摘要： A first motion vector points from a source region of a source picture to a destination region of a destination picture. A second motion vector is scaled from the first motion vector based on a first temporal distance between the source picture and the interpolation picture. A third motion vector is scaled from the first motion vector based on a second temporal distance between the destination picture and the interpolation picture. A weight of a first interpolation region of the interpolation picture is calculated using distortion energy of the source region. A first motion compensation picture compensated from the source region to a temporal position of the interpolation picture using the second motion vector, and a second motion compensation picture compensated from the destination region to the temporal position using the third motion vector are calculated. A third motion compensation picture is calculated by weighted-averaging the first motion compensation picture and the second motion compensation picture. A second interpolation region of the interpolation picture is calculated by averaging a region of the third motion compensation picture and a region of an artifact prevention picture with the weight.

摘要： An estimation unit calculates an estimated motion vector between a first source region of a plurality of source regions and a first destination region on a destination picture. The first destination region has the highest correlation with the first source region. A weight calculation unit searches a plurality of second destination regions. Each second destination region is pointed by the estimated motion vector of another source region adjacent to the first source region. The weight calculation unit extracts pixel values of each second destination region, calculates a difference of pixel values between the first source region and each second destination region, and calculates a weight based on the difference. The weight is smaller if the difference is larger. A filtering unit calculates a motion vector of the first source region by averaging the estimated motion vectors with the weight.
