3D SCREEN SIZE COMPENSATION

摘要

A device converts three dimensional [3D] image data arranged for a source spatial viewing configuration to a 3D display signal (56) for a 3D display in a target spatial viewing configuration. 3D display metadata has target width data indicative of a target width W t of the 3D display in the target spatial viewing configuration. A processor (52,18) changes the mutual horizontal position of images L and R by an offset O to compensate differences between the source spatial viewing configuration and the target spatial viewing configuration. The processor (52) retrieves source offset data provided for the 3D image data for calculating the offset O, and determines the offset O in dependence of the source offset data. Advantageously the 3D perception for the viewer is automatically adapted based on the source offset data as retrieved to be substantially equal irrespective of the screen size.
