PROBLEM TO BE SOLVED: To provide an on-vehicle system that photographs a walker etc., more excellently while reducing the glare.SOLUTION: An on-vehicle system includes: an on-vehicle camera for photographing a peripheral space around a subject vehicle; a vehicle lighting fixture which irradiate the peripheral space with light; and a controller which controls the lighting state of the vehicle lighting fixture. The on-vehicle camera repeats a unit exposure cycle having an exposure time and a non-exposure time to photograph the peripheral space in the exposure time. The controller controls the lighting state of the vehicle lighting fixture so that the vehicle lighting fixture emits a plurality of pulse light beams in each of the exposure time and non-exposure time. Mean light intensity of a plurality of pulse light beams in the exposure time is set to be relatively high, and mean light intensity of a plurality of pulse light beams in the non-exposure time is set to be relatively low.SELECTED DRAWING: Figure 4 【課題】グレアを低減しつつ歩行者等をより良好に撮影する車載システムを提供する。【解決手段】自車両の周辺空間を撮影する車載カメラ、周辺空間に対して光を照射する車両用灯具、車両用灯具の点灯状態を制御する制御装置を含む。車載カメラは、露光時間と非露光時間を有する単位露光サイクルを繰り返して露光時間に周辺空間を撮影する。制御装置は、車両用灯具により、露光時間と非露光時間の各々で複数のパルス光を照射されるように車両用灯具の点灯状態を制御する。露光時間における複数のパルス光の光度の平均的な大きさが相対的に高く、非露光時間における複数のパルス光の光度の平均的な大きさが相対的に低く設定されている。【選択図】図４
