  • Patent number: 11095877
    Abstract: Innovations in motion estimation adapted for screen remoting scenarios are described. For example, a video encoder calculates a hash value for a current block in a current picture. The video encoder searches, subject to a spatial constraint, for a matching block in a reference picture (e.g., the previous picture in display order) based at least in part on the hash value for the current block. The spatial constraint defines a search area in the reference picture within which hash values for candidate blocks in the reference picture may be compared to the hash value for the current block. By using a spatial constraint to limit the range of the local hash-based motion estimation, the video encoder can speed up the motion estimation process while still considering the candidate blocks in the reference picture that are most likely to match the current block.

  • Patent number: 11080863
    Abstract: An imaging apparatus includes a photometric sensor, and can continuously acquire a plurality of images by a single imaging operation. A CPU for image processing and an arithmetic operation acquires image data output by a photometric sensor and performs photometric processing. The CPU determines presence or absence of a flicker light source using a plurality of pieces of acquired image data, and calculates a motion vector of an object by comparison of image data. If it is determined that there is a flicker light source in a photographing environment, gain adjustment is performed on the basis of a result of flicker detection so as to have a brightness of an image suitable for detection of a motion vector, and the motion vector is calculated using image data after gain adjustment.

  • Patent number: 11070838
    Abstract: Extra precision can be added to motion vectors, such as those obtained using advanced motion vector prediction or frame rate upconversion, to produce improved motion compensation. The increased precision from neighboring blocks are used to provide increased precision to a motion vector for a current block.

  • Patent number: 11057617
    Abstract: Aspects of the disclosure provide a method and an apparatus for video coding. In some examples, the apparatus includes processing circuitry. The processing circuitry decodes prediction information of a current block in a current picture from a coded video bitstream and the prediction information is indicative of inter prediction. The processing circuitry determines, for the current block, motion information including a first motion vector (MV) that has a x component and a y component where each of the x and y components has a fractional MV precision that is 2?N of a sample size in the current block and has one of 2L+1 MV values with the fractional MV precision. N is an integer larger than 2 and L is a positive integer. The processing circuitry reconstructs at least one sample of the current block based on the motion information.
