Claim 8:
9. A motion vector generation method for automatically adjusting a motion, implemented by a motion vector generation apparatus that includes a camera, a projector, and processing circuitry, the method comprising:
a first parameter generation step in which the processing circuitry generates a first parameter that is a parameter for scaling a motion vector based on a perceptual difference between a projection result reproduction image which is an image that is obtained by photographing a projection target onto which a projection image obtained based on the motion vector has been projected and a warped image which is an image generated by distorting an image obtained by photographing the projection target by a perceptual amount of motion perceived by viewing the projection result reproduction image from a camera; and
a motion vector reduction step in which the processing circuitry scales the motion vector using the first parameter; and
a displaying step in which the processing circuitry displays, based on the scaled motion vector, the projection result reproduction image using the projector.
