US 7826532 B2Abstract
MVCy=MVy when a reference source field and a reference destination field are both a top field or are both a bottom field,
( MVC3_x , MVC3_y ) = ( MV_x / 2 , MV_y / 2 - 1 / 4 ) = ( 0 / 2 , 1 / 2 - 1 / 4 ) = ( 0 , 1 / 4 ) ( 12 ) Then, this value is outputted as the chrominance motion vector 242 shown in FIG. 19. If this vector (0,¼) is applied to the top coding field chrominance pixel 162, a bottom reference field chrominance pixel position 163 is used as a predicted value. In FIG. 20, the vertical positional relation between pixels corresponds to a real pixel. As is clear from FIG. 20, a luminance motion vector (0,1) and a chrominance motion vector (0,1/4) are parallel. Thus, the color deviation between luminance and chrominance components, which is a conventional problem, can be solved by the present invention.
( MVC2_x , MVC2_y ) = ( MV_x / 2 , MV_y / 2 + 1 / 4 ) = ( 0 / 2 , 1 / 2 + 1 / 4 ) = ( 0 , 3 / 4 ) ( 13 ) Then, this value is outputted as the chrominance motion vector 242 shown in FIG. 19. If this vector (0, ¾) is applied to the bottom coding field chrominance pixel 172, a top reference field chrominance pixel position 173 is used as a predictive position. In FIG. 21, the vertical positional relation between pixels corresponds to a real one. As is clear from FIG. 21, a luminance motion vector (0,1) and a chrominance motion vector (0, ¾) are parallel. Thus, the color deviation between luminance and chrominance components, which is a conventional problem, can be solved by the present invention.
