  • Light projector using an acousto-optical control device
    Patent number: 10728532
    Abstract: An approach for projecting light may be implemented using a acousto-optical depth switch that uses surface acoustic waves produced along a substrate to guide image light to different areas. The surface acoustic waves may be generated on a substrate using a transducer. Surface acoustic waves of different frequencies can guide image light onto different optical elements at different physical positions. The optical elements may be configured to show objects in an image at different distances from a viewer.

  • Compatible stereoscopic video delivery
    Patent number: 10721453
    Abstract: Stereoscopic images are subsampled and placed in a “checkerboard” pattern in an image. The image is encoded in a monoscopic video format. The monoscopic video is transmitted to a device where the “checkerboard” is decoded. Portions of the checkerboard (e.g., “black” portions) are used to reconstruct one of the stereoscopic images and the other portion of the checkerboard (e.g., “white” portions) are used to reconstruct the other image. The subsamples are, for example, taken from the image in a location coincident to the checkerboard position in which the subsamples are encoded.

  • Method of and device for encoding an HDR video together with an LDR video, method of and device for reconstructing one of an HDR video and an LDR video coded together and non-transitory storage medium
    Patent number: 10708620
    Abstract: The inventors realized that representing HDR content using LDR content and HDR residual is not unproblematic. The invention therefore proposes representing HDR content using LDR content, LDR residual and global illumination data, instead. That is, it is proposed a method of encoding an HDR video of high dynamic range together with an LDR video, the LDR video providing a lower dynamic range depiction of the HDR video content, the method comprising using processing means for encoding one video of the LDR video and a further LDR video extracted from the HDR video independent from the other video of the LDR video and the HDR video and predictive encoding the other video using the one video as reference, and lossless encoding global illumination data further extracted from the HDR video. This has the advantage that prediction is more stable and globally optimal predictors are more easily found.
