To provide a heater control system that does not incur excess power consumption in a vehicle or a decrease in the imaging performance of an onboard camera due to the fact that the heat generation temperature of a heater unit of the camera is properly controlled in response to the outside air temperature.SOLUTION: A control unit 400 of a heater control system 500 applies a prescribed high voltage to a heater unit 20 when a sensor 200 indicates at the time input of a heater switch 300 is accepted that the outside air temperature is less than a prescribed temperature, and applies a prescribed low voltage to the heater unit 20 when the sensor 200 indicates at the time input of the heater switch 300 is accepted that the outside air temperature is higher than or equal to the prescribed temperature.SELECTED DRAWING: Figure 1 【課題】外気温に応じてカメラのヒータ部の発熱温度が適切に制御されることにより、車両での余分な電力消費や車載カメラの撮像性能の低下を招くことのないヒータ制御システムを提供する。【解決手段】ヒータ制御システム５００は、制御部４００が、ヒータスイッチ３００の入力を受け付けた際に、外気温が所定の温度未満であることをセンサ２００が示している場合、所定の高電圧をヒータ部２０に印加するとともに、ヒータスイッチ３００の入力を受け付けた際に、外気温が所定の温度以上であることをセンサ２００が示している場合、所定の低電圧をヒータ部２０に印加する。【選択図】図１
