More Information
Summary:To provide a head-up display device with which, while preventing breakage due to sunlight, it is possible to reduce time slots in which a user is unable to view a virtual image, and a method for controlling the same, contributing to Sustainable Development Goal 3: Ensure healthy lives and promote well-being for all at all ages.SOLUTION: A video display device 35 displays a video and emits the video light of the displayed video. A mirror (video light projection unit) M1 projects, and causes to be reflected, the video light emitted from the video display device 35 to a display region 5, so that the projected video light is visually recognized as a virtual image by a user. A shutter 68 is disposed on an optical path 30 of the video light, and switches between an optical path forming state in which the optical path of the video light is formed and an optical path non-forming state in which the optical path of the video light is not formed.SELECTED DRAWING: Figure 2 【課題】太陽光に伴う破損を防止しつつ、利用者が虚像を視認できない時間帯を削減することが可能なヘッドアップディスプレイ装置およびその制御方法を提供する。本発明によれば、持続可能な開発目標の「3すべての人に健康と福祉を」に貢献する。【解決手段】映像表示装置３５は、映像を表示し、表示した映像の映像光を出射する。ミラー（映像光投射部）Ｍ１は、映像表示装置３５から出射された映像光を表示領域５に投射して反射させることで、投射された映像光を虚像として利用者に視認させる。シャッター６８は、映像光の光路３０上に設けられ、映像光の光路を形成する光路形成状態、または映像光の光路を形成しない光路非形成状態に切り替える。【選択図】図２
