To provide an imaging device for a vehicle and a heating device which can prevent an excessive heat generation amount of heating means in a predetermined time even when a determination factor of a heat generation amount changes significantly.SOLUTION: An imaging device for a vehicle includes: heating means which generates heat when a voltage of a power supply of a vehicle is applied; and a control device which changes a voltage application time as a time for applying a voltage of the power supply on the heating means within the predetermined time based on a level of a determination factor of a heat generation amount affecting a temperature of a window part. The control device executes one of first processing of stopping application of the voltage on the heating means until a time point when a predetermined time passes when a specific condition, which the level of the determination factor of the heat generation amount deviates from the level of the determination factor of the heat generation amount at a start time point of the predetermined time by a predetermined value or more, is established, and second processing of changing the voltage application time based on the level of the determination factor of the heat generation amount at the time point when the specific condition is established.SELECTED DRAWING: Figure 9
【課題】発熱量決定因子が大きく変化した場合であっても所定時間における加熱手段の発熱量が過剰になることを防止できる車両用撮影装置及び加熱装置を提供する。【解決手段】車両の電源の電圧が印加されたときに発熱する加熱手段と、窓部の温度に影響を及ぼす発熱量決定因子の所定時間の開始時点における大きさに基いて所定時間内において電源の電圧を加熱手段に印加する時間である電圧印加時間を変更する制御装置と、を備え、制御装置は、所定時間の開始時点から所定時間が経過する時点までに、発熱量決定因子の大きさが、所定時間の開始時点における発熱量決定因子の大きさから所定値以上乖離するという特定条件が成立したとき、電圧の加熱手段への印加を所定時間が経過する時点まで停止する第1処理、及び、特定条件が成立した時点における発熱量決定因子の大きさに基いて電圧印加時間を変更する第2処理、の何れか一方を実行する。【選択図】図9
