PROBLEM TO BE SOLVED: To effectively judge the danger of an approaching object in a device for monitoring the rear of a vehicle.SOLUTION: A vehicle rear monitoring device 1 includes: a camera 10 installed on the vehicle so as to image an image behind the vehicle at least with a horizontally wide angle; and a monitoring device 20 which outputs an alarm signal using the image imaged by the camera 10. The monitoring device 20 includes: high luminance region extraction means for extracting the position of a high luminance region for each frame of an image signal; approaching object detection means for detecting an approaching object from the positional change between frames in the high luminance region; danger judgment means for judging the danger of the approaching object from the size and the direction of the positional change; and alarm signal output means for outputting an alarm signal when the danger judgment means judges that the approaching object is dangerous.

    【課題】車両の後方を監視する装置において、接近物の危険性を効果的に判断する。【解決手段】車両用後方監視装置1は、車両に設置することで車両後方の画像を少なくとも左右広角に撮像するカメラ10と、カメラ10が撮像した画像によって警告信号を出力する監視装置20とを備える。監視装置20は、画像信号のフレーム毎に高輝度領域の位置を抽出する高輝度領域抽出手段と、高輝度領域のフレーム間の位置変化から接近物を検知する接近物検知手段と、位置変化の大小及び方向によって接近物の危険性を判断する危険性判断手段と、危険性判断手段が危険と判断した場合に警告信号を出力する警告信号出力手段とを備える。【選択図】図1
