Claim 3:
4. The motion vector generation apparatus according to claim 2, wherein the first parameter generation process includes a first parameter smoothing process in which the processing circuitry smooths a first parameter λ′(t0) of a current frame that has been smoothed in a spatial direction in a temporal direction using a first parameter λ″(t0−1) of an immediately previous frame that has been smoothed in spatial and temporal directions and a first value, based on a magnitude relationship between the first value and a difference between the first parameter λ″(t0−1) and the first parameter λ′(t0), and
the second parameter generation process includes a second parameter smoothing process in which the processing circuitry smooths a second parameter λ′2(t0) of the current frame that has been smoothed in the spatial direction in the temporal direction using a second parameter λ″2(t0−1) of the immediately previous frame that has been smoothed in the spatial and temporal directions and a second value, based on a magnitude relationship between the second value and a difference between the second parameter λ″2(t0−1) and the second parameter λ′2(t0).
