To facilitate grasping a contextual relationship between images without weakening the power of depth expression even when the eye position in the height direction of a viewer changes.SOLUTION: Provided is a head-up display device (HUD device 100) for projecting and displaying one or more virtual images V to a display area VA virtually set forward of a vehicle 10 by superimposition on the foreground, the HUD device comprising a display unit 120 for displaying the virtual image V and a control unit 160 for exercising control to display the virtual image V on the display unit 120. When the angle (depression angle) formed by a line parallel to a road surface, with the eye position in the height direction of a viewer 14 (eye point EP) taken as a point of reference, and a line linking the eye position in the height direction of the viewer 14 and the center of the display area VA is smaller than or equal to a prescribed threshold, the control unit 160 exercises control to change the display mode of the virtual image V before being displayed on the display unit 120.SELECTED DRAWING: Figure 2

    【課題】 視認者の高さ方向の目の位置が変化した場合であっても奥行きの表現力を弱めることなく画像間の前後関係の把握を容易にする。【解決手段】 車両10前方に仮想的に設定された表示領域VAに1以上の虚像Vを前景に重畳して投影表示するヘッドアップディスプレイ装置(HUD装置100)であって、虚像Vを表示する表示部120と、表示部120に虚像Vを表示する制御を行う制御部160と、を有し、制御部160は、視認者14の高さ方向の目の位置(アイポイントEP)を基準に路面に平行な直線と、視認者14の高さ方向の目の位置と表示領域VAの中心とを結ぶ直線とがなす角度(俯角)が所定の閾値以下の場合に、虚像Vの表示態様を変化させて表示部120に表示する制御を行う。【選択図】 図2
