    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).

    摘要: A system of processing of three dimensional [3D] image data for display on a 3D display for a viewer is described. 3D display metadata defines spatial display parameters of the 3D display such as depth range supported by the 3D display. Viewer metadata defines spatial viewing parameters of the viewer with respect to the 3D display, such as viewing distance or inter-pupil distance. Source 3D image data arranged for a source spatial viewing configuration is processed to generate target 3D display data for display on the 3D display in a target spatial viewing configuration. First the target spatial configuration is determined in dependence of the 3D display metadata and the viewer metadata. Then, the source 3D image data is converted to the target 3D display data based on differences between the source spatial viewing configuration and the target spatial viewing configuration.

    摘要: A system of controlling displaying of image data has a source device (10), for example a BD player, which processes source image data for outputting the image data in dependence of first display parameters, and has a user control (15) for controlling the display parameters. The image data is transferred from the source device to a display device (13), which displays the image data in dependence of further display parameters, and has a further user control (16) for setting the further display parameters. The source device provides a display control mask structure, which is transferred with the image data to the display device. The display device displays the image data in dependence of the display control mask structure by masking said setting of the further display parameters according to the display control mask structure. Advantageously in a 3D system the depth settings of the display device are controlled based on the display control mask structure based on data from the content author

    摘要: An apparatus that contains an instruction processing circuit (14), a main memory (18) addressable by the instruction processing circuit (14) and a cache memory (16). In a normal mode the cache memory (16) is used to cache a part of data and/or instructions that the instruction processing circuit (14) addresses in the main memory (18) during execution, and to substitute cached data and/or instructions when the instruction processing circuit (14) addresses the data and/or instructions in the main memory (18). The circuit is able to switch to a low power operating mode. Upon the switch an interrupt program for executing a function during operation in the low power operating mode is loaded into the cache memory (16) from the main memory (18). Power supply to the main memory (18) is then switched off, but keeping at least a part of the cache memory (16) continuous to receive power supply. This part ensures that the program of instructions for executing the function is available to the instruction processing circuit. The program is executed from said at least part of the cache memory (16) in the low power operating mode.
