To provide an imaging device that can reduce unnecessary event recording when a vehicle is traveling.SOLUTION: An image capturing unit 10 captures images of the interior or exterior of a vehicle to generate image data 31. A vibration detection unit 20 detects vibrations of the vehicle. A threshold setting unit 41 sets a threshold value to determine whether or not an event has occurred for which the image data 31 should be saved, based on a detected value of the vibration of the vehicle. An event detection unit 43 compares the detected value with the threshold value to detect the occurrence of the event. A recording control unit 44 records the image data 31 for a predetermined period of time before and after the occurrence of the event onto a recording medium 50 for storage. A threshold value updating unit 45 updates the threshold value to be used in the next unit interval based on the maximum detected value for each unit interval.SELECTED DRAWING: Figure 1 【課題】車両の走行時に不要なイベント記録が行われることを低減できる撮像装置を提供する。【解決手段】撮像部１０は車両の車内または車外を撮像して画像データ３１を生成し、振動検出部２０は車両の振動を検出する。閾値設定部４１は車両の振動の検出値に基づいて、画像データ３１を保存すべきイベントが発生したか否かを判定するための閾値を設定する。イベント検出部４３は検出値と閾値とを比較してイベントの発生を検出し、記録制御部４４はイベントの発生前後の所定期間の画像データ３１を保存用の記録媒体５０に記録する。閾値更新部４５は、単位区間ごとに、検出値の最大値に基づいて次の単位区間で用いるべき閾値を更新する。【選択図】図１
