Patent number: 11711613Abstract: Image frames for computational photography may be corrected, such as through rolling shutter correction (RSC), prior to fusion of the image frames to reduce wobble and jitter artifacts present in a video sequence of HDR-enhanced image frames. First and second motion data regarding motion of the image capture device may be determined for times corresponding to the capturing of the first and second image frames, respectively. The rolling shutter correction (RSC) may be applied to the first and second image frames based on both the first and second motion data. The corrected first and second image frames may then be aligned and fused to obtain a single output image frame with higher dynamic range than either of the first or second image frames.Type: GrantFiled: April 27, 2021Date of Patent: July 25, 2023Assignee: QUALCOMM IncorporatedInventors: Shang-Chih Chuang, Ron Gaizman, Pradeep Veeramalla, Shizhong Liu, Weiliang Liu, Xiaoyun Jiang, Narayana Karthik Ravirala, Jiafu Luo, Srinath Anekere Narayan, Wei Zou

Patent number: 11706416Abstract: An image decoding apparatus obtain pieces of coded data that is included in a bitstream and generated by coding tiles. Tile boundary independence information is further obtained from the bitstream, with the tile boundary independence information indicating whether each of boundaries between the tiles is one of a first boundary or a second boundary. The pieces of coded data are decoded to generate image data of the tiles. Image data of a first tile is generated by decoding a first code string included in first coded data with reference to decoding information of a decoded tile when the tile boundary independence information indicates the first boundary, and by decoding the first code string without referring to the decoding information of the decoded tile when the tile boundary independence information indicates the second boundary.Type: GrantFiled: December 2, 2021Date of Patent: July 18, 2023Assignee: SUN PATENT TRUSTInventors: Daisaku Komiya, Takahiro Nishi, Youji Shibahara, Hisao Sasai, Toshiyasu Sugio, Kyoko Tanikawa, Toru Matsunobu

Patent number: 11689457Abstract: A label switching router for a switching network configured for source routing can be configured to modify one or more reported properties of a link associated with that router based on one or more link quality metrics. For example, a router can include a link with available bandwidth of 10 Gbps, a value that can be used by a headend when evaluating nodes of the network against a set of constraints required by a particular requested connection or tunnel. A link of that router may exhibit an increased bit error rate which can be used by the label switching router to artificially deflate available bandwidth, thereby reducing the number of label switching paths including the router are selected by the headend.Type: GrantFiled: January 14, 2022Date of Patent: June 27, 2023Assignee: T-MOBILE USA, INC.Inventor: Cameron Byrne

Patent number: 11689598Abstract: Techniques for synchronized out-of-order live video encoding are described. As one example, a computer-implemented method includes receiving a first real-time encoded live video, that is in a coded order that is different than a display order, at a content delivery service from a contribution encoder at a different location than the content delivery service, performing, in the coded order, a real-time decode of the first real-time encoded live video by a distribution decoder of the content delivery service to generate a decoded video in the coded order, performing, in the coded order, a real-time encode of the decoded video by a distribution encoder of the content delivery service to generate a second real-time encoded video in the coded order without waiting on a reordering of the decoded video into the display order, and transmitting the second real-time encoded video in the coded order to a client device.Type: GrantFiled: March 17, 2021Date of Patent: June 27, 2023Assignee: Amazon Technologies, Inc.Inventor: Charles Benjamin Waggoner
