Claim 12:
13. A method of controlling a road projection, the method comprising:
lighting a chromaticity variable road projection in a state in which a low beam by a warm white color and a cool white color of a chromaticity variable lamp is lit;
controlling a DMD that controls a mirror of a digital micromirror display (DMD) at a predetermined tilting angle by a lamp controller so that the warm white color light and the cool white color light of the chromaticity variable road projection are generated as a road surface radiation content contrasted thereto in chromaticity at the titling angle;
performing a content mode that radiates the road surface radiation content with a projection beam from the chromaticity variable road projection in a mirror fixing mode or a mirror conversion mode; and
radiating the projection beam as the low beam from the chromaticity variable lamp.
