    Abstract: An image synthesis apparatus comprises a first receiver (201) receiving three dimensional image data describing at least part of a three dimensional scene and second receiver (203) receiving a view pose for a viewer. An image region circuit (207) determines at least a first image region in the three dimensional image data and a depth circuit (209) determines a depth indication for the first image region from depth data of the three dimensional image data. A region circuit (211) determines a first region for the first image region. A view synthesis circuit (205) generates a view image from the three dimensional image data where the view image representing a view of the three dimensional scene from the view pose. The view synthesis circuit (205) is arranged to adapt a transparency for the first image region in the view image in response to the depth indication and a distance between the view pose and the first region.

    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: Concepts for encoding and decoding multi-view data for immersive video are disclosed. In an encoding method, metadata is generated comprising a field indicating if a patch data unit of the multi-view data comprises in-painted data for representing missing data. The generated metadata provides a means of distinguishing patch data units comprising original texture and depth data from patch data units comprising in-painted data (e.g. in-painted texture and depth data). The provision of such information within the metadata of immersive video may address problems associated with blending and pruned view reconstruction. Also provided are an encoder and a decoder for multi-view data for immersive video, and a corresponding bitstream, comprising metadata.

    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: An autostereoscopic display device uses an electroluminescent display. A set of pixels is provided beneath view forming elements (such as lenses), with a plurality of pixels across the view forming element width direction. The pixels are arranged with at least two different angular orientations with respect to the substrate. The out-coupling performance is improved by arranging for the light emission direction to be substantially perpendicular to the desired emitting surface of the view forming elements.

    Abstract: The present invention relates to an ultrasound apparatus for medical examination of a subject. The ultrasound apparatus comprises a plurality of ultrasound transducers for emitting and receiving ultrasound waves and for providing different ultrasound signals on the basis of the ultrasound waves. A connection layer is provided, which is attachable to the subject, wherein the ultrasound transducers are coupled to the connection layer. A processing unit, which is connectable to the ultrasound transducers is provided for receiving the ultrasound signals and for determining at least one parameter on the basis of the ultrasound signals. The processing unit is adapted to determine at least one parameter indicative of a relative position of the ultrasound transducers to each other and/or a shape of the connection layer and the ultrasound waves are surface acoustic waves transmitted through the connection layer or a layer attached to the connection layer.
