1. An image processing device arranged for remapping a depth map of a three-dimensional image, the image processing device comprising:
wherein the three-dimensional image comprises the depth map and a two-dimensional content image, wherein the depth map has depth pixels configured in a two-dimensional array at locations corresponding to locations of image pixels in the content image, wherein each of the depth pixels has a depth value, wherein the remapping comprises a global remapping function arranged to map of the depth values of the depth map to new depth values, a receiving unit arranged to receive a signal comprising the three-dimensional image and metadata coupled to the three-dimensional image, wherein the metadata comprises selection criteria based on at least the location and the depth value for selecting selected depth pixels corresponding to at least one object in the three-dimensional image, and a processing unit the processing unit comprising
a selection function arranged to retrieve, from the metadata, the selection criteria and the selected depth pixels, wherein the selected depth pixels correspond to at least one object in the three-dimensional image using the selection criteria;a determining function arranged to determine a local remapping function, wherein the local remapping function maps the depth values of the selected depth pixels to the new depth values; anda mapping function arranged to remap the depth map using the local remapping function for remapping the selected depth pixels and using the global remapping function for depth pixels other than the selected depth pixels. |
