Claim:
1. A computer-implemented method for providing image refocusing comprising: determining an all in focus reference image and generating a basic refocused image based on a plurality of images received via a camera array; taking a difference of the all in focus reference image and the basic refocused image to generate a difference image; and applying a space variant filter based at least in part on the difference image to the basic refocused image to generate a final refocused image having a region of increased blur with respect to the all in focus reference image, wherein applying the space variant filter based on the difference image comprises increasing blur by a greater amount in a first region than in a second region of the basic refocused image, wherein the first region is associated with a first difference in the difference image and the second region is associated with a second difference in the difference image, and wherein the first difference is greater than the second difference.
