To provide an illuminance estimator that can estimate illuminance when a vehicle enters the inside of a structure.SOLUTION: An illuminance estimator 30 is a device that estimates the illuminance which is the brightness of the surroundings of a vehicle 10. The illuminance estimator 30 executes: acquiring front images which are images of the front of the vehicle; acquiring the luminance of a road surface area which is an area of a road surface on which the vehicle 10 travels, out of the front images; analyzing the front images to determine whether or not the vehicle 10 enters an inside of a structure that the vehicle 10 can enter; and acquiring a value corresponding to the luminance of the road surface area as the illuminance when it is determined that the vehicle enters the inside of the structure.SELECTED DRAWING: Figure 1

    【課題】構造物の内部に車両が進入する場合に照度を推定できる照度推定装置を提供すること。【解決手段】照度推定装置30は、車両10の周囲の明るさである照度を推定する装置である。照度推定装置30は、車両前方の画像である前方画像を取得することと、前方画像のうち、車両10が走行する路面が写っている領域である路面領域の輝度を取得することと、前方画像を解析することによって、車両10が進入可能な構造物の内部に車両10が進入するか否かを判定することと、構造物の内部に車両が進入すると判定している場合に、路面領域の輝度に応じた値を照度として取得することと、を実行する。【選択図】図1
