  • Patent number: 11039133
    Abstract: A filter processing section 352 performs a filter process for applying an offset to pixels of a decoded image. A filter controller 351 inhibits the offset from being applied to an edge portion depending on occurrence of a transform unit in a transformation skip mode in which orthogonal transformation is not performed on a predicted residual. Furthermore, the filter controller 351 determines whether an offset for gradation adjustment using the decoded image is to be applied in the filter processing section 352 or not, and sets an offset in case the offset is to be applied. It is possible to make less conspicuous in the boundary between a transform unit where orthogonal transformation is performed by the offset for gradation adjustment and the transform unit where orthogonal transformation is skipped. The image quality of the decoded image is restrained from being lowered.

  • Patent number: 11025917
    Abstract: Aspects of the disclosure provide method and apparatus for video coding. In some examples, an apparatus includes processing circuitry for video decoding. The processing circuitry calculates cost function values for refined block vector positions. The refined bock vector positions are determined based on a position of a block vector predictor for a block vector of a current block in a picture. The processing circuitry determines a refined block vector predictor for the block vector of the current block based on the refined block vector position that has a smallest cost function value among the cost function values. Further, the processing circuitry reconstructs at least one sample of the current block based on the refined block vector predictor.

  • Patent number: 11012713
    Abstract: A system comprises an encoder configured to compress attribute information and/or spatial information for a point cloud and/or a decoder configured to decompress compressed attribute and/or spatial information for the point cloud. To compress the attribute and/or spatial information, the encoder is configured to convert a point cloud into an image based representation. Also, the decoder is configured to generate a decompressed point cloud based on an image based representation of a point cloud. In some embodiments, a bit stream structure may be used to communicate compressed point cloud data. The bit stream structure may include point cloud compression network abstraction layer (PCCNAL) units that enable use of groups of frames (GOFs), frame, and sub-frame signaling of patch information. Such a bit stream structure may permit low delay streaming and random access reconstruction of point clouds amongst other applications.

  • Patent number: 11004226
    Abstract: A stereo image capturing device captures a stereo image with a measurement target range in front of a vehicle as an angle of field, and a display device is disposed so as to cover at least part of the measurement target range as seen from the viewpoint position of a driver inside the vehicle. Then a distance measuring section measures the distances to another object in the measurement target range using the stereo image and identifies the object within a predetermined distance as an obstacle, and an image generating section generates a virtual mirror image that allows at least the vehicle and the obstacle to be seen using a reflection by a mirror in a case where the mirror is assumed to be virtually disposed above a location at which the obstacle is seen from the viewpoint position of the driver in the vehicle, and causes the display device to display the virtual mirror image. The present technology can be applied, for example, to in-vehicle image display systems.

  • Patent number: 10958936
    Abstract: To increase efficiency of a bit-depth scalable data-stream an inter-layer prediction is obtained by mapping samples of the representation of the picture or video source data with a first picture sample bit-depth from a first dynamic range corresponding to the first picture sample bit-depth to a second dynamic range greater than the first dynamic range and corresponding to a second picture sample bit-depth being higher than the first picture sample bit-depth by use of one or more global mapping functions being constant within the picture or video source data or varying at a first granularity, and a local mapping function locally modifying the one or more global mapping functions and varying at a second granularity smaller than the first granularity, with forming the quality-scalable data-stream based on the local mapping function such that the local mapping function is derivable from the quality-scalable data-stream.
