1. A motion vector generation apparatus for automatically adjusting a motion comprising:
a camera;
a projector; and
a computer comprising processing circuitry,
the processing circuitry configured to:
execute a first parameter generation process 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 the camera; and
execute a motion vector reduction process in which the processing circuitry scales the motion vector using the first parameter; and
displaying, based on the scaled motion vector, the projection result reproduction image using the projector for improved adjustment of motion on display.
