To increase the possibility of eliminating or preventing fogging of an imaging transparent area without a sensor for detecting a glass temperature, and reduce the possibility of wasteful power consumption by a camera heater.SOLUTION: A heater control device includes: a camera sensor that takes an image of the outside of a vehicle through an imaging transparent area of a window glass; and a camera heater that heats the imaging transparent area. The heater control device determines anti-fogging power for maintaining a temperature of the imaging transparent area at a target temperature so that the temperature of the imaging transparent area does not become lower than a dew point temperature estimated based on an indoor temperature and indoor humidity at the present point of time, by applying an outdoor temperature at the present point of time, a vehicle speed at the present point of time, and a target temperature equal to or greater than the dew point temperature, to a pre-set correlation between an outdoor temperature, a vehicle speed, and energization power to the camera heater, and the temperature of the imaging transparent area corresponding to the outdoor temperature, the vehicle speed, the energization power, and applies the anti-fogging power to the camera heater.SELECTED DRAWING: Figure 6

    【課題】ガラス温度を検出するためのセンサを不要とし、撮影透過領域の曇りを除去又は防止できる可能性を高め、カメラヒータが無駄な電力を消費してしまう可能性を低減すること。【解決手段】ヒータ制御装置は、ウィンドウガラスの撮影透過を通して車両の外部を撮影するカメラセンサと、撮影透過領域を加熱するカメラヒータと、を備える。ヒータ制御装置は、室外温度、車速及びカメラヒータへの通電電力と、当該室外温度、当該車速及び当該通電電力に対応する前記撮影透過領域の温度と、の間の予め設定された相関関係に、現時点の室外温度、現時点の車速及び「現時点の室内温度及び室内湿度に基いて予測された露点温度」以上の目標温度を適用することによって、撮影透過領域の温度が露点温度を下回らないように撮影透過領域の温度を目標温度に維持するための防曇電力を決定し、防曇電力をカメラヒータに通電する。【選択図】図6
