To provide a defroster system capable of allowing output from a heater and also properly controlling the output of the heater so as to suppress windows from getting frosted.SOLUTION: The present invention relates to a defroster system X for a photographic device 10 for photographing the vehicle outside SP2 through a predetermined visual field region R set on a window 6 of a vehicle 1, and the defroster system has a heater 31 which heats the visual field region, and a controller 26 which applies voltage pulses of a supply voltage at a predetermined duty ratio to the heater to generate heat by the heater to prevent the visual field region from getting frosted, wherein the controller acquires a voltage value of the supply voltage and then sets the duty ratio of voltage pulses.SELECTED DRAWING: Figure 7

    【課題】窓の曇りを抑制するために、ヒータから出力を行うとともに、ヒータの出力を適切に制御することのできる曇り止めシステムを提供する。【解決手段】車両1の窓6に設定された所定の視野領域Rを介して車外SP2を撮影する撮影装置10のための曇り止めシステムXであって、視野領域を加熱するヒータ31と、ヒータに供給電圧の電圧パルスを所定のデューティ比でもって印加することによって、ヒータを加熱して視野領域が曇ることを防止する制御装置26と、を有し、制御装置は、供給電圧の電圧値を取得し、電圧パルスのデューティ比を設定する。【選択図】図7
