  • Patent number: 10291939
    Abstract: When carrying out an intra-frame prediction process to generate an intra prediction image by using an already-encoded image signal in a frame, an intra prediction part 4 selects a filter from one or more filters which are prepared in advance according to the states of various parameters associated with the encoding of a target block to be filtered, and carries out a filtering process on a prediction image by using the filter. As a result, prediction errors which occur locally can be reduced, and the image quality can be improved.

  • Publication number: 20190124328
    Abstract: When carrying out an average prediction, an intra predictor carries out a filtering process on target pixels of the intra prediction located at an upper end and a left end of the block, the filtering process using an intermediate prediction value, which is an average value of adjacent pixels of the block, and at least one adjacent pixel of the target pixel. The intra predictor also sets a filter coefficient to ¾, associated with the intermediate prediction value for a target pixel at the left end of the block other than the target pixel at an upper left corner of the block, and sets a filter coefficient to ¼, associated with the adjacent pixel adjacent to the left side of the target pixel at the left end of the block. As a result, prediction errors locally occurring can be reduced, and the image quality can be improved.

  • Patent number: 10264289
    Abstract: Since time hierarchically encoded video data needs to include video data of a basic hierarchical layer, and video data cannot be generated in which a frame belonging to an upper hierarchical layer is only encoded, even in a case in which only a part of frames is processed, a basic hierarchical layer frame is needed to be included, and thus, there has been a problem that video data in which only the frame belonging to the upper hierarchical layer is encoded cannot be separately processed. In the present invention, a variable length encoding unit is disposed which encodes, for each sequence, a basic hierarchical layer existence flag showing whether or not a basic hierarchical layer is included in the sequence.
