Method and apparatus for generating encoded content using dynamically optimized conversion for 3D movies

摘要

The present invention pertains to an apparatus and method for adding a graphic element, such as a subtitle to selected locations of the frames in a 3D movie. The authoring tool receives a depth map indicating the position of various objects in the frames of 3D content along a Z-axis. The authoring device then designates a position for at least one additional graphic element in at least some of the frames, these positions being determined in relation either to the positions of the objects or the position of the screen along said Z-axis. An encoder uses parameters from the authoring tool to reauthor the 3D movie by adding the graphic content to the positions designated by the parameters.

主权项

1. An apparatus for adding additional graphic content including subtitles to a 3D-movie formed of a group of frames, each frames including objects having coordinates at least in the Z-direction, the apparatus comprising:
a user interface adapted to receive from a user a designation of additional graphic content and placement information defining relative positions of said additional graphic content at least in the Z-direction selected for at least some of the frames of a plurality of frames with respect to at least one of said image elements within the respective frames; an authoring tool receiving a depth map indicating at least some of the coordinates of said objects within said frames, said authoring tool receiving said additional graphic content and said placement information from said user interface, said authoring tool in response generating parameters identifying at least a Z-position in the Z-direction for positioning said additional graphic content at a predetermined distance greater than zero in front of one of the objects within each frame; and an encoder receiving said 3D content and said parameters and generating an encoded 3D content including said additional graphic content at the Z-positions-designated by said placement information; wherein said 3D movie is preauthored to be presented on a screen of a first size and said authoring tool adjusts said position to adjust said subtitles if said 3D movie is to be shown on another screen having a different size.
