To determine weakening of a cognitive function of a driver on the basis of time from appearance of an object to detection of a danger avoidance motion to the object by the driver.SOLUTION: A processing device comprises: an image acquisition unit 10 which acquires a peripheral image of a vehicle; a detection unit 20 which detects appearance of an object from the acquired peripheral image; a detection unit 30 which detects a danger avoidance motion to the object by the driver of the vehicle; a measurement unit 40 which measures time from the appearance of the object detected by the detection unit 20 to detection of the danger avoidance motion to the object performed by the driver detected by the detection unit 30; and a determination unit 50 which determines weakening of a cognitive function of the driver from a measurement result of the measurement unit 40 and a predetermined threshold.SELECTED DRAWING: Figure 1
【課題】対象物の出現から運転者の対象物に対する危険回避動作の検出までの時間に基づいて、運転者の認知機能の衰えを判定する。【解決手段】車両の周辺画像を取得する画像取得部10と、取得された周辺画像から対象物の出現を検知する検知部20と、車両の運転者の対象物に対する危険回避動作を検出する検出部30と、検知部20による対象物の出現から検出部30による運転者の対象物に対する危険回避動作の検出までの時間を計測する計測部40と、計測部40の計測結果と、予め定めた閾値とから運転者の認知機能の衰えを判定する判定部50と、を備える。【選択図】図1
