Correlation detectors 21 and 22 employ two different correlation detecting methods to determine correlations. Correlation comparators 23 and 24 output correlation values DF1 and DF2, and motion vectors MV1 and MV2 in directions representing largest correlation values. A correlation comparator 25 selects one of the motion vectors larger in correlation, as a motion vector MV3, to output an interpolation control signal FS1 to determine an interpolation method at an interpolator 3. The interpolator 3 is operative in accordance with the interpolation control signal FS1, to select any one out of two different one-side interpolations and a both-side interpolation, to generate interpolation pixel data fp0.
