retrieving the color values for a second set of pixels, wherein each pixel in the second set lies within the second circle of confusion, has a depth value proximate the second depth, and is not occluded by the first set of pixels; and selecting the blurred color value based on the color values of the first set of pixels and the color values of the second set of pixels.
