To appropriately output a warning when there is a pedestrian crossing a road ahead of a vehicle.SOLUTION: A warning controller 20 comprises: a video image acquisition unit 21 that acquires an out-vehicle video captured by an out-vehicle camera 11 and an in-vehicle video captured by a driver camera 12; a pedestrian recognition unit 22 that recognizes a pedestrian from the out-vehicle video; a driver motion detection unit 23 that detects a driver motion from the in-vehicle video; a determination unit 27 that determines whether or not a warning is required for a driver from the motion of the driver when a pedestrian is recognized on the basis of a recognition result of the pedestrian recognition unit 22 and a detection result of the driver motion detection unit 23; and a warning control unit 28 that performs control to give a warning to the driver when it is determined that a warning is required by the determination unit 27. The driver motion detection unit 23 detects a motion of placing a foot on a brake pedal from a motion of the driver's lower knee. The determination part 27 determines that a warning is required when a pedestrian is recognized by the pedestrian recognition unit and the driver's motion of placing his/her foot on the brake pedal is not detected from the motions of the driver.SELECTED DRAWING: Figure 1

    【課題】車両の前方に道路を横断する歩行者が存在するときに、警告を適切に出力すること。【解決手段】警告制御装置20は、車外カメラ11によって撮影された車外映像、および、運転者用カメラ12によって撮影された車内映像を取得する映像取得部21と、車外映像から歩行者を認識する歩行者認識部22と、車内映像から運転者動作を検出する運転者動作検出部23と、歩行者認識部22の認識結果と運転者動作検出部23の検出結果とに基づいて、歩行者が認識されたときに、運転者の動作から運転者に対して警告が必要であるかを判断する判断部27と、判断部27によって警告が必要であると判断された場合、運転者に対して警告を行うように制御する警告制御部28と、を備え、運転者動作検出部23は、運転者の膝から下の動きからブレーキペダルに足を置く動作を検出し、判断部27は、歩行者認識部によって歩行者が認識されて、運転者の動作から運転者がブレーキペダルに足を置く動作が検出されないとき、警告が必要であると判断する。【選択図】図1
