To make it possible to increase a detection accuracy of a course obstruction action with respect to the own vehicle and to record an entire picture of the course obstruction action.SOLUTION: An on-vehicle dashboard camera comprises: an image capturing unit which is mounted on the own vehicle and captures an image in front of the own vehicle; a course obstruction action detection unit for detecting a course obstruction action with respect to the own vehicle in which a preceding vehicle follows a course change of the own vehicle and changes the course, the preceding vehicle traveling within a predetermined distance in front of the own vehicle; a repetition detection unit for detecting that the preceding vehicle has repeated the course obstruction action a predetermined number of times within a prescribed time after the course obstruction action is detected; and a recording control unit for prohibiting overwriting of a captured image captured by the image capturing unit from when the course obstruction action is first detected by the course obstruction action detecting unit until the preceding vehicle moves out of a field angle of the image capturing unit, and for recording the captured image in the recording unit in the case that the repeat detection unit detects that the course obstruction action has been repeated the predetermined number of times.SELECTED DRAWING: Figure 5

    【課題】自車両に対する進路妨害行為の検出精度を高めると共に、進路妨害行為の全貌を記録できるようにする。【解決手段】ドライブレコーダ装置は、自車両に搭載され自車両の前方を撮像する撮像部と、自車両の前方の所定距離以内を先行する先行車両が、自車両の進路変更に追従して進路変更する自車両への進路妨害行為を検出する進路妨害行為検出部と、進路妨害行為が検出されてから所定時間以内に、先行車両が進路妨害行為を所定回数繰り返したことを検出する繰返検出部と、繰返検出部により進路妨害行為が所定回数繰り返されたことが検出されたときに、進路妨害行為検出部により進路妨害行為が初めて検出されてから先行車両が撮像部の画角から外れるまでに撮像部により撮像された撮像画像を上書き禁止にして記録部に記録させる記録制御部と、を含む。【選択図】図5
