To provide an image projection device and an image projection method with which the sense of discomfort is suppressed when viewing a forward display image on a slope.SOLUTION: Provided is an image projection device (10) that irradiates a windshield (16) with a projection image in order to display virtual images (17, 18). The image projection device (10) comprises: an image irradiation unit (11) that irradiates a projection image; optical units (12, 13, 14, 15) that irradiate a projection image as image light in the direction of a viewpoint (52) via the windshield (16); a detection unit (31) that detects the inclination angle of a lane; a projection position adjustment unit that adjusts the projection position of the projection image on the windshield (16); and a control unit (30) that controls the projection position on the basis of the inclination angle.SELECTED DRAWING: Figure 1

    【課題】坂道において前方表示画像を視認する際の違和感が抑制された画像投影装置、および画像投影方法を提供する。【解決手段】虚像(17、18)を表示するためのウィンドシールド(16)に対して投影画像を照射する画像投影装置(10)であって、投影画像を照射する画像照射部(11)と、ウィンドシールド(16)を介して投影画像を画像光として視点(52)方向に照射する光学部(12、13、14、15)と、走路の傾き角度を検出する検出部(31)と、ウィンドシールド(16)に対する投影画像の投影位置を調整する投影位置調整部と、傾き角度に基づいて投影位置を制御する制御部(30)と、を備えることを特徴とする。【選択図】図1
