High dynamic range video capture with backward-compatible distribution
10212429 · 2019-02-19 · ·

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.

Color metadata for a downlink data channel

The present invention provides a method and system for determining and providing color metadata for a downlink data channel. In accordance with the present invention color metadata is determined such that gamut mapping is defined by a transmitted source gamut which enables adapted mapping that preserves saturation and contrast levels of the source for a downlink data channel. The metadata is then provided to a downlink data channel for color management.

PROJECTOR DISPLAY CALIBRATION

Embodiments describing an approach to generating, a calibration slide for a presentation. Receiving, a first image of the calibration slide. Receiving, a second image of the calibration slide, wherein the second image of the calibration slide is associated with the projector component. Analyzing, the first image of the calibration slide and the second image of the calibration slide, wherein the analysis comprises: comparing, display attributes between the first and second image of the calibration slide, and identifying, distortions in the second image of the calibration slide. Responsive to the analysis, calibrating, the display attributes of the presentation based on a preset user threshold of acceptance.

Provided is an information processing apparatus including an acquisition unit that acquires a second image obtained by photographing a color sample by a second camera device and by developing, and an estimation unit that estimates a second 3D-LUT for reproducing, by the first camera device, a color of the color sample in the second image by inputting the second image to a model that has learned a first image obtained by photographing the color sample under a standard light source by a first camera device and by developing as input data and a first 3D lookup table (3D-LUT) used for developing the first image as correct answer data. As a result, the 3D-LUT can be generated more easily.

Tracking details of activation of licensable component of consumer electronic device

Instead of buying blanket licenses for all licensable components of its CE devices, a manufacturer enables users to activate licensable components on a device basis and then obtains the necessary licenses individually. Seldom used activation modes and seldom activated licensable components can be pruned from future devices, while widely activated licensable components can be automatically enabled by purchasing a blanket license for those components. Characteristics of license requests and the people making them can be used to focus marketing.

Devices, systems, and methods for instant video switching in an extension environment

Extension devices such as upstream facing port devices (UFP devices) and downstream facing port devices (DFP devices) connect via an extension medium. When a UFP device and a DFP device pair with each other, DisplayPort video and/or audio information from a DisplayPort source device can be presented by a DisplayPort sink device, which are coupled to the UFP device and DFP device, respectively. In some embodiments, the DFP device may train a DisplayPort link to the DisplayPort sink device regardless of whether it is receiving actual data from a UFP device, and may provide placeholder data to the DisplayPort sink device in order to keep the link active. The DFP device may then replace the placeholder data with the actual data from the UFP device, once received, and may thereby seamlessly switch the DisplayPort sink device from presenting placeholder data to presenting data from the DisplayPort source device.

Display with an appropriate luminance dynamic range is realizable on a receiving side. A gamma curve is applied to input video data having a level range from 0% to 100%*N (N: a number larger than 1) to obtain transmission video data. This transmission video data is transmitted together with auxiliary information used for converting a high-luminance level on the receiving side. A high-level side level range of the transmission video data is converted on the receiving side such that a maximum level becomes a predetermined level based on the auxiliary information received together with the transmission video data.

Activating licensable component using aggregating device in home network

An aggregation device in a home network accumulates information from audio video apparatuses in the network that the apparatuses require enablement of respective licensable components for which no license event has yet occurred. The aggregation device sends an indication of the license events to a server so that appropriate royalties may be paid post-sale of the various devices.
