To provide an image projection device and image projection method, which enable effective suppression of an increase in temperature of an image irradiation unit due to external light using a simple configuration.SOLUTION: An image projection device (10) for projecting a virtual image via a display unit is provided, comprising an image irradiation unit (11) for irradiating image display light (GL) for forming a virtual image, and a reflective mirror (12) for guiding the image display light (GL) to a display unit, where the orientation of the reflective mirror (12) is changed so as to prevent light (SL) incident on the reflective mirror (12) from a direction of the display unit from entering the image irradiation unit (11) when a given condition is met.SELECTED DRAWING: Figure 1

    【課題】簡素な構成で外光による画像照射部の温度上昇を効果的に抑制することが可能な画像投影装置、および画像投影方法を提供する。【解決手段】表示部を介して虚像を投影する画像投影装置(10)であって、虚像を形成するための画像表示光(GL)を照射する画像照射部(11)と、画像表示光(GL)を表示部に導く反射鏡(12)と、を備え、所定の条件を満たす場合に、表示部の方向から反射鏡(12)に入射した光(SL)が画像照射部(11)に入射しないように反射鏡(12)の向きを変えることを特徴とする。【選択図】図1
