Publication number: 20240129636Abstract: Visual content that includes spatial portions is obtained. A determination is made that one of the spatial portions includes a face. Based on the determination, encoding quality parameters for the one of the spatial portions is identified. The encoding quality parameters are obtained by combining a first distortion model related to the obtaining the visual content with a second model that emphasizes the one of the spatial portions The visual content is encoded. The encoding quality parameters are stored, in association with but separate from, the one of the spatial portions. After decoding, the one of the spatial portions are rendered based on the encoding quality parameters. The encoding quality parameters are obtained by combining a first distortion model related to the obtaining the visual content with a second model that emphasizes the one of the spatial portions.Type: ApplicationFiled: April 20, 2023Publication date: April 18, 2024Applicant: GoPro, Inc.Inventors: Balineedu Chowdary Adsumilli, Adeel Abbas, Sumit Chawla

Publication number: 20230412754Abstract: A camera system captures an image in a source aspect ratio and applies a transformation to the input image to scale and warp the input image to generate an output image having a target aspect ratio different than the source aspect ratio. The output image has the same field of view as the input image, maintains image resolution, and limits distortion to levels that do not substantially affect the viewing experience. In one embodiment, the output image is non-linearly warped relative to the input image such that a distortion in the output image relative to the input image is greater in a corner region of the output image than a center region of the output image.Type: ApplicationFiled: August 3, 2023Publication date: December 21, 2023Inventors: Nicholas D. Woodman, Sumit Chawla, Loic Segapelli, Scott Patrick Campbell

Publication number: 20220311922Abstract: Systems and methods are provided that capture and process frames of frame data. An image sensor captures frames of frame data representative of light incident upon the image sensor using a rolling shutter and outputs the frames of frame data. The image sensor captures at least one of the frames over a frame capture interval and then waits over a blanking interval before capturing another frame. A buffer receives and stores the frames output by the image sensor. An image signal processor retrieves the frames from the buffer and processes the frames over successive frame processing intervals to generate a video having a time interval per frame greater than the frame capture interval. At least one of the successive frame processing intervals is greater than the frame capture interval and is less than or equal to a sum of the frame capture interval and the blanking interval.Type: ApplicationFiled: June 8, 2022Publication date: September 29, 2022Inventors: Paul Mobbs, Scott Patrick Campbell, David A.

Patent number: 10535125Abstract: The processing of RGB image data can be optimized by performing optimization operations on the image data when it is converted into the YCbCr color space. For each Y-layer of the YCbCr image data, a 2D LUT is generated. The YCbCr image data is converted into optimized CbCr image data using the 2D LUTs, and optimized YCbCr image data is generated by blending CbCr image data corresponding to multiple Y-layers. The optimized YCbCr image data is converted into sRGB image data, and a tone curve is applied to the sRGB image data to produce optimized sRGB image data.Type: GrantFiled: March 21, 2018Date of Patent: January 14, 2020Assignee: GoPro, Inc.Inventors: Ying Chen, Sumit Chawla, Elizabeth Torres Edwards, Kartheek Chandu, Bo Ding

Patent number: 10536715Abstract: Systems and methods for utilizing on-camera sensor information to improve video and/or image encoding quality are discussed herein. Specifically, the systems and methods may utilize on-camera sensor information to efficiently determine whether to encode a particular frame within a set of frames as an intra frame. When captured on video, a particular arrangement of a group of pixels within a frame may comprise a visual representation of an object within the frame. When encoding video footage, motion information characterizing motion of an image capturing device over time may be used to predict displacement of an arrangement of group of pixels between frames. These predictions may be used to efficiently determine whether to encode a particular frame as an intra frame.Type: GrantFiled: March 17, 2017Date of Patent: January 14, 2020Assignee: GoPro, Inc.Inventors: Sandeep Doshi, Sumit Chawla, Adeel Abbas

Publication number: 20190289322Abstract: Systems and methods for utilizing on-camera sensor information to improve video and/or image encoding quality are discussed herein. Specifically, the systems and methods described herein may utilize on-camera sensor information to adaptively adjust an intra frame insertion rate associated with a sequence of frames. The intra frame insertion rate associated with a sequence of frames may be adjusted based on the motion of the image capturing device while capturing the sequence of frames and a predefined motion threshold associated with the intra frame insertion rate of the sequence of frames. In some implementations, the intra frame insertion rate may be adjusted based on the activity being performed during the capture of the sequence of frames. As such, the encoding of one or more frames within a sequence of frames may be adaptively adjusted to better suit the scene depicted by the sequence of frames.Type: ApplicationFiled: March 17, 2017Publication date: September 19, 2019Inventors: Adeel Abbas, Sandeep Doshi, Sumit Chawla
