Abstract:
First foviated images are streamed to a streaming client. The first foviated images with first image metadata sets are used to generate first display mapped images for rendering to a viewer at first time points. View direction data is collected and used to determine a second view direction of the viewer at a second time point. A second foviated image and a second image metadata set are generated from a second HDR source image in reference to the second view direction of the viewer and used to generate a second display mapped image for rendering to the viewer at the second time point. The second image metadata set comprises a display management metadata portions for adapting a focal-vision and peripheral-vision image portions to corresponding image portions in the second display mapped image. The focal-vision display management metadata portion is generated with a predicted light adaptation level of the viewer for the second time point. The second foviated image and the second image metadata set are transmitted to the video streaming client.
