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: 10055816Abstract: A pair of cameras having an overlapping field of view is aligned based on images captured by image sensors of the pair of cameras. A pixel shift is identified between the images. Based on the identified pixel shift, a calibration is applied to one or both of the pair of cameras. To determine the pixel shift, the camera applies correlation methods including edge matching. Calibrating the pair of cameras may include adjusting a read window on an image sensor. The pixel shift can also be used to determine a time lag, which can be used to synchronize subsequent image captures.Type: GrantFiled: September 21, 2017Date of Patent: August 21, 2018Assignee: GoPro, Inc.Inventors: Yajie Sun, Timothy Macmillan, Elizabeth Torres Edwards, Sumit Chawla

Patent number: 9648293Abstract: The conversion of RAW data captured by a camera can have artifacts in smoothness of various hues for varying chroma. To optimize smoothness and color accuracy, transform coefficients defining conversion of a standard color model to a target color model are determined. The RAW data is converted to data in a standard color model and the data in the standard color model is converted to data in the target color model using the transform coefficients. The process is repeated for various lightness levels and combined into a look up table to efficiently convert RAW data to data in the target color model for various lightness levels.Type: GrantFiled: October 22, 2014Date of Patent: May 9, 2017Assignee: GOPRO, INC.Inventors: Sumit Chawla, Elizabeth Torres Edwards, Ying Chen
