PROBLEM TO BE SOLVED: To determine a visual field situation of an operator of a mobile object based on brightness or darkness that the operator feels to thereby present a suitable interval between mobile objects such as a recommended inter-vehicle distance of a vehicle.SOLUTION: A mobile object interval presentation device 10 includes: an image acquisition unit 17 for acquiring an image in which a travel direction of a mobile object is photographed; a visual field situation determination unit 19 for determining that a visual field situation is not good when an index of brightness based on the image is within a prescribed range and determining that a visual field situation is recovered when the brightness is maintained within the range and prescribed time has elapsed; and an inter-vehicle distance presentation unit 21 for presenting a recommended inter-vehicle distance between the mobile body and other mobile body based on determination of the visual field situation determination unit.SELECTED DRAWING: Figure 2
【課題】移動体の操縦者の視界状況を、操縦者が感じる眩しさまたは暗さに基づいて判定し、それによって自動車の推奨車間距離等の移動体同士の適切な間隔を提示する。【解決手段】移動体間隔提示装置10は、移動体の進行方向を撮影した画像を取得する画像取得部17と、前記画像に基づいた明るさの指標が所定範囲内である場合に視界状況が悪いと判定し、前記明るさが当該範囲内に維持されかつ所定時間が経過した場合に前記視界状況が回復したと判定する視界状況判定部19と、前記視界状況判定部の判定に基づいて、前記移動体と他の移動体との推奨車間距離情報を提示する車間距離提示部21と、を有する。【選択図】図2
