Description
なお、メータ装置210及び車載モニター220は、表示装置に相当する。
以上、説明した一実施形態によれば、以下の効果を奏する。
この構成によれば、周囲が明るい場合にはその明るさに応じた輝度差Xだけ第1の虚像V1の輝度G1が第2の虚像V2の輝度G2よりも高く設定される。これにより、周囲が明るい場合における第1の虚像V1の誘目性を向上させることができる。
ここで、仮に周囲が暗い状況下で第1の虚像V1の輝度G1が高いと、第1の領域A1における第1の虚像V1を除く背景が光るため運転等の妨げとなることが懸念される。上記構成では、調光値I2が設定値A以下の場合には輝度G1と輝度G2と同一とすることで、周囲が暗い状況下で背景が視認されることが抑制される。
この構成によれば、調光値I2に基づき第2の虚像V2の輝度G2が決定され、この輝度G2を基準に第1の虚像V1の輝度G1が決定される。よって、この調光値I2が車載モニター220、メータ装置210等の表示装置に利用されることで、第2の虚像V2の輝度G2と車載モニター220、メータ装置210の発光輝度G3,G4とを同期させることができる。この際、第1の虚像V1の輝度G1は、他の輝度G2,G3,G4と異なるように変化するが、第1の虚像V1とメータ装置210、車載モニター220及び第2の虚像V2とで表示位置及び表示内容が異なるため、運転者Eに違和感を与えない。
この構成によれば、第1の虚像V1の誘目性を向上させつつ、車載表示システム1として、違和感なく、一体感のある発光態様を実現することができる。
なお、上記実施形態は、これを適宜変更した以下の形態にて実施することができる。
