To further reduce time required for adjustment of display luminance.SOLUTION: A luminance adjustment system 5 adjusts luminance of image display in a display device 4. The luminance adjustment system 5 comprises a control unit 50 that changes the luminance according to a value of illuminance in a target space. The control unit 50 has a gradually-changing mode that changes the luminance taking first time for the value of the illuminance and an abruptly-changing mode that changes the luminance taking second time which is shorter than the first time for the value of the illuminance as operation modes. The control unit 50 switches from the gradually-changing mode to the abruptly-changing mode using a sign of illuminance change in the target space as a trigger, and then operates in the abruptly-changing mode for at least fixed time.SELECTED DRAWING: Figure 1

    【課題】表示輝度の調整に要する時間の更なる短縮を図ること。【解決手段】輝度調整システム5は、表示装置4における画像表示の輝度を調整する。輝度調整システム5は、対象空間における照度の値に応じて輝度を変化させる制御部50を備える。制御部50は、動作モードとして、照度の値に対して第1時間をかけて輝度を変化させる徐変モードと、照度の値に対して第1時間より短い第2時間をかけて輝度を変化させる急変モードと、を有する。制御部50は、対象空間における急激な照度変化の予兆をトリガとして、徐変モードから急変モードに切り替えて、その後少なくとも一定時間は急変モードで動作する。【選択図】図1
