To improve the accuracy of detection of tailgating against an own vehicle and to be able to record the entire tailgating behavior.SOLUTION: An on-vehicle drive recorder device includes: an image capturing unit that captures images of an area around an own vehicle; an other vehicle information acquisition unit that acquires other vehicle information concerning other vehicles in the vicinity of the own vehicle based on the captured images; an other vehicle scene determination unit that determines tailgating of another vehicle after determining that the other vehicle has interrupted based on the other vehicle information; and a recording control unit that allows, when the other vehicle is determined to have interrupted, the images captured by the image capturing unit at a predetermined time before and after the determination to be recorded in an overwrite-protected area of a recording unit, and further allows, when the other vehicle is determined to be tailgating, the images captured until the other vehicle moves out of the angle of view of the image capturing unit to be recorded in the overwrite-protected area.SELECTED DRAWING: Figure 5
【課題】自車両に対するあおり運転の検出精度を高めると共に、あおり運転行為の全貌を記録できるようにする。【解決手段】車載ドライブレコーダ装置は、自車両周辺を撮像する撮像部と、撮像画像に基づいて自車両周辺に存在する他車両に関する他車両情報を取得する他車両情報取得部と、他車両情報に基づいて、他車両の割り込みを判定した後に他車両のあおり運転を判定する他車両シーン判定部と、他車両が割り込んだと判定された際に、判定前後の所定時間において撮像部により撮像された撮像画像を記録部の上書き禁止領域に記録させ、さらに他車両があおり運転を行っていると判定された際に、他車両が撮像部の画角から外れるまでの撮像画像を上書き禁止領域に記録させる記録制御部と、を含む。【選択図】図5
