PROBLEM TO BE SOLVED: To realize alert by irradiation of light onto the head part of a walker without providing uncomfortable feeling.SOLUTION: An image where the surrounding of a vehicle is captured is analyzed to irradiate light for predetermined irradiation time designed at 0.6 seconds or less onto the head part of a walker who should be alerted. In a case of long irradiation time of light, the walker feels uncomfortable by feeling brightness as bad faith, whereas in a case of short irradiation time, the walker never feels bad faith. In a case where the irradiation time is 0.6 seconds or less, it has been experimentally confirmed that a walker never feel bad faith when the light is irradiated onto his head part. In addition, even in a case where the irradiation time is short time of 0.6 seconds or less, when the light is irradiated onto the head part, a walker may certainly recognize irradiation of light. Therefore, certain alert may be realized by irradiation of light onto the head part of a walker without providing uncomfortable feeling to the walker.SELECTED DRAWING: Figure 1

    【課題】不快感を与えることなく歩行者の頭部に光を照射して注意喚起をする。【解決手段】車両の周囲を撮影した画像を解析して、注意喚起を要する歩行者の頭部に、0.6秒以下に設定された所定の照射時間の光を照射する。光の照射時間が長くなると、眩しくさせてやろうという悪意を歩行者が感じて不快になるが、照射時間が短ければ悪意を感じることはない。照射時間が0.6秒以下であれば、頭部に光を照射されても歩行者が悪意を感じることはないことが実験的に確かめられている。また、照射時間が0.6秒以下の短い時間でも、頭部に光を照射してやれば、歩行者は光が照射されたことを確実に認識することができる。このため、歩行者に不快感を与えることなく歩行者の頭部に光を照射して、確実に注意喚起することが可能となる。【選択図】図1
