To provide a projection-type display device, a control method of the projection-type display device, and a control program of the projection-type display device that can maintain constant display quality regardless of a window state and prevent an increase of manufacturing costs.SOLUTION: An HUD 4 mounted on a construction machine 100 having a window 6 that rotates and opens in a driver's cab 10A includes: a first projection display unit 2 and a second projection display unit 3 that are installed at different positions in the driver's cab 10A, spatially modulate light emitted from a light source on the basis of image information, and project image light spatially modulated to the window 6 to display a virtual image based on the image light; and a control unit 80 that receives the amount of rotation of the window 6 and causes either the first projection display unit 2 or the second projection display unit 3 to project the image light on the window 6 on the basis of the received amount of rotation.SELECTED DRAWING: Figure 3

    【課題】窓の状態によらず一定の表示品質を維持し且つ製造コストの増大を防ぐことのできる投写型表示装置、投写型表示装置の制御方法、及び投写型表示装置の制御プログラムを提供する。【解決手段】回動して開く窓6を運転室10Aに有する建設機械100に搭載されるHUD4は、運転室10A内の異なる位置に設置され、光源から出射される光を画像情報に基づいて空間変調し、空間変調された画像光を窓6に投写してこの画像光に基づく虚像を表示させる第一の投写表示部2及び第二の投写表示部3と、窓6の回動量を受信し、受信した回動量に基づいて、第一の投写表示部2と第二の投写表示部3の何れかから画像光を窓6に投写させる制御部80と、を備える。【選択図】図3
