METHOD AND APPARATUS FOR COMBINING 3D IMAGE AND GRAPHICAL DATA

摘要

Three dimensional [3D] image data and auxiliary graphical data are combined for rendering on a 3D display (30) by detecting depth values occurring in the 3D image data, and setting auxiliary depth values for the auxiliary graphical data (31) adaptively in dependence of the detected depth values. The 3D image data and the auxiliary graphical data at the auxiliary depth value are combined based on the depth values of the 3D image data. First an area of attention (32) in the 3D image data is detected. A depth pattern for the area of attention is determined, and the auxiliary depth values are set in dependence of the depth pattern.

1. A method of combining three dimensional image data and auxiliary graphical data, the method comprising:
obtaining the three dimensional image data from an information carrier; combining the three dimensional image data and auxiliary graphical data on a display plane; obtaining shifting information from the information carrier; and shifting the three dimensional image data based on the shifting information,
wherein the shifting creates a black bar spatial area which is not occupied by the shifted three dimensional image data,wherein the black bar spatial area is created in an area of the display plane where no image data is displayed, wherein the shifting information comprises information signaling the presence of an allowed shifting for enabling the shifting of the three dimensional image data, wherein the shifting information comprises an offset in at least one of a horizontal direction of the display plane and a vertical direction of the display plane.
