Abstract
A method is performed to refocus a digital photographic image comprising a plurality of pixels. In the method, a set of images is computed corresponding to the digital photographic image and focused at different depths. Refocus depths for at least a subset of the pixels are identified and stored in a look-up table. At least a portion of the digital photographic image is refocused at a desired refocus depth determined from the look-up table.
