  • Patent number: 11197058
    Abstract: A method for handling video includes extracting video content and context information from a video file. The context information is associated with the video content. The method further includes transmitting the video content via a first communication path and transmitting the context information via a second communication path separate from the first communication path.
    Type: Grant
    Filed: November 7, 2018
    Date of Patent: December 7, 2021

  • Patent number: 9858644
    Abstract: The present disclose provides a Bayer color filter array based high dynamic range video recording method and device. The method includes configuring different photosensitive times for exposure according to odd-numbered dual columns and even-numbered dual columns, and obtaining an image frame with different exposure values of the odd-numbered dual columns and even-numbered dual columns; decomposing the image frame into an underexposure image frame and an overexposure image frame, where underexposure dual columns and missing dual columns are alternatingly distributed in the underexposure image frame, and overexposure dual columns and missing dual columns are alternatingly distributed in the overexposure image frame. The method also includes acquiring recovered pixel values of pixel points of the missing dual columns in the underexposure image frame and the overexposure image frame; and merging the overexposure image frame and the underexposure image frame to obtain a high dynamic range frame.
