Method and system for encoding a 3D image signal, encoded 3D image signal, method and system for decoding a 3D image signal

摘要

In a method for encoding a 3D signal comprising layered-depth images, the viewing area of further layers are (background layers) made to differ in size and/or shape from the viewing area of a reference view (foreground layers) and the 3D image signal is provided this with appropriate scaling data expressing the relation between the reference view viewing area and the one or more further layer's viewing area.

1. A method for encoding a 3D image signal, the encoded 3D image signal comprising a reference view data layer and one or more background data layers for the reference view data layer, wherein viewing areas covered by the one or more background data layers and the reference view data layer differ in size or shape, and the reference view data layer and the one or more background data layers provide data for different viewing directions, the method comprising:
generating scaling data between the reference view data layer and the one or more background data layers in order to express a relation between the viewing area covered by the reference view data layer and the viewing area covered by the one or more background data layers for the different viewing directions; wherein the viewing area covered by the one or more background data layers is scaled by the scaling data such that an edge of the viewing area covered by the one or more background data layers matches a corresponding edge of the viewing area covered by the reference view data layer along a viewing direction.
