Document Type and Number:
WIPO Patent Application WO/2015/128985
Kind Code:
A1
Abstract:
A head-up display (2) is provided with a light source unit (4) and a combiner (9). A control unit (55) of the light source unit (4) causes a guidance image showing letters or a map to be displayed on the combiner (9) so that the image appears to overlap the background visible from a vehicle (Ve). The control unit (55) acquires a smoothness determination index (α), which is information pertaining to the degree of smoothness of the road surface on which the vehicle (Ve) is traveling, on the basis of a detection signal (Sd) received from a vibration sensor (3) and the traveling speed of the vehicle (Ve). The control unit (55) varies the size of the letters or map displayed on the combiner (9) in accordance with the smoothness determination index (α).
