Abstract:
A motion compensation method includes performing a motion compensation of a decoded image signal including a luma signal and a chroma signal in a format in which the number of chroma pixels is vertically different from the number of luma pixels. The method further includes detecting a condition that a reference field has a different parity from a current field for a motion compensation. The method further includes controlling, in the detected condition, the motion compensation so as to vertically shift a phase of the chroma signal in the reference field so that the reference field will coincide in phase of the chroma signal with a current field.
