摘要： A method of performing motion vector prediction for coding video data is disclosed. A motion vector is received. A mask information based on the motion vector is derived. A round information based on the motion vector is derived. A rounded motion vector is derived by masking a value, obtained by adding the round information to the motion vector, based on the mask information. A collocated motion vector based on the rounded motion vector is generated.

摘要： The present invention reduces the amount of storage required for CCLM prediction. A CCLM prediction parameter derivation portion (310442) derives a scale shift value corresponding to a luminance difference value, and uses the scale shift value to shift a value acquired by multiplying a value of a table by a chrominance difference value, thereby deriving CCLM prediction parameters. The value of the table refers to, as an index, a value acquired by right-shifting the luminance difference value by the scale shift value. Further, during derivation of a prediction image, a bit width is reduced by adaptively deriving the amount of shift of a linear prediction parameter from the chrominance difference value.
