PROBLEM TO BE SOLVED: To provide a dimmer, a light adjusting system and a mobile entity with which it is possible to prevent light from an emitter that cyclically emits light from being obstructed by an AC-drivable liquid crystal cell, and to prevent cyclic image recording by an imaging device from being obstructed by a liquid crystal cell.SOLUTION: An applied voltage adjustment unit 44 is capable of adjusting the voltage added to electrode parts 30, 31 to at least AC voltage under control of a frequency control unit 46. When information relating to detection of an emitter in proximity to a liquid crystal cell 25 and/or information relating to detection of imaging operation of an imaging device 17 that images light having passed through the liquid crystal cell 25 is inputted to a frequency control unit 46, the applied voltage adjustment unit 44 adjusts the voltage added to the electrode parts 30, 31 so that the frequency of the voltage added to the electrode parts 30, 31 becomes other than a frequency equal to the positive integral submultiple of 1 of emission cycle of the emitter and/or imaging cycle of the imaging device 17.SELECTED DRAWING: Figure 3

    【課題】周期的な発光を行う発光体からの光が交流駆動可能な液晶セルによって阻害されることを防ぎ、また撮影装置による周期的な画像の記録が液晶セルによって阻害されることを防ぐことができる調光装置、調光システム及び移動体を提供する。【解決手段】印加電圧調整部44は、周波数制御部46の制御下で、電極部30、31に付与される電圧を少なくとも交流電圧に調整可能である。印加電圧調整部44は、液晶セル25に接近する発光体の検出に関する情報及び/又は液晶セル25を通過した光を撮影する撮影装置17の撮影動作の検出に関する情報が周波数制御部46に入力された場合、電極部30、31に付与される電圧の周波数が発光体の発光周期及び/又は撮影装置17の撮影周期の正の整数分の1倍の周波数以外の周波数となるように、電極部30、31に付与される電圧を調整する。【選択図】図3
