Abstract: A method for preparing immersive video data prior to processing into an immersive video. The method comprises receiving immersive video data containing one or more images of a scene, the scene comprising one or more image regions, and obtaining a relevance factor for at least one of the image regions, the relevance factor being indicative of the relative importance of the image region to a viewer. The immersive video data is separated into one or more sets of region data, wherein each set of region data corresponds to the data of one or more image regions and, based on the relevance factor of an image region, a bitrate is selected at which the set of region data corresponding to the image region is to be sent to an external processing unit.

Abstract: An apparatus is arranged to generate a triangle mesh for a three dimensional image. The apparatus includes a depth map source (101) which provides a depth map and a tree generator (105) generates a k-D tree from the depth map. The k-D tree representing a hierarchical arrangement of regions of the depth map satisfying a requirement that a depth variation measure for undivided regions is below a threshold. A triangle mesh generator (107) positions an internal vertex within each region of the k-D tree. The triangle mesh is then generated by forming sides of triangles of the triangle mesh as lines between internal vertices of neighboring regions. The approach may generate an improved triangle mesh that is suitable for many 3D video processing algorithms.

Abstract: A display backlight comprises an edge-lit waveguide having an array of light out-coupling structures which for example each comprise a projection into the waveguide. Each projection has a beam redirecting face which is at an angle a to the normal. The angle a and the refractive index of the waveguide as well as outside the waveguide (over the output face) are designed to satisfy various relationships, which ensure that the optical output can be selected to be within a desired angular range in a generally forward direction (and thus not clipped).

Abstract: An autostereoscopic 3D display comprises a first unit (503) for generating an intermediate 3D image. The intermediate 3D image comprises a plurality of regions and the first unit (503) is arranged to generate a first number of image blocks of pixel values corresponding to different view directions for the region regions. The number of image blocks is different for some regions of the plurality of regions. A second unit (505) generates an output 3D image comprising a number of view images from the intermediate 3D image, where each of the view images correspond to a view direction. The display further comprises a display arrangement (301) and a driver (507) for driving the display arrangement (301) to display the output 3D image. An adaptor (509) is arranged to adapt the number of image blocks for a first region in response to a property of the intermediate 3D image or a representation of a three dimensional scene from which the first image generating unit (503) is arranged to generate the intermediate image.

Abstract: An autostereoscopic display device comprises a display panel and a lenticular array provided over the display panel. The lenticular array comprises an array of lenticular lenses each having a parallel elongate axis and arranged side by side in a pitch direction. The display panel comprises a shutter type display, with a transition between light modulating state involving movement of the light modulating medium generally in a direction perpendicular to the lenticular pitch direction.

Abstract: A 3D video system transfers video data from a video source device (40) to a destination device (50). The destination device has a destination depth processor (52) for providing destination depth data. The source device provides depth filtering data including filter location data, the depth filtering data representing a processing condition for processing the destination depth data in a filter area of the video indicated by the filter location data. The destination depth processor (52) is arranged for processing, in dependence on the depth filtering data, the destination depth data in an area of the video indicated by the filter location data. The depth filtering data enables the rendering process to improve the quality of the depth data.
