  "textContent": "The present invention relates to a head-up display device that allows a viewer to view an actual scene overlapped with a virtual image, and that is capable of creating a display image with suppressed luminance variation. A MEMS scanner 20 scans synthesized laser light 500 two-dimensionally in the main scanning direction H and the sub-scanning direction V substantially orthogonal to the main scanning direction H. A controller unit 300 causes a first scan for generating a display image M on a transmissive screen 40 by scanning in the main scanning direction H at high speed while scanning in the sub-scanning direction V, and a second scan for scanning a position displaced more toward the sub-scanning direction V than the first scan on the transmissive screen 40.",
