Title: APPARATUS AND METHOD FOR PROCESSING A DEPTH MAP
Abstract:
An apparatus for processing a depth map comprises a receiver (203) receiving an input depth map. A first processor (205) generates a first processed depth map by processing pixels of the input depth map in a bottom to top direction. The processing of a first pixel comprises determining a depth value for the first pixel for the first processed depth map as the furthest backwards depth value of: a depth value for the first pixel in the input depth map, and a depth value determined in response to depth values in the first processed depth map for a first set of pixels being below the first pixel. The approach may improve the consistency of depth maps, and in particular for depth maps generated by combining different depth cues.
