  • Publication number: 20210377578
    Abstract: A media processing tool adds custom data to an elementary media bitstream or media container. The custom data indicates nominal range of samples of media content, but the meaning of the custom data is not defined in the codec format or media container format. For example, the custom data indicates the nominal range is full range or limited range. For playback, a media processing tool parses the custom data and determines an indication of media content type. A rendering engine performs color conversion operations whose logic changes based at least in part on the media content type. In this way, a codec format or media container format can in effect be extended to support full nominal range media content as well as limited nominal range media content, and hence preserve full or correct color fidelity, while maintaining backward compatibility and conformance with the codec format or media container format.

  • Patent number: 11094030
    Abstract: An image sensor is misaligned with an operating orientation. Misalignment information may be registered with an operating system. Misaligned image data may be transformed as a final processing act before being delivered to an application. A method of transforming image misalignment. Image data having a first orientation is received from an image sensor at a first computing component of a computing device. The image data is transformed using misalignment information to transformed image data having a second orientation. Immediately after transforming the image data, the transformed image data is communicated from a final computing component to an application.

  • Patent number: 10841494
    Abstract: Video image stabilization provides better performance on a generic platform for computing devices by evaluating available multimedia digital signal processing components, and selecting the available components to utilize according to a hierarchy structure for video stabilization performance for processing parts of the video stabilization. The video stabilization has improved motion vector estimation that employs refinement motion vector searching according to a pyramid block structure relationship starting from a downsampled resolution version of the video frames. The video stabilization also improves global motion transform estimation by performing a random sample consensus approach for processing the local motion vectors, and selection criteria for motion vector reliability. The video stabilization achieves the removal of hand shakiness smoothly by real-time one-pass or off-line two-pass temporal smoothing with error detection and correction.

  • Publication number: 20190236035
    Abstract: A system for camera device command and control detects a camera device connected to the system and accesses a set of interfaces defined by a standardized driver. The set of interfaces are a common set of interfaces associated with a device object and the device object is compatible with camera devices from different camera device manufacturers. The system queries the detected camera device for descriptors defining capabilities of the camera device using a packetized command generated based at least on the accessed set of interfaces and provides, based on the descriptors, one or more interfaces of the accessed set of interfaces to one or more applications to make the camera device available to the one or more applications, thereby simplifying connection of camera devices from different manufacturers and improving the user experience. The system then allows the camera device to be controlled.
