Publication number: 20240098320Abstract: 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.Type: ApplicationFiled: October 26, 2023Publication date: March 21, 2024Applicant: Microsoft Technology Licensing, LLCInventors: Yongjun Wu, Naveen Thumpudi, Shyam Sadhwani

Publication number: 20240005452Abstract: The techniques disclosed herein enable systems to perform automatic camera rotation for multi-posture devices (e.g., tablet devices, foldable devices, external displays with built-in webcams) irrespective of a current posture of the computing device. This is accomplished by reformatting an image captured by an image sensor using an image signal processer prior to encoding for output. To reformat the image, the computing device determines an angle of rotation for the computing device relative to a default posture. The image is then rotated based on the angle of rotation such that the image appears right side up for the current posture. Subsequently, the image is cropped from its original aspect ratio to a predetermined aspect ratio. Finally, the image is encoded to generate an output stream that can be received by an application. In this way, the system maintains visual consistency even as a user rotates the device.Type: ApplicationFiled: June 29, 2022Publication date: January 4, 2024Inventors: Michael Jeffrey AJAX, Naveen THUMPUDI, Gerrit Lance SWANEVELD, Sang Kun CHOE

Patent number: 10841494Abstract: 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.Type: GrantFiled: April 3, 2019Date of Patent: November 17, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Yongjun Wu, Nikola Borisov, Weidong Zhao, Shyam Sadhwani, Naveen Thumpudi
