図1を参照しながら実施の形態1について説明する。図1は、実施の形態にかかるディスプレイ装置を搭載した自動車の上面図である。図に示す自動車900は、カメラ901およびディスプレイ装置1を有している。カメラ901は自動車900の周辺画像を撮像する複数のカメラである。図に示すように、自動車900は右側のドアミラーにカメラ901Rを有し、左側のドアミラーにカメラ901Lを有している。カメラ901Rは、自動車900の右側の周辺画像を撮像し、カメラ901Lは、自動車900の左側の周辺画像を撮像する。具体的には、カメラ901Rは、自動車900の右側から右後方を撮像し、カメラ901Lは、自動車の左側から左後方を撮像する。また、カメラ901は、自動車900の前方を撮影するために自動車900の前方を向いて配置されているカメラを含んでもよい。また、カメラ901は、自動車900の後方を撮影するために自動車900の後方を向いて配置されているカメラを含んでもよい。
次に、図10を参照しながら、実施の形態1の変形例1について説明する。図10は、実施の形態1の変形例1にかかるディスプレイ装置の照射範囲を上面から示した図である。本実施の形態にかかるディスプレイ装置1は、照射範囲が実施の形態1と異なる。
次に、図11を参照しながら実施の形態1の変形例2について説明する。本実施の形態は、メモリに領域分布情報が記憶されている点が上述の実施の形態1と異なる。また本実施の形態は、波長選択部141がメモリ40に記憶されている領域分布情報に基づいて動作する点が上述の実施の形態1と異なる。
次に、図12を参照しながら実施の形態2について説明する。図12は、実施の形態2にかかるディスプレイ装置の構成図である。実施の形態2にかかるディスプレイ装置2は、物体認識部12が警告判断部121を有している点、および波長選択部がレーザ光源制御部14に代えて画像処理部13に含まれている点が、上述の実施の形態1と異なる。
また、ステップS13の処理は、ステップS12で認識した物体が警告する対象であるか否かの判断としてもよい。例えば、認識した物体が自動車900と接触する可能性が無くとも、自動車900の近傍を走行している場合に、警告する対象としてもよい。
次に、図15を参照しながら実施の形態3について説明する。実施の形態3にかかるディスプレイ装置は、被照射領域に照射する画像を領域分布情報に基づいて生成し、生成した画像を表示する点が、実施の形態2と異なる。図15は、実施の形態3にかかるディスプレイ装置が画像を照射した例を示す図である。
