PROBLEM TO BE SOLVED: To record, by a drive recorder, unsteady driving that is carried out with a vehicle during travelling other than an action that a traffic light is ignored.SOLUTION: Drive recorders 100 and 300 comprise a color determination unit 151, a distance information acquisition unit 110, a recording unit 130, a movement information acquisition unit 120, an entry determination unit 152, and a recording control unit 153. The distance information acquisition unit 110 acquires distance information regarding a distance to an intersection in which the closest traffic light is installed from a vehicle. The movement information acquisition unit 120 acquires movement information regarding the movement of the vehicle. The entry determination unit 152 determines whether the vehicle enters the intersection or not based on the distance information and the movement information. The recording control unit 153 causes the recording unit 130 to start recording image data when the color determination unit 151 determines that a signal color of the closest traffic light from the vehicle and a signal color of the second closest traffic light from the vehicle are different, and when the entry determination unit 152 determines that the vehicle enters the intersection.SELECTED DRAWING: Figure 1

    【課題】ドライブレコーダで車両が走行中に行う、信号無視以外の非定常運転を記録する。【解決手段】ドライブレコーダ100,300は、色判断部151と、距離情報取得部110と、記録部130と、移動情報取得部120と、進入判断部152と、記録制御部153とを備える。距離情報取得部110は、自車両から1番目に近い信号機の設置されている交差点までの距離に関する距離情報を取得する。移動情報取得部120は、自車両の移動に関する移動情報を取得する。進入判断部152は、距離情報と移動情報とから自車両が交差点に進入するか否かを判断する。記録制御部153は、色判断部151が自車両に1番目に近い信号機の信号の色と自車両に2番目に近い信号機の信号の色とが異なると判断し、かつ、進入判断部152が、自車両が交差点に進入すると判断した場合に、記録部130に画像データの記録を開始させる。【選択図】図1
