To provide an on-vehicle drive recorder device that accurately detects that the following vehicle passes.SOLUTION: An on-vehicle drive recorder device 10 includes a photographing unit 14 that captures the rear side of an own vehicle 12, a recording unit 16 that records an image captured by the photographing unit 14, and a passing detection unit 28 that detects lighting and blinking of headlights 26 of a following vehicle 24 that travels on the rear side of the own vehicle 12. Further, the on-vehicle drive recorder device 10 includes a control unit 30 that determines a passing threshold value, which is a threshold value of the illuminance change due to the blinking of the headlights 26 of the following vehicle 24 detected by the passing detection unit 28, based on a driving environment of the own vehicle, and records the image captured by the photographing unit 14 to the recording unit 16 when the illuminance change due to the blinking of the headlights 26 of the following vehicle 24 exceeds the passing threshold value.SELECTED DRAWING: Figure 2

    【課題】後続車のパッシングを精度良く検出する。【解決手段】車載ドライブレコーダ装置10は、自車両12の後方側を撮影する撮影部14と、撮影部14で撮影された映像を記録する記録部16と、自車両12の後方側を走行する後続車24の前照灯26の点灯及び点滅を検出するパッシング検出部28と、を備えている。また、車載ドライブレコーダ装置10は、パッシング検出部28によって検出された後続車24の前照灯26の点滅による照度変化の閾値であるパッシング閾値を自車両の走行環境に基づいて決定し、後続車24の前照灯26の点滅による照度変化がパッシング閾値を超えた際に、撮影部14で撮影された映像を記録部16に記録させる制御部30を備えている。【選択図】図2
