VERSATILE 3-D PICTURE FORMAT

摘要

A 3-D PICTURE IS PROVIDED AS FOLLOWS. A PAIR OF PICTURES (LP, RP) IS PROVIDED THAT COMPRISES A FIRST PICTURE (LP) BEING INTENDED FOR ONE EYE OF A VIEWER, AND A SECOND PICTURE (RP) BEING INTENDED FOR THE OTHER EYE OF THE VIEWER. IN ADDITION, A DEPTH MAP (DM) SPECIFICALLY DEDICATED TO THE FIRST PICTURE (LP) IS PROVIDED. THE DEPTH MAP (DM) COMPRISES DEPTH INDICATION VALUES. A DEPTH INDICATION VALUE RELATES TO A PARTICULAR PORTION OF THE FIRST PICTURE (LP) AND INDICATES A DISTANCE BETWEEN AN OBJECT AT LEAST PARTIALLY REPRESENTED BY THAT PORTION OF THE FIRST PICTURE AND THE VIEWER. SUCH A 3-D PICTURE ALLOWS A SATISFACTORY 3-D VISUAL RENDERING ON A GREAT VARIETY OF DISPLAY DEVICES. PREFERABLY, THE 3-D PICTURE IS SUPPLEMENTED WITH RENDERING GUIDANCE DATA (GD) THAT SPECIFIES RESPECTIVE PARAMETERS FOR RESPECTIVE RENDERING CONTEXTS. THESE RESPECTIVE PARAMETERS PREFERABLY RELATE TO GENERATING A SHIFTED VIEWPOINT PICTURE FROM THE FIRST PICTURE (LP) AND THE DEPTH MAP (DM).
