(EN) Identification of 3D format and graphics rendering on 3D displays
Abstract
(EN)

In one embodiment, a 3D display has an image processor including an overlay detector connected to a display controller. The image processor receives a 3D-compatible image stream from a 2D legacy device that may superimpose overlays, e.g., a 2D captions, over 3D-compatible images. The overlay detector automatically determines whether a received image comprises a caption overlay and, if so, provides the location and dimensions of the overlay to the display controller. The display controller processes the overlaid 3D-compatible image to isolate the caption characters of the caption overlay and generates, for a viewer of the 3D display, different left-eye and right-eye images, each including overlaid caption characters that substantially match the characters of the caption overlay. The result is the appearance, to the viewer, of a substantially flat and coherent caption overlay over a 3D image.
