Claim 4:
5. The motion vector generation apparatus according to claim 1, wherein the processing circuitry configured to:
execute NP pieces of nth parameter generation processes, where NP is an integer of 3 or more;
execute NP pieces of nth motion vector combining processes; and
execute a non-rigid vector extraction process in which the processing circuitry extracts NP bandpass components included in a difference between the motion vector and a reduced motion vector that is a motion vector scaled using the first parameter,
wherein in the second parameter generation process the processing circuitry generates a second parameter using the reduced motion vector and a first bandpass component, the second parameter being a parameter for scaling the first bandpass component for compensating for a motion lost due to reduction of the motion vector with the first parameter with the first bandpass component,
in the second motion vector combining process the processing circuitry obtains a second combined vector by adding the first bandpass component scaled using the second parameter and the reduced motion vector,
in the nth parameter generation process the processing circuitry, using an (n−1)th combined vector and an (n−1)th bandpass component, generates an nth parameter that is a parameter for scaling the (n−1)th bandpass component when a motion lost due to reduction of the motion vector with the first parameter is compensated for with the (n−1)th bandpass component, where n=3, 4, . . . , NP+1, and
in the nth motion vector combining process the processing circuitry obtains an nth combined vector by adding the (n−1)th bandpass component scaled using the nth parameter and the (n−1)th combined vector, where n=3, 4, . . . , NP+1.
