Abstract: A method for merging graphics and high dynamic range video data is disclosed. In a video receiver, a display management process uses metadata to map input video data from a first dynamic range into the dynamic range of available graphics data. The remapped video signal is blended with the graphics data to generate a video composite signal. An inverse display management process uses the metadata to map the video composite signal to an output video signal with the first dynamic range. To alleviate perceptual tone-mapping jumps during video scene changes, a metadata transformer transforms the metadata to transformed so that on a television (TV) receiver metadata values transition smoothly between consecutive scenes. The TV receiver receives the output video signal and the transformed metadata to generate video data mapped to the dynamic range of the TV's display.

Abstract: Perceptually correct noises simulating a variety of noise patterns or textures may be applied to stereo image pairs each of which comprises a left eye (LE) image and a right eye (RE) image that represent a 3D image. LE and RE images may or may not be noise removed. Depth information of pixels in the LE and RE images may be computed from, or received with, the LE and RE images. Desired noise patterns are modulated onto the 3D image or scene so that the desired noise patterns are perceived to be part of 3D objects or image details, taking into account where the 3D objects or image details are on a z-axis perpendicular to an image rendering screen on which the LE and RE images are rendered.

Abstract: Several embodiments of a media processor for the creation of metadata from a set of images are given. The media processor receives a set of image data and computes metadata from the image data. The metadata may comprise statistical data based on the image data; from which the media processor may generate and store a multi-scale version of the metadata. The metadata may comprise statistical attributes derived directly from the image data or statistical attributes derived from image appearance correlates of the image data. The media processor may generate a subsampled set of the metadata and the subsampled set may be stored in an efficient data structure, such as a pyramidal structure. The pyramidal structure may be generated from spatial image information, from temporal image information or from spatial-temporal image information.

Abstract: A display apparatus, a display management module and a method for ambient light compensation are described. The display management module is configured to receive an input video signal comprising a sequence of video frames and to determine whether a current video frame of the sequence of video frames immediately follows a scene change. The display management module is further configured to adjust ambient light compensation applied to the input signal in dependence on the signal indicative of intensity of ambient light only in response to determining that the current video frame of the sequence of video frames immediately follows a scene change.

Abstract: An embodiment of the disclosure provides a method and a system to sense a light source based on a viewer position in relation to display device. The system receives sensor data from one or more light sensors mounted on a wearable device worn by a viewer of a display device in a room, where a field of view for the light sensors covers at least a field of view of the viewer. The system identifies a light source perceived in a field of view of the viewer based on the sensor data. The system transmits data for one or more operations to be performed by the display device displaying content to the viewer to compensate for a change in brightness or color of the content caused by the light source based at least in part on light source information of the light source.
