1. A device comprising circuitry configured to:
obtain a plurality of initial two-dimensional, 2D, images which together represent an initial three-dimensional, 3D, image, wherein each initial 2D image is associated with one of a plurality of focal planes, wherein an object in an initial 2D image associated with a given focal plane among the plurality of focal planes is identified based on the object having a predefined intensity;
generate one or more blurred versions of each of the plurality of initial 2D images on one or more of the focal planes other than its associated focal plane;
generate a high passed version of each of the plurality of initial 2D images on its associated focal plane; and
generate a plurality of final 2D images by generating for each focal plane a final 2D image based on the high passed version of the initial 2D image associated with that focal plane and the one or more blurred versions generated on that focal plane from one or more of the other initial 2D images.
