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 support safe driving of vehicles.SOLUTION: An HUD 1 includes: projection display units 20U, 30U, and 40U that spatially modulate light emitted from a light source on the basis of image information, and project image light spatially modulated to projection surfaces 5A, 6A, and 7A; and a control unit 60 that controls the projection display units 20U, 30U, and 40U on the basis of a driver's line-of-sight. The control unit 60 performs line-of-sight tracking control that causes a projection display unit whose projection target of the image light is a projection surface intersecting with the driver's line-of-sight to project the image light, and further in the case where a change occurs from a state in which the driver's line-of-sight intersects with a first projection surface which is one of the projection surfaces to a state in which the driver's line-of-sight intersects with a second projection surface which is one of the projection surfaces, performs the line-of-sight tracking control and projection continuation control to cause the projection display unit whose projection target of the image light is the first projection surface to continue projection of the image light.SELECTED DRAWING: Figure 10

    【課題】乗り物の安全な運転を支援する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】HUD1は、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投写面5A,6A,7Aに投写する投写表示部20U,30U,40Uと、運転者の視線に基づいて投写表示部20U,30U,40Uを制御する制御部60と、を備える。制御部60は、運転者の視線と交わる投写面を画像光の投写対象とする投写表示部から画像光を投写させる視線追従制御を行い、更に、運転者の視線が投写面の1つである第一投写面と交わる状態から投写面の1つである第二投写面と交わる状態に変化した場合においては、視線追従制御と、第一投写面を画像光の投写対象とする投写表示部による画像光の投写を継続させる投写継続制御とを行う。【選択図】図10
