Abstract: The invention provides an autostereoscopic display which combines a display panel with a transparent mode and switchable optical arrangement for directing different views in different spatial directions to enable autostereoscopic viewing, and which also has a transparent mode. The display has (at least) at least a 3D autostereoscopic display mode in which the display is driven and the optical arrangement is used for generating views, and a transparent display mode in which the display and optical arrangement are driven to transparent modes to provide an undistorted view of the image behind the display.

Abstract: In the field of wireless communications, approaches for a reallocation and reservation of resources for high priority communications, for a Quality of Service, QoS, feedback, and for handling certain events in a wireless communication network are described. Embodiments relate to the implementation of such approaches for entities of a wireless communication network or system performing sidelink communications like V2X Mode 3 or Mode 4 UEs. In particular, improved approaches for a reallocation and reservation of resources for high priority communications, for a QoS feedback and for handling certain events in a wireless communication network are presented.

Abstract: A distribution system comprises an audio server (101) for receiving incoming audio from remote clients (103) and for transmitting audio derived from the incoming audio to the remote clients (103). An audio apparatus comprises an audio a receiver (401) which receives data comprising: audio data for a plurality of audio components representing audio from a remote client of the plurality of remote clients; and proximity data for at least one of the audio components. The proximity data is indicative of proximity between remote clients. A generator (403) of the apparatus generates an audio mix from the audio components in response to the proximity data. For example, an audio component indicated to be proximal to a remote client may be excluded from an audio mix for that remote client.

Abstract: Generating an image signal comprises a receiver (401) receiving source images representing a scene. A combined image generator (403) generates combined images from the source images. Each combined image is derived from only parts of at least two images of the source images. An evaluator (405) determines prediction quality measures for elements of the source images where the prediction quality measure for an element of a first source image is indicative of a difference between pixel values in the first source image and predicted pixel values for pixels in the element. The predicted pixel values are pixel values resulting from prediction of pixels from the combined images. A determiner (407) determines segments of the source images comprising elements for which the prediction quality measure is indicative of a difference above a threshold. An image signal generator (409) generates an image signal comprising image data representing the combined images and the segments of the source images.

Abstract: A method of generating an image signal from a plurality of images of a scene performs iterations that comprise generating (505) predicted images for a candidate set of images from a set of (previously) included images. A set of selected images is selected (509) from the set of candidate images in response to a prediction quality. For each selected image a subset of pixels is determined (511) in response to pixel prediction qualities for the pixels of the image, and a set of partial images corresponding to the selected images is generated (513) by selecting (511) a subset of pixels. The selected image is deleted from the candidate set and the partial image is added to the included set. The approach may provide a low complexity and low resource selection of image data representing a scene.

Abstract: An apparatus comprises a receiver (301) for receiving an image representation of a scene. A determiner (305) determines viewer poses for a viewer with respect to a viewer coordinate system. An aligner (307) aligns a scene coordinate system with the viewer coordinate system by aligning a scene reference position with a viewer reference position in the viewer coordinate system. A renderer (303) renders view images for different viewer poses in response to the image representation and the alignment of the scene coordinate system with the viewer coordinate system. An offset processor (309) determines the viewer reference position in response to an alignment viewer pose where the viewer reference position is dependent on an orientation of the alignment viewer pose and has an offset with respect to a viewer eye position for the alignment viewer pose. The offset includes an offset component in a direction opposite to a view direction of the viewer eye position.

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 display comprises a pixelated display panel comprising an array of single color pixels or an array of sub-pixels of different colors and a view forming arrangement comprising an array of lens elements. The pixels form a hexagonal grid, and the lenses also repeat in a hexagonal grid. A vector p is defined which relates to a mapping between the pixel grid and the lens grid. Regions in the two dimensional space for this vector p are identified which give good or poor banding performance, and the better banding performance regions are selected.

Abstract: The invention provides a multi-view display in which a view forming arrangement comprises a first view forming structure spaced by a first distance from the display panel for providing multiple views across a first direction, and a second view forming arrangement spaced by a second distance from the display panel for providing multiple views across a second perpendicular direction. The angular width of the multiple views in the two directions can thus be independently defined.
