PROBLEM TO BE SOLVED: To provide a technique for displaying a stereoscopic virtual image more appropriately while maintaining visibility.SOLUTION: A virtual image display device 10 comprises: a projection unit 20 that includes a transmissive display 24 that generates display light by modulating illumination light and a driver 30 that rotates the display 24 to tilt the display 24 relative to the optical axis of the illumination light, and projects the display light onto a virtual image presentation plane to present a virtual image 50; an acquisition unit that acquires information for determining a rotation condition for the display 24; a determination unit that determines the rotation condition on the basis of the information acquired by the acquisition unit; and a drive control unit that controls the operation of the driver 30 on the basis of the determination made by the determination unit.SELECTED DRAWING: Figure 1
【課題】視認性を維持しながら立体感のある虚像をより適切に表示する技術を提供する。【解決手段】虚像表示装置10は、照明光を変調して表示光を生成する透過型の表示部24と、照明光の光軸に対して表示部24が傾斜するように表示部24を回動させる駆動部30とを含み、表示光を虚像提示面に投射して虚像50を提示する投射部20と、表示部24の回動条件を決定するための情報を取得する取得部と、取得部が取得する情報に基づいて回動条件を決定する決定部と、決定部の決定に基づいて駆動部30の動作を制御する駆動制御部と、を備える。【選択図】図1
