1. A method for generating a shallow depth of field effect for a digitally captured image, at least one region of interest and at least one non-interest region being defined in the captured image, the method comprising: retrieving a previously stored captured image from a memory, metadata having been stored with the captured image, the metadata containing focus information for each of the at least one region of interest and the at least one non-interest region; calculating, for each non-interest region, a difference in focus between the at least one region of interest and the non-interest region using the focus information contained in the metadata; determining, for each non-interest region, a degree of blur to be applied to the non-interest region, based on the calculated difference in focus; applying the determined degree of blur to each non-interest region, to generate a blurred image; and displaying the blurred image on a display.
