1. A method of generating a depth image of a scene comprising the steps of:

  • (a) providing first and second digital images of said scene derived at first and second scene observation locations spatially spaced apart from one another;

    (b) for a plurality of spatially separated scene observation locations, spaced apart from one another and spaced apart from said first and second scene observation locations and associated with respective missing images of said depth image, generating missing angular digital images of said scene in accordance with an iteratively refined set of disparity vector fields that associate said plurality of spatially separated scene observation locations with said first and second digital images; and

    (c) interlacing said missing angular digital images of said scene and said first and second digital images to derive said depth image.
