Publication number: 20210235093Abstract: Video processing techniques and pipelines that support capture, distribution, and display of high dynamic range (HDR) image data to both HDR-enabled display devices and display devices that do not support HDR imaging. A sensor pipeline may generate standard dynamic range (SDR) data from HDR data captured by a sensor using tone mapping, for example local tone mapping. Information used to generate the SDR data may be provided to a display pipeline as metadata with the generated SDR data. If a target display does not support HDR imaging, the SDR data may be directly rendered by the display pipeline. If the target display does support HDR imaging, then an inverse mapping technique may be applied to the SDR data according to the metadata to render HDR data for display. Information used in performing color gamut mapping may also be provided in the metadata and used to recover clipped colors for display.Type: ApplicationFiled: April 16, 2021Publication date: July 29, 2021Inventors: Haitao Guo, Hao Pan, Guy Cote, Andrew Bai

Publication number: 20210227226Abstract: Adaptive video processing for a target display panel may be implemented in or by a server/encoding pipeline. The adaptive video processing methods may obtain and take into account video content and display panel-specific information including display characteristics and environmental conditions (e.g., ambient lighting and viewer location) when processing and encoding video content to be streamed to the target display panel in an ambient setting or environment. The server-side adaptive video processing methods may use this information to adjust one or more video processing functions as applied to the video data to generate video content in the color gamut and dynamic range of the target display panel that is adapted to the display panel characteristics and ambient viewing conditions.Type: ApplicationFiled: December 23, 2020Publication date: July 22, 2021Applicant: Apple Inc.Inventors: Kenneth I.

Patent number: 10271054Abstract: Adaptive video processing for a target display panel may be implemented in or by a decoding/display pipeline associated with the target display panel. The adaptive video processing methods may take into account video content, display characteristics, and environmental conditions including but not limited to ambient lighting and viewer location when processing and rendering video content for a target display panel in an ambient setting or environment. The display-side adaptive video processing methods may use this information to adjust one or more video processing functions as applied to the video data to render video for the target display panel that is adapted to the display panel according to the ambient viewing conditions.Type: GrantFiled: February 25, 2015Date of Patent: April 23, 2019Assignee: Apple, Inc.Inventors: Kenneth I.
