  • Publication number: 20200202814
    Abstract: One or more media contents are received. A viewer's light adaptive states are predicted as a function of time as if the viewer is watching display mapped images derived from the one or more media contents. The viewer's light adaptive states are used to detect an excessive change in luminance in a specific media content portion of the one or more media contents. The excessive change in luminance in the specific media content portion of the one or more media contents is caused to be reduced while the viewer is watching one or more corresponding display mapped images derived from the specific media content portion of the one or more media contents.

  • Publication number: 20200134780
    Abstract: Peripheral-vision expanded images are streamed to a video streaming client. The peripheral-vision expanded images are generated from source images in reference to view directions of the viewer at respective time points. View direction data is collected and received in real time while the viewer is viewing display images derived from the peripheral-vision expanded images. A second peripheral-vision expanded image is generated from a second source image in reference to a second view direction of the viewer at a second time point. The second peripheral-vision expanded image has a focal-vision image portion covering the second view direction of the viewer and a peripheral-vision image portion outside the focal-vision image portion. The second peripheral-vision expanded image is transmitted to the video streaming client.

  • Publication number: 20190261049
    Abstract: Novel systems and methods are described for creating, compressing, and distributing video or image content graded for a plurality of displays with different dynamic ranges. In implementations, the created content is “continuous dynamic range” (CDR) content—a novel representation of pixel-luminance as a function of display dynamic range. The creation of the CDR content includes grading a source content for a minimum dynamic range and a maximum dynamic range, and defining a luminance of each pixel of an image or video frame of the source content as a continuous function between the minimum and the maximum dynamic ranges. In additional implementations, a novel graphical user interface for creating and editing the CDR content is described.

  • Patent number: 10157318
    Abstract: A storyboard interface displaying key frames of a video may be presented to a user. Individual key frames may represent individual shots of the video. Shots may be grouped based on similarity. Key frames may be displayed in a chronological order of the corresponding shots. Key frames of grouped shots may be spatially correlated within the storyboard interface. For example, shots of a common group may be spatially correlated so that they may be easily discernable as a group even though the shots may not be temporally consecutive and/or or even temporally close to each other in the timeframe of the video itself.

  • Patent number: 10095953
    Abstract: Techniques of depth modification for display applications are disclosed. A multiscopic video frame, including at least first and second images depicting a scene, is received. Depth information pertaining to the multiscopic video frame is received. A depth mapping function is determined based on one or more image characteristics of the multiscopic video frame, other than depth. The depth information is modified based on the depth mapping function. At least a third image is generated based on the modified depth information and based further on at least one of the first and second images, where the third image is output for display.

  • Patent number: 9911202
    Abstract: Systems, methods, and computer program products to perform an operation comprising computing a saliency value for a video based on saliency values a set of pixels in each frame of the video, computing, for the video, an expected value for a metric by a predictive algorithm based on the saliency value for the video, and outputting the expected value for the metric as an indication of an expected outcome for the metric achieved by the video.
