To provide a brightness adjustment device, a brightness control system, and a brightness control method, capable of implementing synchronization with respect to adjustment of brightness values of lamps.SOLUTION: An individual ECU (brightness adjustment device) adjusts a brightness value of a lamp. The individual ECU adjusts the brightness value of the lamp according to a brightness pattern in which a brightness value corresponding to a lapse time in one period is shown. The individual ECU acquires a synchronization count value (time value) with respect to the brightness pattern and changes an adjustment count rate (actual value) for the lapse time in one period on the basis of the acquired synchronization count value.SELECTED DRAWING: Figure 13

    【課題】ランプの輝度値の調整に関する同期を実現することができる輝度調整装置、輝度制御システム及び輝度制御方法を提供する。【解決手段】個別ECU(輝度調整装置)は、ランプの輝度値を調整する。個別ECUは、1周期中の経過時間に応じた輝度値が示されている輝度パターンに従ってランプの輝度値を調整する。個別ECUは、輝度パターンに関する同期カウント値(時間値)を取得し、取得した同期カウント値に基づいて、1周期中の経過時間の調整カウント値(実際値)を変更する。【選択図】図13
