PROBLEM TO BE SOLVED: To determine whether each of a plurality of headlamps that appear in an image obtained by capturing the surroundings of an own vehicle can be distinguishably displayed on a display unit.SOLUTION: A driving support system acquires an exposure time when a right rear side camera 11 captures an image and determines that it is an unidentifiable state when it is determined that the exposure time when the right rear side camera 11 has captured the image is equal to or larger than a reference value + α in a two-lamp separable state. The unidentifiable state is a state in which each of the plurality of lighting devices that appear in the image cannot be identified on a display unit. The same process is performed for an image captured by a left rear side camera 13 and an image captured by a rear camera 15. Then, the driver is notified of the unidentifiable state.SELECTED DRAWING: Figure 2 【課題】自車両の周囲を撮像した画像に写る複数の前照灯のそれぞれを表示部に識別可能に表示することの可否を判断する。【解決手段】右後側方カメラ１１が画像を取得した際の露光時間を取得し、二灯分離可能状態である場合に、右後側方カメラ１１が画像を取得した際の露光時間が基準値＋α以上であると判断された場合には、識別不能状態になったと判断する。識別不能状態は、画像に写る複数の灯火器のそれぞれを表示部上において識別不能な状態である。左後側方カメラ１３が撮影した画像、および後方カメラ１５が撮影した画像についても同様の処理を行う。そして、識別不能状態である旨をドライバに通知する。【選択図】図２
