REMAPPING A DEPTH MAP FOR 3D VIEWING

摘要

Image processing device (100) arranged for remapping a depth map (101) is disclosed. A 3D image comprises the depth map and a content image. The depth map has depth pixels in a 2D array. Each depth pixel has a depth value (203) and a location (201, 202). The remapping comprises a global remapping function (122). The image processing device comprises a processing unit (199) comprising: a selection function (110) for selecting depth pixels (112) that correspond to at least one object in the three-dimensional image using selection criteria based on at least location and depth value; a determining function (120) for determining a local remapping function (121) for remapping the object; and a mapping function (130) for remapping the depth map using the local remapping function for remapping the selected depth pixels and using the global remapping function for other depth pixels. The object is selected using selection criteria provided via metadata coupled to the 3D image.
