    摘要: A three dimensional [3D] video signal is processed in a video device (50). The device has generating means (52) for generating an output signal for transferring the video data via a high-speed digital interface like HDMI to a 3D display, which selectively generate a 3D display signal for displaying the 3D video data on a 3D display operative in a 3D mode, a 2D display signal for displaying 2D video data on the 3D display operative in a 2D mode, or a pseudo 2D display signal by including 2D video data in the output signal for displaying the 2D video data on the 3D display operative in the 3D mode. Processing means (53) detect a request to display 2D video data on the 3D display, while the 3D display is operative in the 3D mode, and, in response to the detection, the generating means are set to generate the pseudo 2D display signal for maintaining the 3D mode of the 3D display.

    摘要: An image encoding method that allows stereoscopic rendering basically comprises the following steps. In a primary encoding step (VDE1), a visual image is encoded in accordance with a standard. In an auxiliary encoding step (GRE), stereo-enabling data that is associated with the visual image is encoded as if the stereo-enabling data was an auxiliary image that can be combined with the visual image in accordance with the standard concerned. The stereo-enabling data comprises respective values that indicate respective distances between respective areas in the visual image and a virtual observer. In a composition definition step (CTR1), a composition definition is provided that causes a decoding device, which operates in accordance with the standard, to include the stereo-enabling data as a graphics image in at least one specific area of an output image, which can be transmitted to a display device.

    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.

    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).
