Zusammenfassung:	PURPOSE:To warn a driver visually of being in dozing at a wheel by using a head up display mounted on a vehicle. CONSTITUTION:A main processor 12 finds a average value of variations of while line positions in plural detecting cycles as a drift degree in steering wheel operation to show a dozing degree according to while line position data obtained by applying image processing to a road surface image containing a white line to divide travel lanes. When the dozing degree is slight, a warning message is displayed in a flashing condition by a display tube 22 of a head up display, and when the dozing is in a medium degree, a buzzer 40 buzzes, and when the dozing is in a serious degree, oxygen-containing air is blown against a driver from a nozzle 32.
