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 by detecting depth values occurring in the 3D image data and setting auxiliary depth values for the auxiliary graphical data 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 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 (3D) image and auxiliary data in a display area of a stereoscopic screen, the method comprising acts of:
obtaining information describing scaling and/or shifting for use with the 3D image; resizing the 3D image in accordance with the information by scaling and/or shifting in at least one of a horizontal direction and a vertical direction of a display area to create a spatial area fitting in a portion of the display area that is not occupied by the 3D image to be occupied by the auxiliary data; combining the scaled and/or shifted 3D image and the auxiliary data such that the auxiliary data is placed within the spatial area; creating a left border region and a right border region that extend into the portion of the display area that is occupied by the 3D image; and adjusting a depth position of the left and right border regions such that each border region is closer to a viewer than any of the portion of the 3D image in the display area that is overlapped by the left and right border regions.
