Description
例えば、特許文献1に開示されたHUD装置においては、1つの表示器にて視認者から見て距離の異なる2つの虚像が表示される。具体的には、HUD装置は、第1および第2の投影光を生成して出射する表示器と、第1および第2の投影光の結像距離を調整する結像位置調整ミラーと、結像位置調整ミラーからの第1および第2の投影光を受けて結像する第1および第2のスクリーンと、を備える。第1および第2のスクリーンは、それぞれ結像位置調整ミラーから異なる距離だけ離れた位置に設けられる。
表示光を出射する単一の表示器と、
前記表示光を受けて第1および第2の表示光を生成し、前記第2の表示光における自身から結像位置までの距離を前記第1の表示光における自身から結像位置までの距離よりも長く設定する結像位置調整部と、
前記第1の表示光の結像位置に設置される第1のスクリーンと、
前記第2の表示光の結像位置に設置される第2のスクリーンと、を備え、
前記第2のスクリーンの配光角は、前記第1のスクリーンの配光角よりも大きく設定される。
