  • Patent number: 12003777
    Abstract: A mechanism for processing video data is disclosed. Video decoder initialization information (DII) is determined. The DII includes data describing a maximum level (MaxLevel) to which all coded video sequences (CVSs) of the bitstream conform and a maximum format that comprises one or more parameters. The MaxLevel indicates a first maximum DPB size needed for decoding the bitstream. The maximum format indicates a second maximum DPB size, denoted as DPB memory for as maximum format (DpbMemory4MaxFormat), determined by simultaneously setting all parameters of the maximum format to largest values. The DII further comprises a first indication of whether the DpbMemory4MaxFormat exceeds the first maximum DPB size. A conversion is performed between a visual media data and a bitstream based on the indication.

  • Patent number: 11985431
    Abstract: An imaging system may include an electronic shutter. The electronic shutter may be positioned between an image sensor and a lens module or may be integrated as a package cover for the image sensor. The electronic shutter may selectively attenuate incident light that passes to the image sensor. To increase the dynamic range of the imaging system, the electronic shutter may have a first transparency while a first image is captured by the image sensor and a second, different transparency while a second image is captured by the image sensor. The first and second images are subsequently combined to form a single high dynamic range image. The electronic shutter may be controlled at a global level, at a sub-array level, or at a pixel level.
