Claim 2:
3. The motion vector generation apparatus according to claim 1, wherein the first parameter generation process includes:
an unnaturalness estimation process in which the processing circuitry estimates a third parameter, which is a coefficient for scaling the motion vector scaled by the first parameter to be the perceptual amount of motion, using a smallest value of a distance between a feature vector representing a perceptual representation of the warped image and a feature vector representing a perceptual representation of the projection result reproduction image which are obtained by applying a perceptual model, and obtains the smallest value as an unnaturalness estimate; and
a first parameter update process in which the processing circuitry updates the first parameter such that the perceptual difference is closest to a predetermined threshold.
