To provide an image projection device and an image projection method suppressing a sense of incongruity when visually recognizing a front display image even if a preceding vehicle approaches.SOLUTION: An image projection device (10) projecting a projection image to a wind shield (16) for displaying virtual images (17 and 18), is equipped with an image irradiating portion (11) that irradiates the projection image, optical portions (12, 13, 14, and 15) that irradiates the projection image to the wind shield (16) as image light, distance measuring means (20) that detects the overlapping of the virtual images (17 and 18) on a preceding vehicle, and a control portion (30) that controls a projection position of the projection image so as to avoid the overlapping of the virtual images (17 and 18) and the preceding vehicle, on the basis of a degree of the overlapping.SELECTED DRAWING: Figure 1

    【課題】先行車が接近した場合であっても、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投影する画像投影装置(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)に対して投影画像を画像光として照射する光学部(12、13、14、15)と、虚像(17、18)と先行車との重なりを検出する測距手段(20)と、重なりの程度に基づいて、虚像(17、18)と先行車との重なりを回避するように、投影画像の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
